ABSTRACT:
A directional coupler uses non-metallic slotted spacers at the edges of a pair of coupled lines. The spacers are adjustable in their vertical position and thereby provide continuous coupling fine-adjustment. The spatial relationship between the coupled lines is therefore adjustable and does not depend upon extremely tight manufacturing tolerances.
