A beam steering system includes a differential segmented array (DSA) antenna comprising a plurality of pyramid structures and elements arranged in an array comprising a first and second set of direction elements, where each element is defined between opposing faces of two adjacent pyramid structures and a position of each element is located at a distance from a common origin of the elements of the array; phase gradient determination circuitry to determine a first and second phase gradient for the direction elements, where the phase gradients are based on a first and a second angle of a target with respect to the DSA antenna, and an operating frequency of the DSA antenna; and phase shift determination circuitry to determine a first and second phase shift, for each of the elements, and to determine a resultant phase shift, for each element, by summing the respective first and second phase shifts.
