Title:
MULTI-FREQUENCY FUSION PHASE-SHIFTING FEED NETWORK AND BASE STATION ANTENNA
Document Type and Number:
WIPO Patent Application WO/2023/130690
Kind Code:
A1
Abstract:
The present application relates to the technical field of antennas, and provides a multi-frequency fusion phase-shifting feed network and a base station antenna. The multi-frequency fusion phase-shifting feed network comprises a plurality of phase-shifting assemblies, each phase-shifting assembly comprises a phase-shifting circuit board and a slider assembly rotatably connected to the phase-shifting circuit board, and a phase-shifting circuit is provided on each phase-shifting circuit board; the plurality of phase-shifting circuit boards are divided into a first phase-shifting circuit board and a second phase-shifting circuit board, a combination circuit is provided on the first phase-shifting circuit board, and phase-shifting output ports of the phase-shifting circuit on the first phase-shifting circuit board and the phase-shifting circuit on the second phase-shifting circuit board are respectively connected to combined input ports of the combination circuit. By means of the multi-frequency fusion phase-shifting feed network and the base station antenna provided by the present application, multi-frequency independent phase shifting and fusion output can be realized, a combiner does not need to be independently arranged, reduction of occupancy of an antenna space is facilitated, layout is simplified, and cable solder joints are reduced; the phase-shifting feed network has good phase change stability and good consistency, and is convenient to assemble.
