Description

La présente invention concerne un élément rayonnant à plans parallèles, fonctionnant de préférence dans le domaine des hyperfréquences. Cet élément est utilisable comme source primaire ou comme répartiteur hyperfréquence d'une antenne-réseau, délivrant une onde plane.The present invention relates to a radiating element with parallel planes, preferably operating in the microwave domain. This element can be used as a primary source or as a microwave distributor of a network antenna, delivering a plane wave.

Par antenne à plans parallèles, on entend une antenne essentiellement constituée par deux plaques parallèles limitées par un fond cylindro-conique illuminé par une source placée sur sa droite focale. Lorsque le fond est cylindro-parabolique, on parle d'antenne Pill-Box ou d'antenne "Fromage" suivant la hauteur séparant les deux plaques.By antenna with parallel planes is meant an antenna essentially constituted by two parallel plates bounded by a cylindro-conical bottom illuminated by a source placed on its focal line. When the bottom is cylindro-parabolic, we speak of Pill-Box antenna or "Cheese" antenna depending on the height separating the two plates.

Pour pallier l'effet d'occultation de l'ouverture rayonnante de l'élément rayonnant par la source, il a été réalisé des éléments du genre "fromage" ou Pill-Box repriés conformément à la figure 1. Cependant, cette solution présente l'inconvénient d'avoir une profondeur trop importante, ce qui peut être gênant dans la réalisation d'antennes-réseaux linéaires ou planes.To overcome the effect of concealing the radiating opening of the radiating element by the source, elements of the genus "cheese" or Pill-Box have been made, sorted in accordance with FIG. 1. However, this solution presents 'disadvantage of having too great a depth, which can be annoying in the production of linear or planar array antennas.

Le but de l'invention est de réaliser un élément rayonnant à plans parallèles transformant une onde sphérique en une onde plane, et de faible encombrement en profondeur et pouvant servir d'alimentation équiphase pour une antenne-réseau linéaire ou pour une antenne dalle.The object of the invention is to produce a radiating element with parallel planes transforming a spherical wave into a plane wave, and of small overall depth and which can serve as an equiphase supply for a linear array antenna or for a slab antenna.

Dans l'art antérieur, les sources rayonnantes d'un réseau linéaire peuvent être alimentées par un guide d'onde dont l'énergie est prélevée par des sondes régulièrement espacées, qui peuvent être des fentes ou des plongeurs ou encore des coupleurs. Un inconvénient d'une telle solution est sa disper- sivité, c'est-à-dire que la loi de phase de l'onde émise varie avec la fréquence, en raison de la difficulté qu'il y a d'adapter l'entrée de l'alignement des sondes avec la fréquence.In the prior art, the radiating sources of a linear array can be supplied by a waveguide whose energy is taken up by regularly spaced probes, which can be slots or plungers or even couplers. A disadvantage of such a solution is its dispersiveness, that is to say that the phase law of the transmitted wave varies with frequency, due to the difficulty there is in adapting the input of probe alignment with frequency.

Une autre solution pour alimenter les sources rayonnantes d'un réseau linéaire est de réaliser un "chandelier" alimenté par une seule source au moyen de guides d'ondes, ou de fils coaxiaux ou bien encore réalisé en technologie triplaque. Cependant une telle réalisation au moyen de guides d'ondes ou de fils coaxiaux présente des pertes dues aux longueurs des lignes, et est encombrante et coûteuse. La réalisation en technologie triplaque présente des pertes dans les diélectriques.Another solution for supplying the radiating sources of a linear network is to produce a "candlestick" supplied by a single source by means of waveguides, or coaxial wires or else produced in triplate technology. However, such an embodiment by means of waveguides or coaxial wires has losses due to the lengths of the lines, and is bulky and expensive. The realization in triplate technology presents losses in the dielectrics.

L'invention a pour but de réaliser un élément rayonnant à plans parallèles fonctionnant dans le domaine des hyperfréquences transformant une onde sphérique en une onde plane. Il est constitué par un système focalisant du type Pill-Box ou Fromage replié associé par empilement à au moins un second système focalisant illuminé par une source délivrant une onde sphérique.The object of the invention is to produce a radiating element with parallel planes operating in the microwave domain transforming a spherical wave into a plane wave. It consists of a focusing system of the Pill-Box or folded Cheese type associated by stacking with at least one second focusing system illuminated by a source delivering a spherical wave.

L'invention permet d'alimenter une antenne-réseau linéaire sans présenter les inconvénients décrits ci-dessus. Un empilement d'éléments rayonnants selon l'invention permet de constituer un répartiteur hyperfréquence équiphase pour une antenne dalle.The invention makes it possible to feed a linear array antenna without having the drawbacks described above. A stack of radiating elements according to the invention makes it possible to constitute an equiphase microwave distributor for a slab antenna.

