Abstract
A theoretical method is presented to analyze the radiation characteristics of an infinite phased array of horizontal dipoles in the presence of adjacent vertical wires protruding out of the ground plane. Green's functions for vertical and horizontal delta -sources in a unit cell are derived in terms of Floquet modes. By superposition of the Green's functions, the E- and H-fields in a unit cell are obtained. The current distributions and the input radiation impedances of the dipole array are obtained by making use of the method of moments. Numerical examples are given to show the coupling effects. Measurements of the radiation impedances in a waveguide simulator with and without the coupling effects due to the vertical wires have been conducted to verify the theoretical model. The general trend of measured data has been predicted quite well by the theoretical computation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
