MICRO CIRCUITS WITH A SCULPTED GROUND PLANE

摘要

A sculpted groundplane is provided so that monolithic dielectric structures are effectively shielded from their immediate surroundings through the implementation of transversely elongated "vias" which form continuous walls that effectively enclose the circuit elements. Further, these walls incorporate a ground plane within this same substrate, which allows for the realization of such structures on a single substrate for microstrip devices, and for realization of stripline structures utilizing only two substrates.
