发明名称 Ground station antenna for satellite communication systems
摘要 A ground station for satellite communication transmission systems which utilize a beam which is relatively narrow in the "hour angle direction" and is relatively wide in the "declination angle direction" so as to prevent interference from satellites on geostationary orbits and resulting in an antenna which is longer in the longitudinal direction than it is in the transverse direction, thus, making it easy to move from place to place without disassembly.
