A novel and useful radome suitable for use in an automotive radar system that employs patch antenna arrays. In one embodiment, the radome is a ‘U’ shaped half cylinder for patch antenna arrays such as on a printed circuit board (PCB). The patch antennas may or may not be situated in the same plane. Each array has its own half cylinder associated with it. Each array may have a different antenna pattern with different gain and side lobes. In this case, each patch antenna array has its own radome configured appropriately. Alternatively, the radome comprises a half sphere shape (or bubble shape) whereby each antenna port has its own individual half sphere shaped radome. This functions to improve the performance of the radome by increasing the number of curved dimensions from one to two.
