NONRADIOACTIVE DIELECTRIC LINE AND ITS INTEGRATED CIRCUIT

摘要

In a nonradioactive dielectric line, grooves facing to each other are formed in two dielectric plates, a dielectric strip is disposed in both grooves to constitute an NRD guide, projections (P) protruded in the width direction with respect to the direction of electromagnetic-wave propagation are formed at predetermined positions of the dielectric strip (3), and recesses (H) are formed in the inner surfaces of dielectric plates (1) and (2) and engaged with the projections (P). Change of characteristics due to displacement of the dielectric strip is prevented, and the dielectric strip can be easily worked through cutting. Moreover, the characteristics of a transmission line are maintained without disturbing the electromagnetic field distribution of a mode to be propagated.
