Definitions
- the present invention relates to an antenna of elongated shape for a small volume instrument, in particular a telephone watch, capable of receiving and transmitting radio messages on at least two frequencies of high and low values, this antenna being constituted, a starting from a power point, from a first radiant element whose length is tuned to the high frequency and from at least one second radiant element, following the first, the length of this second element added to that of the first having a total length tuned to the low frequency, the first and second radiant elements being connected together by a resonant circuit whose resonant frequency is chosen to limit the length of the antenna to its first element when the high frequency is active and for use the total length of the antenna when the low frequency is active
- each strand of the antenna comprises a first radiant element 3, then a resonant circuit 5 and finally a second radiant element 4
- the antenna is designed to be tuned on two different frequencies, for example 28 and 21 MHz
- the length L1 of the first radiant element 3 is adapted to the frequency of 28 MHz (or more exactly to the quarter of the wavelength of this frequency)
- the length L2 of the second radiant element 4 added to the length L1 of the first element leads to a radiant element of length L3 adapted to the frequency of 21 MHz (or as p read high at a quarter of the wavelength of this frequency)
- the resonant circuit 5 is an oscillating circuit comprising a coil 6 and a capacitor 7 connected in parallel The values of these
- the antenna is made up by means of tubes forming the radiant elements 3 and 4, these tubes being joined by a sleeve containing the resonant circuit 5 produced by means of discrete components, either a coil or inductor 6 and a capacitor 7
- the frequencies used in small volume instruments, for example a mobile phone or even a phone watch are much higher than those mentioned above If the principle of adapting the antenna to at least two different frequencies may remain the same as described above, the technique used for these short wavelengths must be adapted to the antenna used This antenna must be able to operate at least on the official frequencies standardized for example by the GSM system (Group Special Mobile) which provides a high frequency f h equal to 1.9 GHz and a low frequency f b equal to 900 MHz
- the antenna is characterized by that the first and second radiant elements each have a conductive tape of substantially rectangular shape and that the resonant circuit comprises the combination of an inductor and a capacitor, said inductor being a substantially straight narrow strip formed integrally with at least one of said ribbons and linked to this ribbon by one of its ends.
- document EP 0 470 797 describes an antenna capable of adapting to several frequencies.
- the document WO 99/03168 describes a compact antenna capable of adapting at least to a low frequency and a high frequency, this antenna being in particular intended to equip mobile telephony devices
- the antenna has two radiant elements connected together by a resonant circuit which can be represented diagrammatically as the paralleling of a capacitor and an inductor.
- this resonant circuit and in particular the inductance in the form of a relatively wide printed ribbon in the form of a meander
- the capacity value of the resonant circuit is determined HERE by the parasitic capacity present between the “turns” or meanders of the inductance
- a drawback of this solution resides in the fact that the adjustment of the resonant frequency of the resonant circuit is difficult to effect Indeed , if you wish to modify the inductance value of the resonant circuit, it is necessary to modify the width and / or the length of the meander By carrying out such an operation, the value of the parasitic capacitance of the resonant circuit is affected at the same time
- the solution according to the present invention has the advantage of being able to easily adjust the resonant frequency of the resonant circuit by acting independently on the value of the inductance or on the value of the capacitor.
