Abstract
In this paper, we propose a design of Circular Microstrip Patch Antenna (CMPA) with a circular slot with optimised radius 2.5 mm, and rectangular slot of optimised dimensions of length 10 mm and width of 0.5 mm are etched on the ground plane as Defected Ground Structure (DGS) similar to φ (phi) shape. The DGS concept is used to improve the bandwidth, impedance matching and the relocation of resonant frequency to make the compact CMPA. The size reduction of about 24% is achieved compared to the actual area required to resonate at 5.5 GHz. The bandwidth 600 MHz with respect to centre frequency 5.42 GHz which covers wireless bands such as HiperLAN/1 and HiperLAN/2.. The percentage bandwidth of 11.07% and the average gain of 4 dBi are achieved.
