Abstract
The invention provides an aerial for a motor vehicle having an aerial base portion which can be fitted onto the body of a vehicle, and is provided with a capacitive ground coupling. According to the invention, the aerial base portion, ground coupling, aerial wire and the connected end of the high frequency line are embedded in a single component elastomer body which is provided with a locking configuration for locking in an opening of a wall of the body of the motor vehicle.
Claims5
Aerial for a motor vehicle, of the type having a capacitive ground coupling and comprising:
- a disk shaped aerial base portion which can be positioned inside a vehicle body of said motor vehicle;
- an elongated aerial tip portion which extends from said base portion, and which in an installed position of said aerial extends through an opening in said vehicle body and projects away from said vehicle body;
- an aerial wire having one end connected to a shielded high frequency line and another end which is integrated into said elongated aerial tip portion and, in an installed position of said aerial, extends outwardly from said vehicle body;
- and
- a contact plate which is embedded in said disk shaped aerial base portion on an upwardly exposed surface thereof and which contacts a shield of said high frequency line for capacitive ground coupling;
- wherein
- said disk shaped aerial base portion and said elongated aerial tip portion comprise a single component elastomer body;
- a locking configuration is provided between said disk shaped aerial base portion and said elongated aerial tip portion for locking the elastomer body from inside said vehicle body in said opening therein, whereby said contact plate is electrically coupled with said vehicle body.
