Abstract :
The vector finite element-boundary integral method is adopted to formulate the radiation problem for the cavity-backed patch antenna. A robust well-conditioned asymptotic waveform evaluation (WCAWE) is employed to realize fast computing of input impedance of the patch antenna over a wide frequency band. Numerical results are presented to illustrate the robustness of the WCAWE.
