Description

DOMAINE TECHNIQUE GENERALGENERAL TECHNICAL FIELD

L'invention concerne le domaine des antennes de traversée de paroi, et plus particulièrement les antennes de traversée de paroi dont la surface rayonnante affleure sur la surface externe d'une paroi d'un appareil portable, volant ou terrestre.The invention relates to the field of wall-pass antennas, and more particularly to wall-pass antennas whose radiating surface is flush with the outer surface of a wall of a portable, flying or land-based device.

ETAT DE LA TECHNIQUESTATE OF THE ART

La figure 1 illustre une antenne de traversée de paroi.The figure 1 illustrates a wall penetration antenna.

Un guide d'onde 2 rayonnant traverse une paroi 3, typiquement celle d'un engin volant, et est excité au moyen d'un boitier 1 d'excitation.A radiating waveguide 2 passes through a wall 3, typically that of a flying machine, and is excited by means of an excitation box 1.

Le boitier 1 d'excitation est conformé pour être agencé le long de la surface interne de la paroi 3.The box 1 of excitation is shaped to be arranged along the inner surface of the wall 3.

Le boitier 1 d'excitation est couplé perpendiculairement au guide d'ondes 2 rayonnant et comprend une prise coaxiale 4 pour l'alimentation de l'antenne.The excitation box 1 is coupled perpendicularly to the radiating waveguide 2 and comprises a coaxial plug 4 for feeding the antenna.

Pour permettre de loger le boitier le long de la surface interne de la paroi 3, ce dernier se présente sous la forme d'un guide d'ondes d'excitation rectangulaire. Le guide d'ondes 2 rayonnant se présente sous la forme d'un guide d'ondes rectangulaire.To accommodate the housing along the inner surface of the wall 3, the latter is in the form of a rectangular excitation waveguide. The radiating waveguide 2 is in the form of a rectangular waveguide.

Ainsi dans cette configuration connue, un guide d'ondes rectangulaire excite un autre guide d'ondes rectangulaire qui agit comme un élément rayonnant.Thus in this known configuration, a rectangular waveguide excites another rectangular waveguide which acts as a radiating element.

Il existe actuellement un besoin de réduire la taille du boitier d'excitation afin de pouvoir loger d'autres équipements à l'intérieur de l'engin tout en ne dégradant pas les performances globales de l'antenne.There is currently a need to reduce the size of the excitation box in order to accommodate other equipment inside the machine while not degrading the overall performance of the antenna.

Une solution connue est de remplir l'intérieur du guide d'ondes d'excitation d'un matériau diélectrique ce qui permet de réduire la taille du guide d'ondes 1 d'excitation. Cette solution n'est toutefois pas optimale du fait des possibles discontinuités de permittivité entre le guide d'excitation et le guide rayonnant qui peuvent dégrader les performances de l'antenne.A known solution is to fill the inside of the excitation waveguide with a dielectric material which makes it possible to reduce the size of the excitation waveguide 1. This solution is however not optimal because of the possible discontinuities of permittivity between the excitation guide and the radiating guide which can degrade the performance of the antenna.

PRESENTATION DE L'INVENTIONPRESENTATION OF THE INVENTION

L'invention répond à ce besoin en proposant une antenne dont l'encombrement est inférieur à celui des solutions connues du même type.The invention responds to this need by providing an antenna whose size is less than that of known solutions of the same type.

Par conséquent, l'invention propose, selon un premier aspect, une antenne de traversée de paroi comprenant :

  • un guide d'ondes rayonnant adapté pour traverser une paroi comportant une surface interne et une surface externe, une extrémité du guide d'ondes rayonnant venant affleurer la surface externe de la paroi ;
  • un guide d'ondes d'excitation adapté pour être couplé au guide d'ondes rayonnant en étant agencé le long de la surface interne de la paroi;
caractérisée en ce que le guide d'onde d'excitation est un guide d'ondes à arête(s).Therefore, according to a first aspect, the invention proposes a wall-traversing antenna comprising:
  • a radiating waveguide adapted to traverse a wall having an inner surface and an outer surface, an end of the radiating waveguide flush with the outer surface of the wall;
  • an excitation waveguide adapted to be coupled to the radiating waveguide by being arranged along the inner surface of the wall;
characterized in that the excitation waveguide is a ridge waveguide (s).

L'invention est avantageusement complétée par les caractéristiques suivantes, prises seules ou en une quelconque de leur combinaison techniquement possible :

  • le guide d'ondes d'excitation comprend une première partie et une seconde partie reliées entre elles par un coude, le guide d'ondes d'excitation étant couplé au guide d'ondes rayonnant par l'intermédiaire de la seconde partie ;
  • le guide d'ondes d'excitation est un guide d'ondes à double arêtes ;

  • le guide d'onde rayonnant est rempli d'un matériau diélectrique ;
  • l'épaisseur du guide d'ondes d'excitation est comprise entre 10 et 20 mm, de préférence 16 mm.
The invention is advantageously completed by the following features, taken alone or in any of their technically possible combination:
  • the excitation waveguide comprises a first portion and a second portion interconnected by a bend, the excitation waveguide being coupled to the radiating waveguide via the second portion;
  • the excitation waveguide is a double-edge waveguide;
  • the radiating waveguide is a waveguide with single or double edge (s);
  • the excitation waveguide comprises one or more adjustment screws disposed on the edge;
  • the excitation waveguide is filled with a dielectric material;
  • the radiating waveguide is filled with a dielectric material;
  • the thickness of the excitation waveguide is between 10 and 20 mm, preferably 16 mm.

