Abstract
Provided is a wide band antenna having ultra-wide band and high performance at a low cost. An antenna element constituting a part of an opening cross section structure of a double cylinder ridge waveguide is spread on a plane. The antenna element has a ridge element portion (21) for adjusting antenna characteristic corresponding to a ridge portion and a radiation element portion (22) for electromagnetic wave radiation. Substantially at a leading end portion of the ridge element portion (21), a feeder terminal (24) is formed. Ground portions (23a and 23b) are maintained at a ground potential and the feeder terminal (24) is guided to an outside as a coplanar waveguide.
