Abstract
To provide an antenna device capable of diminishing gain changes caused by a human body. An antenna device has a magnetic current antennathat takes a magnetic current as a source of emission; an electric current antennathat takes an electric current as a source of emission; and an electric current/magnetic current distribution control circuitthat feeds signals to the magnetic current antennaand the electric current antenna, wherein the magnetic current antennaand the electric current antennaare arranged in such a way that a polarized wave emitted from the magnetic current antennaand a polarized wave emitted from the electric current antennacross each other at right angles. The electric current/magnetic current distribution control circuitcontrols distribution of a radio wave emitted from the magnetic current antennaand a radio wave emitted from the electric current antenna
