Abstract: A multi-antenna ground plane structure in a vehicle includes a first ground plane to be electrically connected to a fascia chassis. The fascia chassis is a portion of the vehicle covered by a fascia. A first side of the first ground plane seats two or more antennas. The multi-antenna ground plane structure also includes one or more additional ground planes affixed to a second side, opposite the first side, of the first ground plane. One of the one or more additional ground planes is attached to one or more antennas such that the one or more antennas is oriented opposite an orientation of the two or more antennas seated on the first ground plane.