Selon un second aspect, l'invention propose également un système d'excitation pour antenne de traversée de paroi comprenant un guide d'ondes rayonnant (20) adapté pour traverser une paroi comportant une surface interne et une surface externe, une extrémité du guide d'ondes rayonnant venant affleurer la surface externe de la paroi, le système d'excitation étant conformé pour pouvoir être agencé le long de la surface interne de la paroi, le système étant caractérisé en ce qu'il accueille un guide d'ondes à arête(s).According to a second aspect, the invention also proposes a wall-pass antenna excitation system comprising a radiating waveguide (20) adapted to pass through a wall having an inner surface and an outer surface, an end of the waveguide radiating wave coming flush with the outer surface of the wall, the excitation system being shaped so as to be arranged along the inner surface of the wall, the system being characterized in that it accommodates a ridge waveguide (s).

Enfin l'invention propose selon un troisième aspect un dispositif portable, volant ou terrestre comprenant une paroi traversée par une antenne selon le premier aspect de l'invention.Finally the invention proposes according to a third aspect a portable device, flying or terrestrial comprising a wall traversed by an antenna according to the first aspect of the invention.

Les avantages de l'invention sont multiples.The advantages of the invention are manifold.

La taille du guide d'ondes d'excitation est telle qu'il est moins encombrant qu'un boitier utilisé dans les antennes du même type connues.The size of the excitation waveguide is such that it is less bulky than a box used in the antennas of the same known type.

La masse de l'antenne est par conséquent réduite ce qui dans le cadre d'une intégration au sein d'un engin volant est avantageux ou encore dans l'intégration dans un équipement portable. Par exemple pour une antenne fonctionnant à 5 GHz la masse est réduire d'un facteur 4 (125g au lieu de 500g).The mass of the antenna is therefore reduced which in the context of integration within a flying machine is advantageous or in the integration in a portable equipment. For example, for an antenna operating at 5 GHz the mass is reduced by a factor of 4 (125 g instead of 500 g).

L'utilisation des vis de réglages permet de configurer le diagramme de l'antenne de manière plus fine que dans les solutions connues.The use of adjustment screws makes it possible to configure the antenna diagram more finely than in known solutions.

Et l'antenne présente l'avantage d'être plus discrète, les discontinuités dans la structure de l'engin volant présentant un contour plus petit que lorsqu'on utilise un boitier de l'art antérieur.And the antenna has the advantage of being more discreet, the discontinuities in the structure of the flying machine having a smaller contour than when using a case of the prior art.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

En référence à la figure 2, l'antenne de traversée de paroi conforme à un mode de réalisation possible de l'invention comprend un guide d'ondes rayonnant 20 adapté pour traverser une paroi 3 comportant une surface interne 31 et une surface externe 32.With reference to the figure 2 , the wall-pass antenna according to a possible embodiment of the invention comprises a radiating waveguide 20 adapted to pass through a wall 3 having an inner surface 31 and an outer surface 32.

Une extrémité 21 du guide d'ondes rayonnant 20 vient affleurer la surface externe 32 de la paroi 3.An end 21 of the radiating waveguide 20 is flush with the outer surface 32 of the wall 3.

L'antenne de traversée de paroi comprend également un guide d'ondes d'excitation 10 couplé au guide d'ondes rayonnant 20 en étant agencé le long de la surface interne 31 de la paroi 3.The wall-traversing antenna also comprises an excitation waveguide 10 coupled to the radiating waveguide 20 being arranged along the inner surface 31 of the wall 3.

Les guides d'ondes d'excitation 10 et de rayonnement ont une forme externe rectangulaire ou circulaire.The excitation waveguides 10 and radiation have a rectangular or circular external shape.

Toutefois, compte tenu des contraintes d'aménagement par rapport à la paroi on préfèrera une forme rectangulaire.However, given the layout constraints relative to the wall, a rectangular shape will be preferred.

Le guide d'onde d'excitation 10 est un guide d'ondes à arête(s) (en anglais, « waveguide ridge »).The excitation waveguide 10 is a waveguide (s) (in English, " waveguide ridge ").

La partie interne du guide d'ondes d'excitation est donc un évidement ayant au moins une arête.The inner part of the excitation waveguide is therefore a recess having at least one edge.

Comparativement à un guide d'ondes dont l'évidement est rectangulaire, le guide d'ondes à arête(s) présente une épaisseur inférieure tout en conservant des performances en termes de rayonnement équivalentes pour les mêmes fréquences de travail.Compared to a waveguide with a rectangular recess, the ridge waveguide (s) has a lower thickness while maintaining equivalent radiation performance for the same working frequencies.

