Abstract :
A CPW-fed back-to-back patch antenna printed on a finite-size substrate is analyzed by using the FDTD method. The variations of input impedance and resonance frequency with the widths of the rectangular patch and the substrate are calculated and compared to the existing experimental data. Good agreement between theory and experiment is obtained and a strong finite-size effect is observed.
