The Bandwidth Enhancement Of U-Shape Microstrip Antenna With Radiating Patch And EBG Insertion

Abstract:

The purpose of this paper is to design a compact size high bandwidth m icrostrip patch antenna with promising efficiency for various wire-less applications. A modified antenna design is proposed to enhance the bandwidth of 30×30 mm rectangular patch antenna via conversion of rectangular patch into U- shape. It is found that bandwidth is improved significantly where as the addition of square PBG structure on ground plane and a parasitic rectangular patch on top surface provide a very good improvement in bandwidth keeping other parameters satisfied. The MOM (method of moment) based technique is used to analyze proposed antenna. The proposed antenna design is able to improve bandwidth about 38.51% in the band of frequency 1.6-2.4 GHz with centre frequency 2.03 GHz.

Keywords: Antenna, photonic bandgap structure, bandwidth, probe feed antenna, MOM.
