Description

Antenna assembly
Technical field
The invention belongs to communication technical field, relate to a kind of antenna assembly.
Background technology
Along with today of vehicles high speed developments such as car, ship, broadcast listening (FM/AM) and CD music can not satisfy the needs of the existing vehicles, and satellite navigation (GPS), vehicle mounted communication (GSM), car, the amusements such as (ETV) of boat-carrying TV and office system have been the configurations of high-grade vehicles indispensability.And the majority in the above-mentioned functions all needs antenna to receive/send signal, does not have antenna assembly also just can't realize corresponding function.
At present, the function singleness of traditional antenna, electronic equipment is more many, and needed antenna amount is just more many, and many strip antennas are installed is extremely inconvenience for the vehicles such as limited car, ship in the space; And the position that antenna is installed is also very important, is contained in the shielding that shelter in the vehicles can be subjected to the vehicles itself and be used for metallicity panel that the vehicles pack etc., influences the signal reception; Being installed in the outside can influence attractive in appearance again.
At 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 are 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; Antenna casing 101 bottoms are equipped with base plate 106.Radio broadcasting antenna amplifier antennafire 105, satellite navigation receiver 107, radio communication receiver 108, in-car TV receiver etc. can be housed on base plate 106.Because being the top edges along shark fin type antenna shell 101, the radio receiving antenna 102 in this shark fin type antenna arranges, this radio receiving antenna 102(Source Music (AM/FM) antenna that in the ridge line of antenna casing 101, arranges) must guarantee certain length, otherwise can't guarantee sufficient performance, so be difficult to miniaturization.
In order to solve the problem of antenna miniaturization, those skilled in the art propose a kind of improved antenna again, as shown in Figure 2, this improved antenna is an antenna substrate 200, the first half of this antenna substrate 200 forms first a tabular antenna pattern 201, and the Lower Half of this antenna substrate is formed with and TDTV(TEL) second antenna pattern 202 of wire of frequency band resonance.This first antenna pattern 201 is connected with an end of aerial coil 203, and the other end of aerial coil 203 is connected with the AM/FM lead-out terminal that output AM/FM receives signal.The supply terminals of second antenna pattern 202 and TDTV(TEL) TDTV(TEL that uses of signal) terminal is connected.In this improved antenna, first antenna pattern will guarantee that the AM performance must arrange sizable area, for example umbrella; Described second antenna pattern is arranged on the below of first antenna pattern, has no doubt realized the purpose of miniaturization, but while first antenna pattern will inevitably become the shelter of electric wave, and the signal receiving performance of second antenna pattern is descended.
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 installed in 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 is upright to be located on the antenna base 320 and to be accommodated in the described space; Described antenna conductor 331 is being wound on the winding unit 332 with the regulation distance between centers of tracks on the above-below direction.This antenna assembly has increased antenna length, has improved antenna performance, has realized the purpose of miniaturization.But if two or more antennas is installed, it need use the different special coil of winding pitch of both sides up and down, and there is certain degree of difficulty in such coil in actual manufacturing, and cost is also higher.
UNECE26(Europe EXTERNAL PROJECTION regulation) become international standard in fact, the height of shark fins antenna must be in 70mm.But, take in many antennas at 70mm in interior antenna casing, then electrical Interference takes place in antenna each other easily.Therefore, how to arrange and a kind ofly can receive a plurality of non-interfering antennas in limited space content,, antenna assembly that cost is low low in the manufacture view difficulty is present urgent problem again.
