Abstract
The influence of the edge region of a waveguide dichroic plate is examined through a series of experiments involving modifications to the ground plane surrounding the area occupied by the guides. Crosspolar levels as high as −23 dB can be produced by the edge but with proper design can be reduced below −33 dB.Keywords
