The paper describes a structure and a design optimization procedure of a miniaturized circular polarization antenna with elliptical ground plane slots and feed line with stepped-impedance stubs. Constrained optimization of all antenna parameters is executed in order to explicitly reduce the antenna size while maintaining required impedance axial ratio bandwidth of 5 GHz to 7 GHz at the same time. The size of the optimized antenna is only 16.2 mm × 16.7 mm (footprint of 271 mm2). At the same time, the electrical and field properties of the structure are competitive for state-of-the-art designs as indicated by the comparison provided in the paper.
