Abstract
In this paper a small size patch antenna with defected ground structure (DGS) is designed for emergency management applications. The microstrip fed antenna is consisting of rectangular shape partial ground plane and meander line shaped DGS is optimized. The resonant performance of the proposed antenna has been illustrated using method of moment based IE3D EM simulator. The antenna is designed to resonate at 4.94 GHz frequency and possesses the properties of good performance, compact size, low profile and low cost, therefore it is feasible for practical applications in Emergency Management.

Summary
The booming progress in wireless communication system and an increasing demand to integrate different technologies in to small user equipment has remarkably increase the fashion of introducing compact antennas [1]. Microstrip patch antenna, because of its small size, low profile, low manufacturing cost and ease of integration with feed networks, is find extensive applications in wireless communication system [2-3]. In order to further improve the dimensional and resonant characteristics of the patch antennas, several initiatives have been taken in last decade such as slot in the patch, slot in the feed line, fractal geometries, using partial ground planes, DGS and many more [4-6]. In this paper a meander line shaped DGS has been utilized in the partial ground plane of small size patch antenna. In order to further enhance the resonating performance of the proposed antenna, a small size meander shape DGS has been introduced in the ground plane. The structure of the proposed antenna with and without DGS has been shown in figure 1
