Description

La présente invention se rapporte, d'une manière générale, à une antenne omnidirectionnelle multibande pour la transmission et/ou la réception de signaux audio et/ou vidéo.The present invention relates, in general, to an omnidirectional multiband antenna for transmitting and / or receiving audio and / or video signals.

Plus précisément, l'invention concerne une antenne omnidirectionnelle multibande pour la transmission et/ou la réception de signaux audio et/ou vidéo, du genre comprenant des éléments d'antenne identiques interconnectés en un ensemble, chaque élément d'antenne comprenant un élément rayonnant, en polarisation rectiligne verticale, formé de deux quadrilatères réunis par un sommet commun et muni d'un centre d'alimentation radio électrique ainsi qu'un réflecteur associé à cet élément rayonnant de manière que chaque centre d'alimentation se trouve sur un cercle commun et que les centres d'alimentation de deux éléments rayonnants adjacents soient séparés d'une longueur d'onde λ de travail.More specifically, the invention relates to an omnidirectional multiband antenna for transmitting and / or receiving audio and / or video signals, of the kind comprising identical antenna elements interconnected in a set, each antenna element comprising a radiating element in vertical rectilinear polarization, formed by two quadrilaterals united by a common vertex and provided with a radio power supply center and a reflector associated with this radiating element so that each feeding center is on a common circle and that the feed centers of two adjacent radiating elements are separated by a working wavelength λ.

Le Wi-Fi (Wireless Fidelity) est une technologie de transmission de données sans fil destinée à fonctionner en réseau interne. Concrètement le Wi-Fi utilise une bande de fréquence étroite de l'ordre de 2,4 GHz partagée avec d'autres colocataires et permet de relier des ordinateurs portables, des machines de bureau, des objets communiquants ou autres sur un rayon de plusieurs dizaines de mètres en intérieur ou sur plusieurs centaines de mètres dans un environnement ouvert.Wi-Fi ( Wireless Fidelity ) is a wireless data transmission technology designed to operate as an internal network. Specifically, Wi-Fi uses a narrow frequency band of the order of 2.4 GHz shared with other roommates and allows to connect laptops, office machines, communicating objects or others on a radius of several tens meters in indoor or several hundred meters in an open environment.

Par contre le Wimax (Worlwide Interoperability for Microwave Access) a pour objectif de fournir une connexion de transmission de données à haut débit (Internet), de téléphoner ou encore d'interconnecter, de manière confidentielle, des réseaux d'entreprise sur une zone de couverture de plusieurs kilomètres de rayon (12 à 15 km en conditions optimales) tout en permettant de couvrir des zones blanches ou non couvertes par l'ADSL. La réception du signal radio, qui passe sur la bande de fréquences des 3,5 GHz mais qui pourrait opérer sur des fréquences comprises entre 2 et 11 GHz, nécessite l'utilisation d'une antenne orientée vers une station de base. Cette antenne permet de recevoir mais aussi d'émettre en Wimax.Wimax ( Worlwide Interoperability for Microwave Access ), on the other hand, aims to provide a high-speed data connection (Internet), to telephone or to interconnect, confidential, corporate networks over a coverage area of several kilometers radius (12 to 15 km in optimal conditions) while allowing coverage of white areas or areas not covered by ADSL. The reception of the radio signal, which passes over the frequency band of 3.5 GHz but which could operate on frequencies between 2 and 11 GHz, requires the use of an antenna directed towards a base station. This antenna can receive but also emit Wimax.

Toutefois, les antennes disponibles dans le commerce sont, en général, réservées uniquement à l'une de ces technologies. Par conséquent, la mise en place d'un réseau Wi-Fi et d'une connexion Wimax nécessite l'utilisation de deux antennes différentes ce qui augmente le coût d'investissement.However, commercially available antennas are generally reserved for only one of these technologies. Therefore, the establishment of a Wi-Fi network and a Wimax connection requires the use of two different antennas which increases the investment cost.

