Abstract

Abstract

The principle of Rotman lens antenna is introduced, and the design equation of lens 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 GHz, with nine input ports and another nine output 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 capacity of antenna is 0.9 GW.
