WIPO Patent Application WO/2007/015583
Kind Code:
A1
Abstract:
It is possible to provide an ultra-wide band and high performance antenna 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 unit (21) for adjusting antenna characteristic corresponding to a ridge portion and a radial element unit (22) for electromagnetic wave radiation. Substantially at the tip end of the ridge element unit (21), a feed terminal (24) is formed. Ground units (23a, 23b) are maintained at the ground potential and the feed terminal (24) is introduced outside as a coplanar waveguide.
