Design and Analysis of Co-Planar Waveguide fed Micro Strip Patch Antenna for UWB

Abstract

A Microstrip Patch Antenna (MSPA) is a compact, lightweight and an easy to manufacture structure. However, its common limitation is low bandwidth or low gain or both. The following paper presents an Ultra-wideband (UWB) applicable Microstrip Patch Antenna which is designed using the coplanar technique to enhance its bandwidth. The rectangular patch is given the shape of a spanner with four slots on the inner edge and two hexagonal cuts. It is designed using Taconic TLY tm substrate having a dielectric constant 2.2 and dielectric loss tangent of 0.0009. The simulated model of antenna in ANSOFT HFSS 13.0 gave an impedance bandwidth of 2GHz for 9GHz resonant frequency and S11 of -19.2dB. The proposed antenna was also analysed using parameters including return loss, VSWR, gain and radiation pattern.
