Abstract
A waveguide unit includes an interface unit configured to receive a transmission radio wave f1TX1 output from a transmission/reception processing unit, and output a reception radio wave f1RX1 to the transmission/reception processing unit. Further, the waveguide unit includes a transmission wave input port, a transmission wave output port, a reception wave input port, and a reception wave output port. Further, the waveguide unit includes a reception band-pass filter configured to pass the reception radio wave f1RX1 of a multiplex reception radio wave input to the reception wave input port and output the reception radio wave f1RX1 toward the interface unit, and, on the other hand, reflect a reception radio wave f1RX2 and output the reception radio wave f1RX2 toward the reception wave output port.
