We study general properties and new applications of the inductive coupling of a superconducting stripline system, which takes advantage of kinetic inductance of thin superconducting films. We formulate the system composed of two striplines inductively coupled through a common electrode as a four-port circuitry by obtaining its scattering coefficients in a general form, and also characterize the system with the coupled-mode theory. Based on the analysis, we propose new-type of kinetic inductance devices for microwave analog-components, such as directional coupler, microwave switch, variable filter, and efficient coupling elements for striplines. Experiments on stripline coupling with this scheme have been also discussed.
