<p>PROBLEM TO BE SOLVED: To provide a wideband linear-polarization sharing transmission/reception separation antenna device capable of suppressing mutual coupling.SOLUTION: The antenna device includes: a polarization sharing ring antenna 3 as a reception antenna; a polarization sharing patch antenna 5, disposed upward of the polarization sharing ring antenna 3, as a transmission antenna; first feeding means 7H, 7V electromagnetically coupled with the polarization sharing ring antenna 3 to feed power for each polarization; and second feeding means 9H, 9V for feeding power to the polarization sharing patch antenna 5 for each polarization. As the first feeding means 7H, 7V, probes 7H, 7V disposed adjacent to the polarization sharing ring antenna 3 are used.</p> |