La présente invention a pour but de proposer une antenne omnidirectionnelle du genre indiqué précédemment qui, tout en étant simple dans sa réalisation et d'un coût non prohibitif, est utilisable aussi bien dans la bande Wi-Fi que dans la bande Wimax de manière à pallier l'inconvénient de l'état de la technique.The object of the present invention is to propose an omnidirectional antenna of the kind indicated above which, while being simple in its implementation and of a non prohibitive cost, can be used both in the Wi-Fi band and in the Wimax band so as to overcome the disadvantage of the state of the art.

Pour atteindre ce but, l'antenne selon l'invention, du genre indiqué précédemment, est caractérisée en ce qu'elle comprend au moins deux tels ensembles d'éléments d'antenne interconnectés, en sorte que cette antenne résonne selon une bande passante et selon des harmoniques de celle-ci.To achieve this goal, the antenna according to the invention, of the type indicated above, is characterized in that it comprises at least two such sets of interconnected antenna elements, so that this antenna resonates in a bandwidth and according to harmonics of this one.

Selon un mode de réalisation particulier l'antenne selon l'invention comprend deux ensembles d'éléments d'antenne interconnectés tels que décrits précédemment.According to a particular embodiment, the antenna according to the invention comprises two sets of interconnected antenna elements as described above.

En outre, selon un mode de réalisation supplémentaire, chaque ensemble comprend un nombre identique d'éléments d'antenne habituellement de 2 à 8, en particulier de 2 à 4 et, de préférence, 4 éléments d'antenne interconnectés.Furthermore, according to a further embodiment, each set comprises an identical number of antenna elements usually from 2 to 8, in particular from 2 to 4 and, preferably, 4 interconnected antenna elements.

Avantageusement, le centre d'alimentation de chaque élément rayonnant faisant partie d'un élément d'antenne d'un ensemble se trouve inscrit sur un cercle commun et équidistant des deux centres d'alimentation qui lui sont adjacents. Par conséquent, lorsque l'ensemble en question comprend quatre éléments d'antenne interconnectés, par conséquent quatre éléments rayonnants, les centres d'alimentation de ces éléments rayonnants sont disposés sur un cercle commun à l'intersection de deux diamètres orthogonaux.Advantageously, the supply center of each radiating element forming part of an antenna element of an assembly is located on a common circle and equidistant from the two feeding centers which are adjacent thereto. Therefore, when the assembly in question comprises four interconnected antenna elements, therefore four radiating elements, the feed centers of these radiating elements are arranged on a common circle at the intersection of two orthogonal diameters.

Selon une autre caractéristique de l'invention, chaque ensemble d'éléments d'antenne interconnectés comprend un élément rayonnant dont le centre d'alimentation se trouve aligné sur une même droite avec le centre d'alimentation d'un élément rayonnant compris dans chacun des autres ensembles d'éléments d'antenne interconnectés formant ainsi des groupes d'éléments rayonnants.According to another characteristic of the invention, each set of interconnected antenna elements comprises a radiating element whose center of supply is aligned on the same line with the center of supply of a radiating element included in each of the other sets of interconnected antenna elements thus forming groups of radiating elements.

Les éléments rayonnants de chacun de ces groupes sont coplanaires et séparés en sorte que chaque côté des quadrilatères d'un élément rayonnant est parallèle au côté correspondant du ou des autres éléments rayonnants du groupe, les centres d'alimentation respectifs étant alignés selon une droite ne coupant aucun quadrilatère.The radiating elements of each of these groups are coplanar and separated so that each side of the quadrilaterals of a radiating element is parallel to the corresponding side of the other radiating element (s) of the group, the respective supply centers being aligned along a straight line. cutting no quadrilateral.

En outre, en vue d'enregistrer les meilleures performances de l'antenne, les centres d'alimentation d'un même groupe d'éléments rayonnants sont éloignés les uns des autres de manière suffisante et appropriée pour éviter un maximum d'interférences. A cette fin, et selon une caractéristique supplémentaire de l'invention, deux centres d'alimentation adjacents d'un groupe d'éléments rayonnants sont éloignés l'un de l'autre d'une distance sensiblement égale à 2λ/3.In addition, in order to record the best performance of the antenna, the power centers of the same group of radiating elements are distant from each other sufficiently and appropriately to avoid a maximum of interference. To this end, and according to a further feature of the invention, two adjacent feed centers of a group of radiating elements are spaced from each other by a distance substantially equal to 2λ / 3.

