Description
1 8 2 Sammanfattning av uppfinningen Ett ändamål med föreliggande uppfinning är att åstadkomma en antennanordning för användning i en radiokommunikationsanord- ning, företrädesvis en bärbar radiokommunikationsanordning, varvid den elektriska kopplingen mellan sändnings- och mottag- ningsantennelement minimeras. SUMMARY OF THE INVENTION An object of the present invention is to provide an antenna device for use in a radio communication device, preferably a portable radio communication device, whereby the electrical connection between transmitting and receiving antenna elements is minimized.
Uppfinningen baseras på insikten, att då ett antennelement har balanserad matning och ett annat antennelement har obalanserad matning blir det möjligt att utforma de två antennerna på ett sätt där kopplingen mellan antennerna kan bli lägre än med två antenner som båda har obalanserad eller balanserad matning.The invention is based on the insight that when one antenna element has balanced supply and another antenna element has unbalanced supply, it becomes possible to design the two antennas in a way where the connection between the antennas can be lower than with two antennas that both have unbalanced or balanced supply.
En fördel med ett balanserat och obalanserat antennpar är att med en balanserad ingång till mottagarelektronikkretsar och en obalanserad matning från en utgångsförstärkare, uppnås lägre förluster och förbättrad matchning till mottagaren/sändaren.An advantage of a balanced and unbalanced antenna pair is that with a balanced input to receiver electronics circuits and an unbalanced supply from an output amplifier, lower losses and improved matching to the receiver / transmitter are achieved.
Enlig föreliggande uppfinning åstadkommes en antennanordning såsom definierad i bifogade patentkrav 1.According to the present invention there is provided an antenna device as defined in appended claim 1.
Vidare åstadkommes en radiokommunikationsanordning inne- fattande en sådan antennanordning.Furthermore, a radio communication device is provided comprising such an antenna device.
Ytterligare föredragna utföringsformer är definierade i bifo- gade patentkrav.Further preferred embodiments are defined in the appended claims.

Detaljerad beskrivning av uppfinningen I det följande kommer en detaljerad beskrivning av föredragna utföringsformer av en antennanordning enligt uppfinningen att ges. Vid de flertalet utföringsformer som beskrives häri ges samma hänvisningssiffror till identiska delar vid de olika utföringsformerna.Detailed Description of the Invention In the following, a detailed description of preferred embodiments of an antenna device according to the invention will be given. In the majority of embodiments described herein, the same reference numerals are given to identical parts in the various embodiments.
En balanserad matning definieras som då en transmissionsled- ning innefattande två ledare i närvaro av jord kan arbeta på ett sådant sätt, att då spänningarna hos de två ledarna vid samtliga tvärplan har samma storlek och motsatt polaritet av- seende jord har strömmarna i de två ledarna väsentligen samma storlek och motsatt riktning. En obalanserad matning definie- ras som en matning som ej uppfyller ovanstående villkor.A balanced supply is defined as when a transmission line comprising two conductors in the presence of earth can operate in such a way that when the voltages of the two conductors at all transverse planes have the same magnitude and opposite polarity with respect to earth, the currents in the two conductors essentially the same size and opposite direction. An unbalanced feed is defined as a feed that does not meet the above conditions.
