A dual-band antenna element based on shorted annular ring (SAR) design was introduced recently. The use of the central part of the SAR element as a waveguide radiator facilitates an independent radiation at a higher frequency band. This paper presents the modeling and analysis of the hybrid element using the method-of-moment-based software package FEKO. The analysis includes return loss computations showing the element bandwidth at both frequency bands and the radiation patterns in the E- and H- planes. Feeding the element in phase quadrature produces circular polarizations (CP). The radiation patterns of the CP element are also analyzed using FEKO and the axial ratio performance is subsequently assessed.