Avantageusement, chaque ensemble comprend des éléments d'antenne qui comprennent eux-mêmes chacun un élément rayonnant ou radiateur constitué d'une double boucle continue prenant la forme géométrique de deux carrés avec un sommet commun, situés dans un même plan et dont le périmètre est sensiblement égal à deux longueurs d'onde (2 λ).Advantageously, each set comprises antenna elements which each comprise a radiating element or radiator consisting of a double continuous loop taking the geometric form of two squares with a common vertex, situated in the same plane and whose perimeter is substantially equal to two wavelengths (2 λ).

Un tel élément rayonnant pourra être désigné par la suite aussi bien dans la description que dans les revendications par la dénomination « biquad ».Such a radiating element may be designated later in the description as in the claims by the name "biquad".

Cet élément rayonnant est réalisé habituellement à partir d'un fil métallique, avantageusement le cuivre, disposé à faible distance du réflecteur auquel il est fixé. Toutefois, selon une mise en oeuvre préférée de l'invention, ce fil métallique est remplacé par un circuit imprimé sur un panneau support diélectrique ou isolant, l'impression étant réalisée selon des méthodes connues. Ce panneau support est habituellement constitué d'un panneau stratifié formé d'un composite époxy renforcé de fibres de verre. Un tel panneau est en général de faible épaisseur, de préférence inférieure à 2 mm. Habituellement, un panneau support unique est utilisé pour l'impression des éléments rayonnants d'un groupe.This radiating element is usually made from a wire, advantageously copper, disposed at a small distance from the reflector to which it is attached. However, according to a preferred embodiment of the invention, this wire is replaced by a printed circuit on a dielectric or insulating support panel, the printing being carried out according to known methods. This support panel is usually made of a laminated panel formed of a fiberglass reinforced epoxy composite. Such a panel is generally thin, preferably less than 2 mm. Usually, a single support panel is used to print the radiating elements of a group.

Les différents éléments rayonnants d'un même ensemble sont reliés via leurs centres d'alimentation respectifs à un coupleur par l'intermédiaire d'un câble coaxial d'alimentation en énergie.The different radiating elements of the same assembly are connected via their respective power centers to a coupler via a coaxial power supply cable.

Généralement, l'interconnexion des éléments rayonnants appartenant à un ensemble peut comprendre de 2 à 8, en particulier de 2 à 4 et de préférence 4 éléments rayonnants tels que décrits ci-dessus.Generally, the interconnection of the radiating elements belonging to a set may comprise from 2 to 8, in particular from 2 to 4 and preferably 4 radiating elements as described above.

La distance comprise entre le centre d'alimentation d'un élément rayonnant d'un groupe et son réflecteur étant la même pour chacun des biquads constitutifs de ce groupe, les différents réflecteurs des différents biquads en question sont fusionnés par leurs bords en un réflecteur continu formant ainsi un réflecteur unique.The distance between the supply center of a radiating element of a group and its reflector being the same for each of the constituent biquads of this group, the different reflectors of the different biquads in question are merged by their edges into a continuous reflector thus forming a single reflector.

Celui-ci prend habituellement la forme d'un seul panneau configuré en support direct de ces biquads ou en support du panneau diélectrique sur lequel les biquads sont imprimés.This usually takes the form of a single panel configured in direct support of these biquads or in support of the dielectric panel on which the biquads are printed.

Ainsi, selon une autre caractéristique de l'invention, les éléments rayonnants d'un même groupe sont associés à un réflecteur unique formant panneau support pour ce groupe d'éléments rayonnants.Thus, according to another characteristic of the invention, the radiating elements of the same group are associated with a single reflector forming a support panel for this group of radiating elements.

Ce réflecteur est formé d'une plaque métallique généralement en cuivre ou en aluminium. L'acier, en particulier l'acier inoxydable ou encore le polychlorobiphényle (« PCB ») peuvent être utilisés également. Dans ce cas, et de manière connue, il peut être avantageux de braser un métal conducteur électrique, par exemple du cuivre, à l'orifice du canal coaxial, orifice ménagé dans ce réflecteur, de manière à assurer une bonne connexion physique et électrique.This reflector is formed of a metal plate generally made of copper or aluminum. Steel, especially stainless steel or polychlorinated biphenyl ("PCB") can be used as well. In this case, and in known manner, it may be advantageous to solder an electrically conductive metal, for example copper, to the orifice of the coaxial channel orifice provided in this reflector, so as to ensure a good physical and electrical connection.

