Abstract
A beam steering system includes a differentially segmented aperture antenna comprising a plurality of pyramid structures arranged in an array, and a plurality of elements formed in an array, each element being defined between two adjacent pyramid structures; phase conversion circuitry to determine a phase conversion for each element, the phase conversion for each element being based on an angle of a target with respect to the element, and an operating frequency of the DSA antenna; transmit phase shift circuitry to apply a phase difference for each element based on the phase conversion, the phase difference steering the signal to the target so that the signal interferes constructively; and receive phase shift circuitry to apply a phase difference for each element based on the phase conversion, causing the signal to interfere constructively for a signal of interest, and suppresses an unwanted signal by steering the signal into a null.
