Array antenna device and radio equipment

摘要

A dielectric line (21) is composed of a conductor plate (31) and dielectric strip on the side of a fixed portion and a dielectric line (22) is composed of a conductor plate (32) and dielectric strip on the side of a moving portion. A directional coupler is composed of the dielectric lines (21, 22). On a dielectric plate (13) of an array antenna portion a plurality of linear array antennas are formed and connected to a microstrip (3) as a feed portion. By displacement of the moving portion the feed point to the feed portion is changed and the feed phase to each linear array antenna and the feed power to each element antenna are changed. Thus, the direction of a beam is changed.
