Abstract

The electric field integral equation (EFIE) for planar circuits and antennas is usually solved with a spectral computation of the Green´s functions. The method of moments solution of the EFIE becomes cumbersome for three-dimensional (3D) metallic surfaces in an arbitrary multilayered medium. Here, it is demonstrated how some of the numerical work can be replaced by analytical computations for 3D planar structures by using the closed form expressions for the spectral Green´s functions. An example of a two-conductor line short circuited with a vertical metallic plate is presented
