A simple mathematical formula is proposed for computing the coupling coefficient between two arbitrary antennas that are placed within the other's near-field region. The information required by this expression consists of the associated normalized vector far-field patterns, their relative orientations, and the antenna spacing. To validate our proposed expression, coupling coefficients in several near-field scenarios are computed, including for the case of a practical near-field ultra-high… CONTINUE READING
