Fast-Shaping of Reflector Antenna Illuminated by Quasi-Actual Feed
A time-saving method to reshape the surface of reflector antenna fed by a quasi-actual feed(QAF)based on the Non-Uniform Rational B-Spline Surface(NURBS)technique,ray tracing technology(RT),physical optical method(PO),and Gauss-Legendre integral(GLI),is proposed.The optimized surface of the reflector can be smooth and timesaving by NURBS algorithm to support its better agreement with its future manufactured counterpart and by RT-PO-GLI method,where the antenna is fed by a QAF derived from the far-field data of an antenna model simulated from the commercial software MWS Studio CST,not a pure imaginary feed like in the available literature.An objective function is constructed with the weights of main-lobe level,side-lobe level,and beam width of the considered antenna to regulate the method to optimize electric far-field radiation patterns to specific purpose.The results show that the method has a faster calculating speed and can surely be expected to design a reshaped reflector antenna effectively and fast.
