Abstract
A device with a nonradiative dielectric waveguide which operates in a microwave band or in a millimeter wave band. The device with a nonradiative dielectric waveguide is, for example, an oscillator, a circulator, a coupler or the like. The device has a pair of parallel conductors, a dielectric strip which is disposed between the conductors and propagates a high-frequency electromagnetic wave in a specified mode, a mounting surface which is formed on one of the conductors, and an end surface which is defined by an end of each of the conductors so as to be vertical to a traveling direction of the electromagnetic wave propagated in the dielectric strip. An end of the dielectric strip is exposed at a corresponding end surface of the device.
