A theoretical and experimental study of the coupling of the flux-flow type Josephson oscillator (FFO) to an external stripline has been carried out to overcome the large impedance mismatch between FFO and the stripline. As a method for an efficient coupling and impedance matching in millimeter-and submillimeter-wavelengths, we have proposed a scheme where the Josephson oscillator is inductively coupled to the stripline via a thin superconducting electrode. A theoretical modeling of the coupling section and the design of the stripline impedance-transformer have been made. By a preliminary experiment to confirm these theoretical results, we have obtained a power of about 10-7emitted from FFO into a stripline in the frequency range from 184 GHz to 193 GHz.
