Description

Une antenne à plaquette, ou encore antenne patch, est constituée d'une couche rayonnante (patch) et d'une couche de masse séparée par une couche de diélectrique, la couche rayonnante étant excitée par un fil chaud d'un connecteur d'excitation relié à la couche de masse. Incidemment, si la couche de diélectrique n'est pas de l'air et donc de permittivité différente de 1, l'antenne est dite microbande (microstrip).A patch antenna, or even patch antenna, is formed a radiant layer (patch) and a mass layer separated by a dielectric layer, the radiating layer being excited by a hot wire an excitation connector connected to the ground layer. Incidentally, if the dielectric layer is not air and therefore has a permittivity other than 1, the antenna is called microstrip.

Pour élargir la bande de fréquences, on peut disposer au-delà de la couche rayonnante, du côté opposé à la couche de masse, une ou plusieurs couches parasites, ou toits capacitifs.To widen the frequency band, one can have beyond the radiant layer, on the side opposite the ground layer, one or more parasitic layers, or capacitive roofs.

De telles antennes sont intéressantes notamment à des fréquences de l'ordre de 2000 MHz de la bande de radiotéléphonie cellulaire UMTS. Toutefois, on utilise ces antennes dans un domaine de fréquences s'étendant grossièrement de 100 MHz à 40 Ghz.Such antennas are advantageous in particular at frequencies of around 2000 MHz of the UMTS cellular radiotelephony band. However, these antennas are used in a frequency domain extending roughly from 100 MHz to 40 GHz.

Pour augmenter le gain, on peut mettre ces antennes en réseau. Pour cela, il faut disposer d'une couche d'alimentation des différents éléments d'antenne, du côté de la couche de masse opposé à la couche rayonnante. Mais comme le connecteur d'excitation doit être relié à une couche de masse, on a proposé d'utiliser dans un réseau d'éléments d'antenne patch une alimentation triplaque, c'est-à-dire une couche d'alimentation s'étendant entre deux couches de masse.To increase the gain, these antennas can be networked. For this requires a supply layer of the different elements antenna, on the side of the ground layer opposite the radiating layer. But as the excitation connector must be connected to a ground layer, we have proposed to use a power supply in a patch antenna array triplate, i.e. a feed layer extending between two mass layers.

Toutefois, cette solution ne permet pas d'accéder à la couche d'alimentation pour déphaser les divers éléments du réseau et ainsi orienter comme on le désire l'axe du diagramme de rayonnement du réseau.However, this solution does not allow access to the layer supply to phase the various elements of the network and thus orient as desired the axis of the network radiation pattern.

L'idée d'enlever la deuxième couche de masse soulève la difficulté de relier le fil chaud du connecteur à la couche d'alimentation en faisant passer la gaine de masse du connecteur, dans laquelle s'étend le fil çhaud, à travers une ouverture ménagée dans la couche d'alimentation.The idea of removing the second layer of mass raises the difficulty to connect the hot wire of the connector to the supply layer by making pass the ground sheath of the connector, in which the hot wire extends, to through an opening in the supply layer.

L'invention de la présente demande vise à résoudre ce dilemme.The invention of the present application aims to resolve this dilemma.

A cet effet, l'invention concerne un réseau d'éléments d'antenne patch, comprenant une couche rayonnante de patches, une couche d'un circuit d'alimentation des patches de la couche rayonnante, une couche de masse entre la couche rayonnante et la couche d'alimentation et un connecteur à fil chaud d'excitation disposé au droit d'une zone de la couche d'alimentation hors du circuit d'alimentation et le fil chaud étant relié à la couche d'alimentation par l'intermédiaire de la couche rayonnante.To this end, the invention relates to an array of antenna elements patch, comprising a radiating layer of patches, a layer of a circuit feeding the patches of the radiant layer, a layer of mass between the radiant layer and the supply layer and a wire connector excitation heat arranged in line with an area of the supply layer out of the supply circuit and the hot wire being connected to the layer supply via the radiant layer.

On a ainsi transformé la couche rayonnante du réseau en couche rayonnante et d'alimentation. En d'autres termes, le réseau comporte deux couches d'alimentation.We have thus transformed the radiating layer of the network into a layer radiant and nourishing. In other words, the network has two feeding layers.

L'invention est remarquable par le fait qu'en voulant enlever une couche de masse, on a créé une deuxième couche d'alimentation confondue avec la couche rayonnante.The invention is remarkable in that by wanting to remove a mass layer, we created a second mixed supply layer with the radiant layer.

Avantageusement, les patches des éléments d'antenne de la couche rayonnante du réseau sont excités par la couche d'alimentation par l'intermédiaire de vias traversant la couche de masse.Advantageously, the patches of the antenna elements of the layer radiating from the network are excited by the power layer by via vias passing through the mass layer.

