Description of the Related Art Recently, when the interval between parallel plates is less than half a wavelength, electromagnetic waves of polarization parallel to the wall surface of the plates are cut off and cannot propagate. However, if a dielectric line is inserted between the parallel plates, The electromagnetic wave propagates along the dielectric line, but the radiated wave is completely suppressed by the cutoff effect of the parallel plate, and as shown in FIGS. An NRD line having a structure in which a dielectric line 3 is provided between the two has been developed (Transactions of the Institute of Electronics, Information and Communication Engineers, C-1 vol. J7, published in March 1990).

せることができなくなってしまう、ということである。The problem to be solved is that when manufacturing the NRD line, the dielectric line 3 is bonded between the parallel metal plates 1 and 2 with an adhesive. Due to its nature, the adhesive of the dielectric line 3 made of the same is guaranteed for a long period of time in accordance with the change of the environmental temperature, and there is no adhesive which can sufficiently withstand external impact. When connecting unitized NRD lines, the connection between the lines may be shifted or a gap may be formed in the connection to improve the propagation of electromagnetic waves. That means you can no longer do it.
