In a non-radiative dielectric line, slots opposing each other are respectively formed on two conductive plates and a dielectric strip is disposed within both the slots to form a NRD guide. Convex portions "P" protruding in the lateral direction to the propagating direction of an electromagnetic wave are formed at a predetermined position of the dielectric strip 3 while concave portions "H" are formed on internal surfaces of the slots in the conductive plates 1 and 2 so as to mate the both of them with each other. Variations in characteristics due to the positional slippage of the dielectric strip and so forth are prevented, and even when the dielectric strip is produced by machining, etc., the process is easily performed. Characteristics as a transmission line are also maintained without disturbing the electromagnetic field distribution in a mode to be propagated.
On forme dans une ligne diélectrique non radiative des rainures dans deux plaques diélectriques et on dispose dans lesdites rainures une bande diélectrique de manière à constituer un guide NRD, puis on forme des protubérances (P) transversales par rapport au sens de propagation des ondes électromagnétiques en des points donnés de la bande diélectrique (3), et sur les surfaces intérieures des plaques diélectriques (1, 2), des évidements (H) dans lesquels s'engagent les protubérances (P). On évite ainsi les modifications de caractéristiques dues au déplacement de la bande diélectrique, tandis qu'il est facile de travailler sur la bande par des découpures. De plus les caractéristiques de la ligne de transmission sont maintenues sans perturber la distribution du champ électromagnétique en mode propagation.
