This work presents a performance analysis of probe-fed circularly-polarized moderately-thick microstrip patch antennas. Five typical geometries are designed according to the null reactance condition. A nonlinear regression, based on HFSS simulations, is implemented in order to identify the most robust geometry, regard­ing the manufacturing process. The analysis focus is on broadside axial ratio degradation and frequency deviation parameters. Experi­mental results validate the proposed approach and the nonlinear regression calculations.