Hänvisning görs nu till fig. 1, där en antennanordning eller -modul, allmänt betecknad 1, innefattar ett tryckt kretskort (PCB) 10 med därpå monterade kretsar för sändardelen 24 och mottagardelen 34 av det elektroniska kretsarrangemanget hos en mobiltelefon (ej visad i figurerna). Nämnda PCB 10 fungerar också som jordplan för en plan, inverterad F-antenn (PIFA), vars strålande element betecknas 20. Det strålande elementet 20 är placerat på avstånd från nämnda PCB 10 och väsentligen 51-8 706 §11= :;:: 4 parallellt därmed och innefattar en matningsdel 22 ansluten till ett matningselement hos sändardelen 24 och en jordnings- del 23 ansluten till ett jordelement hos sändardelen. Sålunda fungerar nämnda PIFA 20 som en sändande antenn hos anordningen 1.Reference is now made to Fig. 1, where an antenna device or module, generally designated 1, comprises a printed circuit board (PCB) 10 with thereon mounted circuits for the transmitter part 24 and the receiver part 34 of the electronic circuit arrangement of a mobile telephone (not shown in the figures). . The PCB 10 also functions as a ground plane for a plane, inverted F-antenna (PIFA), the radiating element of which is designated 20. The radiating element 20 is located at a distance from the PCB 10 and substantially 51-8 706 §11 =:; :: 4 parallel thereto and comprises a feed part 22 connected to a feed element of the transmitter part 24 and a ground part 23 connected to a ground element of the transmitter part. Thus, the PIFA 20 functions as a transmitting antenna of the device 1.
Nämnda PIFA 20 är en elektrisk antenn med obalanserad matning där jordningsdelen 23 är ansluten direkt till jord. Anslut- ningen kan alternativt föreligga via ett matchningsnät inne- fattande punktformiga eller distribuerade induktorer och/kondensatorer.The PIFA 20 is an electrical antenna with unbalanced supply where the earthing part 23 is connected directly to earth. The connection may alternatively be via a matching network comprising point-shaped or distributed inductors and / or capacitors.
Antennanordningen 1 innefattar också en loopantenn betecknad 330. Loopantennen är tillverkad av en ledande tråd som bildar en slinga eller loop i ett plan parallellt med nämnda PCB 10 och även med det strålande elementet 20 och som ligger väsent- ligen i PIFA-elementets plan, omgivande PIFA-elementet.The antenna device 1 also comprises a loop antenna designated 330. The loop antenna is made of a conductive wire which forms a loop or loop in a plane parallel to said PCB 10 and also with the radiating element 20 and which lies substantially in the plane of the PIFA element, surrounding The PIFA element.
Kopplingen mellan PIFA-antennen 20 och loopantennen 330 med balanserad matning är liten eftersom nämnda PIFA 20 ger ett väsentligen elektriskt fält vinkelrätt mot antennplanet och loopantennen 330 i balanserad matning ger ett väsentligen mag- netiskt fält med en riktning vinkelrät mot antennplanet. Där- för har antennerna låg inbördes koppling.The coupling between the PIFA antenna 20 and the balanced feed loop antenna 330 is small because the PIFA 20 provides a substantially electric field perpendicular to the antenna plane and the balanced feed loop antenna 330 provides a substantially magnetic field with a direction perpendicular to the antenna plane. Therefore, the antennas have low interconnection.
Loopantennen 330 är vid sina ändar 332, 333 ansluten till en respektive ingång på mottagardelen 34. I figuren anges den ena ingången som positiv och den andra som negativ. Loopantennen 330 är balanserad, d.v.s. den matas med motsatta signaler, varigenom den fungerar som magnetisk antenn.The loop antenna 330 is connected at its ends 332, 333 to a respective input on the receiver part 34. In the figure, one input is indicated as positive and the other as negative. The loop antenna 330 is balanced, i.e. it is fed with opposite signals, whereby it acts as a magnetic antenna.
Alternativt skulle loopantennen 330 kunna ersättas med en öppen loop, d.v.s. en dipolantenn.Alternatively, the loop antenna 330 could be replaced with an open loop, i.e. a dipole antenna.
Vid en alternativ andra utföringsform som visas i fig. 2 har loopantennen ersatts av en dipolantenn 230 innefattande två 5«18' 7(]6 š:fit?u}{}:å'.L:å':í:ï 5 trådlika delar 231a, 231b. Dessa delar omger PIFA-elementet 20 på ömse sidor om detta och i nivå med det väsentligen plana elementet 20. Liksom vid den första utföringsformen har dipol- antennen 230 balanserad matningsdel.In an alternative second embodiment shown in Fig. 2, the loop antenna has been replaced by a dipole antenna 230 comprising two wires. These parts surround the PIFA element 20 on either side thereof and at the level of the substantially planar element 20. As in the first embodiment, the dipole antenna 230 has a balanced feed portion.
