Abstract
The moment method technique has been developed to examine the scattering properties of a rectangular microstrip patch antenna with a surface resistance. Entire domain sinusoid basis functions without edge condition and roof top sub-domain basis functions are introduced to expand the unknown current on the metal patches. The boundary condition for the electric field was used to derive an integral equation for the electric current. The necessary terms for representing the surface resistance on the patch were derived and were included in the equation in the form of a resistance matrix. Effects of uniaxial anisotropy in the substrate on the complex resonant frequency, the half band width, the radar cross section and the radiation of the microstrip patch antenna are also investigated. Comparative study between our results and those available in the literature is done and showed a very good agreement.
