What is the working principle of waveguide loop couplers?
May 21, 2025
The working principle of waveguide loop couplers revolves around electromagnetic coupling through a precisely designed loop structure inserted into waveguides. A Waveguide Loop Coupler utilizes a small conductive loop positioned within the waveguide to sample a portion of the electromagnetic energy flowing through the main transmission path. This coupling mechanism is based on the principle of mutual inductance, where the loop intercepts the magnetic field lines of the propagating wave, creating an induced current proportional to the power in the main guide. The orientation, size, and positioning of the loop determine the coupling factor, directivity, and overall performance characteristics, making waveguide loop couplers essential components in high-frequency microwave systems requiring precise signal sampling and power measurements.
