ANTENNA DEVICE

摘要

To provide an antenna device which can reduce change of a gain by a human body. The 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 (402) 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).
