US Patent 11333735 Wireless communication device and wireless communication system

A wireless communication device includes a transmission section configured to output a calibration signal transmitted from a calibration antenna, a reception section configured to have input of a received signal from an antenna and obtain a baseband signal from the received signal, a correction phase calculation circuit configured to calculate a correction phase for correcting the baseband signal according to a deviation between a reception phase calculated based on the baseband signal obtained when the antenna receives the calibration signal and an ideal phase associated with the antenna, and a storage section configured to store the ideal phase and the correction phase.
