Abstract :
In this paper, the dyadic Green´s functions for an inhomogeneous isotropic grounded slab embedded in an unbounded isotropic half-space fed by an electric three-dimensional (3-D) point-source based on the equivalent two-port circuit representation along the axis normal to the stratification is presented. The working case is extensively investigated by deriving important information on the radiation of the structure and on how to control the radiation on the horizon plane. Numerical results are also presented showing the effects of the electromagnetic parameters on radiation pattern of the integrated structure
