<p>Provided is an antenna device (1) including: an antenna element (120); a substrate (100) on which a ground conductor is provided; a first feeding portion (130); a second feeding portion (140); and a switching section (111, 131, 141). A direction in which high frequency electric current mainly flows in the ground conductor is different from while the first feeding portion (130) feeds the antenna element (120) to while the second feeding portion (140) feeds the antenna element (120).</p> |
