As is well known to those skilled in the art, a GNSS module for a vehicle includes a GNSS patch antenna and a printed electronic circuit assembly, which is used in the vehicle for locating the vehicle. GNSS patch antennas are antennas that are typically larger than 18mm x 18mm in size for automotive use. Selective wave soldering is generally recommended for assembling GNSS patch antennas to printed electronic circuit assemblies, but is not recommended for use in automotive parts due to cost and robustness issues. The automotive industry prefers reflow soldering.
To solder the patch antenna with a reflow process, a GNSS patch antenna bonding process is required in advance due to the weight of the GNSS patch antenna, and a customized GNSS patch antenna pin length to allow for solder paste printing capability. This solution is expensive and time consuming because it requires additional machines (gluing and polymerization) that are not typically available on standard SMD (Surface Mount Device) assembly lines, except for custom GNSS patch antennas.

a rubber connector 12, and
a housing 13.
In a non-limiting embodiment, the GNSS module 1 is a GPS, GLONASS, GALILEO or BEIDOU module. In a non-limiting embodiment of the cited art, the GNSS module is configured to receive signals from GNSS satellites and to process said signals in order to locate the vehicle.
As shown in fig. 1b, 1c, 1d, 2b, 2c, 3b and 3c, the GNSS patch antenna 10 comprises an electrical access pad 100, the electrical access pad 100 being configured to electrically contact the through electrical contact 120 of the rubber connector 12. In a non-limiting embodiment, the electrical access pad 100 is located on a bottom side 10b of the GNSS patch antenna 10 opposite the top side 10 a.
In a non-limiting embodiment, the GNSS patch antenna 10 has dimensions greater than 18mm by 18 mm. In a non-limiting embodiment, the GNSS patch antenna 10 is made in part of ceramic.
As shown in fig. 1d, in a non-limiting variation of the embodiment, the GNSS patch antenna 10 further comprises a ground pad 103 configured to electrically contact another through electrical contact 123 of the rubber connector 12. In a non-limiting embodiment, the ground pad 103 is located on the bottom side 10b of the GNSS patch antenna 10 opposite the top side 10 a.
As shown in fig. 1a to 3b, the rubber connector 12 comprises through electrical contacts 120, the through electrical contacts 120 being configured to electrically contact the electrical antenna pads 100 of the GNSS patch antenna 10 on a top side 12a thereof, and to electrically contact the electrical pads 110 of the printed electronic circuit assembly 11 on a bottom side 12b opposite to the top side 12 a.
In a non-limiting embodiment, the rubber connector 12 is in an elastomer. This allows the rubber connector 12 to be compressed.

The electrical pads 110 are configured to electrically contact through electrical contacts 120 of the rubber connector 12. In a non-limiting embodiment, the thickness of the electrical pad 110 is 0.5 to 2 millimeters (mm).
In a non-limiting embodiment, the printed electronic circuit assembly 11 further comprises electronic components 112 for processing signals of GNSS satellites received by the GNSS patch antenna 10.
