Abstract
A vehicular antenna system uses a plurality of vehicle windshield wipers. Each wiper is configured to act as an antenna receiving element. The wipers may be configured to act as receiving elements by using a conductive wiper housing and/or a conductive spring. Insulators are positioned to electrically isolate the antenna receiving elements from vehicular ground. In one embodiment, an insulating bushing is positioned within a windshield wiper housing aperture so that the entire wiper is isolated from a wiper shaft.
Claims15
In a vehicle having a wiper shaft electrically connected to a vehicle ground, a vehicular antenna system comprising:
- a vehicular windshield wiper;
- an antenna signal conductor connected to said wiper;
- and
- an insulator coupled to said wiper said insulator being configured to electrically insulate said vehicular windshield wiper from said wiper shaft so as to prevent grounding of received radio signals to said vehicle ground.
In a vehicle having a windshield, a vehicular antenna system comprising:
- a vehicular windshield wiper having a wiper housing configured to retain a wiper element;
- a conductive spring located in said wiper housing, said spring serving as an antenna receiving element, and said spring serving to urge said wiper element toward said windshield;
- and
- an antenna signal conductor connected to said spring.
In a vehicle, a vehicular antenna system comprising:
- a first vehicular windshield wiper having a first conductive housing configured to serve as an antenna receiving element which receives first radio signals;
- a first insulator coupled to said first housing;
- a first antenna signal conductor electrically coupled to said first housing so as to conduct said first radio signals, said first conductor being coupled to said first insulator so as to prevent grounding of said first radio signals to said vehicle;
- a second vehicular windshield wiper having a second conductive housing configured to serve as an antenna receiving element which receives second radio signals;
- a second insulator coupled to said second housing;
- a second antenna signal conductor electrically coupled to said second housing so as to conduct said second radio signals, said second conductor being coupled to said second insulator so as to prevent grounding of said second radio signals to said vehicle;
- and
- means, coupled to said first and second antenna signal conductors, for consolidating said first and second received radio signals conveyed by said first and second antenna signal conductors, respectively.
