Radiation From a Wire in Dielectric Material Over a Conducting Ground Plane,
Abstract
The electromagnetic radiation from an infinitely long wire imbedded in a dielectric layer over a conducting plane was calculated. The current was assumed to be constant along the length of the wire and to vary as e to the -i omega t power. A completely rigorous solution is given in integral form; the integrals were evaluated for small thicknesses, T, of the dielectric layer. It is shown that for thin layers the far field can be approximated by an effective current. The energy loss in the dielectric slab, the radiation resistance, and the directivity were also calculated using the thin layer approximation with a complex dielectric constant. Then the radiation resistance for arbitrary thickness and arbitrary complex dielectric constant was calculated. (Author)
