AI Technical Summary

Problems solved by technology

However, in practical applications, each switched off unit 13 will often generate parasitic capacitance
In addition, since each closed switching unit 13 is connected in parallel, a large parasitic capacitance will be generated, which will cause insertion loss in the antenna switching device 10 and cause energy loss of the transmitted or received radio frequency signal.

Abstract

The invention discloses an apparatus for switching an antenna with reduced signal losses. The apparatus herein comprises a plurality of switching modules, each switching module having one end connected to an antenna unit and another end connected to a receiving end. Each switching module includes a plurality of switching units which are in serial connection, wherein at least one switching unit on each switching module has a width smaller than the other switching units. In this way, the apparatus herein can reduce stray capacitance produced by a closed switching module and improve the voltage standing wave ratio of the apparatus.

Description

technical field [0001] The invention relates to an antenna switching device capable of reducing signal loss, which can be used to reduce parasitic capacitance generated by a switched off module. Background technique [0002] see figure 1 , is a schematic diagram of the structure of the existing antenna switching device. As shown in the figure, the antenna switching device 10 mainly includes an antenna unit 11 and a plurality of switching units 13, wherein one end of each switching unit 13 is connected to the antenna unit 11, and the other end of each switching unit 13 is respectively connected to different transceivers 15 , and the connection relationship between the antenna unit 11 and each transceiving path 15 can be switched through the switching unit 13 . [0003] In practical applications, one of the switch units 13 is usually turned on (on), and the other switch units 13 are turned off (off), so that the antenna unit 11 is electrically connected to one of the transce...
