  • The machining quality of reflector antenna panels includes machining accuracy and surface quality, both of them will effect electrical performance of the antenna. For the surface quality which is studied less, surface texture is modeled by fractal function. Microscopic surface texture is introduced in the formula of antennas far field patterns by phase difference. Gaussian integral formula in triangular element is used in numerical solution of the formula. By simulation experiment, the effects of different amplitude, density and roughness of the antenna panels surface texture on antennas far field patterns is studied. Research shows that with the increase of amplitude, the far field pattern changes more; with the increase of density and roughness, the far field pattern change less. And the effect degree of amplitude is the first, the density is the second, the roughness is the least. A new way of studing the effects of surface texture on far field patterns of the reflector antenna is proposed, and the conclusion can be referenced in practice.
