Sidelobe suppression in 76-GHz post-wall waveguide-fed parallel-plate slot arrays.

Sidelobe suppression is demonstrated for 76-GHz post-wall waveguide fed parallel-plate slot arrays for car radar applications. Taylor distribution illumination control is successfully confirmed experimentally in the slot array on the parallel-plate waveguide. The amplitude distribution in the transv...
