Triple Band Characteristics Of Modified U-Shape Patch With Finite Ground Geometry

Abstract:

The purpose of this paper is to design a compact size high bandwidth microstrip 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 whereas the addition of triple band characteristics is found on modification of 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 in triple band characteristics in 30MHz (1.21-1.24) GHz,  300 MHz. (2.1-2.4) GHz. & 100 MHz (2.9- 3.0) GHz.

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