Design Characterization of Rectangular Microstrip Patch Antenna for Wi-Fi Application

Abstract

The main aim of the paper is to design and simulate an inset fed rectangular microstrip patch antenna and study the effect of antenna dimension Length (L), Width (W), substrate parameter relative dielectric constant ( ) substrate thickness (h) and radiation parameters. The result is performed by thickness of 1.57mm of substrate and Rogers RT/duroid 5880 (tm) with dielectric constant of 2.2, S- band frequency 2.4GHz have observed the better result. In the recent years the development in communication systems requires the development of low cost, minimal weight, low profile antennas that are capable of maintaining high performance over a wide spectrum of frequency. This technological trend has focused much effort into the design of a Microstrip patch antenna. The proposed antenna design on different resonant frequencies and analyze the result of all operating frequency between 1GHz to 10GHz, when the proposed antenna designs 2.4GHz operating frequency. At 2.4GHz the verified and tested result has done in Ansoft HFSS version 11.It has observed the Return loss = -30.8 dB, VSWR =1.05 and Directivity = 6.732 dB in this paper. An omnidirectional radiation pattern and stable gain are observed.
