Claims (12)
- Dispositif d'injection et de transmission à guide d'ondes (1) pour des ondes électromagnétiques, en particulier des micro-ondes, comportant une cavité d'injection (3) munie d'une ouverture (4) d'entrée d'antenne, un circulateur (6), un dispositif d'absorption de charge (14, 15, 16, 17, 17a, 17b, 18, 18a, 18b), une ouverture de sortie (11), un premier conduit de transmission (5) entre la cavité d'injection (3) et le circulateur (6), un deuxième conduit de transmission (10) entre le circulateur (6) et l'ouverture de sortie (11), et un troisième conduit de transmission (13) entre le circulateur (6) et le dispositif d'absorption de charge (14, 15, 16, 17, 17a, 17b, 18, 18a, 18b), caractérisé en ce que le dispositif d'absorption de charge (14, 15, 16, 17, 17a, 17b, 18, 18a, 18b) comporte au moins deux dispositifs d'absorption de charge (17, 18), un dispositif de division de puissance (14) étant agencé entre lesdits au moins deux dispositifs d'absorption de charge (17, 18), lesdits au moins deux dispositifs d'absorption de charge (17, 18) étant reliés par un guide d'ondes (15, 16), les dimensions géométriques du guide d'ondes (15, 16) et l'agencement des dispositifs d'absorption de charge (17, 18) provoquant, lors de l'injection des ondes électromagnétiques, un décalage de phase de 90° par rapport à la longueur d'onde du guide d'ondes (15, 16) entre les dispositifs d'absorption de charge (17, 18).
- Dispositif (1) selon la revendication 1, caractérisé en ce que lesdits au moins deux dispositifs d'absorption de charge (17, 18) ont la même capacité d'absorption de puissance.
- Dispositif (1) selon la revendication 1 ou 2, caractérisé en ce qu'une distance prédéfinie entre lesdits au moins deux dispositifs d'absorption de charge (17, 18) ou une distance prédéfinie entre au moins un dispositif d'absorption de charge (17, 18) et le dispositif de division de puissance (14) est réglable, en particulier au moyen d'un élément de réglage de phase.
- Dispositif (1) selon l'une quelconque des revendications 1 à 3, caractérisé en ce qu'au moins l'un des dispositifs d'absorption de charge (17, 18) est une charge en eau ou une charge à base d'un autre liquide absorbant les champs électromagnétiques, laquelle est guidée en particulier au travers d'un tube (17a, 18a) en matériau électro-isolant, de préférence en verre de quartz.
- Dispositif (1) selon l'une quelconque des revendications 1 à 4, caractérisé en ce qu'au moins l'un des dispositifs d'absorption de charge (17, 18) comporte un tube (17a, 18a) en matériau absorbant les micro-ondes, à l'intérieur duquel peut circuler un liquide refroidissant et/ou absorbant les micro-ondes.
- Dispositif (1) selon le préambule de la revendication 1 ou selon l'une quelconque des revendications 1 à 5, caractérisé en ce que, lors de l'injection d'un champ électromagnétique dans le dispositif (1), un champ magnétique stationnaire règne dans le circulateur (6), lequel est dirigé sensiblement perpendiculairement à la direction de la composante E du champ électromagnétique dans les conduits de transmission (5, 10, 13).
- Dispositif (1) selon le préambule de la revendication 1 ou selon l'une quelconque des revendications 1 à 6, caractérisé en ce que la cavité d'injection (3), le premier conduit de transmission (5), le circulateur (6) et le deuxième conduit de transmission (10) sont disposés dans un carter (2), de préférence commun.
- Dispositif (1) selon la revendication 7, caractérisé en ce que le troisième conduit de transmission (13) et le dispositif d'absorption de charge (14, 15, 16, 17, 17a, 17b, 18, 18a, 18b) sont en outre disposés dans le carter (2).
- Dispositif (1) selon la revendication 7 ou 8, caractérisé en ce que le carter (2) comporte deux corps profilés (2a, 2b).
- Dispositif (1) selon la revendication 9, caractérisé en ce que les corps profilés (2a, 2b) du carter sont sensiblement symétriques.
- Dispositif (1) selon la revendication 9 ou 10, caractérisé en ce qu'une interface des corps profilés (2a, 2b) du carter passe par un côté large des conduits de transmission (5, 10, 13).
- Dispositif (1) selon le préambule de la revendication 1 ou selon l'une quelconque des revendications 1 à 11, caractérisé en ce qu'un dispositif de mesure de la puissance (19, 20, 21) est disposé ou peut être disposé au moins dans ou sur au moins l'un des conduits de transmission (5, 10, 13), le dispositif de mesure comportant un conducteur coaxial (29) et une ouverture de boîtier (22, 23, 24) vers le conduit de transmission (5, 10, 13), l'âme (30) du conducteur coaxial (29) étant reliée par une liaison conductrice avec le pourtour intérieur de l'ouverture de boîtier (22, 23, 24).
