摘要
Abstract
The multiple-mode conic horn is a high-efficiency antenna which is widely used as the feed of reflectors. Phase centers of the dual-band multiple-mode conic horn at receive and transmit frequency are not superposed, so the ascertainment of its phase center and location in the reflector system has unneglected influence on the performance of the reflector system. The definition of the phase center of the antenna is proposed and the phase centers of the dual-band multiple-mode conic horn at receive and transmit frequency are calculated. Finally the optimal location of the feed in the offset reflector antenna is confirmed by the analysis and optimization.关键词
