Screwable vehicle antenna
View Patent ↗A screwable vehicle antenna has a threaded part and a head part, which adjoins an end region of the threaded part. The threaded part and the head part both are made of electrically non-conductive material. At least one antenna radiator is arranged at least within part of the head part. A metal disk made of electrically conductive material is arranged on the head part and is used as a reflector or a ground plane. An HF electrical connector is provided, which is arranged on and fastened to a region of the head part remote from the threaded part, and the antenna radiator can be electrically connected to a plug of the HF electrical connector.
1. A screwable vehicle antenna, comprising:
a threaded part and a head part, which head part adjoins an end region of the threaded part, the threaded part and the head part both being formed from electrically non-conductive material;
at least one antenna radiating element, which is arranged at least within part of the head part;
a metal disk composed of electrically conductive material, which is arranged on the head part and is used as a reflector or a ground plane; and
an RF plug-in connector, which is arranged on and fastened to a region of the head part situated opposite the threaded part, wherein
the antenna radiating element is electrically connectable to a plug of the RF plug-in connector.
2. The screwable vehicle antenna according to claim 1 , wherein
the metal disk rests on the end region of the head part on which the threaded part is arranged.
3. The screwable vehicle antenna according to claim 1 , wherein
the metal disk is arranged at least partially within the head part.
4. The screwable vehicle antenna according to claim 1 , wherein
a mounting sleeve is formed around the head part, or the head part is formed in a prescribed shape.
5. The screwable vehicle antenna according to claim 1 , wherein
the thread is a self-tapping thread.
6. The screwable vehicle antenna according to claim 1 , wherein
the thread is a non-self-tapping thread.
7. The screwable vehicle antenna according to claim 1 , wherein
the antenna radiating element provides V2X communication or near-field communication.
8. The screwable vehicle antenna according to claim 7 , wherein
the communication is Bluetooth or WLAN.
9. The screwable vehicle antenna according to claim 1 , wherein
the antenna is arranged in an interior of a vehicle.
10. The screwable vehicle antenna according to claim 1 , wherein
the antenna is arranged outside the vehicle.
11. The screwable vehicle antenna according to claim 1 , wherein
the antenna is used to connect two electrically non-conductive components to one another.
12. The screwable vehicle antenna according to claim 1 , further comprising:
a PCB arranged between the antenna radiating element and the RF plug-in connector, wherein
the PCB is provided with elements comprising an amplifier circuit or a matching network.
13. The screwable vehicle antenna according to claim 12 , wherein
an amplifier is provided, which is supplied with electrical power by a phantom power feed via a coaxial cable fastened to the plug.
