Abstract
The invention is connected with a microwave structure, and particularly with the improvement of a microwave circuit of the three plate construction having a plurality of independent circuits formed in an inner level that is sandwiched by two dielectric conductor boards having grounded conductive layers on their outer surfaces, wherein a plurality of through holes are formed to penetrate through the dielectric boards between the neighboring circuits and extending between the conductive layers on the outer surfaces of the boards, the inner surfaces of the through holes being metallized to connect the grounded conductive layers to provide a ground shield between the neighboring circuits.
