Abstract: Various aspects of the disclosure are directed to steering antennas for receiving signals. As may be implemented in accordance with one or more embodiments, an apparatus includes two or more antennas that receive radio signals, a first circuit that directs the antennas and a second circuit that combines signals received by the antennas. The first circuit operates in a first mode by electronically directing the antennas using an analog portion of received signals to modify a radiation pattern of the receive antennas, based on estimated phase-shifts and/or estimated amplitude of the signals. In a second mode, the first circuit uses a digitally-modulated portion of the signals to electronically direct the antennas by modifying the radiation pattern of the receive antennas based on at least one of estimated phase-shifts and estimated amplitude of the signals. Accordingly, null-steering can be effected to eliminate interference.
