Abstract
Microstrip antenna is an essential choice for Ultra Wide Band (UWB) applications of its light weight, low profile and easy to form antenna arrays. However, the design of microstrip patch antenna bandwidth is greatly affects by the dielectric substrate material (FR4). In this research, the bandwidth enhancement of MPA was designed by minimizing the dimension of Defected GP (DGP) in GP for Ultra Wide Band wireless applications. But, the antenna design complexity increases with the number of an operating frequency band. In this research, the MPA was designed as small as size of 10×13×1.6 mm and operates on frequency band between 3.1GHz to 10.6GHz for VSWR less than 2. The microstrip patch antenna was designed at 3.1GHz to 10.6GHz using High-Frequency Structure Simulator (HFSS) software. The simulation result shows that the proposed microstrip patch antenna obtained <-10dB of return loss from 3.1GHz to 10.6GHz throughout the frequency range. The measured result proves that the proposed microstrip patch antenna has better characteristics to fulfill the requirements of UWB applications

Summary
The WCS require high quality, cost-effective and Miniaturized Antenna Devices (MAD) with enhanced features because of an increase in data rates and trend of miniature electronics circuits. The MPA is widely used for WCS because of their lightweight, low profile and cost-effective [1]. The MPA contains a radiating patch on one of a dielectric substrate, which has a GP on another side. The microstrip patch is made of conducting material like copper and it can take any effective possible shape. The radiating microstrip patch and the feed lines are usually photo etched on the dielectric substrate. [2].The design of microstrip antennas has benefited from the unrelenting growth in computational power and the increased availability of accurate and efficient methods to numerically solve Maxwell’s equations [3]. The microstrip patch antennas suffer from a number of limitations as patch length is around half a wavelength
