Abstract
A cylindrical reflector having a through hole in conformity with the shape of an elemental portion is fitted to the elemental portion in a LAN antenna in which the elemental portion encloses a linear conductor therein and projects from a base table, and further, the reflector is turned to be set at a position at which the directivity is formed in a specific direction. A flat plate or a curved plate forming a reflecting surface of the reflector is arbitrarily set, thus forming a desired radiation pattern of a beam.
