Title (EN) RADIATION DEVICES PROVIDING HYPERFREQUENCY CIRCULARLY POLARIZED WAVES AND THEIR USE IN THE FIELD OF MICROWAVE APPLICATION
(FR) DISPOSITIFS RAYONNANTS PRODUISANT DES ONDES HYPERFREQUENCES POLARISEES CIRCULAIREMENT ET LEUR UTILISATION DANS LE DOMAINE DES APPLICATEURS A MICRO-ONDES
Abstract: front page image
(EN)A radiation device, operating in the range of microwaves or hyperfrequencies, providing circularly polarized waves, comprising a wave guide (5) and antennas carried by such guide, which combine the use of slots and spirals. This device may be part of a set of similar devices. It allows to provide levels of radiation power equal from one antenna to another (4), or, on the contrary, different from one antenna to another, according to the needs. Its utilization in an industrial applicator makes possible the microwave treatment of products causing strong reflexions, either because the loss factor thereof is insufficient, or because they are contained in open metal containers (3), or because they contain themselves metal portions, or because they present heterogeneities or anisotropies.
(FR)Dispositif rayonnant, fonctionnant dans la gamme des micro-ondes ou hyperfrequences, fournissant des ondes polarisees circulairement, comportant un guide d"ondes (5) et des antennes portees par ce guide, qui combinent l"emploi des fentes et d"helices. Ce dispositif peut faire partie d"un ensemble de dispositifs semblables. Il permet d"obtenir des niveaux de puissance rayonnee egaux d"une antenne a l"autre, ou, au contraire, variables d"une antenne a l"autre, suivant les besoins. Son utilisation dans un applicateur industriel rend possible le traitement par micro-ondes de produits provoquant de fortes reflexions, soit parce que leur facteur de perte est insuffisant, soit parce qu"ils sont contenus dans des recipients metalliques ouverts (3), soit parce qu"ils contiennent eux-memes des parties metalliques, soit parce qu"ils presentent des heterogeneites ou des anisotropies.
