摘要
双弯曲反射面天线是一种经典的赋形反射面天线。本文对其偏焦和宽频带性能进行了研究。采用优化设计的方法,实现15％带宽、偏焦7.5°(6.25倍波束宽度)的偏焦波束.并在此基础上实现了天线的三波束工作。
Dual-bend reflector antenna is a classical beam-shaped antenna. Its performances in offset and broad band are studied in this paper. Using optimization design, bandwidth of 15% and offset of 7. 5°(6. 25 times beam width) are realized. Based on the study,tri-beam operation of the antenna is implemented .
