AI Technical Summary
The phase shifters of existing liquid crystal phased array antennas are susceptible to interference from the housing and crosstalk, which affects their performance.
A phase shifter assembly is designed, employing a first housing and a second housing arranged opposite to each other. By defining a receiving cavity between the housing and the phase shifting unit, waveguide structures and reflection structures are set up to reduce housing interference and reduce crosstalk. The phase shifting unit array is supported by support columns to ensure effective transmission and radiation of microwave signals.
This effectively reduces the interference of the housing on the phase shifter, lowers crosstalk, and improves the radiation efficiency of microwave signals and the working performance of the phase shifter.