De tvâ trådlika delarna 23la och 231b visas som tvâ delar av samma längd men företrädesvis är längden hos ett av elementen, t.ex. 23lb, anpassad för att justera dipolantennens 230 impe- dans och/eller resonansfrekvens.The two wire-like parts 23la and 231b are shown as two parts of the same length, but preferably the length of one of the elements, e.g. 23lb, adapted to adjust the impedance and / or resonant frequency of the dipole antenna 230.
Vid en alternativ tredje utföringsform som visas i fig. 3 är den mottagande antennen en loopantenn 30 med sina ändar 32, 33 anslutna till respektive ingång på mottagardelen. I motsats till den utföringsform som beskrivits ovan under hänvisning till fig. 1 är dock denna loopantenn anordnad i ett plan vin- kelrätt mot nämnda PCB 10 och PIFA-element 20.In an alternative third embodiment shown in Fig. 3, the receiving antenna is a loop antenna 30 with its ends 32, 33 connected to the respective input of the receiver part. In contrast to the embodiment described above with reference to Fig. 1, however, this loop antenna is arranged in a plane perpendicular to said PCB 10 and PIFA element 20.
De tre utföringsformerna som visas i fig. 1-3 är samtliga grundläggande konfigurationer för en antennanordning enligt uppfinningen. De har alla gemensamt att det finns en obalan- serad PIFA-antenn som fungerar som sändande antenn och en mot- tagande antenn med balanserad matning, som är antingen en loop- eller en dipolantenn. I fig. 1 och 2 omger dessutom antennen 330, 230 med balanserad matning PIFA-antennen 20.The three embodiments shown in Figs. 1-3 are all basic configurations of an antenna device according to the invention. What they all have in common is that there is an unbalanced PIFA antenna that acts as a transmitting antenna and a receiving antenna with balanced supply, which is either a loop or a dipole antenna. In Figs. 1 and 2, the balanced supply antenna 330, 230 also surrounds the PIFA antenna 20.
I fig. 4-6 visas varianter av de grundläggande konfiguration- erna. Den i fig. 4 visade utföringsformen liknar den i fig. 1 men med skillnaden att anslutningarna 432, 433 till loop- antennen 430 är utförda på en sida av PIFA-elementet 20 mot- stående PIFA:ns matnings- och jordningsdelar 22, 23. Detta ger fördelen att kopplingen till nämnda PCB påverkas och kan an- passas till en önskad design.Figures 4-6 show variants of the basic configurations. The embodiment shown in Fig. 4 is similar to that in Fig. 1, but with the difference that the connections 432, 433 to the loop antenna 430 are made on one side of the PIFA element 20 opposite the feed and ground parts 22, 23 of the PIFA. This gives the advantage that the connection to the said PCB is affected and can be adapted to a desired design.
Den i fig. 5 visade utföringsformen liknar den i fig. 3 men uppvisar skillnaden att loopantennen 530 befinner sig på en sida av PIFA-elementet 20 motstående PIFA:ns matnings- och 518 m :v :;:: 6 jordningsdelar 22, 23. Detta ger fördelen att kopplingen till nämnda PCB pâverkas och kan anpassas till en önskad design.The embodiment shown in Fig. 5 is similar to that in Fig. 3 but shows the difference that the loop antenna 530 is located on one side of the PIFA element 20 opposite the feed and 518 m: v:; 6 ground portions 22, 23 of the PIFA. This gives the advantage that the connection to said PCB is affected and can be adapted to a desired design.
Den i fig. 6 visade utföringsformen liknar den i fig. 2 men uppvisar skillnaden att anslutningsdelarna hos dipolantennen 630 finns på en sida av PIFA-elementet 20 motstående PIFA:ns matnings- och jordningsdelar 22, 23. Detta ger fördelen att kopplingen till nämnda PCB påverkas och kan anpassas till en önskad design.The embodiment shown in Fig. 6 is similar to that in Fig. 2 but shows the difference that the connecting parts of the dipole antenna 630 are located on one side of the PIFA element 20 opposite the feed and ground parts 22, 23 of the PIFA. affected and can be adapted to a desired design.
