Shatabdi Chakraborty, Manoj Kumar Vishwakarma, Shweta Srivastava . Performane Enhancement of Annular Ring Antenna using Photonic Band Gap Structures. International Conference on Communication, Circuits and Systems 2012. IC3S, 2 (June 2013), 22-24.
This paper presents a novel technique of gain enhancement of microstrip antennas which otherwise have a low gain. The annular ring antenna is selected as it has higher radiation efficiency than simple antennas because of two radiating edges. Annular ring antenna with Photonic bandgap (PBG) etched on a ground plane in the higher order mode of TM31 is simulated and experimentally demonstrated. Comparison is done between annular ring antenna with periodic lattice of circular and annular ring structure etched only on ground plane to find out an optimum design of high gain antenna. Details of experimental results are presented and discussed.
