A vehicular radar board includes a PCB having a first surface and a second surface. The first surface of the board includes a plurality of transmitter end-fire antennas and a first plurality of receiver end-fire antennas that are spaced apart by a first gap. The second surface of the board includes a second plurality of receiver end-fire antennas that are spaced apart by a second gap that is greater than the first gap. The board also includes a first RFIC positioned on the first surface and designed to control the plurality of transmitter antennas to transmit radar signals and to receive a first reflected signal of the radar signals from the first plurality of receiver antennas. The board also includes a second RFIC positioned on the second surface and designed to receive a second reflected signal of the radar signals from the second plurality of receiver antennas.
