The Finite Difference Time Domain (FDTD) full wave analysis technique is applied to microstrip antenna designed on LDPE/titania graded dielectric substrates. The FDTD simulation generates data which helps in visualizing the time progression of vector fields throughout the three-dimensional solution space. It gives a physical insight of complex field interactions at different stages of field propagation. The radiation response of the microstrip antenna is analysed by finding the scattering parameters by taking Fourier transformation of the transient $E$ field component. The $S_{11}$ obtained using this method for the graded substrate antenna is compared with the measured and simulated (using CST Microwave Studio) results which shows proximity.
