By technique scheme, the car antenna providing, has FM reception, satellite fix and wireless network concatenation ability, adopts the radio communication oscillator of sleeve antenna loading structure, has realized high-gain and broadband, can be applicable to plurality of wireless networks standard.
In embodiment, radio oscillator 3 can be AM/FM pick-up dipole, and for example, it can be sent to amplifier circuit module 4 by the radio signal receiving, and the latter can deliver to vehicle-mounted radio equipment to play after signal is amplified.
In embodiment, satellite antenna amplifier 5 can be the antenna integrated amplifier of GPS/BDS. As an example, the antenna integrated amplifier of GPS/BDS can adopt the GPS/BDS bimodulus receiver module of the MT-5631B model of Taiwan ring day (Globalsat) company.

Sleeve loading structure can make radio communication oscillator 6 realize high-gain and broadband with little volume, below will be elaborated to this.
Fig. 2 is the radio communication oscillator structure schematic diagram according to one embodiment of the present invention. As shown in Figure 2, can comprise according to the radio communication oscillator 6 of embodiment of the present invention: inner sleeve 61, outer sleeve 62 and with slide glass 63, wherein one end of inner sleeve 61 for example can connect, with slide glass 63 surfaces the geometric center of slide glass 63 (with), and the other end of inner sleeve 61 can be fixed on mounting base 2 and connect in-vehicle wireless communications device; And outer sleeve 62 can be fixed on mounting base 2 and with mounting base 2 altogether, this outer sleeve 62 is placed on inner sleeve 61 away from the one end with slide glass 63 and does not contact with inner sleeve 61.
As shown in Figure 2, in embodiment, outer sleeve 62 can be coaxial with inner sleeve 61, forms the cylinder monopole antenna structure with axial symmetry. In a preferred embodiment, the length of inner sleeve 61 is greater than the length of outer sleeve 62, starts outside emittance to meet electromagnetic wave propagation characteristic from the upper end open of outer sleeve 62.
By technique scheme, can increase the equivalent length of antenna by tube-in-tube structure, thereby effectively shorten the length of radio communication oscillator, can be placed in antenna casing. And utilize with slide glass, can not reduce under the prerequisite of gain and improve the standing-wave ratio characteristic of antenna in working band. The radio communication oscillator that embodiment of the present invention provides, by inner sleeve, outer sleeve and the combination configuration with slide glass, has been realized high-gain and broadband, can be applicable to 3G communication backward compatible GPRS simultaneously.
The antenna of tube-in-tube structure utilizes antenna slenderness ratio principle, can fall low-impedance rate of change, improves the beamwidth of antenna. Specifically, according to the slenderness ratio principle of antenna, the severe degree that the input impedance of element antenna changes with electrical length depends primarily on the characteristic impedance of antenna. Characteristic impedance is larger, and input impedance is just fiercer with the variation of electrical length, and the impedance bandwidth of antenna is just narrower; Otherwise characteristic impedance is less, the impedance bandwidth of antenna is just wider. Thick oscillator has lower characteristic impedance, and asymmetric version can play the staggered tuning effect in similar circuit, thus broadening impedance bandwidth effectively. An overstriking oscillator is also realized the straightforward procedure of asymmetric feed, is to add a coaxial metal sleeve with it in antenna radiator outside, forms sleeve antenna. From intuitively, metal sleeve is equivalent to a thick oscillator, and its special feeding classification (coaxial feeding) in addition, makes the impedance operator of the antenna of this structure be better than significantly common element antenna. The relative bandwidth of general sleeve antenna at least can reach one more than octave.
In coaxial feeding mode, the inner wire of coaxial line connects the inner sleeve 61 as radiant body, and coaxial outer conductor connects outer sleeve 62, and its outer wall electric current and inner wire electric current are equidirectional, are also equivalent to form a part for radiant body, and double as sleeve. The inwall electric current of the electric current of inner sleeve 61 and outer sleeve 62 is anti-phase, has played the effect of transmission line, and the outer wall electric current of outer sleeve 62 and the electric current of inner sleeve 61 are equidirectional, has also formed a part for radiant body. The mechanical strength that has not only improved antenna of this structure, and due to oscillator overstriking, significantly improved the impedance operator of antenna, effectively broadening the working band of antenna.
Although and the antenna of tube-in-tube structure has money working band, but there will be input impedance to reduce in the time that frequency increases to a certain degree, the problem that voltage standing wave ratio increases, is difficult to meet instructions for use. Therefore, the present invention increases with slide glass 63 on the basis of tube-in-tube structure, reduces voltage standing wave ratio improving the standing-wave ratio characteristic of antenna in working band under the prerequisite that does not reduce gain in large frequency range. Therefore, the radio communication oscillator providing according to embodiment of the present invention has wider working band can communicate by letter with GPRS for 3G, and can obtain good signal quality.
