Synthesis of circularly-polarized parasitic micro-array using spherical wave expansion

Résumé

This paper presents the design of a Right-Hand Circularly Polarized (RHCP) electrically small micro-array. The design principle is composed of a highly coupled three-IFA radiators distributed over a radial configuration. Only one antenna is driven, while optimized parasitic loads are connected on the non-driven elements. The parasitic load values are computed using the Spherical Wave Expansion (SWE) optimization, where an Circularly Polarized (CP) objective radiation is defined. The proposed antenna having an electrical size ka=0.6 exhibits an RHCP radiation in the GPS-L2 band with an 4dBic Gain.
