Abstract
A microstrip line, formed by a conductor strip on one side of a dielectric substrate and by a ground-plane layer on the other side thereof, is electrically coupled to another microwave-transmission line, formed by a slot in the ground-plane layer paralleling the strip, with the aid of a supplemental conductor element establishing a virtual short-circuit at an off-axial location on a portion of the strip overlapping the slot. The supplemental conductor element may be a wire, traversing the substrate, or a lateral extension of the strip defining an open-circuited quarter-wavelength line with the ground-plane layer.
