Abstract

The invention relates to a GPS (global positioning system) antenna for a vehicle. The GPS antenna comprises a ceramic antenna assembly and a PCB, wherein the ceramic antenna assembly is combined and mounted on the PCB; the PCB comprises a double-power-supply processing circuit, a resistor, a prime amplifier, a filter, a power divider, a post-amplifier A and a post-amplifier B; the double-power-supply processing circuit is connected with the resistor; the resistor is connected with the prime amplifier, the post-amplifier A and the post-amplifier B; the ceramic antenna assembly is connected with the prime amplifier which is connected with the filter; the filter is connected with the power divider; the divider is connected with the post-amplifier A and the post-amplifier B; the post-amplifier A is connected with the double-power-supply processing circuit and a signal receiving end of a traveling data recorder; the post-amplifier B is connected with the double-power-supply processing circuit and a signal receiving end of a vehicle-mounted entertainment system. With the adoption of the GPS antenna for the vehicle, interior space is saved, design and layout of the whole vehicle are facilitated, assembly procedures are simplified, the number of parts is reduced, and manufacturing cost and weight of the whole vehicle are reduced.

Description

technical field [0001] The invention relates to the field of automotive antennas, in particular to a GPS antenna for vehicles. Background technique [0002] With the regulations on the application of driving recorders on heavy trucks and the improvement of vehicle entertainment system functions, in order to meet the needs of users for information transmission, positioning and navigation, the current heavy truck antennas often need to be equipped with two GPS antennas, respectively for the driving recorder. Provide GPS signal independently with car entertainment system. Vehicle antennas are usually installed in the center console, under the front windshield, in front or behind the roof cover, and different manufacturers choose different fixing methods according to different needs. This will result in a large footprint, high unit cost of components, high manufacturing and design costs and other shortcomings. Contents of the invention [0003] The object of the present inve...
