The Luneburg lens scanning antenna is optimized and is evaluated with two backing ground planes. Thebeam of the antenna is scanned as in a full or hemispherical lens antenna. The antenna weight is halved relative to thehemispherical lens as quarter of the lens is used. Simulations are conducted indicating a negligible scanning loss in boththe antenna principle planes. Lens design with electronic beam-switching using PIN diodes as switching element hasbeen proposed reducing the cost and complexity. Each switching state can be obtained by forward biasing one half of thediodes when the other half is reverse biased.
