A substrate integrated waveguide (10) comprises a top conductive layer (14) and a bottom conductive layer (15) provided on either sides a substrate (11). At least one wall (12, 13) of conductive material is provided in the substrate (11) to define, together with the top and bottom layers (14, 15), the waveguide. The at least one wall (12, 13) comprise a multitude of thin conductive wires densely arranged close to each other in the substrate (11) and having respective short ends connected to the top and bottom layers (14, 15). The high number of wires per surface unit in the wall (12, 13) effectively prevent significant amount of power leakage through the wall (12, 13) during operation of the substrate integrated waveguide (10).

The material is a composition including a cycloolefin resin (A) and an elastomer ingredient (B) in which the blending proportion of the cycloolefin resin (A) to the elastomer ingredient (B) and the proportion of unsaturated double bonds contained in the elastomer ingredient (B) are in specific ranges.
摘要:
A reduced-cross-sectional area, triad transmission line is formed by plating or metallizing surface area of a substrate, along the edge of a slot cut through the substrate. The cross-sectional area of such conductors that faces each other is reduced, reducing the signal coupling between them when they are carrying high-frequency signals. An intervening ground plane between them is provided by metallization on the slot bottom that is held at ground potential.
