| Abstract: | Firstly, the important relation formula for the points of parabolic torus reflector and subreflector is obtained by using the equivalent ray path condition. Secondly, the formula of radiation pattern for multiple-beam parabolic torus reflector antenna with phase-correcting subreflector is given by using the law of microwave optics intension, geometrical optics method and physical optics method skillfully; Finally, an antenna has been calculated with the radiation pattern formulas in this paper, and the result of calculation is considerably consistent with the result of experiment. |
