    Abstract: An antenna system operates in a hybrid coplanar waveguide and rectangular waveguide mode. A slot array with a conductive layer is disposed on a substrate and defines a coplanar waveguide joining a number of side slots arranged in a line forming the slot array. Another substrate is spaced apart from the substrate and a ground plane is defined thereon. A defined volume waveguide is disposed between the substrates. The array is configured to radiate a radiation pattern in a hybrid mode that results from a combination of the slot array and the defined volume waveguide. The side slots may be elliptical in shape for side lobe level reduction.

    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.

    Abstract: A cargo lift system for a vehicle includes a frame system, a deck system, and a cargo hook. The frame system is configured to be attached to the vehicle. The deck system includes a deck frame having a plurality of deck frame segments. The deck system is operable to translate along the frame system in (i) a first deployment mode where the deck frame segments cooperate to define a rigid support platform and (ii) a second deployment mode where the deck frame segments articulate to a lift position adjacent to a ground surface associated with the vehicle The cargo hook is attached to the deck system and operable to move between an extended state and a retracted state.
