Antenna oscillator amplifier board and vehicle-mounted antenna system

Abstract

The invention provides an antenna oscillator amplifier board and a vehicle-mounted antenna system. The antenna oscillator amplifier board comprises an antenna oscillator. The antenna oscillator is composed of two PCBs (printed circuit boards) connected by a transition support, and each PCB is divided into an upper part, a middle part and a lower part. Each upper part of the PCB board is coated with copper on both sides, folded lines are distributed on the middle part, and the folded lines on the PCBs are connected through the transition support; and an amplifier is arranged on the lower part of one PCB, and is connected with the antenna oscillator. According to the arrangement of the antenna oscillator amplifier board, the amplifier is arranged on the lower part of the PCB which constitutes the antenna oscillator, so that size of the antenna oscillator amplifier board is greatly reduced; the antenna oscillator can be accommodated in a shell shaped like a shark' fin and looks more attractive, and wind resistance is reduced; a satellite navigation antenna module, a mobile communication antenna module and a terrestrial television antenna module and the like or optional combinations thereof can be arranged in the shell shaped like the shark's fin, so that the vehicle-mounted antenna system has multi-band and multipurpose receiving functions.

Description

technical field [0001] The invention relates to a car antenna, in particular to an antenna vibrator amplifier board and a car antenna system. Background technique [0002] At present, the vehicle-mounted antennas used to receive AM / FM radio broadcasts generally use a monopole λ / 4 wavelength to design a certain length of metal rod-shaped antenna vibrator, which is relatively long. Restricted by the national standard GB-11566-2009 regulations, this vehicle-mounted antenna is designed as a separate structure, consisting of an antenna vibrator and a mounting base. The antenna vibrator and the mounting base are combined through a threaded connection, and the antenna vibrator is easy to lose, causing the overall antenna to be damaged. invalidated. Antenna vibrators that are too long and too high also increase the wind resistance during driving and are easy to break. [0003] Later, a shark-fin vehicle antenna with a relatively low height and a beautiful appearance appeared, and ...
