Communication apparatus and control method of communication apparatus

Abstract

A communication apparatus configured to communicate with a wireless tag, includes: a plurality of loop antennas, each of the antennas being configured to output a magnetic field corresponding to a transmission signal relating to the communication with the wireless tag to independently communicate with the wireless tag; a communication control unit configured to output the transmission signal to a communication-target loo? antenna among the plurality of loop antennas; and a control unit configured to control a non-target loop antenna different from the communication-target loop antenna to generate a magnetic field for negating a magnetic field leaking from the communication-target loop antenna.
