Design of a X band W-shaped patch antenna with line feed for UWB applications

An ultra-wideband (UWB) W-shaped patch antenna with defected ground is presented in this paper. Design, simulation and the analysis of the proposed single layer line feed antenna is done in CST Microwave Studio with 10.3 GHz operating frequency. The simulated results reveal that, the presented W-shaped line fed antenna offers a very wide bandwidth of 507 MHz ranging from 10.146 GHz to 10.653 GHz. Good voltage standing wave ratio (VSWR) and radiation pattern characteristics are obtained in the frequency band of interest, which eliminates the possible existence of trade-offs among gain, the design of the antenna and VSWR to obtain desired bandwidth enhancement. Along with the design details of the proposed antenna, simulated results are presented in this work.
