Abstract:
A radio communication device for executing a communication on the basis of a frequency division duplex, has a first antenna, a second antenna, a first receiver for receiving a first radio frequency signal via the first antenna, a second receiver for receiving the first radio frequency signal via the second antenna, a transmitter for transmitting a second radio frequency signal via the second antenna, a power measuring unit for measuring a first power of a component of the second radio frequency signal in a received signal received via the first antenna, and a control unit for controlling a reactance between the first antenna and the second antenna so as to lower an amount of coupling between the first antenna and the second antenna on the basis of the measured first power.
