Stripline termination circuit having resonators

A technique of realizing a termination circuit using coupled resonators in stripline configuration of a circuit presented. The circuit absorbs RF energy incident on its input over a frequency band of interest, and dissipates it in to the dielectric substrate, thereby acting like an effective termination in the frequency band. The resonant elements may be constructed in edge-coupled or broad-side coupled stripline configuration. The technique may be extended to build microstrip line termination with edge-coupled resonators. The technique may further be extended to realize attenuators over a narrow band.
