To provide an antenna device that reduces change of a gain by a human body.
An antenna device includes: a magnetic flow antenna 401 using a magnetic flow as a radiation source; a current antenna 402 using current as a radiation source; and a current magnetic flow distribution control circuit 403 which supplies signals to the magnetic flow antenna 401 and the current antenna 402. The magnetic flow antenna 401 and the current antenna 402 are arranged so that a polarized wave emitted from the magnetic flow antenna 401 and a polarized wave emitted from the current antenna intersect orthogonally. The current magnetic flow distribution control circuit 403 controls distribution of radio waves emitted from the magnetic flow antenna 401 and the current antenna 402.