Dans la forme de réalisation préférée du réseau de l'invention, le fil chaud du connecteur d'excitation est relié à la couche rayonnante et d'alimentation et à la couche d'alimentation par l'intermédiaire de deux vias traversant la couche de masse.In the preferred embodiment of the network of the invention, the wire hot from the excitation connector is connected to the radiant layer and feed and to the feed layer via two vias crossing the mass layer.

De préférence, le réseau comporte au moins une deuxième couche rayonnante de patches secondaires séparés de la première couche rayonnante de patches primaires par une entretoise de permittivité sensiblement égale-à 1, pour, par son épaisseur, pouvoir contrôler la bande passante du réseau.Preferably, the network comprises at least a second layer radiating from secondary patches separated from the first radiating layer primary patches by a spacer of permittivity substantially equal to 1, for its thickness, being able to control the network bandwidth.

Le circuit d'alimentation peut comporter une seule entrée d'alimentation par élément d'antenne, pour obtenir un réseau à polarisation linéaire ou au moins deux entrées d'alimentation par élément d'antenne, pour obtenir un réseau à polarisation circulaire.The supply circuit can have a single input power supply by antenna element, to obtain a polarization network linear or at least two power inputs per antenna element, for obtain a circularly polarized network.

Avantageusement, le circuit d'alimentation est imprimé sur la couche d'alimentation avec une plage d'entrée d'alimentation métallisée de liaison au fil chaud d'excitation du connecteur et une plage de masse métallisée globalement annulaire de liaison à une gaine de masse du connecteur d'excitation et à un via la reliant à la couche de masse.Advantageously, the supply circuit is printed on the feed layer with a metallized feed input range of connection to the connector's excitation hot wire and a mass range generally annular metallized connection to a ground sheath of the excitation connector and to a via connecting it to the ground layer.

De préférence, les patches rayonnants et une plage métallisée d'excitation et de liaison de la couche rayonnante et de la couche d'alimentation sont imprimés sur la couche rayonnante.Preferably, the radiating patches and a metallized range excitation and bonding of the radiating layer and the layer are printed on the radiant layer.

L'invention sera mieux comprise à l'aide de la description suivante de la forme de réalisation préférée du réseau d'éléments d'antenne de l'invention, en référence au dessin annexé, sur lequel :

  • la figure 1 représente une vue de dessous de la couche d'alimentation, avec le circuit d'alimentation ;
  • la figure 2 représente une vue du dessus de la couche rayonnante et d'alimentation ; et
  • la figure 3 représente une vue du réseau en coupe à travers les plages d'entrée d'alimentation et de masse de la couche d'alimentation.
The invention will be better understood using the following description of the preferred embodiment of the array of antenna elements of the invention, with reference to the attached drawing, in which:
  • Figure 1 shows a bottom view of the supply layer, with the supply circuit;
  • Figure 2 shows a top view of the radiating and supply layer; and
  • FIG. 3 represents a view of the network in section through the supply and mass input areas of the supply layer.

Le réseau d'éléments d'antenne plaquette (patch) qui va maintenant être décrit comporte une couche de masse 1, une couche d'alimentation 2 et une couche rayonnante et d'alimentation 3. La couche de masse 1 est constituée d'une substrat 4 sur lequel a été déposé un film métallisé 5 tourné vers la couche d'alimentation 2.The array of patch antenna elements that will now to be described comprises a ground layer 1, a supply layer 2 and a radiant and supply layer 3. The mass layer 1 is consisting of a substrate 4 on which a metallized film 5 has been turned to the feed layer 2.

La couche rayonnante et d'alimentation 3 est constituée d'un substrat 6 sur lequel a été déposés ici quatre patches rayonnants circulaires 7 et une plage métallisée d'excitation 8, ici rectangulaire, de plus petite surface que les patches.The radiant and supply layer 3 consists of a substrate 6 on which four circular radiating patches have been deposited here 7 and a metallized excitation area 8, here rectangular, of smaller area than the patches.

La couche d'alimentation 2 est constituée d'un substrat sur lequel a été imprimé un circuit d'alimentation 9, avec une plage métallisée d'entrée d'alimentation 10 et une plage métallisée de masse 11.The supply layer 2 consists of a substrate on which has been printed a supply circuit 9, with a metallized input range supply 10 and a metallized mass area 11.

