Abstract:
A proximity type antenna includes an antenna pattern for wirelessly communicating with an external communication device by magnetic coupling and a conductive plate arranged near the antenna pattern. The conductive plate has an aperture and a slit extending from the aperture to an end of the conductive plate and at least part of the aperture is arranged at a position of overlapping either the antenna pattern or the region surrounded by the inner periphery of the antenna pattern.
