Abstract

A device for coupling or dividing electromagnetic energy, especially microwaves, between two circuits includes a pair of U-shaped conductors (36, 38) of rectangular cross-section which are coaxially disposed within corresponding slots (34, 36) in an electrically conductive base (30). The conductors have opposing, closely spaced stretches (36c, 38c) at an intersecting juncture in the slots where electromagnetic energy is coupled from one conductor to the other. The conductors are suspended in coaxial relationship within the slots by a pair of coplanar, C-shaped elements (42) which are slidably supported within a second pair of slots (43) in the base and each have cutouts (42a) therein in which the conductors are closely received. A spacer (40) maintains a preselected gap between the opposing stretches of the conductors and is provided with tapered ends (40a, 40b) which cooperate with beveled surfaces (38a, 38b) on the conductors to prevent relative lateral movement between the conductors.
