ABSTRACT:
In an electronic apparatus which is equipped with a first transmission unit for performing a first communication by an electromagnetic wave; a second transmission unit for performing a second communication by an electromagnetic wave; and a reception unit for receiving a signal transmitted from the second transmission unit, the electronic apparatus is comprised of an antenna arranged by a radiator having a size which is smaller than 1/(2π) of a wavelength of a use electromagnetic wave, which is connected to at least the second transmission unit and the reception unit.
