Embodiment 1

[0047] Such as image 3 with Figure 4 As shown, embodiment 1 utilizes MAX2180A to amplify the input signal. The AM and FM signals enter the MAX2180A chip in two ways. The AM signal passes through the parallel resonant frequency selection circuit of L1, L2 and C6 to filter out the interference signals that are not in this frequency band, and enters the chip pin 3 through C3; the FM signal passes through C7 and L8. The series resonant frequency selection circuit filters out the interference signal and enters the chip pin 5 through C5. The input AM and FM signals can amplify the input small signals through the adjustment of the peripheral circuit of the related pins of the chip. The AM output signal passes through C14, and the FM output signal passes through C17, and the AM and FM output signals are connected by L7 and output together. .

[0048] Figure 4 Among them, the feed end 21 of the antenna element 2 is at least partially overlapped with the input end of the antenna ...

Abstract

The invention relates to the field of glass antennas, particularly provides a vehicle-mounted active glass antenna integrating an antenna amplifier and glass, and also provides a manufacturing of the vehicle-mounted active glass antenna. The vehicle-mounted active glass antenna comprises the glass, an antenna element and an antenna signal amplifier, wherein an antenna signal amplifying circuit is integrally printed on the surface of the glass, the input end of the antenna signal amplifying circuit is at least partially coincided with the feeding end of the antenna element, and an antenna signal amplifying element is welded on the antenna signal amplifying circuit. The vehicle-mounted active glass antenna has the advantages that by integrally printing the antenna signal amplifying circuit on the surface of the glass, the number of antenna parts is reduced, and the manufacturing cost is correspondingly reduced; the distance between the antenna signal amplifier and the antenna element is minimized, and the problem of instable signals is obviously reduced; the position is very firm, the poor contact with the antenna element is avoided, the receiving stability of communication signals is guaranteed, and the integral performance is improved.

Description

Technical field: [0001] The invention relates to the field of glass antennas, in particular to glass antennas for receiving AM / FM signals and other communication signals on vehicles, and specifically provides a true active glass antenna in which an antenna amplifier is integrated with glass, and also provides a true active glass antenna Source glass antenna fabrication method. Background technique: [0002] In order to receive AM / FM signals and other communication signals, an antenna is usually installed on the vehicle. In the past, the antenna on the vehicle was mostly a rod or whip antenna protruding from the vehicle body. Although this kind of rod or whip antenna has good performance in receiving communication signals, it has disadvantages such as high manufacturing cost, wind gap noise, easy damage and affecting the overall appearance. Therefore, with the further development of technology, Now the antenna has been gradually integrated into the vehicle structure. For exa...
