Abstract
An antenna array for the transmission of signals is disclosed which comprises a plurality of antenna elements connected to a plurality of transceivers. The plurality of transceivers receive transceiver signals for transmission to the plurality of antenna elements. The antenna comprises a failure detector or monitoring and control system connected to the plurality of transceivers, which autonomously detects malfunction of the individual transceivers and reports this to the signal processor without involvement of the transmitter and receiver. The antenna array also comprises a signal processor connected to the plurality of transceivers and adapted to weight using complex values the transceiver signals for automatically compensating for power losses by tilt adjustments and for interference by suppression of sidelobes of the signals based on the information from the failure detector or monitoring and control system.
