Abstract

This paper presents the design of a Fabry-Perot/EBG resonator antenna which uses a self-polarizing partially reflecting surface (PRS). The PRS, consisting of an array of rectangular patches, is designed for self-generation of circular polarization. The PRS is designed for highest possible reflectivity and the best axial ratio performance for narrowband applications. Numerical simulations of the proposed antenna configuration predict a peak directivity of 22 dBic and the best axial ratio of 0.85 dB at 9.7 GHz.
