- Be arranged on the metal sheet 17 and therefore on the upper cover 13 of the antenna housing 1 1; and

The six orifices 152 are arranged facing the six orifices 172 of the metal sheet 17 which they themselves are arranged facing the six orifices 132 of the upper cover 13. They thus allow the primary antenna 15 to be fixed (or mounted) on the metal foil 17 and to be mounted on the antenna housing 1 1 ( in particular on its upper cover 13) thanks to the screws 32.

a secondary antenna 1 6; or

adapted to handle the antenna signals (of a primary antenna 15 and / or a secondary antenna 1 6) on transmission, reception and processing.

In a non-limiting embodiment, the electronic component 1 6 is connected to a PCBA2 secondary printed circuit board (called in English "Printed Circuit Board Assembly"), also hereinafter referred to PCBA2 card as seen previously. In this case, the PCBA2 card is parallel to the plane of the antenna box 1 1. In a non-limiting embodiment, the electronic component 1 6 is in turn substantially horizontal, namely substantially parallel with respect to the PCBA2 card and the antenna housing 1 1.

The PCBA2 card is adapted to be disposed inside the passenger compartment 21 of the motor vehicle 2, and in particular in the antenna housing 1 1 between the upper cover 13 and the lower cover 14.

It is disposed facing said electronic component 16, on the face of the PCBA2 card opposite to that on which said electronic component 1 6 6. The thermal paste 1 64 provides a flat contact surface between the electronic component 16 and the metal sheet 17 so as to allow good heat dissipation.

In a non-limiting embodiment illustrated in FIG. 12b, the PCBA2 card furthermore comprises:

an antenna connector 1 63 for connecting a primary antenna 15 to the antenna unit 1 1 (namely to the telematic control unit TCU in the nonlimiting example taken) and carrying antenna signals. The antenna connector 1 63 thus connects the PCBA2 card to the PCBA1 card;

- An antenna connector 1 65 adapted to make a connection with other antennas in the passenger compartment of the motor vehicle and thus transit other antenna signals.

The connection via the antenna connector 1 63 is done with an electrical connection harness of the PCBA1 card or a complementary antenna connector of the PCBA1 card.

an external connector 1 62 adapted to make a connection with a power supply of the motor vehicle and to make an interface with the motor vehicle, in particular with other components of the motor vehicle; and or

an external connector 1 66 adapted to make a connection with a high-speed network and thus enable high-speed communication.

• Metal foil 17

Said metal sheet 17 is illustrated in FIG.

In a non-limiting embodiment, the metal sheet is made of stainless steel. It is a light and inexpensive material. In a non-limiting embodiment, the metal sheet 17 comprises a thickness of between 0.2 and 0.4 mm. This makes it possible to have a thin metal sheet 17, compact and which takes up little space.

The function of the metal foil 17 is to limit any electromagnetic coupling (called EMC problem) between a primary antenna (s) 15 and an electronic component (s) 1 6 and / or between a primary antenna (s) (s) 15 and any electronic equipment in the passenger compartment 21 of the motor vehicle 2. It therefore allows good EMC protection.

Thus, the antenna signals, the operation of the electronic component (s) and / or the electronic equipment (s) are not or very little disturbed by an EMC problem.

For this purpose, the metal sheet 17 is located between these two elements 15 and 16.

The metal sheet 17 is adapted to:

- Be arranged on the antenna housing 1 1, in particular on its upper cover 13;

- Support the primary antenna 15, in particular the PCBA1 card on which said primary antenna 15 is based. It is thus disposed under said PCBA1 card and fixed to said primary antenna 15; - Be disposed above the electronic component 1 6, in particular above the PCBA2 card on which said electronic component 1 6;

- be placed under the antenna cover 12.

- It is located all or part of the roof 20. It is thus located inside the motor vehicle 2, namely in the passenger compartment 21, or partly in the passenger compartment 21 and partly in the roof 20.

It will be noted that the interior of the motor vehicle means all that is below the outer face of the roof 20, in the non-limiting embodiment of the roof. Thus, this includes what is in the roof.

In a non-limiting embodiment, the metal sheet 17 is adapted to be disposed facing the opening 200 of the roof 20 and comprises a total length L1 greater than said opening 200. It comprises flanges 177 adapted to be arranged under the roof 20.

Its width L2 '(flanges 177 excluded) is greater than or equal to the width of the opening 200.

The metal sheet 17 thus makes it possible to carry out an electrical shielding

(also called electromagnetic shielding) between the antenna signals of the primary antenna and the signals from the electronic component

16. The EMC protection function is therefore inside the passenger compartment

21 of the motor vehicle 2.

In a non-limiting embodiment, the metal sheet 17 comprises a size (length and width) greater than the PCBA1 primary printed circuit board. The electrical shielding is thus performed over the entire periphery of the primary antenna 15; in particular, because of the portions 175 which go beyond the PCBA1 as shown in Fig. 14. In this way, the EMC protection is more efficient.

