【摘要】 分析了带交叉接头的双模馈源，分析和计算了收、发状态下偏置反射面天线的辐射场和焦区场，讨论了馈源位置误差，设计和测试了高效偏置反射面天线．实测结果与预计结果一致，达到预期的高效率．该天线适用于卫星电视接收站．更多还原

【Abstract】 Coaxial feed with bifurcation is analyzed The radiation field and focus field of an offset reflector are analyzed and calculated both for the transmitting and receiving modes The position tolerance of feed is discussed efficiency offset reflector antenna is designed and tested. Experimental results coincide well with theoretical results.Higher efficiency of use in reflector is obtained as has been. expected It is suitable for TVTOs.更多还原
