PROBLEM TO BE SOLVED: To provide a radio communication device having a new configuration capable of removing a wraparound wave and a reflection wave from a reception signal.SOLUTION: The radio communication device comprises an antenna 10, a transmission unit 4, a reception unit 6, a circulator 8, and a phase adjustment unit 20 which is connected between the circulator 8 and the antenna 10 for changing a phase of a signal to be input. When a transmission signal is input from the transmission unit 4 to the antenna 10 through the circulator 8, a reflection wave 40 of the transmission signal is input from the antenna 10 to the circulator 8 through the phase adjustment unit 20. When a transmission signal is input from the transmission unit 4 to the circulator 8, a wraparound wave of the transmission signal is input to the reception unit 6. The phase adjustment unit 20 changes a phase of the reflection wave 40 which is input from the antenna 10 so as to be an inverse phase of a phase of the wraparound wave 30. |
