Ring Shape Micro-strip Patch Antenna for UWB applications

Abstract

In this paper, ring microstrip patch antenna structures with 3 different DGS Structure. Antennas have been analyzed, investigated and optimized by CST MW studio tool. Proposed designs are based on the concept Defected Ground Structure while its overall dimensions are kept constant. The objective is to design UWB antenna within the range of 3-15GHz. The presented antennas are simulated on cheaper and lossy FR-4 substrate, and their parameters are measured and compared. In this,maximum VSWR value of less than 1.5 has been achieved. At the end a, good agreement has been obtained between simulated and measured parameters.