D'autres avantages et caractéristiques appa- raitront dans la description qui suit, illustrée par les figures suivantes :

  • - la figure 1, un élément rayonnant à plans parallèles du type Pill-Box ou Fromage replié, selon l'art antérieur,
  • - la figure 2, un élément rayonnant à plans parallèles selon l'invention,
  • - les figures 3 et 4, des répartiteurs hyperfréquences équiphases pour des antennes-réseaux linéaires,
  • - la figure 5, une antenne dalle réalisée suivant l'invention.
Other advantages and characteristics will appear in the following description, illustrated by the following figures:
  • - Figure 1, a radiating element with plans pill-box or folded cheese type parallels, according to the prior art,
  • FIG. 2, a radiating element with parallel planes according to the invention,
  • FIGS. 3 and 4, equiphase microwave distributors for linear array antennas,
  • - Figure 5, a slab antenna produced according to the invention.

La figure 1 représente un élément rayonnant à plans parallèles du type Pill-Box ou Fromage replié classique.FIG. 1 represents a radiating element with parallel planes of the pill-box or classic folded cheese type.

La source d'alimentation 1 de l'antenne est séparée de la partie rayonnante 2 par une cloison 3 entre les parties alimentation 4 et rayonnante 2. En effet, cet élément rayonnant Pill-Box ou Fromage replié est constituée par deux Pill-Box ou deux "Fromages" élémentaires couplés par une fente 5 qui court tout le long du fond réflecteur cylindro-parabolique 6. La partie 4 de l'élément replié est excitée par la source 7, un cornet par exemple. La fente 5 est dimensionnée pour que l'ensemble formé par elle et les deux fromages 2 et 4 soit un guide replié adapté. Ce système donne surtout de bons résultats avec un mode TEM.The power source 1 of the antenna is separated from the radiating part 2 by a partition 3 between the power supply 4 and radiating parts 2. In fact, this radiating element Pill-Box or Folded Cheese consists of two Pill-Boxes or two elementary "cheeses" coupled by a slot 5 which runs all along the cylindro-parabolic reflective bottom 6. The part 4 of the folded element is excited by the source 7, a horn for example. The slot 5 is dimensioned so that the assembly formed by it and the two cheeses 2 and 4 is a suitable folded guide. This system above all gives good results with a TEM mode.

Le fait que l'onde sphérique délivrée par le cornet 1 soit directement transformée en onde plane au moyen du réflecteur cylindro-parabolique 2 entraîne nécessairement une profondeur importante de l'élément Pill-Box replié.The fact that the spherical wave delivered by the horn 1 is directly transformed into a plane wave by means of the cylindro-parabolic reflector 2 necessarily results in a significant depth of the folded Pill-Box element.

L'objet de l'invention est un élément rayonnant à plans parallèles transformant une onde sphérique en une onde plane, présentant un encombrement en hauteur et en profondeur beaucoup plus petit que l'encombrement en longueur. La figure 2 montre un exemple non limitatif de l'élément rayonnant à plans parallèles selon l'invention. Il est constitué par une succession d'au moins deux systèmes focalisants, dont le premier 7 est illuminé par une source 8, un cornet par exemple, délivrant une onde sphérique, . ayant par exemple une loi d'amplitude gaussienne et une loi de phase quadratique.Ce premier système focalisant 7 est constitué par deux éléments rayonnants à plans parallèles 91 et 92 du type Pill-Box ou Fromage couplés entre eux par une fente 10 qui court tout le long d'un fond cylindro-hyperbolique réflecteur 11 qui leur est commun. L'onde sphérique émise par la source 8 se réfléchit sur le miroir à profil hyperbolique 11,-dont la courbure ainsi que celles des réflecteurs cylindro-hyperboliques des systèmes focalisants suivants,12 par exemple,est faible, ne modifiant, à chaque réflexion, que légèrement la courbure de l'onde incidente. Les différents systèmes focalisants successifs en nombre relativement important réalisés de la même manière que le premier, sont constitués par des réflecteurs peu courbes, ce qui permet d'obtenir un encombrement en profondeur assez faible. Le dernier système focalisant 13 est constitué par deux éléments 131 et 132 du type Pill-Box ou Fromage couplés entre eux par une fente 14 courant tout le long d'un réflecteur cylindro-parabolique 15 qui transforme l'onde en une onde plane.The object of the invention is a radiating element with parallel planes transforming a spherical wave into a plane wave, having a footprint in height and in depth much smaller than the overall length. FIG. 2 shows a nonlimiting example of the radiating element with parallel planes according to the invention. It consists of a succession of at least two focusing systems, the first 7 of which is illuminated by a source 8, a horn for example, delivering a spherical wave,. having for example a law of Gaussian amplitude and a law of quadratic phase. This first focusing system 7 is constituted by two radiating elements with parallel planes 9 1 and 9 2 of the Pill-Box or Cheese type coupled together by a slit 10 which runs all along a cylindro-hyperbolic reflective bottom 11 which is common to them. The spherical wave emitted by the source 8 is reflected on the mirror with hyperbolic profile 11, -whose curvature as well as those of the cylindro-hyperbolic reflectors of the following focusing systems, for example 12, is weak, not modifying, with each reflection, only slightly the curvature of the incident wave. The various successive focusing systems in relatively large number produced in the same manner as the first, are constituted by slightly curved reflectors, which makes it possible to obtain a relatively small overall depth. The last focusing system 13 is constituted by two elements 13 1 and 13 2 of the Pill-Box or Cheese type coupled together by a slot 14 running all along a cylindro-parabolic reflector 15 which transforms the wave into a plane wave .

