1. A vehicle comprising:
- a conductive housing surrounding an antenna and defining an aperture having a size at least equal to a wavelength of signals radiated by the antenna; and
a controller configured to, in response to receiving a cooperative control signal from a platooned forward vehicle, orient the housing to point the aperture in a direction opposite the forward vehicle, and after relaying the signal, orient the housing in a direction toward the forward vehicle.

Abstract
A vehicle may include a conductive housing surrounding an antenna and defining an aperture having a size at least equal to a wavelength of signals radiated by the antenna. A controller may be configured to orient the conductive housing to direct the aperture at a direction of travel to guide electromagnetic radiation from the antenna. The controller may orient the conductive housing in response to receiving a cooperative adaptive cruise control signal from an established platoon of vehicles.

6. A vehicle comprising:
a controller configured to, in response to occurrence of a vehicle event while the vehicle is participating in a platoon, orient a conductive housing having an antenna therein to point an aperture defined thereby in a direction opposite vehicle travel to transmit data via the antenna about the vehicle event to a following vehicle of the platoon, and thereafter orient the housing to point the aperture in a direction of vehicle travel. - View Dependent Claims (7, 8, 9, 10)

11. A traffic system comprising:
-
a conductive housing having a diaphragm defining an aperture with a diameter greater than one wavelength of electromagnetic radiation transmitted by an antenna therein; and a controller configured to, in response to receiving a request to change a traffic indicator, orient the housing to point the aperture in a direction of oncoming traffic affected by the request to direct transmissions via the antenna about the change to vehicles in the oncoming traffic. - View Dependent Claims (12, 13, 14, 15)
