摘　　要：介绍了Rotman透镜的工作原理,给出了透镜的设计方程。为适应天线在高功率水平下工作的需求,使用平板型设计,以提升功率容量,采用宽度渐变的方式改善了Rotman透镜的传输线分布方式。设计了一款工作在9.4GHz、拥有9个输入端口和9个输出端口的高功率容量Rotman透镜天线。仿真结果表明,天线的扫描角度可以达到±22°,各方向增益大于16.5dBi,效率约为60%,功率容量可达到0.9GW。The principle of Rotman lens antenna is introduced, and thedesign equation of lcns is given. In order to meet the needs of the antenna at high power levels, a flat type design is adopted to increase the power capacity. The high power capacity Rotman lens antenna works at 9.4 OHz, with nine input ports and another nine outpult ports. The simulation results show that the scanning angle of the antenna can reach ±22°, the gain is more than 16.5 dBi, the efficiency is about 60% , and the power ca pacity of antenna is 0. 90W.
