In-Band Antenna Coupling Research

Abstract

Theoretical and numerical analyses were performed to develop a computer algorithm for computing antenna mutal gain for arbitrary arrangements and orientations of antennas located in the near-field of each other and operating in the presence of near-field scattering obstacles. The mathematical expressions and algorithm were developed based on the use of the complex far- field electric field data for each antenna. The algorithm, designated as GTSAF, has been implemented and employed to generate coupling data for directive aperture antennas operating (1) on a clear site, and (2) in the presence of a scattering obstacle. Coupling data for a pair of soft dipoles has also been generated via GTSAF, and compared with numerical data obtained via the Method of Moments (MOM). Keywords include: antenna coupling; gain; mutual gain; spherical angular functions; microwave; relector; near-field; far-field; antenna pattern; and stationary phase.
