【Abstract】 In this paper,a simple method for calculating the far-field radiation pattern of reflector antenna is presented.Taking the field distribution function of circular Gaussian aperture as an example,the illumination efficiency and radiation patterns at different illumination levels are calculated,and the effects of illumination level on the illumination efficiency,the half-power beamwidth and the first side-lobe level of the reflector antenna are studied.It provides a reference for antenna engineers to optimize the design of reflector design.更多还原
