Abstract
Based on the design philosophy of overseas scholars about multi-focus parabolic reflective surface,in allusion to the known feed source locations in multi-beam antenna design,a design method of improved multi-focus parabolic reflective sur-face is proposed. The five-focal parabolic antenna with the feed source located at ±270 mm,±150 mm,0 mm was designed by means of the method to shape the reflective surface. The gain difference between the edge beam and central beam is reduced by 0.2 dBi and 0.7 6dBi by optimizing the weighting coefficient of the fundamental paraboloid,which makes the gain of each beam in the coverage area average,and meets the requirements of the low side lobe.关键词
