Planar dielectric line and integrated circuit using the same

摘要

A small and inexpensive planar dielectric line that can be easily connected to electronic parts, such as ICs, and having lower conductor losses. The planar dielectric line includes a dielectric substrate (23) having first and second surfaces opposedly facing each other. A first slot (24) having a predetermined width (w) is interposed between first and second electrodes (21a,21b) on the first surface of the dielectric substrate (23). A second slot (25) having the same width (w) as the first slot (24) is disposed between third and fourth electrodes (22a,22b) on the second surface of the dielectric substrate (23). The first and second slots (24,25) opposedly face each other. The permittivity and the thickness of the dielectric substrate (23) are determined so that a plane electromagnetic wave can propagate in a propagation region of the substrate (23) interposed between the first and second slots (24,25) while being totally reflected on the first surface of the substrate adjacent to the first slot (24) and the second surface of the substrate near the second slot (25). First and second conductive plates (28,29) may be spaced on both sides of the planar dielectric line. A further dielectric material (26,27) may be disposed between the planar dielectric line and each of the conductive plates (28,29). The above-described planar dielectric line may be part of an integrated circuit.
