- the two plates 4 and 17 (or the two plates 5 and 18) can be rigidly attached to each other. However he it is better to provide joints electrically conductors 6 and 7 respectively between the two plates adjacent 4 and 17 and between the two adjacent plates 5 and 18.

Description
La présente invention concerne un récepteur portable comportant un boítier dans lequel est placé un circuit électronique, et une antenne pour la réception d'ondes électromagnétiques, ladite antenne comportant:
- deux plaques dites principales électriquement conductrices, chacune attachée le long d'une ligne à l'extérieur et de part et d'autre du boítier, de façon pratiquement symétrique,
- et deux plaques dites parallèles, qui sont pratiquement triangulaires avec leurs pointes tournées l'une vers l'autre et qui sont contenues dans un même plan symétriquement l'une par rapport à l'autre, et qui sont respectivement reliées, par un de leurs côtés, au côté tourné vers le boítier de chacune des plaques principales,
- les plaques principales et les plaques parallèles formant un angle entre elles au moins position d'utilisation.
- two so-called electrically conductive main plates, each attached along a line to the outside and on either side of the case, in a practically symmetrical manner,
- and two so-called parallel plates, which are practically triangular with their points facing one another and which are contained in the same plane symmetrically with respect to each other, and which are respectively connected, by one of their sides, on the side facing the housing of each of the main plates,
- the main plates and the parallel plates forming an angle between them at least position of use.
Un tel récepteur est par exemple un récepteur de radio ou un récepteur de télévision à écran plat, ou un récepteur de télétexte à écran plat, par exemple muni d'un écran à cristaux liquides.Such a receiver is for example a radio receiver or a flat screen TV receiver, or a receiver flat screen teletext, for example with a flat screen liquid crystals.
La demande de brevet internationale WO 90/15452 décrit une antenne de radar, destinée à recevoir une fréquence déterminée, et comportant deux parties qui sont chacune constituées d'une zone triangulaire et d'une zone rectangulaire, et qui sont pliées à angle droit le long de l'axe qui délimite ces deux zones afin de limiter l'encombrement de l'antenne. L'antenne décrite dans ce document est une antenne demi-onde, c'est-à-dire que sa longueur totale est de l'ordre de grandeur d'une demi longueur d'onde. Par ailleurs les zones rectangulaires de l'antenne sont moins longues que ses zones triangulaires.International patent application WO 90/15452 describes a radar antenna, intended for receive a determined frequency, and comprising two parts which are each made up of a triangular area and a rectangular area, and which are bent at right angles along the axis which delimits these two zones in order to limit the size of the antenna. The antenna described in this document is a half-wave antenna, that is to say that its total length is the order of magnitude of half a wavelength. In addition, the rectangular areas of the antenna are shorter than its triangular areas.
Un objet de l'invention est d'obtenir un diagramme de réception parfaitement omnidirectionnel sur l'ensemble de la bande de fréquence dite UHF, avec un gain élevé. An object of the invention is to obtain a reception diagram perfectly omnidirectional over the entire UHF frequency band, with a high gain.
Un tel objectif est atteint avec un récepteur tel que décrit dans le paragraphe introductif et caractérisé en ce que, pour une utilisation dans la gamme de fréquences dite UHF,
- les deux plaques dites principales sont plus longues que les deux plaques dites parallèles,
- et la distance, mesurée en longeant les plaques de l'antenne (2, 3, 4, 5), entre les extrémités les plus éloignées l'une de l'autre des deux plaques principales (21,22), est de l'ordre d'une longueur d'onde d'une fréquence à recevoir.
- the two so-called main plates are longer than the two so-called parallel plates,
- and the distance, measured along the antenna plates (2, 3, 4, 5), between the ends furthest from each other of the two main plates (21,22), is order of a wavelength of a frequency to receive.
L'utilisation d'une longueur d'antenne de l'ordre de grandeur d'une longueur d'onde d'une fréquence à recevoir permet d'élargir la bande de fréquences susceptible d'être reçue. L'arrangement choisi permet d'obtenir un diagramme de rayonnement pratiquement circulaire sur l'ensemble de la bande dite UHF. The use of an antenna length of the order of magnitude of a wavelength of a frequency to receive widens the frequency band likely to be received. The arrangement chosen provides a practically circular radiation pattern on the whole of the so-called UHF band.
Avantageusement, les plaques parallèles pratiquement triangulaires ont un dessin dissymétrique par rapport à un axe horizontal.Advantageously, the parallel plates practically triangular have an asymmetrical design compared to a horizontal axis.
Ceci permet d'obtenir un meilleur fonctionnement lorsque le boítier est incliné.This allows better operation when the case is tilted.
