Abstract

In this work, microstrip antenna with W- and V-shaped radiating patches have been proposed. Here square- and circular-shaped modified ground planes have been designed by poly tetra fluoro ethylene (PTFE) substrate with dielectric constant 2.4. Broadband with high gain is obtained by optimum selection of radiating patch with modified ground plane. The ground planes are modified by loading a U-shaped slot. The simulated and measured results are compared. Considering −10 dB impedance bandwidth maximum frequency band of 6.97 GHz (3.04–10.01 GHz) with percentage bandwidth of 106.8% is achieved. The proposed antenna exhibits maximum peak gain of 5.1 dBi. The simulation and measurement have been done by Ansoft designer software and vector network analyzer.