- the inductance formed by a narrow track substantially rectilinear does not appreciably affect the capacity value of the resonant circuit
- a narrow track for the inductance has the advantage of a higher inductance at equal size compared to the solution envisaged in document WO 99/03168 characteristics and advantages of the invention will now emerge from the description which follows, made with reference to the appended drawing and giving, by way of explanation but in no way limiting, several advantageous embodiments of the invention, drawing in which

- FIG. 3 illustrates a second embodiment of the antenna according to the invention, this antenna being self-supporting and integrated for example into a telephone watch,
- FIG. 4 shows a third embodiment of the antenna according to the invention, this antenna forming an integral part of a printed circuit
- Figure 5 shows a fourth embodiment of the antenna according to the invention
- - the FIG. 6 is a section along the line VI-VI visible in FIG. 5
- FIG. 7 shows a fifth embodiment of the antenna according to the invention, this embodiment being a variant of the antenna mounted in FIG. 5,
- - Figure 9 shows a sixth embodiment of the antenna of the invention

- FIG. 11 is a plan view of the antenna of the invention, view on which are plotted the level curves of the electrical component of the electromagnetic field when the antenna works at the high frequency f h
- the antenna 1 in question has an elongated shape. It is intended for an instrument of small volume, in particular for a telephone housed in a watch, this telephone being capable of receiving and transmitting radio messages
- the antenna 1 is also capable of working on at least two frequencies of values high f h and low f b and is constituted, from a supply point 2, a first radiant element 3 whose length L1 is tuned to the high frequency f h and at least one second radiant element 4 which follows the first, the length L2 of this second element 4 added to that of the first having a total length L3 tuned to the low frequency f b
- the same figures 2 to 9 show that the first and second radiant elements 3 and 4 are connected together by a resonant circuit 5
- the resonance frequency f r of this resonant circuit 5 is chosen to limit the length of the antenna 1 to its first radiant element 3 when the high frequency f h is active and to use the total length L3 of the antenna when the low frequency e f D is active
- the invention is remarkable first in that the first and second radiant elements 3 and 4 each have a conductive strip of substantially rectangular shape, these strips being placed one after the other Then the invention is remarkable in that the resonant circuit 5 comprises the combination of an inductor 6 and a capacitor 7, 7 'this inductor 6 being a substantially substantially narrow narrow strip formed integrally with at least one of said ribbons and linked to this ribbon by one of its ends 8, 8 'In this respect, all of Figures 2 to 9 show that the end 8 of the inductor 6 is linked to the ribbon 3 and that the inductor 6 is formed integrally with one of the ribbons, in this case with the ribbon 3
- Figures 2 to 8 show that the inductor 6 and the capacitor 7, 7 'are connected in parallel Under these conditions, it will be understood that the value of each of these components will be chosen so that the resonant circuit has a resonant frequency f r substantially equal to the high operating frequency f h of the antenna Indeed, as already mentioned in the preamble to this description, the impedance of the resonant circuit then has a maximum during resonance and if the resonant circuit is tuned to the high frequency f h , it will represent as a plug or a barrier not letting pass said high frequency As the first radiant element 3 has a length granted to this high frequency, the antenna will be limited to this first radiant element or first ribbon 3 if the high frequency is active Unlike this, if it is the low frequency which is active to send or receive messages, the resonant circuit t 5 will present at this frequency a minimum impedance, allowing said low frequency to pass As the sum of the lengths L1 and L2 of the strips 3 and 4 is given to the
- FIG. 2 illustrates a first embodiment of the invention
- the first and second ribbons 3 and 4 are self-supporting and therefore do not rest on any substrate, although fixing means 9 are provided for attaching the antenna to the instrument in which it is implanted This naturally assumes that the ribbons have a certain thickness to ensure a certain mechanical rigidity in the whole assembly.
