LINE TRANSITION DEVICE BETWEEN DIELECTRIC WAVEGUIDE AND WAVEGUIDE, AND OSCILLATOR AND TRANSMITTER USING THE SAME

摘要

PURPOSE: A transition device between a dielectric waveguide and a waveguide is provided to prevent unnecessary radiation and to enable line transition converting with low loss by inserting a part of a dielectric strip of the dielectric waveguide into the waveguide. CONSTITUTION: A line transition device which intervenes between a non radiative dielectric waveguide and a hollow waveguide, includes a dielectric waveguide having a dielectric strip(3) held by a pair of conductors which face each other and a waveguide(4), wherein a part of the dielectric strip(3) of the dielectric waveguide is inserted in the hollow waveguide(4).
