Bandwidth Enhancement of a Microstrip Patch Antenna for C-Band and X- Band by Using New Structure of Defected Ground Technique
In this paper, Defected Ground Structure (DGS) technique has been suggested for the Rectangular Micro-Strip patch Antenna (RMSA) proposed in the previous study for bandwidth enhancement in C-band and X-band with good impedance matching. The aperture proposed in the ground plane has improved the bandwidth approximately six times the bandwidth in the reference antenna without DGS which is about 809 MHz. The value of return loss is also improved by using this technique. The micro-strip patch antenna is simulated using high frequency simulation software FEKO version 5.5.
