摘要
A design method of a new shaped spherical reflector antenna with a horn feed for wide-angle scanning is presented,in which the horn's phase center need not be found out and its optimal position can be determined.It is found from numerical calculation that the shaped spherical reflector antenna has better electrical performance than that of the spherical reflector antenna,at the maximum gain value under the conditions of the same feed and reflector aperture,and can be used as a wide angle searching antenna.
