Radiation from coupled parallel-plate waveguides: Ray-optical analysis and experimental results

The radiation pattern of a parallel-plate waveguide with adjacent guides of finite depth is calculated by ray-optical methods. The pattern may be adjusted by changing the width and depth of the parasitic guides. Experiments with a long H plane sectoral horn at about 12 GHz show good agreement with the theory.
