Analysis of Capacitive Fed Microstrip Antenna for Wideband Applications

The parametric analysis of capacitive fed microstrip antenna suspended above the ground plane has been presented in this paper. For the analysis purpose, the reference structure has been taken from paper [3]. In this paper parameters of capacitive fed microstrip antenna is varied and the corresponding variation of radiation performance (return loss, bandwidth) is analyzed using IE3D software. A comparative plot of variation of return loss with frequency for capacitive coupled rectangular microstrip antenna is observed for each parameter.
