COMMUNICATION DEVICE AND FEEDER DEVICE
First Claim
1. A communication device comprising:
- an antenna that generates a magnetic field and communicates with an external device that generates a magnetic field during communication;
at least one magnetic field sensor that includes a pair of sensor elements, the at least one magnetic field sensor detecting magnetic field strength by receiving the magnetic field of the antenna and the magnetic field of the external device;
a communication component that communicates with the external device via the antenna; and
a controller that processes output signal indicative of the magnetic field strength detected by the at least one magnetic field sensor, a component of the magnetic field of the antenna in the output signal being suppressed.

Abstract
A communication device includes an antenna, at least one magnetic field sensor, a communication component, and a controller. The antenna generates a magnetic field and communicates with an external device that generates a magnetic field during communication. The at least one magnetic field sensor includes a pair of sensor elements. The at least one magnetic field sensor detects magnetic field strength by receiving the magnetic field of the antenna and the magnetic field of the external device. The communication component communicates with the external device via the antenna. The controller processes output signal indicative of the magnetic field strength detected by the at least one magnetic field sensor. A component of the magnetic field of the antenna in the output signal is suppressed.
