Modeling Antennas and Scatterers of Arbitrary Shape Embedded in Layered Dielectric Media.

摘要

A general approach is developed for the rigorous analysis of radiation, scattering, and guidance of electromagnetic fields by conducting objects for arbitrary shape embedded in layered dielectric media. This approach is based on the mixed-potential form of the electric field integral equation, which is amenable to the existing, well-established numerical solution procedures, originally developed for objects in homogeneous space. Numerical results are presented for surfaces and wires that penetrate an interface between dissimilar media and for open microstrip transmission lines of finite thickness. Computed and measured data are also given for coax-fed rectangular and triangular microstrip patch antennas. (RRH)
