Abstract
A radio communication apparatus includes a first antenna, a second antenna, a third antenna, and a processor that varies a phase difference between a first signal transmitted from the first antenna and a second signal transmitted from the second antenna, measures a received power pattern of a synthesized signal of the first signal and the second signal that is received by the third antenna, and adjusts a phase shift of a signal that is transmitted from the first antenna or the second antenna, based on a difference between the measured received power pattern and a received power pattern obtained by calculation.
