La présente invention concerne un guide d'ondes d'antenne parabolique pour l'émission et la réception d'ondes hertziennes. The present invention relates to a parabolic antenna waveguide for the transmission and reception of radio waves.
L'invention vise plus précisément un guide d'ondes tel qu'illustré par les figures 1 et 2 annexées, la figure 1 étant une vue en coupe longitudinale et la figure 2 une vue en coupe suivant le plan F-F de la figure 1. The invention relates more precisely to a waveguide as illustrated by the appended FIGS. 1 and 2, FIG. 1 being a view in longitudinal section and FIG. 2 a view in section along the plane F-F of FIG. 1.
Tel que représenté sur ces figures, le guide d'ondes comprend un élément tubulaire principal 1 présentant une partie tubulaire 2 de section constante prolongée par une partie évasée 3 sensiblement tronconique La partie tubulaire 2 porte plusieurs cavités cylindriques 4 réparties radialement autour de l'axe de l'élément tubulaire principal 1. As shown in these figures, the waveguide comprises a main tubular element 1 having a tubular part 2 of constant section extended by a flared part 3 substantially frustoconical The tubular part 2 carries several cylindrical cavities 4 distributed radially around the axis of the main tubular element 1.
L'axe de chaque cavité cylindrique 4 est situé dans un plan F-F perpendiculaire à l'axe de l'élément tubulaire principal 1. The axis of each cylindrical cavity 4 is located in a plane F-F perpendicular to the axis of the main tubular element 1.
Chaque cavité 4 débouche dans l'élément principal 1 par un conduit 5 de section identique ou rétrécie par rapport à la section de la cavité 4. Each cavity 4 opens into the main element 1 through a duct 5 of identical or narrowed section relative to the section of the cavity 4.
Le guide de l'onde présente les dimensions caractéristiques suivantes : - La section de la cavité proprement dite (L 1 et L2) - La profondeur de la cavité (L3) - La section de la frontière avec le guide d'ondes (L4 et L5) - La distance de l'axe de la cavité avec les éventuels changements de section du guide d'ondes principal (LS, 01 et D2). The waveguide has the following characteristic dimensions: - The section of the cavity proper (L 1 and L2) - The depth of the cavity (L3) - The section of the border with the waveguide (L4 and L5) - The distance from the axis of the cavity with any changes in section of the main waveguide (LS, 01 and D2).
<Desc/Clms Page number 2> <Desc / Clms Page number 2>
Classiquement dans les procédés de moulage, des dépouilles de 0. 5 à 10 permettent l'obtention du guide d'ondes principal avec des variations de dimensions compatibles avec l'utilisation. Conventionally in molding processes, spans from 0.5 to 10 allow the main waveguide to be obtained with variations in dimensions compatible with use.
Le but de la présente invention est de concevoir un guide d'ondes présentant les cavités mentionnées ci-dessus. The object of the present invention is to design a waveguide having the cavities mentioned above.
Suivant l'invention, ce guide d'ondes est caractérisé en ce qu'il est constitué de deux parties distinctes assemblées l'une à l'autre suivant un plan dans lequel sont situés les axes desdites cavités. According to the invention, this waveguide is characterized in that it consists of two separate parts assembled to one another along a plane in which the axes of said cavities are located.
La figure 3 annexée est une vue en coupe longitudinale d'un guide d'ondes selon l'invention. Figure 3 attached is a longitudinal sectional view of a waveguide according to the invention.
La figure 4 est une vue en coupe partielle montrant à plus grande échelle l'assemblage étanche entre les deux parties du guide d'ondes. Figure 4 is a partial sectional view showing on a larger scale the sealed assembly between the two parts of the waveguide.
Les figures 5 et 6 sont des vues en perspectives des deux parties du guide d'ondes. Figures 5 and 6 are perspective views of the two parts of the waveguide.
<Desc/Clms Page number 3><Desc / Clms Page number 3>
Comme montré par la figure 3, le guide d'ondes est constitué de deux parties distinctes 1A, 1B assemblées l'une à l'autre suivant un plan dans lequel sont situés les axes des cavités 4. As shown in FIG. 3, the waveguide is made up of two distinct parts 1A, 1B assembled to one another along a plane in which the axes of the cavities 4 are located.
Chacune des deux parties distinctes 1A, 1B du guide d'ondes comporte à l'une de ses extrémités un flasque circulaire 6A, 6B dans lequel sont réalisées des demi cavités 4 destinées à constituer des cavités fermées lorsque le flasque 6A de l'une des parties est assemblé contre le flasque 6B de l'autre partie. Each of the two separate parts 1A, 1B of the waveguide comprises at one of its ends a circular flange 6A, 6B in which are produced half cavities 4 intended to constitute closed cavities when the flange 6A of one of the parts is assembled against the flange 6B of the other part.
De préférence, le guide d'ondes est en métal conducteur moulé. Dans ce cas les demi cavités 4 sont moulées dans chaque flasque 6A, 6B. Preferably, the waveguide is made of molded conductive metal. In this case the half cavities 4 are molded in each flange 6A, 6B.
Comme montré par les figures 3, 4, 5,6 chaque flasque 6A, 6B comporte près de sa périphérie une série de trous 7 permettant le passage de vis d'assemblage 8 (voir figure 4) des deux flasques 6A, 6B. As shown in FIGS. 3, 4, 5, 6 each flange 6A, 6B comprises near its periphery a series of holes 7 allowing the passage of assembly screws 8 (see FIG. 4) of the two flanges 6A, 6B.
Par ailleurs, la figure 4 montre qu'un joint d'étanchéité 9 est compris entre les deux flasques 6A, 6B. Furthermore, Figure 4 shows that a seal 9 is between the two flanges 6A, 6B.
Le joint d'étanchéité 9 est de préférence un joint torique logé dans une gorge annulaire réalisée dans chaque flasque 6A, 6B. The seal 9 is preferably an O-ring housed in an annular groove made in each flange 6A, 6B.
Le guide d'ondes que l'on vient de décrire présente notamment les avantages suivants :
Sa conception simple et peu coûteuse à réaliser en grande série permet : The waveguide just described has the following advantages in particular:
Its simple and inexpensive design to produce in large series allows:
<Desc/Clms Page number 4><Desc / Clms Page number 4>
- D'obtenir des profondeurs de cavités indépendantes du diamètre du guide d'ondes principal. - Obtain depths of cavities independent of the diameter of the main waveguide.
- D'obtenir des fentes de couplage de sections différentes de celles de la cavité si nécessaire. - Obtain coupling slots of sections different from those of the cavity if necessary.
- D'obtenir un nombre et une répartition des cavités sans contraintes particulières. - Obtain a number and distribution of cavities without any particular constraints.
- D'assurer l'étanchéité par un joint torique. - Ensure tightness by an O-ring.
- D'assurer la continuité électrique entre les deux parties du guide d'ondes.- Ensure electrical continuity between the two parts of the waveguide.
