Abstract (en)
[origin: EP2975688A1] An antenna feed for generating signals for an active antenna array including multiple antennas for transmitting transmission beams having selected tilt angles, the antenna feed comprising a digital beamformer operable to receive an input broadband signal and to generate a plurality N of output broadband signals, each having an associated phase and amplitude, a plurality N of transmission signal generators, each operable to receive one of the said plurality N of output broadband signals and to generate a corresponding plurality N of first RF signals, and a feed network comprising a power split network operable to receive the said plurality N of first RF signals and to generate a plurality P of second RF signals, each having an associated amplitude and an associated phase shift applied using a variable phase shifter of a phase shift network, the feed network operable to supply respective ones of the plurality P of second RF signals to respective ones of the multiple antennas, M, of the said active antenna array, where P‰¥M>N.
