Design of ultra small microstrip patch antenna for wireless communication applications

Abstract

This paper presents a narrow band microstrip patch antenna for wireless communication. A microstrip patch antenna consists of a radiating patch on one side of a dielectric substrate and has a ground plane on the other side. The main radiator is a rectangular patch made up of copper. The advantages of this type of narrowband antennas are planar, smaller in size, simple structure, low in cost and easy to be fabricated, etc. thus attractive for wireless applications. Simulation of the antenna and subsequent adjustments of parameters gives apt values for the antenna to work efficiently at low cost. At the later stage, comparison between different antenna shapes has been provided and comparative study has been done in order to list the advantages of each shape and decide which shape is best suited for the desired wireless frequency of 1.7GHz. Also this work explores the performance enhancement of multiple patch antennas. Comparative studies between the array and individual unit have proved the betterment of results for wireless applications at 1.7GHz.
