Abstract: Compact fractal boundary dual band Omni-directional antenna is proposed for circular polarization (CP). Total four antennas were proposed by taking different fractal curves as the sides of a square patch. Optimization of indentation parameter is done to design the compact dual band antennas. The proposed antenna works at dual band of operating frequencies at 5.4 GHz and 8 GHz. Results show that an excellent CP is attained with dual band characteristics utilising a single probe feed, besides diminution in the antenna size by applying fractal boundary concept.
