A retro-reflective patch antenna has been developed for radar-based vehicle following. Radar scattering from vehicles is strongly angle dependent at frequencies of practical interest, which complicates tracking. The antenna described here provides a strong, angle independent return that can be used as a stable aiming point. The antenna is a planar Van Atta array of dipoles with a multilayer stripline feed. The antenna's size is comparable to a license plate, and it can be directly attached to the back wall of a van or truck. A description of the antenna's design issues and measurements of its RCS are presented. The antenna described here is a microwave analog of the optical retro-reflector, and we expect it to find applications in many areas.
