Abstract
Groove guides have been known for many years. No practical microwave circuits have yet been described although these types of transmission lines could be used in many cases. This paper discusses the physical realizability of some wide band designs such as matched load, directional coupler, hybrid coupler, bend and phase shifter. Both closed and open groove guides have been investigated. Optical type components seem to be inappropriate for groove guide transmission. The best way to design components for these guides is to adapt those of standard rectangular guides, which perturb only theRffields in the vicinity of the narrow walls and to optimize the dimensions of the groove structure as a function of the losses and the symmetry of the induced spurious modes.
Analyse
Le guide rainuré est connu depuis plusieurs années mais aucun circuit pratique n’a été décrit pour ce type de lignes de transmission. Les auteurs discutent la réalisation de quelques composants large bande fonctionnant à la fois pour les guides rainurés ouverts ou fermés latéralement: charge adaptée, coupleur directif coupleur hybride, coude et déphaseur. Les circuits appliquant les principes de l’optique géométrique sont souvent peu satisfaisants. Il est préférable d’adapter les composants connus des guides rectangulaires — ceux notamment qui introduisent des perturbations du champ électromagnétique au voisinage des parois approchées — et d’optimiser ensuite les dimensions en fonction des pertes acceptées et de la symétrie des modes parasites induits.
