Definitions
- the present invention relates to the integration of a transmitting and / or receiving ribbon antenna on a mechanical support, in particular in a motor vehicle.
- the invention relates to the positioning of a large ribbon antenna with respect to a mechanical support present in a motor vehicle.
- the need for communication - transmission and / or reception of information - between the vehicle and elements external to the vehicle such as remote controls or interactive badges for hands-free access systems require the use of large antennas dimensions that are integrated in particular in the roof, the floor or the internal console of the vehicle.
- the ribbon antennas made up of n multi-stranded conductors connected one by one by a connector are known to date and produced by methods known to those skilled in the art.
- Document JP 57186802 presents in particular the use of such an arrangement as an antenna.
- Document EP 0780 027 presents the integration of a ribbon antenna on a small rectangular flat surface.
- the arrangement described requires a 45 ° folding of the sheet.
- the production of 45 ° bends is complicated and time-consuming, especially when integrating a large tablecloth antenna on large flat surfaces such as the roof or the floor of a motor vehicle.
- the object of the invention is to achieve the integration of a ribbon antenna on a preferably surface mechanical support by limiting the interference due to the facing of the antenna with metal walls such as the pavilion or the floor d 'a motor vehicle.
- the invention achieves its object by the use of a ribbon antenna transmitting and / or receiving electromagnetic field, in particular for a motor vehicle, formed of stranded conductors connected one by one for the formation of turns.
- the ribbon antenna is characterized in that 'it is positioned on a mechanical support mainly perpendicular to the surface defined by the turns.
- the ribbon antenna is positioned mainly perpendicular to the mechanical support, the surface of the mechanical support corresponding to the surface of the turns, the mechanical support consists of a piece of non-metallic material, - the mechanical support consists of at at least two juxtaposed parts, the ribbon antenna is held on the mechanical support by mechanical holding means, the holding means are positioned on the mechanical support, the holding means are positioned on one or more adjacent walls and mainly perpendicular to the support antenna mechanics, the holding means are made in the form of a groove made in or on the mechanical support, the holding means are made in the form of a clip positioned on the mechanical support or on a wall adjacent to the mechanical support, the means holding are made in the form of staples, the antenna is glued to the mechanical support or on a wall adjacent to the mechanical support, - the antenna is directly integrated into the support by molding,
- the ribbon antenna is integrated in a vehicle fitted with a hands-free access and / or starting system.
- Figure la is a sectional view "of a motor vehicle having possible integration surfaces of a ribbon antenna according to the invention
- Figure lb is a top view of a motor vehicle showing the possible integration surfaces of Figure la.
- Figures 2a and 2b are sectional views of the roof of a motor vehicle showing the integration and maintenance of a ribbon antenna according to the invention.
- Figures 3a and 3b are sectional views of another means for holding the ribbon antenna integrated in a motor vehicle.
- Figures la and lb show in two different sections a motor vehicle 1. It shows several possibilities of integration of a ribbon antenna 5 in different places of the vehicle, in particular at the level of the roof 2, of the console 3 and of the floor 4 It is interesting to cover the console 3 and the floor 4 with a single antenna to avoid field destruction and save a driver.
- the shape of the antenna thus formed is rectangular but can be circular, square or of any other shape and its mode of integration makes it possible to avoid folding.
- the integration of the ribbon antenna according to the invention is carried out by positioning the ribbon antenna mainly perpendicular to the surface defined by the turns of said antenna.
- This surface defined by the turns of the antenna corresponds, in the case of the vehicle roof, of the console, of the floor or of the console-floor assembly, to the surface mechanical support on which the ribbon antenna is positioned.
- the ribbon antenna is in a position generally perpendicular to the surface mechanical support.
- the ribbon antenna is placed on two juxtaposed mechanical supports which are not in the same plane but which correspond to a surface-equivalent to that defined by the turns of the antenna.
- the ribbon antenna is held on this support by means of holding means.
- the means for holding the antenna on the mechanical support presented in FIGS. 2a and 2b form an integral part of the support.
- the holding means are produced in the form of a groove 6a formed on the surface of the upper face of the pavilion.
- This groove is made around the entire periphery of the pavilion for the integration of the ribbon antenna at the level of the roof 10 of a motor vehicle.
- the groove 6a makes it possible to receive the ribbon antenna and to maintain it in a position mainly perpendicular relative to the surface defined by the turns, that is to say in this arrangement, relative to the pavilion which forms the mechanical support of the 'cable antenna.
- the groove 6a is directly produced on the surface on the roof during the manufacture of the latter. It is also possible to provide an independent groove which is then bonded to the roof.
- FIG. 2a shows the use of a groove 6a on the roof of a motor vehicle, but this type of groove can be positioned in other places of the vehicle such as, for example, the floor, the door jambs, etc. as required.
- Figure 2b shows a second embodiment of the groove.
- the groove 6b is made directly in the mass of the pavilion and consists of a local obviously of rectangular section traversing the entire periphery of the pavilion. Obviously this groove 6b can be made in other places of the vehicle for receiving a ribbon antenna.
- FIG. 3a shows another means of maintaining the ribbon antenna at the level of an internal console of a motor vehicle.
- This holding means is a clip 7 positioned on a wall of the console 3, this wall 8 is adjacent to the mechanical support 9 on which the ribbon antenna is placed.
- This clip 7, preferably made of plastic, is fixed by means of a hinge to the adjacent wall 8 of the console 3. Before positioning the ribbon antenna on the mechanical support 9, the clip is in the open position and is awaiting the insertion of the ribbon antenna 5. When the ribbon antenna is positioned, the clip 7 is folded over it to hold it in place and press it down between the wall 8 and the mechanical support 9.
- FIG. 3b also presents holding means produced in the form of a clip 7, this clip being directly positioned on the mechanical support 9. It is therefore not necessary to have an adjacent wall to use a clip as a means of positioning of the ribbon antenna on the mechanical support.
- the means for holding the ribbon antenna on its mechanical support, so that it is positioned mainly perpendicular to the surface defined by the turns, can be produced in different ways.
- the ribbon antenna can be directly stapled or glued to its mechanical support or to a wall adjacent to the mechanical support.
- a more advantageous solution is to integrate the ribbon antenna directly during the manufacture of its mechanical support, in particular when it is intended to be integrated in a roof or in an element such as the vehicle floor.
- the antenna can thus be directly molded during the manufacture of its support element.
