This paper presents the modelling and design of an omni-directional (azimuth plane) cylindrical patch antenna operating at 2.4GHz and the directivity enhancement in the elevation plane by means of cylindrical Electromagnetic Bandgap (EBG) surfaces. The EBG surfaces are initially designed using planar modal analysis. They are used as Partially Reflecting Surfaces (PRS) and placed around the cylindrical patch at a resonant distance corresponding to the desired operating frequency. This distance is initially approximated using a simple analytical formula. Full-wave periodic analysis provides accurate results of the antenna operating frequency and performance. A finite 2.5 wavelength antenna has been simulated using a 3D full-wave software package and the results are presented.
