摘要： An approach for providing a multiple-beam antenna system for receiving and transmitting electromagnetic signals from a plurality of closely spaced satellites is disclosed. Dielectric inserts are selectively coupled to the feedhorn bodies to alter the radiation patterns according to dielectric constants of the dielectric inserts. A reflector produces multiple antenna beams based upon the altered radiation patterns of the feedhorn bodies. The antenna provides simultaneous transmissions to satellites that are spaced about 2° or less.

摘要： A method of pointing an antenna at a transmitter comprising the steps of: (a) varying the azimuth of the antenna dish a predetermined number of degrees in a first direction from a predetermined azimuth angle; (b) measuring a first signal strength of an incoming signal received by the antenna dish; (c) varying the azimuth of the antenna dish the same predetermined number of degrees in a second direction from the predetermined azimuth angle, where the second direction is opposite to the first direction; (d) measuring a second signal strength of the incoming signal received by the antenna dish; and (e) comparing the first signal strength to the second signal strength, and if the first signal strength substantially equals the second signal strength, the current predetermined azimuth angle represents the optimal angle of azimuth for the antenna dish. However, if the first signal strength does not substantially equal the second signal strength, the process further comprises the steps of: (f) adjusting the predetermined azimuth angle, and (g) repeating steps (a)–(e). The same process is then repeated for the elevation adjustment.
