PROBLEM TO BE SOLVED: To provide an apparatus and method for time-division duplexing transmission/reception, utilizing a polarized duplexer. SOLUTION: The time-division duplexing transmission/reception apparatus comprises a transmitter which generates a transmission signal, an antenna which transmits the generated transmission signal to an external device and receives a received reception signal from an external device, a receiver which restores source data by demodulating the reception signal, and a polarized duplexer which has a first end connected to the transmitter and the receiver and a second end connected to the antenna and comprises an inclined surface, which polarizes the transmission signal and the reception signal, such that the directivity of the transmission signal generated by the transmitter and the directivity of the reception signal received from the antenna and input to the receiver are mutually orthogonal.