Dans une forme de réalisation particulière, une plaque parallèle est reliée à une plaque principale via une plaque de raccordement faisant un angle à la fois avec la plaque principale et avec la plaque de raccordement.In a particular embodiment, a plate parallel is connected to a main plate via a plate of connection making an angle at a time with the plate main and with the connection plate.
Ceci permet de "boucher" encore mieux les creux du diagramme directionnel.This allows the hollows of the directional diagram.
Les plaques principales et le boítier ont avantageusement, dans une direction parallèle à la ligne d'attache d'une plaque, pratiquement la même dimension maximale.The main plates and the housing have advantageously, in a direction parallel to the line plate attachment, practically the same size Max.
Dans une forme de réalisation, les plaques sont faites de matière plastique, et sont recouvertes d'une feuille souple métallisée.In one embodiment, the plates are made of plastic, and are covered with a sheet flexible metallic.
Une telle feuille métallisée souple est capable d'assurer une continuité au niveau des articulations, en se pliant lorsqu'on fait jouer l'articulation, ou même peut constituer par elle même une charnière.Such a flexible metallized sheet is capable ensure continuity at the joints, by folding when the joint is played, or even can constitute by itself a hinge.
Un récepteur portable selon l'invention est avantageusement un récepteur d'images muni d'un écran image.A portable receiver according to the invention is advantageously an image receiver provided with an image screen.
Dans une forme de réalisation particulière, l'écran image est placé entre les pointes des plaques parallèles pratiquement triangulaires.In a particular embodiment, the screen picture is placed between the tips of the parallel plates practically triangular.
Ces aspects de l'invention ainsi que d'autres aspects
plus détaillés apparaítront plus clairement grâce à la
description suivante d'un mode de réalisation constituant un
exemple non limitatif.
Les figures 1 et 2 représentent schématiquement un récepteur
selon l'invention, vu respectivement de face et de dessus.
La figure 3 représente, vue de dessus, une variante.These aspects of the invention as well as other more detailed aspects will become more clearly apparent from the following description of an embodiment constituting a nonlimiting example.
Figures 1 and 2 schematically represent a receiver according to the invention, seen respectively from the front and from above. Figure 3 shows a top view of a variant.
Le récepteur d'images portable 1 illustré sur les
figures comporte un boítier 8 dans lequel est placé un
circuit électronique 11-16. Ce boítier 8, qui pourrait aussi
bien avoir n'importe quelle forme, est ici pratiquement plat
et rectangulaire. Il est pratiquement symétrique par rapport
à un plan de symétrie 19 perpendiculaire à ses grandes
faces, et perpendiculaire au plan de la feuille de dessin. The portable image receiver 1 illustrated on the
figures includes a
Le boítier 8 est muni d'un écran image 20 (figure 2),
par exemple à cristaux liquides, qui occupe une partie de sa
grande face plane qui est tournée vers le bas sur la figure.The
Le récepteur est destiné à la réception d'ondes dans la gamme de fréquences dite UHF, et notamment à la réception d'émissions de télétexte.The receiver is intended for the reception of waves in the frequency range called UHF, and in particular at reception teletext broadcasts.
Il est muni d'une antenne qui comprend deux plaques 4
et 5, électriquement conductrices. Ces deux plaques sont
disposées de part et d'autre du boítier 8 et attachées de
façon pratiquement symétrique par rapport à ce boítier 8, et
par rapport au plan de symétrie 19. Les plaques 4 et 5 font
ici entre elles un angle dont le sommet S est derrière
l'écran, pour un observateur situé en face de l'écran, cette
disposition étant visible sur la figure 2, où les plans des
plaques 4, 5 sont perpendiculaires à la feuille de dessin.It is provided with an antenna which includes two
La distance entre les extrémités 21 et 22, les plus
éloignées l'une de l'autre, des plaques 4 et 5 est de
l'ordre d'une longueur d'onde λ de la fréquence centrale de
la gamme de fréquences à recevoir, mesurée en suivant la
surface des plaques entre les points 21 et 22.The distance between the
L'antenne comporte en outre deux plaques 2, 3 dites
parallèles qui sont placées parallèlement au boítier plat 8
et reliées électriquement et mécaniquement à la première
plaque 4 et à la seconde plaque 5, respectivement.The antenna further comprises two
On peut aussi imaginer une disposition des mêmes
éléments dans laquelle le boítier 8 serait retourné recto-verso
par rapport à la position qu'il occupe sur la figure
2, c'est-à-dire que l'écran serait tourné vers le haut de la
