Abstract
Various antennas elements including antennas arrays can support various communication technologies and can be integrated into different components or subcomponents of a vehicle, including various vehicle light assemblies. The vehicular antennas elements include low profile and/or concealed antenna elements that are inconspicuous aesthetically and do not affect or substantially affect vehicle aerodynamics.
Claims20
A retro-directive antenna array system for wireless communications comprising:
- an antenna array comprising one or more antenna elements;
- a negative refractive-index engineered material (NIM) deposited over at least one of the one or more antenna elements;
- and
- a controller configured to control a switch configured to connect the one or more antenna elements to a transmission path and to a reception path,
- wherein the NIM has a tunable surface configured to be adjusted by the controller via application of a stimulus into a negative refraction mode when the one or more antenna elements are connected to the reception path and to be adjusted into a positive refraction mode when the one or more antenna elements are connected to the transmission path.
A retro-directive antenna array system for wireless communications comprising:
- an antenna array comprising one or more antenna elements;
- a negative refractive-index engineered material (NIM) deposited over at least one of the one or more antenna elements;
- and
- a controller configured to control a switch that is configured to connect the one or more antenna elements to a transmission path and to a reception path,
- wherein the antenna elements comprise a dual-polarized antenna with a first polarity in a reception direction for signals received by the retro-directive antenna array system and a second polarity in a transmission direction for signals transmitted from the retro-directive antenna array system, wherein the first polarity and the second polarity are different, and wherein the NIM has a tunable surface configured to be adjusted, via application of a stimulus, into a negative refraction mode when a current polarity of the dual-polarized antenna is in the reception direction and to be adjusted into a positive refraction mode when the when the current polarity of the dual-polarized antenna in the transmission direction.
