Abstract
A transmission line transition for coupling electromagnetic energy between different transmission lines includes first and second dielectric substrates laminated to each other and a waveguide tube attached to the first dielectric substrate. The laminated dielectric substrate provides a dielectric waveguide having a first end short-circuited and a second end communicating with a hollow interior of the waveguide tube. An antenna connected to a planar line is disposed in the dielectric waveguide and spaced from the short-circuited end of the dielectric waveguide by a predetermined distance in a longitudinal direction of the waveguide tube to excite and to be excited by the waveguide tube. The dielectric waveguide has a cross-sectional area smaller than that of the interior of the waveguide tube and coincides with the interior of the waveguide tube in the longitudinal direction.
