Abstract
An energy coupler (10) includes a movably adjustable energy coupling sleeve (16), and a coupling transmission line (18) operatively coupled to the movably adjustable energy coupling sleeve (16) to provide adjustable coefficient coupling with a transmission line (14), such as a coaxial transmission line. In one embodiment, the movably adjustable energy coupling sleeve (16) is configured to rotatably move to provide selectable energy coupling with the coaxial transmission line (14).
Claims11
A coaxial cable comprising:
- a coaxial cable including a transmission line, a portion having an off center transmission line, dielectric material surrounding at least a portion of the transmission line, and a shield that is coaxial with the transmission line, the shield having an opening formed therein;
- and
- an energy coupler disposed about the coaxial cable proximal to the opening and including a dielectric sleeve, a coupling transmission line operatively coupled with the dielectric sleeve, an outer shield, and at least one terminal that is electrically coupled to the coupling transmission line;
- wherein the sleeve is rotatable about the portion to provide a variable distance between the coupling transmission line and the off center transmission line.
