This manuscript evaluates the different parameter results through experimental set-up using network analyzer and numeric performance through a direct three-dimensional finite difference time domain (FDTD) method of the circularly polarized micro-strip antenna. The circular polarization is achieved by tapering the corners and inserting slits of the micro-strip patch antenna. The FDTD method treats the irradiation of the scatterer as an initial value problem, where as plane-wave source of frequency is assumed to be turn on. The diffraction of waves from this source is modeled by repeatedly solving a finite-difference analog of the time-dependent Maxwell’s equations where time stepping is continued until sinusoidal steady-state field values are observed at all points within the scatterer. Resulting envelope of the standing wave is taken as the steady-state scattered field. Here the problem is solved for the complex antenna structure and proved that smaller dimension area shows better propagation of Electric and Magnetic wave on the surface.