figure, le boítier étant placé au dessus des plaques 2 et 3,
le sommet S étant alors en avant de l'écran.We can also imagine a layout of the same
elements in which the
L'écran à cristaux liquides 20 est situé à proximité
des plaques 2, 3, mais il ne joue pas le rôle d'un plan de
masse, car il n'est pas bon conducteur pour les fréquences
en jeu. Tout au plus joue-t-il approximativement un rôle
d'élément directeur, au sens de ce mot dans les antennes
yagi. De même, pour ne pas perturber le fonctionnement de
l'antenne, le circuit électronique dans le boítier 8 est
divisé en plusieurs sous-ensembles 11, 12, 13, 14, 15, 16,
dont les plans de masse sont électriquement reliés les uns
aux autres via des inductances 161, 112, 114, 134, 145.The
Les plaques parallèles 2 et 3 ont un dessin à peu près
triangulaire (figure 1). Les triangles sont dissymétriques,
autrement dit ils ne sont pas isocèles. Par exemple la
pointe à droite de la plaque 2 et la pointe à gauche de la
plaque 3 sur la figure 1 sont plus hautes que le milieu des
plaques et du boítier. Cette dissymétrie n'est pas toujours
nécessaire. Au lieu de plaques triangulaires, on pourrait
utiliser des plaques semi-circulaires ou semi-elliptiques
sans que cela change grand chose, de telles formes étant
assimilables à des formes triangulaires "émoussées".The
Une liaison électrique vers le circuit électronique
peut être connectée à l'antenne en un point 9 près de la
pointe de la plaque parallèle 2 qui est tournée vers l'autre
plaque parallèle 3, et en un point 10 près de la pointe de
la plaque parallèle 3 qui est tournée vers l'autre plaque
parallèle 2. En pratique, un symétriseur adaptateur
d'impédance d'un type connu (non représenté) est connecté
entre les points 9 et 10 de l'antenne, et la liaison
électrique vers le circuit électronique peut de ce fait être
connectée en un seul des points 9 ou 10. Le syntoniseur
relié à l'un de ces points est par exemple l'élément 11.An electrical connection to the electronic circuit
can be connected to the antenna at a point 9 near the
tip of the
L'antenne peut comporter en outre (figure 2) une plaque
de raccordement 17 disposée entre les plaques 4 et 2 et qui
les relie électriquement et mécaniquement. Une autre plaque
de raccordement électriquement conductrice 18 est disposée
de la même façon entre les plaques 3 et 5, qu'elle relie
mécaniquement et électriquement. Ces plaques font avec les
plaques 2, 3 un angle de 90° et avec les plaques 4, 5 un
angle de 45° environ, dans la position qui est représentée,
mais qui est réglable comme cela sera expliqué plus bas.The antenna may further include (Figure 2) a
Les plaques principales 4 et 5, ainsi que les plaques
de raccordement 17, 18 sont par exemple rectangulaires et
elles ont une hauteur à peu près égale à celle du boítier.
On pourrait aussi imaginer par exemple des plaques principales trapézoïdales, ou aussi demi-circulaires (raccordées aux plaques de raccordement le long d'un diamètre vertical), avec toutefois des caractéristiques un peu dégradées dans ce dernier cas.We could also imagine for example plates main trapezoidal, or also semicircular (connected to the connection plates along a vertical diameter), with characteristics one little degraded in the latter case.
Les deux plaques 4 et 17 (ou les deux plaques 5 et 18)
peuvent être fixées rigidement l'une à l'autre. Toutefois il
est préférable de prévoir des articulations électriquement
conductrices 6 et 7 respectivement entre les deux plaques
adjacentes 4 et 17 et entre les deux plaques adjacentes 5 et
18. Cela permet d'ajuster l'angle entre les plaques 4 et 17,
ou 5 et 18, et aussi de replier les plaques pour le
transport du récepteur.The two
Dans une autre disposition qui est illustrée par la
figure 3, les parties d'antenne 2 et 3 triangulaires sont
placées devant le boítier, de part et d'autre de l'écran 20.
En outre les parties de raccordement 17 et 18 sont absentes.
Là aussi, l'écran 8 pourrait être tourné vers le haut. Des
articulations électriquement conductrices 6 et 7 sont
prévues entre respectivement les deux plaques adjacentes 4
et 2 et les deux plaques adjacentes 5 et 3.In another arrangement which is illustrated by the
Figure 3, the
Les plaques 17, 2 (ou 18, 3) peuvent être faites d'une
seule tôle, par exemple en aluminium, pliée. Dans le cas où
l'on ne prévoit pas d'articulation 6 (ou 7), c'est même
l'ensemble des plaques 4, 17, 2 (ou 5, 18, 3) qui peut être
fait d'une seule tôle pliée. Les plaques métalliques peuvent
être gainées de plastique ou peintes pour améliorer leur
aspect.
Dans une variante, les plaques et les articulations peuvent être réalisées en matière plastique, les plaques étant recouvertes d'une feuille souple métallisée, par exemple collée sur les plaques en matière plastique.In a variant, the plates and the joints can be made of plastic, the plates being covered with a metallized flexible sheet, by example stuck on plastic plates.
