Influence of antenna parameters on the radiation of a rectangular microstrip patch antenna

This paper present a rigorous analysis of rectangular microstrip patch over ground planes with substrates isotropic is presented. The dyadic Greenpsilas functions of the problem are efficiently determined in the vector Fourier transform domain. The integral equation for the unknown patch current and field are solved numerically by applying the Galerkin method of moments. The TM set of modes issued from the magnetic wall cavity model are used to expand the unknown current on the patch. Also, the same basics functions are used for approximating the field in accordance with the concept of complementary electromagnetic structures. The validity of the solution is tested by comparison of the computed results with experimental data.
