摘要：
An antenna apparatus includes: an extension conductor connected to a first section of an outer perimeter of an antenna element and along an entire length of the first section; connecting conductors connecting the antenna element to a ground conductor between the extension conductor and feed points on the antenna element; and a slit extending from the extension conductor to the antenna element so as to intersect a portion between connecting points of the connecting conductors and to intersect a portion between the feed points on the antenna element. The slit has a short-circuited end on the extension conductor.
