Claim:
1. A wireless communication apparatus comprising: a plurality of antenna devices; signal generating circuitry which, in operation, generates an IQ signal having an I signal and a Q signal; a plurality of phase shifting circuitry, provided for each of the plurality of antenna devices, which, in operation, generates a plurality of combination signals by combining the I signal and the Q signal based on a combining scheme that includes rotate calculations for the IQ signal in a complex plane, phase controlling circuitry which, in operation, controls the combining scheme in each of the plurality of phase shifting circuitry by individually suppling the first through fourth control values to the phase shifting circuitry, quadrature error correcting circuitry which, in operation, corrects at least one of amplitude combining scheme and phase combining scheme of the combining scheme in correcting the combining scheme,
