Zusammenfassung:The equation was derived from the transmission line gap aclive radialion admillance formula. Based on HFSS. ihe waveguide-slol anlenna array in the slol of the active radialion admillance was extracted, the side lobe was reduced by Taylor distribution amplitude weighting, and the overload lechnology was adopled for radiating slol and the feed nelwork for broadband anlenna matching. An 11 X 12 single-pulse anlenna array was designed. The optimized simulation results show that the designed antenna meels the guidance requiremenl of high gain and low side lobe, and ihe VSWR bandwidth of antenna 1.5 is about 2 limes of that of traditional design.
