Antenna Coupling/Isolation Analysis: Generation to 3-D
Abstract
This report summarizes a generalized formulation for three-dimensional antenna coupling and isolation problems. The formulation is developed for a generic transmit/receive configuration. The formulation is based on representing the boundary conditions arising in the problem by using integro-differential representations of Maxwell's equations. To streamline the derivations, integral operators are introduced. The resulting system of coupled equations for the electric and magnetic fields is solved using the Method of Moments (MM) technique. Specifically, the Galerkin variant of this technique is adopted here, resulting in a symmetric system matrix for the problem. The formulation discussed here is specialized to the two-domain case. This refers to problems where the antenna or array is embedded in a conducting surface constituting one domain. The second domain is an intervening region that is penetrable. Depending on the nature of the penetrable region, it provides the isolation or coupling between the transmit or receive antennas and arrays. The resulting generalized formulation has been implemented with computer software that is an adaptation of the MM-based CARLOS code. Discussion of the associated numerical implementation and software are documented elsewhere and omitted from this report. (2 figures, 8 refs.)
