To provide an inverse F type antenna which makes horizontal plane radial characteristics uniform without impairing characteristics that the inverse F type antenna has a low profile, and has a high antenna gain.

A pair of vertical radial elements 1, 2 which are connected to a feeding line and one short-circuit element 3 are set as one unit, and the respective elements are disposed radially in a horizontal direction at the center of a feeding point in this unit, thereby forming a multi-element. With such a structure, it is possible to form the multi-element in an arbitrary unit number, and horizontal plane radial characteristics are made uniform, and an antenna gain can be enhanced.
