Experimental study of ultra-wideband low sidelobe reflector antenna with shaped beam

An experimental study of an ultra-wideband low-sidelobe reflector antenna with shaped beam is presented in this paper. The results show that the antenna has excellent electric performance in S-band with bandwidth greater than 25%; the average of peak sidelobes in the horizontal plane and VSWR are less than -31 dB and 1.23 respectively. In the vertical plane the patterns have super-csc/sup 2/ /spl theta/ type.
