THEORETICAL AND EXPERIMENTAL STUDIES OF ANTENNAS AND ARRAYS IN A PARALLEL – PLATE REGION part Ⅱ – the current distribution and impedance characteristics of coupled antennas in a parallel – plate region

摘要

The current distribution and impedance characteristics of two identical, coupled antennas in a parallel-plate region are studied theoretically and experimentally. The simultaneous integral equations for the current distribution on the coupled antennas have been solved by the method of phase-sequence components. Numerical values for the self and mutual admittances have been calculated for identical antennas of length h = 0. 25λ. and radius a = 0. 0105λ. and for spacings in the range 0. 02 ≤b/ <λ≤1. 0 where b is the distance between the antennas. The current distribution, self and mutual admittances of the antennas have been measured and are found to be in good agreement with theory. A description of the apparatus and measuring techniques is included.
