Classification: CPC H | IPC H

Claim 1:
2. The method of claim 1 wherein the first selected pair of Tx antenna elements comprises Txi and Txk, wherein i≠k;
the two or more pairs of Rx antenna elements comprise Rxn and Rxm; the at least one relative gain value and the at least one relative phase value for the Tx antenna element Txi relative to the Tx antenna element Txk is computed based on one or more of:
the gain measurement, GMTxiRxn, and the phase measurement, ϕMTxiRxn, for the pair of Tx and Rx antenna elements Txi and Rxn;
the gain measurement, GMTxiRxm, and the phase measurement, ϕMTxiRxm, for a pair of Tx and Rx antenna elements Txi and Rxm;
the gain measurement, GMTxkRxn, and the phase measurement, ϕMTxkRxn, for a pair of Tx and Rx antenna elements Txk and Rxn; and
the gain measurement, GMTxkRxml and the phase measurement, ϕMTxkRxm for a pair of Tx and Rx antenna elements Txk and Rxm;

repeating the steps of determining and computing for at least one second pair of Rx antenna elements, Rxn and Rxm, having symmetrical coupling properties with respect to the pair of Tx antenna elements, Txi and Txk.
