A compound dielectric multi-conductor transmission line and devices constructed therefrom

摘要: A transmission line comprising a multi-layer dielectric slab structure including: substrate layer (30) having thickness ds and permittivity epsilons; conductive ground plane (31) on the bottom surface of (30); guiding (32) h epsilong, where epsilong > epsilons, attached to top at least one elongated relatively narrow loading strip (33) width W, dl, epsilonl, (32); coating (34) (32). Such permits single mode propagation over wide band. Radiation losses due coupling desired modes conductors are furthermore reduced polarization dominant is such as render said insensitive small deviations from parallelism among different interfaces.
