The need in today's wireless applications is to design antennas that are compact, robust and effortless to integrate with RF circuit components. Microstrip patch antenna is one such type which satisfies these requirements. But the two main performance parameters of an antenna namely the gain and the bandwidth are near to the ground for patch antennas. Usually the gain range of a patch antenna is 1–2dB...