Les ensembles d'éléments d'antenne interconnectés ainsi constitués seront reliés par l'intermédiaire des coupleurs des éléments rayonnants de chaque ensemble. Cette interconnexion, de même d'ailleurs que l'interconnexion des éléments rayonnants d'un ensemble d'éléments d'antenne et que le modèle de tracé des différents biquads, pourra être effectuée après étude des caractéristiques souhaitées de rayonnement. Cette étude peut être réalisée sur base d'un fichier informatique préalablement conçu par une technologie de simulation par ordinateur faisant appel à un logiciel disponible dans le commerce, par exemple le logiciel CST Studio Suite 2009.The sets of interconnected antenna elements thus formed will be connected through the couplers of the radiating elements of each set. This interconnection, as well as the interconnection of the radiating elements of a set of antenna elements and the tracing pattern of the different biquads, may be performed after studying the desired characteristics of radiation. This study can be carried out on the basis of a computer file previously designed by a computer simulation technology using commercially available software, for example the CST Studio Suite 2009 software.

Selon un mode de réalisation particulier et préféré, l'antenne selon l'invention comprend un couplage de deux ensembles d'éléments d'antenne comprenant chacun quatre éléments rayonnants interconnectés associés chacun à un réflecteur.According to a particular and preferred embodiment, the antenna according to the invention comprises a coupling of two sets of antenna elements each comprising four interconnected radiating elements each associated with a reflector.

En conséquence, selon une autre de ses caractéristiques, l'antenne selon l'invention comprend un couplage de deux ensembles d'éléments d'antenne comprenant chacun quatre éléments rayonnants interconnectés associés chacun à un réflecteur.Consequently, according to another of its characteristics, the antenna according to the invention comprises a coupling of two sets of antenna elements each comprising four interconnected radiating elements each associated with a reflector.

L'invention sera mieux comprise et d'autres buts, caractéristiques et avantages de celle-ci apparaîtront plus clairement au cours de la description explicative qui va suivre en référence aux dessins annexés donnés uniquement à titre d'exemple illustrant un mode de réalisation de l'invention et dans lesquels :

  • la figure 1 est une vie schématique frontale d'une antenne selon l'invention,
  • la figure 2 est une vue en coupe frontale de l'antenne à la figure 1,
  • la figure 3 est une vue en plan de l'antenne à la figure 1,
The invention will be better understood and other objects, features and advantages thereof will appear more clearly in the following explanatory description with reference to the accompanying drawings given solely by way of example illustrating an embodiment of the invention. invention and in which:
  • the figure 1 is a schematic frontal life of an antenna according to the invention,
  • the figure 2 is a frontal sectional view of the antenna at the figure 1 ,
  • the figure 3 is a plan view of the antenna at the figure 1 ,

Tel que représentée aux figures 1 à 3, l'antenne selon l'invention comprend un premier ensemble d'éléments d'antenne ou "ensemble inférieur" formé de quatre éléments rayonnants 1 de type biquad fixés sur un support isolant 2 et dont les centres d'alimentation 3 sont situés sensiblement dans un même plan ainsi qu'un second ensemble d'éléments d'antenne ou "ensemble supérieur" formé de quatre éléments rayonnants la également de type biquad fixés sur un support isolant 2a et dont les centres d'alimentation 3a sont également situés dans un même plan.As represented in Figures 1 to 3 , the antenna according to the invention comprises a first set of antenna elements or "lower set" formed of four biquad-type radiating elements 1 fixed on an insulating support 2 and whose feed centers 3 are located substantially in a same plane and a second set of antenna elements or "upper assembly" formed of four radiating elements also biquad type fixed on an insulating support 2a and whose feed centers 3a are also located in the same plan.

