Abstract:
A microwave-millimeter wave circuit device comprising:a dielectric substrate having a dielectric region;a ground conductor connecting wiring and circuit elements formed on said dielectric substrate;a wiring electrically connected to said circuit elements and crossing over a part of said ground conductor connecting wiring on said dielectric substrate; andground conductor patterns separated from each other by said wiring, being electrically connected to each other via a part of said ground conductor connecting wiring, and forming a coplanar wiring on said dielectric substrate, together with said wiring;wherein at least one end of said part via which said ground conductor patterns are electrically connected to each other is provided with an extended portion which is at least 10 .mu.m long, in order to permit said coplanar wiring to be redesigned in compensation for variations in characteristics of said circuit elements.