In addition, the larger the surface of the metal foil 17, the better the heat dissipation of the electronic components of the PCBA2 card. In a first non-limiting embodiment illustrated in FIG. 11a, the metal foil 17 is arranged partly under the roof 20, a part being disposed in the roof 20. In particular, the metal foil 17 comprises a part 176 adapted to to be disposed in the opening 200 of the roof 20. This portion 176 integrated in the roof 20 has a length L2 and a width L2 'less than those of the opening 200 of the roof 20. The fact of integrating a portion 176 of the metal foil 17 in the roof 20 makes it possible to save space in height in the antenna housing 1 1 for electronic components 1 6.

In a second non-limiting embodiment illustrated in FIG.

1 1 b, the metal sheet 17 is disposed completely under the roof 20. In particular, the metal sheet 17 comprises a portion 176 adapted to be disposed completely under the roof 20, namely under the opening 200 of the roof 20. This part 176 under the roof 20 has a length L2 and a width L2 'greater than those of the opening 200 of the roof 20.

It will be noted that the roof 20 of the motor vehicle 2 represents the mass of the motor vehicle 2.

The metal foil 17 is in contact with the roof 20 by its parts 175 via the fastening screws 31. The fastening screws 31 thus allow the metal sheet 17 to be grounded. The metal foil 17 is therefore connected to ground.

The metal foil 17 is fixed to the PCBA1 card via the screws 32. The metal foil 17 thus makes it possible to ground the PCBA1 card via said screws 32.

The PCBA1 card is connected to the PCBA2 card via the antenna connector

163. Because the PCBA1 card is grounded, it allows the PCAB2 card to be grounded.

Thus, the grounding is possible thanks to the fixing screw 31 which connects the antenna casing assembly 1 1 and metal foil to the roof 20. This avoids having lines of magnetic fields that bypass the metal sheet 17 and which could lead to spurious signals on the antenna signals or spurious signals in the passenger compartment of the motor vehicle 2. Thus, the performance of the primary antenna 15 is improved.

In a non-limiting embodiment, the metal sheet 17 is adapted to dissipate the energy released by the electronic component 1 6. In fact, the electronic component 1 6 when it operates heats and can release a lot of heat. The metal foil 17 serves as a heat sink. In the case where there is a plurality of electronic components 16, to dissipate the energy of all the electronic components 1 6 on the PCBA2 card, in a non-limiting embodiment (not shown), the sheet metal 17 completely covers all of said electronic components 1 6. In a non-limiting embodiment, the metal sheet 17 may comprise a size equal to the size of the PCBA2 secondary printed circuit board. This makes it possible to have a greater heat dissipation surface for all the electronic components 1 6 of the PCBA2 card.

To improve the heat dissipation, in a non-limiting embodiment, said metal sheet 17 cooperates with a thermal paste 1 64 previously described disposed on the PCBA2 secondary printed circuit board on which the thermal component 1 6 rests.

Thus, the metal foil 17 in cooperation with the thermal paste 1 64 serves as a heat sink for the electronic components 16 of the PCBA2 card. Indeed, the heat released by said electronic components 16 is dissipated via the metal sheet 17 in the roof 20.

In order to dissipate the heat generated by the electronic component 16 more rapidly, in a nonlimiting embodiment illustrated in the section of FIG. 11a or FIG. 11b, the metal sheet 17 further comprises a tab of FIG. support 174 (called "gap pad") so as to create an air gap 174 'between the electronic component 16 and the roof 20. In a non-limiting example, it is substantially square or rectangular shape. This support tab 174 extends under the roof 20. In this way, the heat is removed more quickly through the roof 20. It will be noted that the leg support 174 is based on thermal paste 164 when there is. It will be noted that the section of FIG. 11a or FIG. 11b does not illustrate the attachment device 171 of the metal sheet 17.

Note that the support lug 174 is adapted to pass through the upper cover 13 of the antenna housing 1 1 so as to be opposite said at least one electronic component 1 6.

In non-limiting embodiments, the metal sheet 17 comprises:

at least one positioning device 178 for the antenna cover 12;

at least one attachment device 172 to the antenna cover 12 and to the primary antenna 15;

at least one attachment device 171 on the roof 20;

an opening 173.

These elements are described in detail below. o PlsposLtii-.de J3Qsitipjinern_ent_ 178

In a non-limiting embodiment, the positioning device 178 is an orifice adapted to cooperate with a positioning device 128 of the antenna cover 12 provided for this purpose and previously described, namely a positioning pin. This facilitates the mounting of the antenna cover 12 on the metal sheet 17. In a non-limiting embodiment, the metal sheet 17 comprises three positioning devices 178, namely here three orifices as illustrated in FIG. one is distributed at one end of the metal foil 17 and the other two at the other end of the metal foil 17. The orifices 178 thus serve as referencing for the antenna hood 12.

