Multibeam antenna for receiving satellite

摘要

A cheap and easily installable multibeam antenna is provided for receiving the waves simultaneously from plural numbers of communication satellites and from a broadcast satellite, which have different stationary orbits over the equator . An offset parabolic face is employed as a reflector of the antenna and a converter with a primary radiator for receiving communication satellite is set at the focus point of the offset parabolic face, and a converter with a primary radiator for receiving a broadcast satellite is set near the envelope of the reflected wave at the offset parabolic face, and the antenna, which is directed to the communication satellite, is installed so that the plane of symmetry of the offset parabolic face is coincide with the plane specified by the communication satellite, the broadcast satellite and the receiving point.
