Vehicle mounted antenna

Abstract

The invention discloses a vehicle mounted antenna which comprises a housing, an installing base plate and a radio oscillator arranged outside the housing. The housing and the installing base are matched. The vehicle mounted antenna further comprises an amplifier circuit module, a satellite antenna amplifier and a wireless communication oscillator which are arranged on the installing base plate, wherein the amplifier circuit module is connected with the radio oscillator and outputs a radio signal received by the radio oscillator to an in-vehicle radio receiver device. The satellite antenna amplifier outputs a received satellite signal to an in-vehicle satellite positioning device. The wireless communication oscillator is provided with a sleeve loading structure, connected with an in-vehicle wireless communication device and used for transmitting / receiving a wireless communication signal wirelessly. By adopting the technical scheme, the vehicle mounted antenna has the capacities of frequency modulation receiving, satellite positioning and wireless network connection, achieves high gain and wide frequency band by adopting the wireless communication oscillator with the sleeve antenna loading structure and can be suitable for various wireless network types.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a vehicle-mounted antenna. Background technique [0002] With the development of the automobile industry and the popularization of automobiles, people's requirements for automobile comfort, safety, convenience and intelligence are increasing. In order to meet people's requirements for the use of vehicles, manufacturers have installed a variety of on-board equipment inside the vehicle (for example, AM / FM radio, global positioning system (GPS) navigation equipment, on-board TV, etc.), and installed receiving antennas outside the vehicle. [0003] In vehicle equipment, such as navigation equipment, the GPS system was generally used in the past. However, with the establishment of the Beidou System (BDS) with higher accuracy and lower price, more and more equipment will support it, which also Cause product differentiation in the market. For another example, vehicle-mounted wire...
