Waveguide power divider, waveguide phase shifter, and polarized antenna using same

摘要

The present disclosure provides a polarized antenna including a waveguide power divider, a waveguide phase shifter and a radiating unit. The waveguide power divider is configured to have an input waveguide for receiving a transmission signal, and first and second output waveguides for distributing and outputting the transmission signal. The waveguide phase shifter is configured to receive two output signals outputted respectively from the first and second output waveguides of the waveguide power divider, to variably change a phase difference between the two input signals, and to output respective changed signals. The radiating unit is configured to receive the respective changed signals from the waveguide phase shifter, and to combine and radiate the respective changed signals as a radio signal.
