Abstract

A numerical technique employing the MOM and MEC is presented to study the scattering from slots antenna fed by waveguides with arbitrary terminations

and the frequency response and the RCS are obtained numerically.The rule to determine the number of the base functions is given in detail.It's shown the effect of the waveguides on scattering can not be neglected.By comparing the numerical results with experimental data

the applicability and the validity of the method are established and the errors of numerical results are analyzed.
