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.
