摘要：
The equations of the reflector contours and the radiation patterns of the shaped dual-reflector antenna have been derived, and the methods of designing the antenna are also introduced briefly. The calculated and measured results suggest that this new type of antenna has the advantages of low VSWR (voltage standing-wave ratio), low sidelobe, and high gain. Therefore it opens a bright prospect for the improvement of mid- and small-aperture antenna performance, and gives the possibility for the realization of the 1990s new standard specified by CCIR (International Radio Consultative Committee) on mid- and small-aperture antenna for satellite-communication earth stations.
