1. An antenna device comprising:
a mobile terminal antenna that receives a radio wave output by a reader/writer provided in a mobile terminal;
a plurality of IC card antennas that communicates with an IC card including an IC chip for the IC card that reads/writes data in a contactless manner in response to a command transmitted by the reader/writer; and
a control circuit that operates by using power generated when the mobile terminal antenna receives the radio wave output by the reader/writer and controls enabling or disabling of each IC card antenna of the plurality of IC card antennas in response to the command transmitted by the reader/writer,
wherein the control circuit includes
a switch that is connected to each IC card antenna of the plurality of IC card antennas and switches enabling or disabling of the plurality of IC card antennas,
a controller that controls the switch, and
an internal IC chip that controls operation of the controller in response to the command and reads/writes data in a contactless manner in response to the command.