D'autre part, les quatre centres d'alimentation 3 se trouvent sur un cercle commun C et aux points d'intersection, avec ce cercle, de deux diamètres orthogonaux de même que les quatre centres 3a sont également disposés sur un cercle commun et également situés aux points d'intersection, avec ce cercle, de deux diamètres orthogonaux. Dans les deux cas, la corde qui sous-tend l'arc situé entre deux centres d'alimentation 3 adjacents ou entre deux centres d'alimentation 3a adjacents est égale à une longueur d'onde λ. Par ailleurs, on observe que les biquads de chaque ensemble sont tangents au cercle commun passant par leurs centres d'alimentation.On the other hand, the four feeding centers 3 are located on a common circle C and at the points of intersection, with this circle, of two orthogonal diameters as well as the four centers 3a are also arranged on a common circle and also located at the points of intersection, with this circle, of two orthogonal diameters. In both cases, the rope underlying the arc located between two adjacent feed centers 3 or between two adjacent feed centers 3a is equal to a wavelength λ. Moreover, we observe that the biquads of each set are tangent to the common circle passing through their feeding centers.

Les éléments rayonnants 1 de l'ensemble inférieur et les éléments rayonnants la de l'ensemble supérieur forment, lorsqu'ils sont pris ensemble, quatre groupes d'éléments rayonnants 1 ; 1a, chaque groupe étant disposé sur un support isolant unique provenant en fait de la fusion d'un support isolant 2 avec un support isolant 2a. D'autre part, les centres d'alimentation de deux éléments rayonnants adjacents d'un même groupe sont isolés les uns des autres d'une distance équivalant à 2λ/3.The radiating elements 1 of the lower assembly and the radiating elements 1a of the upper assembly form, when taken together, four groups of radiating elements 1; 1a, each group being arranged on a single insulating support resulting in fact from the melting of an insulating support 2 with an insulating support 2a. On the other hand, the feed centers of two adjacent radiating elements of the same group are isolated from each other by a distance equivalent to 2λ / 3.

Ces éléments rayonnants biquads 1 et 1a se présentent sous la forme de circuits, correspondant à des pistes en cuivre, imprimés sur le support isolant unique 2 ; 2a en verre époxy de type FR4.These biquads radiating elements 1 and 1a are in the form of circuits, corresponding to copper tracks, printed on the single insulating support 2; 2a FR4 type epoxy glass.

D'autre part, chaque support isolant 2 ; 2a est lui-même fixé, à une distance précise et au moyen d'isolateurs 4, en nylon ou téflon, à un réflecteur 5 constitué d'une plaque en aluminium de type AG4MC. Les quatre plaques 5 métalliques fixées à une plaque de base 6 en aluminium ou en fibre de verre forment ainsi la structure de base de l'antenne selon l'invention laquelle est recouverte d'une coiffe 7 destinée à renforcer cette structure.On the other hand, each insulating support 2; 2a is itself fixed, at a precise distance and by means of insulators 4, nylon or teflon, a reflector 5 consists of an aluminum plate AG4MC type. The four metal plates 5 attached to a base plate 6 of aluminum or fiberglass thus form the basic structure of the antenna according to the invention which is covered with a cap 7 for reinforcing this structure.

Les figures 2 et 3 montrent également que les éléments rayonnants de chaque ensemble sont reliés entre eux au moyen de coupleurs à quatre voies indiqués respectivement 8 et 8a, ces deux coupleurs étant eux-mêmes interconnectés par l'intermédiaire du coupleur 9 à deux voies. On observe en outre que la sortie de ce coupleur à deux voies est également reliée à un éclateur parafoudre 10 calibré à 2,46 Mhz lui-même connecté à la masse.The Figures 2 and 3 also show that the radiating elements of each set are interconnected by means of four-way couplers indicated respectively 8 and 8a, these two couplers themselves being interconnected via the two-way coupler 9. It is further observed that the output of this two-way coupler is also connected to a spark arrester 10 calibrated at 2.46 Mhz itself connected to ground.