För att minimera kopplingen mellan den obalanserade och den balanserade antennen är den obalanserade antennen företrädes- vis miniatyriserad. Genom att lasta den obalanserade antennen med ett högt dielektriskt material, såsom keramiskt material eller en blandning av keramiskt material och plast, ökas mini- miavståndet mellan den obalanserade och den balanserade antennen, varigenom kopplingen däremellan ytterligare minskas.To minimize the connection between the unbalanced and the balanced antenna, the unbalanced antenna is preferably miniaturized. By loading the unbalanced antenna with a high dielectric material, such as ceramic material or a mixture of ceramic material and plastic, the minimum distance between the unbalanced and the balanced antenna is increased, thereby further reducing the connection between them.
Föredragna utföringsformer av en antennanordning enligt uppfinningen har beskrivits. Fackmannen inom teknikområdet inser dock, att dessa kan varieras inom ramen för bifogade patentkrav utan att man avviker från uppfinningsidén. Även om en sändande och mottagande antenn har visats begränsas sålunda ej uppfinningsidén till detta. Som exempel skulle två mot- tagande antenner kunna tillhandahållas, varvid en är balan- serad och den andra är obalanserad. På detta sätt minimeras kopplingen mellan dessa. Vidare uppnås antenndiversitet. De olika antennerna skulle kunna arbeta för olika kommunikations- system, t.ex. Bluetooth, GSM och UMTS. De skulle också kunna arbeta i olika band, t.ex. GSM90O och GSMl800. Andra kombina- tioner skulle kunna åstadkomma, såsom de möjliga kombinatio- nerna: två sändande/mottagande antenner; en sändande/- mottagande antenn och en mottagande antenn; en sändande/- mottagande antenn och en sändande antenn; två mottagande antenner; tvâ sändande antenner; en sändande antenn och en 518'706 ?ïävm}i."kå.@¿ 7 mottagande antenn; varvid i varje kombination varje antenn skulle kunna vara balanserad eller obalanserad.Preferred embodiments of an antenna device according to the invention have been described. However, those skilled in the art will appreciate that these may be varied within the scope of the appended claims without departing from the spirit of the invention. Thus, although a transmitting and receiving antenna has been shown, the inventive idea is not limited thereto. As an example, two receiving antennas could be provided, one being balanced and the other unbalanced. In this way, the connection between these is minimized. Furthermore, antenna diversity is achieved. The different antennas could work for different communication systems, e.g. Bluetooth, GSM and UMTS. They could also work in different bands, e.g. GSM90O and GSM1800. Other combinations could be made, such as the possible combinations: two transmitting / receiving antennas; a transmitting / receiving antenna and a receiving antenna; a transmitting / receiving antenna and a transmitting antenna; two receiving antennas; two transmitting antennas; a transmitting antenna and a receiving antenna; in each combination each antenna could be balanced or unbalanced.
Specifika antennmönster har visats. Fackmannen inom teknik- området inser dock, att den obalanserande antennen ej nödvän- digtvis är en PIFA utan kan vara exempelvis en patch, modifie- rad PIFA, meander-PIFA eller slitsantenn.Specific antenna patterns have been shown. However, those skilled in the art will recognize that the unbalanced antenna is not necessarily a PIFA but may be, for example, a patch, modified PIFA, meander-PIFA, or slit antenna.
I figurerna har matningsanordningar 24, 34 visats, vilka kan tolkas som: en matningsanordning för en sändande antenn, en mottagaranordning för mottagandeantenn och en matnings-/mot- tagaranordning för en sändande/mottagande antenn.In the figures, feeding devices 24, 34 are shown, which can be interpreted as: a feeding device for a transmitting antenna, a receiving device for a receiving antenna and a feeding / receiving device for a transmitting / receiving antenna.
