Abstract: PROBLEM TO BE SOLVED: To easily control the beam width of a horizontal plane in a simple and compact structure at a low cost about a polarization sharing antenna fitting a base station antenna for mobile communication, etc., where antenna directivity change corresponding to a service area, beam width change in particular is required. SOLUTION: At least two radiating elements (patch) installed on a bottom board are respectively energized through a probe, a slot, etc., and vertical polarization and horizontal polarization are attained. The bottom board is printed on a dielectric substrate, and a power feeder circuit for each polarization energization can independently be formed on the rear surface. The bottom board shapes of the both sides of a slot for horizontal polarization are also deformed into a projection type or a T-type so as to be able to obtain matching to a feed line. The angle of directivity in a horizontal plane can be made narrow by using these two sets. A beam width can be controlled by an element interval, and even beam width change due to diffraction of the edge of a reflector can be compensated by adequately adjusting the element interval.