Selon un mode de réalisation, l'antenne selon l'invention est fabriquée en soudant d'abord un connecteur de type SMA/KYB3 au niveau de centre d'alimentation de chaque élément biquad après avoir préalablement percé les supports isolants 2; 2a. A cet effet, on utilise des câbles coaxiaux préfabriqués se terminant par un brin de cuivre soudé latéralement sur la masse lequel doit légèrement dépasser à son extrémité.According to one embodiment, the antenna according to the invention is manufactured by first welding an SMA / KYB3 type connector at the feed center of each biquad element after having previously pierced the insulating supports 2; 2a. For this purpose, prefabricated coaxial cables ending in a copper strand welded laterally to the ground, which must slightly protrude at its end, are used.

Après cette opération, on assemble les quatre supports isolants 2; 2a porteurs des éléments rayonnants 1 sous forme de circuits imprimés et ce, sur les faces respectives des quatre plaques 5 métalliques par l'intermédiaire d'isolateurs 4, de vis taraudées et d'écrous en nylon.After this operation, the four insulating supports 2 are assembled; 2a carriers of the radiating elements 1 in the form of printed circuits and on the respective faces of the four metal plates by means of insulators 4, threaded screws and nylon nuts.

Par la suite, on assemble deux des quatre réflecteurs 5 sur la plaque de base 6, en l'occurrence deux réflecteurs opposés. On insère les coupleurs à quatre voies que l'on raccorde aux connecteurs des différents éléments rayonnants associés aux deux plaques 5 en question, à savoir le coupleur 8 aux éléments rayonnants 1, le coupleur 8a aux éléments rayonnants 1a et on raccorde le coupleur 9 à deux voies aux deux coupleurs à quatre voies. On relie ensuite la sortie 11 du coupleur à deux voies à un câble coaxial de sortie d'antenne terminé par un élément SMA femelle que l'on fixe à la plaque de base 6 par l'intermédiaire du parafoudre 10 riveté à celle-ci. On connecte ensuite, aux deux coupleurs à quatre voies, les éléments rayonnants associés aux deux plaques 5 métalliques restantes, en les rivetant à la plaque de base ainsi qu'aux deux premières plaques métalliques. On termine l'assemblage en fixant un capot 12 de consolidation aux quatre réflecteurs 5, en recouvrant cet assemblage d'une coiffe 7 que l'on solidarise à la plaque de base 6 et en posant un joint 13 d'étanchéité.Subsequently, two of the four reflectors 5 are assembled on the base plate 6, in this case two opposite reflectors. The four-way couplers which are connected to the connectors of the different radiating elements associated with the two plates 5 in question are inserted, namely the coupler 8 to the radiating elements 1, the coupler 8a to the radiating elements 1a and the coupler 9 is connected to two channels to two four-way couplers. The output 11 of the two-way coupler is then connected to a coaxial antenna output cable terminated by a female SMA element which is fixed to the base plate 6 via the surge arrester 10 riveted thereto. Then connect to two four-way couplers, the radiating elements associated with the remaining two metal plates, riveting them to the base plate as well as to the first two metal plates. The assembly is completed by fixing a consolidation cover 12 to the four reflectors 5, covering this assembly with a cap 7 which is secured to the base plate 6 and placing a seal 13.

L'antenne selon l'invention s'est révélée utilisable non seulement à 2,4 GHz, pour des applications de type Wi-Fi, mais aussi à 3,5 GHz et 5,9 GHz pour des applications Wimax notamment de type Wimax 1 et Wimax 2. Dans des conditions optimales, par exemple par mer calme, la portée de cette antenne est d'au moins 13 km tandis que dans des conditions d'intempéries extrêmes, telles que fortes chutes de neige, cette portée avoisine les 2 km. D'autre part, sa réalisation facile et surtout son coût très réduit permettent, à l'antenne selon l'invention, de concurrencer valablement une technologie de transmissions de données par fibres optiques du genre ADSL.The antenna according to the invention has proved to be usable not only at 2.4 GHz, for Wi-Fi type applications, but also at 3.5 GHz and 5.9 GHz for Wimax applications, such as Wimax 1 and Wimax 2. Under optimal conditions, for example by calm sea, the range of this antenna is at least 13 km while in extreme weather conditions, such as heavy snow, this range is around 2 km . On the other hand, its easy realization and above all its very low cost allow, on the antenna according to the invention, to validly compete with a fiber optic data transmission technology of the ADSL type.
