Abstract
An antenna including a rectangular ground plane, a feed point disposed in a vicinity of a corner of the ground plane, an antenna element coupled to the feed point, and a parasitic element coupled to the ground plane. In this antenna, the shortest length from the feed point to a distant narrow side of the ground plane and a shortest length from the feed point to a tip of the parasitic element via the ground plane have substantially the same electrical length. Such a configuration can correspond to a small and thin size and reduce SAR easily.
