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 execution mode, 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 execution mode, 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.By the antenna integrated amplifier of GPS/BDS, according to the car antenna of embodiment of the present invention, can realize the compatibility to GPS and BDS equipment, adopt single module can make full use of the limited volumetric spaces of antenna.
In execution mode, the radio communication oscillator 6 with sleeve loading structure for example, connects with the interior Wireless Telecom Equipment (, 3G equipment, GPRS equipment etc.) of car.Sleeve loading structure can make radio communication oscillator 6 realize high-gain and broadband with little volume, below will be elaborated to this.
