Gain and bandwidth enhancement of aperture coupled rectangular DRA

Mobile communication plays important role in present era. Bandwidth and gain are inversely proportional in any of the radar and communication systems. In this paper we shall try to achieve both Gain and Impedance Bandwidth with a new approach using aperture coupled DRA embedded with superstrate. Gain achieved is 12.27 dB and impedance bandwidth is enhanced from 11% to 35.85% using superstrate layer with circular patch array.