Les couches de masse 1 et d'alimentation 2 sont séparées par un diélectrique 12 caractérisé par sa permittivité, ici supérieure à 2, en l'espèce 2, 3, par exemple en verre-téflon, pour assurer un bon rayonnement à une longueur d'onde supérieure à 2 Ghz. The layers of mass 1 and of supply 2 are separated by a dielectric 12 characterized by its permittivity, here greater than 2, in this case 2, 3, for example in Teflon glass, to ensure good radiation to a wavelength greater than 2 Ghz.

Les patches 7 de la couche rayonnante sont excités par un connecteur 13 duquel sortent une gaine de masse 14 et un fil chaud d'excitation 15.The patches 7 of the radiating layer are excited by a connector 13 from which a ground sheath 14 and a hot wire emerge excitement 15.

Le circuit d'alimentation 9 comporte donc la plage d'entrée 10 et, ici, comme il y a quatre patches rayonnants et que le réseau doit être à polarisation circulaire, huit languettes d'extrémité 16, pour l'excitation des patches, c'est-à-dire deux par patch, avec, entre ces languettes et la plage d'entrée, de façon classique pour un réseau d'antennes patch, les déphaseurs et commutateurs imprimés le long du circuit. La plage d'entrée 10 a une forme de petite pastille oblongue raccordée au circuit principal 9 par deux coudes.The supply circuit 9 therefore includes the input range 10 and, here, as there are four radiating patches and the network must be at circular polarization, eight end tabs 16, for excitation of patches, that is to say two per patch, with, between these tabs and the beach input, conventionally for an array of patch antennas, phase shifters and switches printed along the circuit. Input area 10 has a shape small oblong patch connected to the main circuit 9 by two elbows.

Entre la plage d'entrée 10 et la languette d'extrémité 16 adjacente se trouve la plage de masse 11. Elle a une forme globalement annulaire mais à contour externe sensiblement carré.Between the input area 10 and the adjacent end tab 16 is finds the mass range 11. It has a generally annular shape but at substantially square external contour.

Le connecteur 13 est donc disposé au droit de cette zone 11 de la couche d'alimentation 2 qui se trouve hors du circuit d'alimentation 9.The connector 13 is therefore placed in line with this zone 11 of the supply layer 2 which is outside the supply circuit 9.

La gaine de masse 14 du connecteur 13 est raccordée à la plage 11 et au film de masse 5 de la couche 1 par un via 17.The ground sheath 14 of the connector 13 is connected to the track 11 and to the mass film 5 of layer 1 via a via 17.

La plage d'entrée 10 de la couche d'alimentation 2 est reliée à la plage d'excitation 8 de la couche rayonnante et d'alimentation 3 par un via 18 traversant la couche de masse 1. Le fil chaud d'excitation 15 du connecteur 13, qui s'étend dans la gaine de masse 14, est relié à la plage d'excitation 8 par un via 19 traversant la couche de masse 1 et s'étendant entre la plage de masse 11 et la plage d'excitation 8. La plage d'entrée 10 est donc reliée au fil chaud d'excitation 15.The input area 10 of the supply layer 2 is connected to the excitation range 8 of the radiating layer and supply 3 by one via 18 passing through the ground layer 1. The hot excitation wire 15 of the connector 13, which extends into the ground sheath 14, is connected to the excitation range 8 by a via 19 crossing the mass layer 1 and extending between the mass range 11 and the excitation range 8. The input range 10 is therefore connected to the hot wire excitement 15.

Ainsi, la plage d'entrée d'alimentation 10 et, en partie, la plage de masse 11 sont imprimées sur la couche d'alimentation 2 en regard de la plage d'excitation 8 de la couche rayonnante 3. De même, les extrémités des languettes d'excitation 16 se trouvent, deux par deux, en regard des patches respectifs 7 de la couche rayonnante 3, auxquels elles sont reliées par des vias 20, traversant la couche de masse 1. Thus, the power input range 10 and, in part, the range of mass 11 are printed on the supply layer 2 opposite the range excitation 8 of the radiating layer 3. Similarly, the ends of the excitation tabs 16 are located, two by two, opposite the patches respective 7 of the radiating layer 3, to which they are connected by vias 20, crossing the layer of mass 1.

Il peut être intéressant de prévoir une couche de patches secondaires du côté de la couche rayonnante et d'alimentation 3 opposé à la couche de masse 1, séparée de la couche 3 des patches primaires 7 par une entretoise diélectrique de permittivité sensiblement égale à 1, par exemple de la mousse, d'une part, pour réduire au mieux les pertes et, d'autre part, pouvoir contrôler la bande passante du réseau.It may be interesting to provide a layer of secondary patches on the side of the radiant and supply layer 3 opposite the layer of mass 1, separated from layer 3 of primary patches 7 by a spacer dielectric with permittivity substantially equal to 1, for example foam, on the one hand, to minimize losses and, on the other hand, to be able to control network bandwidth.