Au niveau des fentes 10 par exemple placées devant les fonds réflecteurs 11, les éléments du type Pill-Box ou Fromage 91 et 92 sont reliés entre eux par un couplage directifs, dû à la forme de la fente ou bien réalisé au moyen de sondes.At the level of the slots 10, for example placed in front of the reflective bottoms 11, the elements of the Pill-Box or Cheese type 9 1 and 9 2 are connected together by directional coupling, due to the shape of the slot or else produced by means of probes.

Sur la figure 2, l'élément rayonnant selon l'invention est doté, en sortie, d'un cornet à flanges 16, permettant d'obtenir un diagramme de rayonnement plus sectoral en augmentant sa directivité. Dans ce cas, l'invention permet de réaliser une antenne rayonnant une onde équiphase.In FIG. 2, the radiating element according to the invention is provided, at the outlet, with a flange horn 16, making it possible to obtain a more sectoral radiation diagram by increasing its directivity. In this case, the invention makes it possible to produce an antenna radiating an equiphase wave.

Mais l'invention peut également être utilisable comme répartiteur pour une antenne-réseau linéaire, comme le montre la figure 3. L'ouverture 17 du dernier système focalisant 18 est fermée par un réseau linéaire de fentes 19 dont la plus grande dimension est perpendiculaire au plan de polarisation de l'onde incidente.However, the invention can also be used as a distributor for a linear array antenna, as shown in FIG. 3. The opening 17 of the last focusing system 18 is closed by a linear array of slots 19, the largest dimension of which is perpendicular to the polarization plane of the incident wave.

On peut également mettre, à la place des fentes, en sortie du dernier système focalisant 20 un réseau linéaire de dipôles 21 dont la direction des brins 22 est parallèle au plan de polarisation de l'onde incidente, comme le montre la figure 4. Dans certains cas de réalisation, on peut associer un déphaseur à chacun des dipôles, déphaseur que l'on place entre la sortie du répartiteur et l'alimentation des dipôles. Un élément rayonnant à plans parallèles suivant l'invention, comme décrit précédemment, peut réaliser un répartiteur pour antenne de radar monopulse à condition que la source soit un cornet à deux voies permettant d'obtenir une voie somme et une voie différence.It is also possible to put, in place of the slots, at the output of the last focusing system 20 a linear network of dipoles 21 whose direction of the strands 22 is parallel to the plane of polarization of the incident wave, as shown in FIG. 4. in certain embodiments, it is possible to associate a phase shifter with each of the dipoles, phase shifter which is placed between the output of the distributor and the supply of the dipoles. A radiating element with parallel planes according to the invention, as described above, can produce a distributor for a monopulse radar antenna provided that the source is a two-channel horn enabling a sum channel and a difference channel to be obtained.

Une application intéressante de l'invention est la réalisation d'une antenne réseau plan ou antenne-dalle. Un empilement d'éléments rayonnants suivant l'invention permet d'obtenir une antenne dalle 23, l'alimentation se faisant par un guide d'ondes à fentes 24 par exemple, comme le montre la figure 5. L'utilisation de déphaseurs entre l'alimentation 25 et la dalle 23 permet d'obtenir un balayage électronique du volume d'exploitation du radar par le faisceau rayonné par l'antenne associé à l'écartométrie dans les plans horizontal et vertical. Ces antennes dalles présentent l'avantage d'être très plates.An interesting application of the invention is the production of a flat array antenna or panel antenna. A stack of radiating elements according to the invention makes it possible to obtain a slab antenna 23, the power being supplied by a slot wave guide 24 for example, as shown in FIG. 5. The use of phase shifters between the 'ali 25 and slab 23 provides an electronic scan of the operating volume of the radar by the beam radiated by the antenna associated with the deviation in the horizontal and vertical planes. These slab antennas have the advantage of being very flat.
