Patent Images
1. A slot antenna, comprising:
- an antenna element having an aperture type slot;
a reflector disposed by being opposed to the antenna element;
a feeding device which is electrically and physically connected to the antenna element and the reflector;
a short-circuiting device which electrically short-circuits the antenna element and the reflector; and
a reducing device which reduces a reactance component of the antenna.

Abstract
To make an antenna wideband under thin state. The slot antenna includes an antenna element having an aperture type slot, a reflector disposed by opposing to the antenna element, a feeding device which is electrically and physically connected to the antenna element and the reflector, a short-circuiting device which electrically short-circuits the antenna element and the reflector, and a reducing device which reduces the reactance component of the antenna. Since the reducing device for reducing the reactance component of the antenna is provided, the reactance component of the antenna can be reduced even if the antenna is formed thin and the antenna can be made wideband regardless of its thinness.