A titre d'exemple, on passe pour une fréquence de travail à 2 GHz d'une épaisseur de l'ordre de 25 mm pour un guide de section rectangulaire à une épaisseur de l'ordre de 16 mm pour un guide à arête(s).For example, we pass for a working frequency at 2 GHz with a thickness of about 25 mm for a rectangular section guide to a thickness of about 16 mm for a ridge guide (s). ).

Dans le cadre de l'invention, l'épaisseur du guide d'ondes d'excitation est comprise entre 10 et 20 mm, de préférence 16 mm.In the context of the invention, the thickness of the excitation waveguide is between 10 and 20 mm, preferably 16 mm.

Les figures 3a et 3b illustrent respectivement une vue de face de l'évidement du guide d'ondes d'excitation à simple arête 40 et à double arêtes 41, 42.The Figures 3a and 3b respectively illustrate a front view of the recess of the single edge 40 and double edge excitation waveguide 41, 42.

Pour coupler le guide d'ondes d'excitation 10 au guide d'ondes rayonnant 20, le guide d'ondes d'excitation 10 comprend un coude 101.To couple the excitation waveguide 10 to the radiating waveguide 20, the excitation waveguide 10 comprises a bend 101.

Ainsi, le guide d'ondes d'excitation 10 comprend une première partie 100 qui se prolonge vers une seconde partie 102 en formant un coude 101.Thus, the excitation waveguide 10 comprises a first portion 100 which extends to a second portion 102 forming a bend 101.

Le coude 101 forme un angle de 45° avec un axe longitudinal de la première partie 101.The bend 101 forms an angle of 45 ° with a longitudinal axis of the first portion 101.

Le couplage entre les deux guides est effectué au moyen de vis (non représenté).The coupling between the two guides is performed by means of screws (not shown).

Le guide d'ondes rayonnant 20 présente une section interne qui peut être rectangulaire et comportant au moins une arête (comme le guide d'ondes d'excitation 10).The radiating waveguide 20 has an inner section which may be rectangular and having at least one edge (such as the excitation waveguide 10).

Le rayonnement est rendu possible par le fait que le guide d'ondes rayonnant comprend une fente (qui est identique à la section interne du guide rayonnant).The radiation is made possible by the fact that the radiating waveguide comprises a slot (which is identical to the inner section of the radiating guide).

En outre, le guide d'ondes rayonnant 20 est configuré pour qu'en fonctionnant l'antenne ait un rayonnement hémisphérique.In addition, the radiating waveguide 20 is configured to operate the antenna to have hemispherical radiation.

Dans un but d'amélioration du couplage du guide d'ondes 10 d'excitation avec le guide d'ondes 20 rayonnant, les sections internes des guides d'ondes d'excitation 10 et rayonnant 20 sont identiques.In order to improve the coupling of the excitation waveguide with the radiating waveguide, the inner sections of the excitation and radiating waveguides 20 are identical.

Ainsi si le guide d'ondes d'excitation 10 est à arête(s) le guide d'ondes de rayonnement 20 est aussi à arête(s).Thus, if the excitation waveguide 10 is at the edge (s), the radiation waveguide 20 is also at an edge (s).

Pour diminuer la taille du guide d'ondes d'excitation 10 l'évidement interne peut être rempli d'un diélectrique présentant une permittivité ε typiquement comprise entre 1 et 6, typiquement égale à 3.To reduce the size of the excitation waveguide 10 the internal recess can be filled with a dielectric having a permittivity ε typically between 1 and 6, typically equal to 3.

Toujours dans une optique de rendre optimal le couplage entre le guide d'ondes d'excitation et le guide d'ondes rayonnant, le guide d'ondes rayonnant pourra aussi être rempli d'un matériau diélectrique, de préférence identique à celui remplissant le guide d'ondes d'excitation.Still with a view to optimizing the coupling between the excitation waveguide and the radiating waveguide, the radiating waveguide may also be filled with a dielectric material, preferably identical to that filling the guide. of excitation waves.

Comme on l'aura compris, le guide d'ondes rayonnant est identique au guide d'ondes d'excitation pour améliorer le couplage des deux guides.As will be understood, the radiating waveguide is identical to the excitation waveguide to improve the coupling of the two guides.

Pour assurer une reconfigurabilité du diagramme de rayonnement de l'antenne, on peut prévoir des vis 50 de réglages disposés sur une arête du guide d'ondes d'excitation les unes derrière les autres dans le sens longitudinal du guide d'excitation. De telles vis de réglages permettent d'introduire des éléments parasites qui permettent d'optimiser le transfert d'énergie dans la bande de fréquences de l'antenne.To ensure reconfigurability of the radiation pattern of the antenna, adjustment screws 50 may be provided on one edge of the excitation waveguide one behind the other in the longitudinal direction of the excitation guide. Such adjustment screws make it possible to introduce parasitic elements which make it possible to optimize the energy transfer in the frequency band of the antenna.

L'antenne ci-dessus décrite est adaptée pour être intégrée dans un dispositif portable, volant ou terrestre comprenant une paroi qui est traversée par l'antenne.The antenna described above is adapted to be integrated in a portable device, flying or terrestrial comprising a wall which is traversed by the antenna.