- the inductor 6 is a substantially straight narrow strip connected by its first end 8 to the first ribbon 3 and by its second end 8 'to the second ribbon 4
- the inductor 6 is formed integrally with the two ribbons 3 and 4
- the capacitor 7 on the other hand is a discrete component, executed separately from the ribbons constituting the antenna and having first and second terminals 10 and 10 'welded respectively to the first and second strips 3 and 4
- the antenna is supplied by a wire (not shown) welded in a passage 2 practical in the first strip 3
- FIG. 3 illustrates a second embodiment of The invention
- first and second ribbons 3 and 4 which are self-supporting and are separated by an inductor 5 and a discrete component forming the capacitor 7
- the antenna is wound around a box 26 housing the electronic circuits necessary for the functioning of the instrument
- FIG. 4 shows a third embodiment of the invention Compared with the first and second modes, this third mode is characterized in that the first and second tapes 3 and 4 rest on an insulating substrate 11, for example Kapton (registered trademark) to form a printed circuit Inductance 6 is a narrow track printed on the substrate 1 It is connected by its first end 8 to the first ribbon 3 and by its second end 8 'to the second ribbon 4 It therefore forms an integral part ribbons 3 and 4 To form the resonant circuit 5, the capacitor 7, 7 'associated with the inductor 6 can take different forms
- FIG. 4 A first form of capacitor is illustrated in FIG. 4
- This capacitor actually comprises two capacitors 7 and 7 'located on either side of the inductor 6 These two capacitors are connected in parallel and give symmetry to the whole of the resonant circuit This symmetry is generally desirable and will be preferred to a non-symmetrical mounting as can be seen in FIG. 2
- the capacitor 7, 7 'comprises a first frame 12, 12' printed on the substrate 11 and connected to the first ribbon 3 II further comprises a second frame 13, 13 ′ also printed on the substrate 1 1 and connected to the second ribbon 4 As FIG.
- each of these first and second frames has the shape of a comb whose teeth interpenetrate without touching The capacity is created here in the space existing between the teeth We will also speak of an interdigitated capacity
- the first ribbon 3 is supplied by a conductor ur (not shown) welded to the feed point 2
- This third embodiment illustrated by FIG. 4 shows how, according to the invention, a dual-frequency antenna can be produced simply and above all economically This antenna is in fact entirely produced in a single printed circuit, the well-known chemical etching producing all at once the ribbons 3 and 4, the inductor 6 and the capacitor 7, 7 'This antenna can therefore be produced at an extremely low cost since no discrete component is necessary to create the resonant circuit 5
- FIG. 5 A second form of capacitor associated with a printed inductor 6 is shown in Figures 5 and 6, Figure 5 being a plan view of the antenna and Figure 6 a section along the line Vl-Vi of Figure 5
- Figures 5 and 6 explain a fourth embodiment of the invention
- the capacitor comprises the placing in parallel of two capacitors 7 and 7 'situated on either side of the inductor 6 and each formed of a discrete component having a first terminal 14 and 14 ' soldered on the first ribbon 3 and a second terminal 15 and 15 'soldered on the second ribbon 4.
- This fourth embodiment has another feature which will be discussed below
- FIGS. 7 and 8 A third form of capacitor associated with a printed inductor is shown in FIGS. 7 and 8, FIG. 7 being a plan view of the antenna and FIG. 8 a section along line VIII-VIII of FIG. 7
- the capacitor comprises the paralleling of two capacitors 7 and 7 'located on either side of the inductor 6
- the capacitor 7 in turn comprises the placing in series of first and second capacitors 16 and 17 each comprising a common frame 18 printed under the insulating substrate 1 1, this frame 18 extending partially, on the one hand under the first strip 3 to form the first capacitor 16 and on the other hand under the second ribbon 4 to form the second capacitor 17
- the capacitor 7 ' also includes the placing in series of first and second capacitors 16' and 17 'each comprising a common frame 18' printed under the insulating substrate 11, this frame 18 'extending partially, on the one hand under the first ribbon 3 to form the first capacitor 16' and on the other hand under the second ribbon 4 to form the second capacitor 18 '.
- the substrate 11 serves as a dielectric for each of the capacitors mentioned.
- This fifth embodiment is almost as economical as that described in connection with FIG. 4, since the entire antenna 1 and the resonant circuit 5 can be made by chemical etching of a double-sided printed circuit and this without adding discrete welded components on the ribbons
- the first and second ribbons 3 and 4 are arranged at a determined distance A from a ground plane 19, that the initial part 20 of the first ribbon 3 is short-circuited in this plane by a bridge 27 and that the final part 21 of the second ribbon 4 is left free
- the ground plane 19 is assimilated to the housing 26 which is metallic As shown in FIGS.
