Description
Technical field
The invention belongs to communication technical field, relate to a kind of antenna assembly.
Background technology
Along with today of the vehicles such as car, ship high speed development, broadcast listening (FM/AM) and CD music can not meet the needs of the existing vehicles, and the amusements such as satellite navigation (GPS), vehicle mounted communication (GSM), car, boat-carrying TV (ETV) and office system have been the configurations of high-grade vehicles indispensability.And the majority in above-mentioned functions all needs antenna to receive/send signal, do not have antenna assembly just cannot realize corresponding function yet.
At present, the function singleness of traditional antenna, electronic equipment is more, and required antenna amount is more, and it is extremely inconvenience that the vehicles such as car, ship of limited space are installed many strip antennas; And the position of astronomical cycle is also very important, the shelter be contained in the vehicles can be subject to the shielding of the vehicles itself and the metallicity panel etc. for vehicles packaging, affects Signal reception effect; Mounted externally can affect again attractive in appearance.
For the problems referred to above, those skilled in the art propose a kind of shark fin type antenna, as shown in Figure 1, this antenna comprises shark fin type antenna shell 101, antenna casing 101 inside upper part is provided with radio receiving antenna 102, and the signal output part 103 of radio receiving antenna 102 is connected by the signal input part of antenna Connection Element 104 with antenna amplifier antennafire 105; Base plate 106 is installed bottom antenna casing 101.Base plate 106 can be equipped with radio broadcasting antenna amplifier antennafire 105, satellite navigation receiver 107, telecommunication transceiver 108, in-car TV receiver etc.Because the radio receiving antenna 102 in this shark fin type antenna arranges along the top edge of shark fin type antenna shell 101, this radio receiving antenna 102(Source Music (AM/FM) antenna arranged in the ridge line of antenna casing 101) certain length must be ensured, otherwise sufficient performance cannot be ensured, so be difficult to miniaturized.
In order to solve the problem of antenna miniaturization, those skilled in the art propose again a kind of antenna of improvement, as shown in Figure 2, the antenna of this improvement is an antenna substrate 200, the first half of this antenna substrate 200 forms the first day line graph 201 of a tabular, and the Lower Half of this antenna substrate is formed and TDTV(TEL) second antenna pattern 202 of wire of band resonant.This first day line graph 201 is connected with one end of aerial coil 203, and the other end of aerial coil 203 is connected with the AM/FM lead-out terminal exporting AM/FM Received signal strength.The supply terminals of the second antenna pattern 202 and TDTV(TEL) signal with TDTV(TEL) terminal is connected.In the antenna of this improvement, first day line graph will ensure that AM performance must arrange sizable area, such as umbrella; Described second antenna pattern is arranged on the below of first day line graph, no doubt achieves miniaturized object, but first day line graph will inevitably become the shelter of electric wave simultaneously, and the signal receiving performance of the second antenna pattern is declined.
In addition, those skilled in the art also propose a kind of antenna assembly, and as shown in Figure 3, this antenna assembly comprises radome 310, antenna base 320 and antenna part 330; Radome 310 is arranged on antenna base 320 with watertight means; Antenna part 330 is accommodated in the space of radome 310 and antenna base 320 formation; Antenna part 330 comprises winding unit 332 and antenna conductor 331; Described winding unit 332 to be erected on antenna base 320 and to be accommodated in described space; Described antenna conductor 331 is wound on winding unit 332 with regulation distance between centers of tracks in the vertical direction.This antenna assembly adds antenna length, improves antenna performance, achieves miniaturized object.But if two or more antennas will are installed, it would need the special coil using the winding pitch of upper and lower both sides different, and such coil exists certain difficulty in actual manufacture, and cost is also higher.
UNECE26(Europe EXTERNAL PROJECTION regulation) in fact become international standard, the height of shark fins antenna must within 70mm.But receive many antennas in the antenna casing within 70mm, then easily there is electrical Interference each other in antenna.Therefore, how to arrange a kind of multiple non-interfering antenna of can receiving in limited space content, antenna assembly that cost is low low in manufacture view difficulty, is current urgent problem again.
