ABSTRACT:
Coaxial cables can connect both apparatus which are provided inside and outside a closed space without opening a through hole and a gap into a wall and door. In a coupling apparatus for connecting coaxial cables each other through a dielectric plate, there are provided a pair of central electrodes which are respectively connected central conductors of the coaxial cables, an inductor which is connected between at least one of the central conductor and the central electrode, and a pair of outer electrodes which oppose each other through the dielectric plate and surround the central electrodes, respectively, and each of which is connected to each of the outer electrodes. It is possible to connect the coaxial cables through the dielectric (glass) plate.
