Abstract

A radar sensor includes a housing of radar-transmissive material, a circuit board in the housing, first and second antennas of several patch elements on the same or opposite surfaces of the circuit board, and a metal or metallized support supporting a rear surface of the circuit board. The first antenna has a beam axis that extends out through a front of the housing at an angle in a range from 45° to 90° relative to the circuit board plane. The sensor further includes a beam deflection structure arranged within the housing to deflect a beam axis of the second antenna out through the housing at an angle in a range from 0° to 45° relative to the circuit board plane.
