Definitions
- the field of the invention is that of planar antennas, of the type comprising at least one radiating element (also called "patch", planar pattern, radiating pattern or printed pattern) separated from a ground plane by a dielectric.
- radiating element also called "patch", planar pattern, radiating pattern or printed pattern
- Today is experiencing a considerable development of mobile networks and, more generally, of all "wireless” networks.
- these systems provide attractive responses on many points, such as connection flexibility, mobility, redeployment or the possibility of extending networks, this growth should continue to increase very significantly in the future.
- the radiating elements are part of the key components, for which the requested specifications are increasingly restrictive. It is of course constantly necessary to optimize all of the electrical performance of these antennas, but also to satisfy increasingly critical criteria, such as the size, the weight or the cost of these components.
- the object of the invention is in particular to provide a technique quite different from those used until today to increase the equivalent electrical length of the printed pattern (radiating element or patch) of the antenna, so as to obtain a very compact planar antenna.
- a complementary objective of the invention is to provide such a technique which is simple to implement and inexpensive.
- the invention also aims to provide such a technique which can be applied to any type of planar radiating structures, such as the basic antennas "half-wave patches" or “quarter-wave patches”, the antennas “annular patches” , antennas “patches with registered slots”, PIFA antennas (Planar Inverted-F Antenna) ...
- the antenna advantageously comprises, for at least one of the intermediate radiating elements, a sixth set of conductive pads connected to a second face of said intermediate radiating element and extending towards, without being connected to, another of said radiating elements which precedes said intermediate radiating element in a direction of travel from said superposition of the primary radiating element towards the upper radiating element.
- the antenna advantageously comprises a seventh set of conductive pads connected to a first face of said upper radiating element and extending towards, without being connected to, another of said radiating elements which precedes said upper radiating element along a direction of travel of said superposition of the primary radiating element towards the upper radiating element.
- Figure 12 is a sectional view of an antenna configuration with two stacked radiating elements, according to the invention
- Figure 13 is a sectional view of an alternative antenna to a radiating element according to the invention, in which the ground plane and the underside of the single radiating element have conductive pads
- Figure 14 is a sectional view of an alternative antenna with two radiating elements according to the invention, in which the ground plane and the two faces of the primary radiating element have conductive pads
- Figure 15 is a sectional view of another alternative antenna to a radiating element according to the invention, in which the ground plane is flat and the single radiating element is shaped
- the pads are distributed in an arrangement respecting this symmetry. It is therefore quite possible to operate the antenna according to two crossed linear polarizations, even in circular polarization. The solution developed, based on studs, is therefore not in itself an obstacle to the use of the antenna for any type of desired polarization.
- FIG. 6 presents an example of antenna obtained with this first embodiment of the method of manufacturing antenna according to the invention, based on the use of a three-dimensional metal part 7 (integrating the radiating element 1 and the studs 4) and positioning supports 8.
- the radiating element (patch) and the pads are produced in the following manner: a conducting part 171 (for example a metal foil) comprising a central part forming the radiating element 1 is produced; a plurality of conductive tabs are cut around the periphery of this conductive part (that is to say in eccentric parts of this part, adjacent to the central part); the conductive tabs are folded back, relative to the central part, so as to form conductive pads 4 connected to the radiating element 1. Once folded (for example orthogonally to the central part forming the radiating element), the conductive tabs 4 are for example positioned on the edges of a substrate forming a support element 170.
- FIG. 8 illustrates experimental results of this first prototype planar antenna according to the invention.
- the antenna was characterized by adaptation and transmission along the preferred axis of radiation.
- the measurement in transmission is based on the implementation of a simple link budget between the developed prototype and a reference antenna (in this case, a printed dipole). It should be noted that, since this link budget is not carried out in an anechoic chamber, the result presented only illustrates the radiation in a qualitative manner.
- a second prototype miniature antenna is a quarter-wave patch antenna, with ground feedback located on one of the sections support.
- This antenna was printed on a 25x25x 10mm substrate 3 and transferred to a ground plane of 100x100mm 2 .
- FIG. 10 illustrates experimental results of this second prototype planar antenna according to the invention.
- This second prototype was also characterized in adaptation and transmission. These results can be compared to those of a conventional quarter-wave patch type antenna, of geometry quite similar to that of the second prototype, except for the presence of non-through vias, and whose performance is given in the figure. he. As illustrated in these figures 10 and 11, there is again a clear shift towards the low frequencies for the antenna according to the invention (with non-through vias), hence the possibilities of significant reduction in the dimension of the radiant element (basic printed motif).
- the general principle of the invention (adding studs under the surface of a radiating element in order to reduce at least one physical dimension (length and / or width) for a fixed resonance frequency) can also be used.
- planar antennas with several stacked elements It will be recalled that such multi-element antennas are used for example for broadband applications or even multi-frequency applications.
- FIG. 12 shows a sectional view of an antenna configuration with two stacked radiating elements, according to the invention.
- the reduction in the resonance frequency is then very significant: this frequency in fact goes from 2.634GHz for the conventional antenna to 1.225GHz for the antenna of the invention, resulting in a decrease of more than 53%. This therefore leads to possibilities of ultra miniaturization of the basic printed pattern.
- the concept of the invention (addition of conductive pads) can also be applied simultaneously to the two faces of the same radiating element (except for the last of the superposition, that is to say the one furthest from the ground plane).
- FIG. 14 is a sectional view of an alternative antenna according to the invention, comprising a ground plane 142 and two radiating elements 141, 147.
- the ground plane 142 has conductive pads 144.
- the upper radiating element 147 does not have a stud.
- the primary radiating element 141 has first conductive pads 146 on its lower face and second conductive pads 145 on its upper face.
- FIG. 18 is a sectional view of another variant of antenna according to the invention, comprising a ground plane 180 and three radiating elements: a primary radiating element 181 (see definition above), an upper radiating element 183 (see definition above) and an intermediate radiating element 182.
- the general principle of the present invention can be implemented in any field of application which can use a planar antenna (mobile applications, satellite communications applications, wireless RF applications, etc.) in very different frequency ranges (from a few hundred MHz to a few tens of GHz).
