Abstract :
In this work, the finite difference time domain method is used to analyze CPW-fed FSA with a thin film ferroelectric. FDTD is apt for analyzing different types of planar antennas on dielectric substrates with different thickness. The resonant frequency, input impedance, bandwidth, radiation pattern and gain of the antenna are presented. The important design considerations necessary for this fabrication are also presented in this study.
