Abstract
Disclosed is a hybrid antenna array () comprising a plurality of digital branches (), each digital branch including an analogue beamforming sub-array (e.g.-), each sub-array having a plurality of antenna elements (), a phase shifter () adapted to apply a phase shift to the signal from each antenna element, and a combiner (e.g.-) adapted to combine the phase-shifted signals. Each digital branch also includes a signal chain (e.g.-) adapted to convert the output of the sub-array to baseband. The hybrid antenna array also comprises a digital processing module (), including: an angle of arrival estimation sub-module () adapted to estimate an angle of arrival of a signal at the antenna elements; a phase control sub-module () adapted to control the phase shift applied by each phase shifter depending on the estimated angle of arrival; and a digital beamformer () adapted to combine the baseband signals from the digital branches using a weight vector to form an output signal ().
