Abstract
The invention relates to a method for automatically adjusting a plurality of tunable passive antennas and a multiple-input-port and multiple-output-port tuning unit. The invention also relates to an apparatus for radio communication using this method. An apparatus for radio communication of the invention comprises: 4 tunable passive antennas; a multiple-input-port and multiple-output-port tuning unit having 4 input ports and 4 output ports; 4 sensing units; 4 feeders; a transmission and signal processing unit, which applies 4 excitations to the input ports, one and only one of the excitations being applied to each of the input ports, and which delivers one or more antenna adjustment instructions and one or more tuning unit adjustment instructions; and a control unit, which delivers one or more antenna control signals to the tunable passive antennas, and which delivers one or more tuning control signals to the multiple-input-port and multiple-output-port tuning unit.
