By J. X. Wan and C.-H. Liang

Abstract:
The well-conditioned asymptotic waveform evaluation (WCAWE) is applied to the MoM solution of scattering from microstrip antennas so that the reduced order model is obtained to efficiently evaluate the frequency response over a broadband in this paper. In the traditional asymptotic waveform evaluation (AWE) method, the ill conditioning usually leads to stagnation in the momentmatching process.The WCAWE eliminates this difficult.A t the same time, to cover the entire bandwidth, a multipoint automatic WCAWE method is also proposed.Numerical examples are given to illustrate the accuracy and robustness of this method.
