Abstract :
This paper presents a new method to realise omni-directional antennas for wireless communication applications such as wireless local area networks (WLAN) by incorporating cylindrical metallodielectric electromagnetic band gap (MEBG) structures. These structures behave as partially reflecting surfaces (PRS) and significantly enhance the directivity of simple radiating sources. Micro-stripes (TLM) is used for the simulation and design of cylindrical antenna structures. A novel cylindrical antenna that operates at 2.33 GHz and is fed by a balanced dipole was constructed to illustrate the design methodology.
