Abstract
Official abstract text for this publication.
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 ).
