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.
