Abstract
A high frequency wiring substrate comprises surface transmission line conductors formed on upper and lower surfaces of a dielectric substrate and surrounded by respective surface ground conductors, and a transmission line interconnect structure for transmitting a high frequency signal between the surface transmission line conductors via an interlayer transmission line conductor surrounded by an interlayer ground conductor and connected at both ends thereof to the respective ends of the surface transmission line conductors by signal conducting through-hole conductors. The surface ground conductors are connected together by two arrays of top-to-bottom through-hole ground conductors, while the interlayer ground conductor is connected to the surface ground conductors by interlayer through-hole ground conductors.
