1. A vehicle comprising:
- a controller configured to, responsive 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, wherein the controller is further programmed to size the aperture to have an inner diameter at least equal to one wavelength of electromagnetic radiation transmitted from the antenna.

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.

5. 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, responsive 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 (6, 7, 8, 9)
