９４参照）。2. Description of the Related Art Recently, when the distance between parallel metal plates is less than a half wavelength, electromagnetic waves of polarized waves parallel to the wall surface of the metal plates are cut off and cannot propagate, but a dielectric strip is placed between the parallel metal plates. When inserted, electromagnetic waves propagate along the dielectric strip, but the radiated wave is completely suppressed by the blocking effect of the parallel metal plate, as shown in FIGS. An NRD line having a structure in which a dielectric line 3 is provided between metal plates 1 and 2 has been developed (Journal of the Institute of Electronics, Information and Communication Engineers published in March 1990.

ある。The problem to be solved is that, when such an NRD line is used for a millimeter wave circuit line or the like, the metal plate of the NRD line is necessary for the circuit configuration of an oscillator or an isolator. It is possible to assemble various circuit elements integrally, but in that case, if all the necessary circuit elements are mounted on one NRD line, layout of the circuit configuration and adjustment problems of each circuit element will occur. This means that it will be impossible.

It is also possible that the end surfaces of the dielectric strips 3 are pressed into contact with each other when the units are joined so that no gap is generated therebetween.