As described previously, it will be noted that two of these positioning devices 178 are also adapted to cooperate with two positioning devices 138 of the top cover 13 so as to position said metal sheet 17 on said upper cover 13. These two positioning devices 1 78 also serve to position the metal sheet 1 7 on the top cover 1 3. o PlsposLtLf_deiixation_1_72

In a non-limiting embodiment, the fixing device 172 is a hole adapted to cooperate with the screw 32 provided for this purpose and with the orifice 152 of the primary antenna 1 5 described above. In particular, it is adapted to be disposed facing said orifice 152. In a non-limiting embodiment, the metal sheet 1 7 comprises six attachment devices 1 72, namely here six orifices as illustrated in FIG. for a good fixation. Thus, the primary antenna 1 5 is sandwiched between the antenna cover 1 2 and the metal sheet 1 7 and is well fixed and is not likely to move. In addition, the fixing device 1 72 also makes it possible to fix the metal sheet 1 7 on the upper cover 1 3, thanks to the screw 32. Thus, the metal sheet 1 7 is sandwiched between the primary antenna 1 5, in particular the PCBA1 card, and the top cover 1 3.

Thus, the screws 32 thus make it possible to assemble the metal sheet, the primary antenna 1 5 and the top cover 1 3 together. o PlsposLtLf_deiixation_1_71

In a non-limiting embodiment, the fixing device 171 is a hole adapted to cooperate with the fixing screw 31. Said fastening screw 31 (which fixes the antenna housing 1 1 with the protective cover 1 8) is indeed adapted to pass through said orifice 1 71.

In a non-limiting embodiment, the metal sheet 17 comprises two fastening devices 71, namely two orifices as illustrated in FIG. 10, which will cooperate with two fastening screws 31 for good fixing.

Thus, at least one fastening screw 31 not only makes it possible to fasten the protective cover assembly 18, metal sheet 1 7 and antenna housing 1 1 (via its upper cover 1 1) to the roof 20, but also to ground the protective cover assembly 1 8, metal sheet 1 7 and antenna housing 1 1. It is a simple and inexpensive fixing device that allows you to fill two different functions at the same time. In the nonlimiting example illustrated, two fixing screws 31 make it possible to perform these two functions at the same time.

In a non-limiting embodiment, the metal sheet 17 further comprises a protruding portion 175 having a tab 1750 in which the fixing device 171 is made. This makes it easy to make the orifice 171. In Figure 10, two projecting portions 175 are illustrated, each comprising a tab 1750. These projecting portions 175 are adapted to cooperate with the projecting portions 135 of the top cover 13. They are located above the PCAB2 card. They improve the electrical shielding because they are located on both sides of the PCBA1 card. The fixing screws 31 allow the protruding parts 175 to be in good contact with the roof 20 and thus allow good grounding of the metal sheet 17 as seen previously.

The fixing on the roof 20 is thus ensured. Furthermore, these protruding parts 175 are adapted to partly be opposite the opening 200 of the roof 20. On the other hand, their lug 1750 is adapted to be disposed under the roof 20, which allows the metal sheet 17 of 20. The tab 1750 is in contact with the roof 20 and allows the fixing screw 31 to ground the metal sheet 17. o Qu_ver_ture_1_73

The opening 173 is adapted to pass an antenna connector 163 of the PCBA2 card on which the electronic component 1 6 rests.

Figures 13 to 18 illustrate the mounting of the antenna housing 1 1 as a whole and the metal foil 17 on said antenna housing 1 1.

As shown in FIG. 13, the metal foil 17 is disposed on the top cover 13 by the positioning devices 138 and 178. It should be noted that the foil 17 is not in contact with the PCBA2 card. As illustrated in FIG. 14, the primary antenna 15 (in particular the PCBA1 card) is disposed on the metal foil 17. As illustrated in FIG. 15, the antenna cover 12 is positioned on the metal sheet 17 (and thus on the top cover 13) so as to cover the primary antenna 15 by means of the positioning devices 128 and 178. Then, , the upper cover assembly 13, metal foil 17, PCBA1 card and antenna cover 12 is screwed with six screws 32 through fasteners 122, 132, 152, and 172. Figure 16 illustrates said screws 32.

All the elements of the antenna housing 1 1 are thus already assembled when said antenna housing 1 1 is provided to an operator who mounts the antenna module (s) 1 on the motor vehicle 2 as described below.

• Montage

The antenna module (s) 1 having been described as a whole, its assembly is described -after.

