A new phase efficiency calculation model for optimization of ahat‐fedreflector antenna with arbitrary radius of ring‐shaped phase center

Abstract: A hat-fed reflector antenna with large radius of ring-shaped phase center (RSPC) is reported in this article. First, a new phase efficiency calculation model (PECM) based on new phase reference point is presented, which can accurately calculate the phase efficiency of a hat-fed with arbitrary radius of RSPC. Second, based on the invented PECM, the hat-fed can be optimized by using cosimulation method of HFSS and MATLAB, high aperture efficiencies are achieved in the whole band. To prove the validity of the new… Show more
