  • Method of calibrating a group antenna
    Patent number: 6295027
    Abstract: A method of calibrating a group antenna with minimal effort includes sending a respective calibrating signal over corresponding transmitting branches (TX1, TX2, . . . , TXm) one after the other; detecting superimposed signal components coupled into respective individual antenna elements (A1, A2, . . . , Am) of the group antenna for each calibrating signal sent over the transmitting branches in the receiving branches (RX1, RX2, . . . , RXm) belonging to the respective individual antenna elements; deriving amplitude and phase variations of transmission functions of all transmitting branches (TX1, TX2, . . . , TXm) or receiving branches (RX1, RX2, . . . , RXm) relative to a transmission function of a reference transmitting or receiving branch from received signals including the superimposed signal components detected in the corresponding receiving branches (RX1, RX2, . . . , RXm) for all calibrating signals; and adjusting amplitude adjusting elements (ATX1, ATX2, . . .
