Abstract
A system for beamforming, in a phased array antenna. Subtraction of a sinusoidal signal from a received signal, or from a signal to be transmitted, is used to shift the phase of the received signal, or from a signal to be transmitted. A separate sinusoidal signal may be generated for each antenna array element, making it possible to shift the phase on a per-element basis, to perform beamforming.
