Abstract
Abstract An RF directional power monitor includes an air dielectric coaxial line section has inner and outer connectors separated by insulating supports and is equipped with printed circuit board terminals at opposite ends of the line. Provision is made for a multiple turn coupling loop between spaced openings in the outer coaxial conductor to permit a single basic assembly to be used over a wide RF power and frequency range merely by changing the number of turns of the coupling loop.

Claim 1
Independent Claim
145 words
A high frequency coupler including in combination: a coaxial line having axially disposed inner and outer conductors; support means for spacing and supporting the inner conductor within the outer conductor; first and second axially spaced openings in the outer conductor; a coupling loop having a plurality of turns and which extends through the first opening and in the space between the inner and outer conductors to the second opening, returns over the outside of the outer conductor to the first opening and extends from the first opening to the second opening in the space between the inner and outer conductors to form the second and any additional ones of the Plurality of turns of the coupling loop, so that current flowing in the turns of the loop located between the inner and outer conductors flows in the same direction simultaneously in all of the turns.
