PURPOSE:To suppress leakage between lines without losing the characteristic of a shield type line such as a tri-plate line. CONSTITUTION:An electric groove 20 formed through the elimination of a dielectric body is provided at a position apart from both inner conductors 14, 16 by a prescribed distance. Thus, the resonance frequency in the waveguide mode is shifted to the outside of an operation frequency band to suppress the leakage between the inner conductors 14, 16. |
