A wireless communication apparatus includes multiple antenna devices, a signal generator, a phase shifter, a phase controller, and a quadrature error corrector (phase error corrector and amplitude error corrector). The signal generating circuitry, in operation, generates an IQ signal having an I signal and a Q signal. The plurality of phase shifting circuitry provided for each of the plurality of antenna devices, in operation, generates a plurality of combination signals by combining the I signal and the Q signal based on a predetermined combining scheme. The phase controlling circuitry, in operation, controls the predetermined combining scheme in each of the plurality of phase shifting circuitry. The quadrature error correcting circuitry, in operation, corrects at least one of amplitude combining scheme and phase combining scheme of the predetermined combining scheme in a correction of the predetermined combining scheme.