Thus, to mount the entire antenna module (s) 1 on the body 20 of the motor vehicle 2, an operator performs the following operations. The operator is for example an operator at a car manufacturer. The operator places the protective cover 18 on the roof 20 thanks to the pins 184 and the elastic tabs 185. If an aesthetic cover 19 is used, in this case, the operator:

- Place the protective cover 18 in the aesthetic cover 19 then places the assembly on the roof 20; or place the protective cover assembly 18-aesthetic cover 19 on the roof 20 if both were pre-assembled beforehand or if they are one piece.

As shown in Figure 19, the operator installs the antenna housing 1 1 under the body 20 inside the motor vehicle 2, namely here under the roof 20 in the passenger compartment 21. The operator thus positions the antenna housing assembly 1 1, metal foil 17 under the roof 20 so that the primary antenna 15 and the antenna hood 12 pass through the roof opening 200, the hood of the roof antenna 12 thus being in the protective cover 18, and so that the top cover 13 touches the roof 20, inside the passenger compartment 21. The top cover 13, the lower cover 14, the PCBA2 board and the electronic components 1 6 are under the roof 20. The top cover 13, the lower cover 14, the PCBA2 board and the electronic components 1 6 are under the roof. 20. The metal foil 17 is wholly or partly under the roof 20 according to the first or second embodiment chosen.

As illustrated in FIG. 20, the antenna cover 12 is thus covered by the protective cover 18 which has been previously placed on the roof 20 and is positioned in the protective cover 18 by virtue of the guiding and fixing protrusions. 127. Thus, the operator does not need to hold the antenna box 1 1 with the hands since the latter is held via its antenna cover 12 under the roof 20. Then, as illustrated in FIG. the operator fixes the antenna casing assembly 1 1, metal foil 17 on the roof 20 (inside the motor vehicle 2), thanks to the primary inserts 181, the fixing orifices 201, the secondary inserts 131 and the locking devices. fixing 171, via the fixing screws 31. The roof 20 is sandwiched between the antenna housing 1 1 and the protective cover 18.

The screwing makes it possible to perform a mechanical compression action on the seal 182, which makes it possible to ensure the sealing function of the whole of the antenna module (s) 1. The seal 182 is thus sandwiched between the base 180 of the protective cover 18 and the surface external roof 20. A portion of the roof 20 is sandwiched between the protective cover 18 and the antenna housing 1 1.

The entire antenna module (s) 1 is thus fixed on the roof 20.

FIG. 22 illustrates the aesthetic cover 2 on the roof 20 which covers the whole of the antenna module (s) 1.

The section of FIG. 23 illustrates the antenna housing assembly 1 1, metal foil 17, protective hood 18, aesthetic cover 19, and primary antenna 15 positioned and fixed on the roof 20.

Note that the operator can very easily dismount the metal sheet 17 and the antenna housing 1 1 of the roof 20 by unscrewing the fixing screws 31.

Of course, the description of the invention is not limited to the embodiments described above.

Thus, in other non-limiting embodiments, instead of the roof of a motor vehicle 2, the body 20 of the motor vehicle 2 on which the antenna module (s) 1 is mounted may be the bodywork of a tailgate of a motor vehicle 2 or a trunk of a motor vehicle 2.

Thus, in another non-limiting embodiment, the PCBA1 card comprises a size greater than the opening 200 of the roof 20.

Thus, in another non-limiting embodiment, the primary antenna 15 may not be arranged vertically. It can be laid horizontally. In this case, it is part of the PCBA1 card in a non-limiting example.

Thus, in a non-limiting embodiment, the antenna module (s) may not have an antenna cover 12.

Thus, in a non-limiting embodiment, the metal foil 17 may be partially disposed in the antenna casing 1 1, these parts 175 being situated outside the antenna casing 1 1.

Thus, the invention described has the following advantages in particular: it makes it possible to propose a simple mounting of the antenna module (s) 1 as a whole on the bodywork 20 (above outside the the cockpit and below the interior of the cockpit) motor vehicle 2;

it allows, thanks to the metal foil 17, an EMC protection between the primary antenna 15 and an electronic component 1 6 of the antenna casing 1 1, and good heat dissipation;

it allows to have a module antenna (s) 1 compact and easy to mount;

it proposes to use only two fastening screws 31 to mount the protective cover assembly 18, metal foil 17 and antenna housing 1 1 on the roof 20.

it proposes to use a simple means such as a fixing screw 31 for a grounding of the whole of the antenna module (s) 1;

it makes it possible to use the same means, the fixing screw 31, to fix the antenna module (s) 1 on the bodywork 20 and for a grounding of said antenna module (s) 1;

it makes it possible to have a metal sheet 17 which can be easily dismantled; it makes it possible to have a lighter, less bulky, and thinner electrical shield than if it was the top cover 13 that performed this function;

it makes it possible to use a plastic antenna casing 1 1 while having an electric shielding, which makes it possible to have a lighter antenna casing; it allows to have an electric shield with a single element, namely the metal sheet 17.
