Beam waveguide transmission system has advantages of high power capacity and working without rotary joints, therefore it is suitable for applying in high-power microwave system. Beam waveguide transmission system is introduced briefly; an antenna based on beam waveguide transmission system is designed ; design of feed source and selection of reflectors are discussed; and optimization analyzing by using of QUAST module based on software GRASP is conducted. In order to verify reliability of GRASP computation further, simulation of two reflectors in front of beam waveguide antenna is conducted; and comparison between the simulation results and GRASP result shows that they are well coincident with each other.
