A vehicular radar sensing system includes a radar sensor disposed at a vehicle. The radar sensor includes a plurality of antennas, which includes a plurality of transmitting antennas and a plurality of receiving antennas. The radar sensor transmits multiple outputs via the plurality of transmitting antennas and receives multiple inputs via the plurality of receiving antennas. The plurality of antennas includes a plurality of sets of antennas, each set having a V shape or an X shape, and with each of the shaped sets of antennas having an apex. A signal feed is provided to the apex of each of the shaped sets of antennas. Outputs of the receiving antennas are communicated to a processor, and the processor, responsive to the outputs of the receiving antennas, determines presence of one or more objects exterior the vehicle and within the field of sensing of the radar sensor.
