Abstract: The design and simulation of defected ground structure microstrip patch antenna for Worldwide Interoperability for Microwave Access (WiMAX) and Wireless Local Area Network (WLAN) applications are additionally testing as the antenna ought to be little in size, light in weight, easy to manufacture, minimal effort, and simplicity of joining in such gadgets. The target of this work is to plan and creation of an antenna which will be appropriate for WiMAX and WLAN applications with improved gain and optimized bandwidth. WiMAX depend on gauges, for example, IEEE 802.16, intended to work between 2-11 GHz and spreads S, C and X microwave recurrence groups. Metropolitan Area Network (MAN) conventions are in the 2.3 GHz, 2.5 GHz, 3.5 GHz and 5.8 GHz ranges. A planar antenna with imperfect ground plane is proposed and manufactured, 3.5/5.5 GHz WiMAX band, 5.2/5.8 GHz WLAN band, 4/6 GHz satellite correspondence, and different remote correspondence applications. This structure canvassed two groups in which it is extending from 3.34-8.72 GHz implies a band of 5.38 GHz with impedance BW 89.22%. The resonating frequencies are 3.92 GHz and 7.88 GHz with return loss – 35.59 dB and – 31.99 dB, VSWR 1.03 and 1.05 and gain 9.46 dB and 0.14 dB respectively. The second band covers 9.22-13.06 GHz implies a band of 3.84 GHz with impedance BW 34.47%. This resounds at 10.58 GHz with return loss – 55.52 dB, VSWR 1.00 and gain is 7.09 dB. The deliberate outcomes are in great concurrence with reproduced consequences of the proposed antenna.