- the antenna is supplied by a coaxial cable 28 which includes a internal conductor 29 isolated from the ground plane 19 and connected to the supply point 2 of the first ribbon 3, this supply point being distant from the bridge 27 short-circuiting said first ribbon 3 and said ground plane 19
- the coaxial cable further comprises a conductor or shielding 30 connected to the ground plane 19
- the distance A between the ribbons 3 and 4 and the ground plane 19 is maintained by the fact that the ribbons are self-supporting and therefore sufficiently rigid to ensure this distance
- the distance A is maintained by a foam 31 bonded to the substrate 11 and to the ground plane 19
- An antenna as shown in FIG. 6, but being adapted to only one frequency and consequently having only one conductive tape is known by the Anglo-Saxon name "Planar Inverted-F Antenna” or PIFA
- This variant was the subject of a European patent application No.
- the multifrequency antenna of the present invention can be applied both to a PIFA antenna and to an antenna located without reference to an immediate ground plane, as illustrated in FIG. 2 or in FIG. 4 for example
- FIG. 9 shows a sixth embodiment of the invention This mode is part of the second category of antenna, mentioned above where the inductor 6 and the capacitor 7 are connected in series. It will be understood that the value of each of these components will be chosen to have a resonance frequency f r substantially equal to the low frequency f b of the antenna operating.
- the resonant circuit 5 HERE has a minimum impedance at resonance II follows that when the low frequency f b is active, the resonant circuit 5 does not oppose any resistance to this frequency
- the length of the ribbon 4 is then added to the length of the ribbon 3 and the antenna is adapted to the low frequency f 0
- the resonant circuit has a very high impedance preventing the propagation of f h beyond the first ribbon 3
- FIG. 9 shows a practical example of construction of the antenna with a resonant circuit 5 comprising the placing in series of an inductance 6 and a capacitor 7
- the first and second strips 3 and 4 rest on an insulating substrate 11 to form a printed circuit
- the inductor 6 is a narrow track printed on the substrate and connected by its first end 8 to the first ribbon 3
- the second end 8 'of the inductor 6 is connected to a first armature 12 of a capacitor 7 while '' a second armature 13 of the same capacitor 7 is - y -
- first and second frames 12 and 13 have the shape of a comb, the teeth of which interpenetrate without touching.
- the same remark can be made HERE as that expressed in connection with FIG. 4
- the ribbons 3 and 4 as well as the resonant circuit 5 are printed on a substrate 11 without the addition of external components. We are therefore dealing with a very inexpensive antenna produced by simple chemical attack on a printed circuit.
- FIGS. 10 and 11 are plan views of the antenna according to the invention drawn over a length X of ⁇ 50 mm and a width Y of ⁇ 10 mm These figures show the contour lines, expressed in dB, of the electrical component Ez of the electromagnetic field perpendicular to the plane of the antenna and measured close to this plane
- the resonant circuit 5 is an oscillating circuit comprising the placing in parallel of an inductance 6 and a capacitor 7 as has been described more top II resonates at the high frequency f h
- Figure 10 shows the behavior of the antenna 1 when the low frequency f b is active
- the antenna is used over a large part of its length and ignores the presence of the resonant circuit whose impedance is very low
- Figure 11 shows the behavior of the antenna 1 when the high frequency f h is used
- the antenna is used on its left part,
- All the embodiments of the antenna described above are suitable for a dual-frequency antenna. It is clear that the invention is not limited to the use of two frequencies. For example, if a third additional frequency, even lower than that designated above by f b , must be radiated by the antenna, it will be understood that it suffices to have, after the second ribbon 4, a third ribbon and a second resonant circuit between the second and the third ribbon The length of this third ribbon will be chosen so that added to the length of the first two, the total length of the antenna is tuned to the new lower frequency In this case, the resonance frequency of the second resonant circuit will be chosen af b
