Abstract
This plane array antenna for receiving satellite broadcasts is an optimal combination of the plane array antenna main body having a tilt angle, a converter connected with the antenna main body through the power supply portion, and the rotation mechanism for rotating the antenna main body within almost a horizontal plane for tracking the azimuthal angle direction. The plane array antenna main body has the power supply portion formed at the center of the rotation and the converter includes a dielectric substrate having a microstrip channel formed on the substrate and a casing accommodating the substrate. The converter is fixed downwardly of the antenna main body and supports the antenna main body. The power supply portion includes the power supply probe with an insulation covering, and has its front end portion inserted into a space formed with the antenna body, a central portion extending through the casing of the converter, and the lowest end portion combined with the microstrip channel. The rotation mechanism includes a cylindrical body projecting downwardly from the bottom surface of the antenna main body at the outside of the converter and a driving mechanism for rotating the cylindrical body.
