A wireless communication apparatus includes: a first antenna; a second antenna; a variable phase shifting unit that changes a phase of a high frequency signal to be received or transmitted via the first antenna and the second antenna; and a phase-information table storage unit that stores a phase information table in which phase information is associated with each of a plurality of communication terminals as communication partners. When communicating with one communication terminal out of the plurality of communication terminals via the first antenna and the second antenna, the variable phase shifting unit changes a phase of a high frequency signal on the basis of phase information stored in the phase information table in association with the one communication terminal.
