Abstract

1324577 Strip - line directional couplers PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 April 1971 [14 Feb 1970] 21548/71 Heading H1W A directional coupler is formed by a "slot line" on one side of a dielectric substrate and a strip line on the other. The slot line is formed by coating one side of the substrate with a layer 2 of conductive material and removing a narrow slot 3. The strip line is formed by a conductive strip 4 on the opposite side. Since the magnetic fields in the slot and strip lines are respectively parallel to and normal to the direction of propagation, there is no coupling unless the lines are oblique to each other, as shown. It is stated that directional coupling is effective over a broad band, e.g. 1 to 12 GHz. The slot line is terminated by open circuits at the edge of the substrate, or by circular cut-outs 5, 6, as shown. Energy is coupled to the line by connecting the conductors of coaxial input and output lines 7, 8 to the conductive layer on either side of the slot. Conventional couplings (not shown) are made to the strip line.
