Coupling Loop

 

in microwave engineering, a section of transmission line of specified length that is used as the coupling link in loop-type directional couplers. A coupling loop is regarded as a type of four-terminal network with specified parameters. In the designing of loop-type directional couplers, the lengths and the characteristic impedance of coupling loops are calculated, together with certain other parameters that provide the required operating characteristics of such couplers-—namely, the required directivity and isolation—in the frequency band used.
