Abstract

Cost and performance are the primary driving forces of millimeter-wave technology for use in wireless communications systems. They have stimulated an ever-growing interest in seeking new circuit building blocks to cope with such demands. In this work, we present an innovative circuit building block concept, which is based on the co-layered geometry of planar circuits and NRD-guides (surface-mounted NRD-guides), featuring adjacent co-layered hybrid integration of two dissimilar structures without resort to intermediate aperture coupling. Our simulation and experiments of several co-layered schemes including microstrip planar circuit/NRD-guide and coplanar waveguide NRD-guide structures indicate that low transmission loss and good return loss can be achieved for the hybrid interconnects. Such results have validated our proposed concept and the usefulness of these new schemes. This scheme is rather unique and will be useful if monolithic circuits are required to interconnect with the NRD-guide. In addition, this proposal points to a unique possibility of designing new interconnects of adjacent interface-to- interface or layer-to-layer planar circuits that could be located over neighboring interfaces via dielectric waveguide. Some technical features of the proposed schemes are discussed with respect to transmission efficiency between these structures. Our work demonstrates interesting electrical and design aspects of these new circuit building blocks for millimeter-wave and quasi-optical applications.
