A method for determining presence of an object via a vehicular radar sensing system includes providing a radar sensor having a plurality of antennas, which includes a plurality of transmitting antennas and a 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. A radar beam is transmitted via the plurality of transmitting antennas and side lobes of the transmitted radar beam are reduced via the plurality of shaped sets of antennas. An output of the receiving antennas is communicated to a processor, and the processor determines presence of one or more objects exterior the vehicle and within the field of sensing of the radar sensor.
