Has the directivity variable antenna the satellite communications earth station

摘要

PURPOSE: To attain communication with plural satellites by simple constitution by providing a moving means with a control means for indicating a moving variable. ;CONSTITUTION: In the cross section of a satellite 23 for communicating a main beam 25 from an antenna part on an orbit 24, its vertical width is longer than its horizontal width. The moving means moves the main beam to an azimuth direction. A control means indicates a moving variable ϕ to the moving means.;COPYRIGHT: (C)1996,JPO
