In this paper, a novel circularly-polarized annular-ring microstrip patch antenna which is fabricated on an EBG groundplane is presented. This recently proposed annular-ring antenna structure has been shown to be significantly smaller than conventional annular-ring patch antennas, even on standard groundplanes. The addition of the EBG structure to the annular-ring embedded patch yields an increase in the impedance bandwidth, axial-ratio bandwidth and antenna gain by 46 %, 50% and 2.2 dBi respectively, when compared to the same antenna on the same size groundplane without EBG.
