Optimization of Circularly Polarized Corner Truncated Patch with Matlab Antenna Toolbox

In this paper a new approach for the optimization of a double truncated corner microstrip square patch antenna is proposed by exploiting method-of-moments (MoM) calculator of Matlab Antenna Toolbox. A problem solution is iteratively updated according to the optimization criteria, i.e., find the minimum axial ratio (AR) at the target frequency within the impedance bandwidth S11≤-10 dB. An update mechanism for the optimization variable domains is implemented to refine the solution step-by-step. In the proposed example it is found that this approach converges to a feasible solution in few steps (less than an hour).
