Abstract

The goal of this research is to enhance the bandwidth of a rectangular patch microstrip antenna. The bandwidth of the antenna is tuned by analyzing the various dielectric substrate mat erials, height & width, coaxial feed line, input and output impedances with effective dielectric constant s, and effective length. The suggested rectangular microstrip patch antenna operates at a frequency of 4.4 GHz. As a function of various frequencies, the VSWR, S11 and efficiency are analyzed. This analysis emphasizes that a low dielectric constant with an appropriate height of the dielectric substrate material for a microstrip patch antenna is utterly important in terms of enhancing bandwidth as well as a surface wave. This analysis gives better results for the RT-Turoid and attains a bandwidth of 56.65% at 4.4 GHz of resonance frequency. This high bandwidth makes it useful in many wideband applications.

Keywords: Dielectric substrates; Rectangular patch; Bandwidth; Coaxial Feedline; S11 parameter; VSWR and Efficiency
