Abstract
The invention relates to an integrable dual-band antenna. Said antenna consists of an essentially rectangular overall surface that is located over a ground surface. Said overall surface consists of an L-shaped PIFA antenna and a rectangular PIFA antenna for emitting two independent frequencies. The PIFA antennae have three or four connections, which are connected by lines to two contact points.
Description
The present invention relates to a kind of Integrable dual-band antenna.
In mobile communication equipment, the reason for design has special requirement to antenna.Particularly antenna should be integrated in enclosure, can't see from the outside.Antenna should be used for two different frequency ranges at least simultaneously, and low cost of manufacture.
Up to now, the antenna of most of mobile communication equipments is bar antennas, i.e. the antenna that can see from the outside.A kind of integrated form antenna for example is disclosed among the patent documentation WO 95/24745.But this known technology is very expensive, and the size of antenna is very big, so that can't find aerial position in existing equipment.
Task of the present invention is, a kind of antenna of the above-mentioned type is provided, and it does not have exposed parts, can be integrated in the communication terminal device shell, and have desired dual-band performance.
The solution of above task is, described antenna comprises that one is positioned on the ground plane and rectangular substantially general layout, for realizing the emission of two independent frequencies, described general layout is made up of a L shaped PIFA antenna and a rectangle PIFA antenna, and wherein said PIFA antenna has three or four lead-in wires that link to each other with two contacts through lead.
The present invention is to adopt a kind of antenna to the solution of the above problem, and it is made up of two PIFA (planar inverted F antenna) antenna structure of a space sealing, and it interconnects by special conductor structure.Can obtain a kind of small space structure by this structure, it is applicable to dual-band usage, and can be complementary with a shell that is made of non-flat surface or fillet flanging.This antenna uses near can being placed on inevitable metal flat especially, several millimeters of for example being separated by, and described metal flat constitutes the metal screen layer of electronic circuit usually.
The standard technology of employed punching press and bending plate is owing to having high speed of production, so its manufacturing cost is very low when making antenna.The cost of making the antenna contact spring in addition also can save, and this spring is used for setting up contact between the electronic circuit of antenna and equipment, because antenna springs can be made in a production technology as the integration section of antenna.
Pass through design optimization, antenna near being used for first resonance frequency of target band (for example GSM), it is used, and near second resonance frequency, can in broadband range, work, thereby can use in another frequency band (for example PCN or PCS).Can realize simultaneously that in addition nominal impedance is about 50 ohm, so antenna need not matching network or only gets final product work with a small amount of matching element.The effect of this scheme is can avoid always present loss in match circuit.
Creativeness of the present invention is, the inevitable coupling of two sub regions is taken in such a way, makes whole system to work in a plurality of frequency bands.Adopted a kind of special feeder, it has constituted 3 or 4 contacts on two contact points on the surface of emission for this reason.
The explanation of a dependent claims and a following embodiment about antenna of the present invention is seen in the favourable improvement of other of antenna of the present invention.
The present invention is further illustrated for contrast accompanying drawing illustrated embodiment below.
Fig. 1 represents the schematic diagram of one first embodiment of the present invention,
Fig. 2 represents of the present invention one second schematic diagram of executing example,
Fig. 3 to Fig. 5 represents the stereogram of the specific embodiment of antenna of the present invention.
In embodiment illustrated in figures 1 and 2, the minor structure S1 shown in two links to each other with P2 with defined wiring position P1 by lead L1 respectively with S2.Wherein said minor structure S1 constitutes L shaped shape basically, and minor structure S2 constitutes rectangle basically.
Also have two other wiring position P3 and P4 to interconnect in addition by one second lead L2.
On two fixing positions, on this lead, can realize two contact K1 and K2.
Therefore resulting antenna is to be made of two subregions in parallel with a bipolar wiring contact.
Described antenna is made up of two different planar structures or inserted sheet.L shaped inserted sheet wherein operates mainly in the GSM frequency band, and approximate rectangular inserted sheet operates mainly in the PCN frequency band.Therefore whole system can be connected by the lead of two inserted sheets in two or more frequency bands and work.
Two antenna inserted sheet S1 and S2 interconnect by lead L1 and L2.Lead L1 also can constitute by a short and wide bonding jumper, and as the part (referring to Fig. 2) of inserted sheet.
Wiring position P1 and P2 are usually located on the diagonal of two inserted sheet S1 and S2.Basically determined the input impedance of antenna between wiring position P4 and the P1 in the distance on the inserted sheet S1 and wiring position P2 and the distance of P3 on inserted sheet S2.
K1 and K2 are by the input impedance of antenna and mainly are to determine by the layout of wiring board.A contact links to each other with the ground wire of wiring board, and another contact links to each other with the reflector of the electronic circuit of mobile communication equipment and the input of receiver.
Electronic circuit by mobile communication equipment can define impedance (typical impedance is 50 ohm).According to calculating the location that to select wiring position P3 and P4, make the impedance of electronic circuit and antenna mate mutually.
Fig. 3 to Fig. 5 represents specific embodiments of the invention, and it for example can be installed in the mobile communication equipment.
