Outline of Final Research Achievements

In this study, development of the functional PTFE-waveguide circuits and its integration was attempted based on the fabrication technology using synchrotron radiation, for the purpose of establishing the fabrication technology which could apply directly to submillimeter-wave region (300 GHz > ).
A structure consisting of two E-plane cavity-type couplers, an integrated structure of an E-plane power divider and two horn antennas, and a 4x4 Butler matrix circuit based on combinations of cruciform couplers and intersection circuits were fabricated and evaluated at 180 GHz. The characteristics of these circuits were confirmed by the measurements. It was made clear that the integration of functional E-plane and H-plane waveguide circuits for short millimeter-wave frequencies could be realized.
