Definitions
- the invention relates to an active antenna panel with a multilayer structure.
- It aims in particular but not limited to antenna systems active for satellite intended to manage one or more beams by a single panel of radiating elements, via a beam distributor with structure multilayer.
- these distributors are built on a horizontal stacking model layers (parallel to the plane of the antenna, which creates significant constraints on the performance (generally narrow band) and the size of the interconnection with the radiating elements, then arranged perpendicularly to the dispatcher.
- the invention therefore aims to overcome the drawbacks mentioned above.
- the invention provides an active antenna panel having a main plane and comprising a network of n radiating elements and a distributor m bundles with a multilayer structure intended to supply the n elements radiant, the distributor comprising first so-called formation layers intended to support means for forming beams, and second so-called connection layers intended to support first means of electrical connection of the first layers to each other and of the second means of electrical connection to the radiating elements.
- This vertical multilayer topology in molded technology allows the reuse of the coplanar three-dimensional RF interconnection by one of the connection layers, the only known transition technique today high-performance, broadband three-dimensional. It allows you to target a wide panel of applications without variation of concepts or technologies.
- the monoblock is a plane parallelepiped, the connection layers extending substantially parallel to the plane of the antenna and comprising a front connection layer comprising the second means of connection and a rear connection layer comprising the first means of connection, the radiating elements being attached directly to said layer front connection.
- the three-dimensional RF interconnection routing then becomes simplistic and easier to optimize.
- the same surface is available as in multilayer horizontal for signal routing;
- Figure 1a is a schematic perspective representation of a active antenna panel according to the invention in which the radiating elements do not are not reported.
- Figure 1b is a schematic perspective representation of the panel active antenna of Figure 1a in which the radiating elements are attached.
- Figure 2a is an exploded and more detailed schematic representation of the active antenna panel of Figures 1a and 1b.
- Figure 2b is a schematic representation of the panel in Figure 2a after molding the different layers.
- Figures 3a, b and c are schematic representations of the different layers for forming an active antenna panel according to the invention.
- Figure 4a and b are schematic representations of different modes for making the connection layers of an active antenna panel according to the invention.
- FIG. 5 is an electrical diagram of the various functions implemented in the beam splitter of an antenna panel according to the invention.
- the active antenna panel 1 comprises a network of radiating elements 2 and a beam splitter 3.
- the array of radiating elements 2 comprises 64 radiating elements 2i distributed over an 8 ⁇ 8 matrix. These elements 2i radiators are made in a three-dimensional technology known from the skilled person. It will therefore not be described in more detail.
- the beam splitter 3 is intended to supply the elements radiating 2i from m beams, m being an integer greater than or equal to 1. In the embodiment shown in FIG. 2a, m is equal to 6.
- connection means are supported by so-called second layers connection 8.
- the formation layers 6 and the connection layers 8 are assembled by molding so that the beam splitter constitutes a monoblock 9, the formation layers 6 extending substantially perpendicular to the main plane P of the antenna.
- the monoblock 9 is a planar parallelepiped with two large faces 10 and 11 whose area corresponds to that of the matrix of radiating elements 2i.
- connection layers 8 have a front connection layer 8a comprising the second connection means 7b and a rear connection layer 8b comprising the first connection means 7a, the radiating elements 2i being attached directly to said layer of front connection 8a.
- the various training means 5a, 5b, 5c are achievable using any technology accessible to the skilled person such as by example the multilayer microwave frequency PCB (Print Circuit Board) technology.
- PCB Print Circuit Board
- connection circuits 7a and 7b It is the same for the connection circuits 7a and 7b.

Abstract
Description
- le routage devient alors plus dense et donc plus difficile, notamment pour assurer des chemins électriques identiques à tous les signaux; les pertes augmentant inévitablement ;
- la présence de plusieurs faisceaux oblige à gérer la loi (amplitude; phase) d'illumination de chaque pinceau au sein-même du répartiteur, entre les fonctions de division et de recombinaison, l'intégration de puces (atténuateur; déphaseur) dans le répartiteur s'avérant alors nécessaire.
- dès que la fréquence d'utilisation dépasse 20 Ghz. Dans ce cas les techniques d'interconnexion multicouche RF utilisables dans cette technologie (trou métallisé notamment) sont limitées par l'état de l'art actuel ;
- pour l'intégration de puces à l'intérieur-même du répartiteur puisque le procédé de réalisation des multicouches PCB (laminage, pression, thermofusion) est généralement incompatible avec tout composant de relief que l'on souhaite insérer dans le multicouche. Cet inconvénient oblige à déporter les puces à l'extérieur du répartiteur.
- les couches de formation s'étendent sensiblement perpendiculairement au plan principal de l'antenne ;
- les couches de formation et les couches de connexion sont assemblées par moulage de telle sorte que le répartiteur de faisceaux constitue un monobloc. ;
- les éléments rayonnants sont connectés directement aux seconds moyens de connexion.
- division de puissance des m sources de signal RF ( non représentées) ;
- traitement en phase et en amplitude de la puissance divisée de manière à générer, ou niveau des éléments rayonnants 2i, le dépointage souhaité ; et
- recombinaison après le traitement en phase et en amplitude de manière à alimenter les éléments rayonnants 2i pour obtenir ledit dépointage souhaité.
- connexion des moyens de division de puissance 5a vers les sources de signaux RF ;
- connexion des différents niveaux de division de puissance entre eux ;
- connexion des moyens de division de puissance 5a aux moyens de traitement 5b ;
- connexion des moyens de traitement 5b aux moyens de recombinaison 5c ;
- connexion des différents niveaux de recombinaison entre eux ; et
- connexion des moyens de recombinaison 5c aux éléments rayonnants 2i.
- des premiers moyens de connexion 7a réalisant les connexions des moyens de division de puissance 5a vers les sources de signaux RF, les connexions des différents niveaux de division de puissance entre eux et les connexions des moyens de division de puissance 5a aux moyens de traitement 5b ; et
- des seconds moyens de connexions 7b réalisant les connexions des moyens de traitement 5b aux moyens de recombinaison 5c , les connexions des différents niveaux de recombinaison entre eux et les connexions des moyens de recombinaison 5c aux éléments rayonnants 2i.
