Abstract
The invention relates to a method for automatically adjusting a plurality of tunable passive antennas, for instance a plurality of tunable passive antennas of a radio transceiver using several antennas simultaneously. The invention also relates to an automatically tunable antenna array using this method. An automatically tunable antenna array of the invention has 4 user ports, and comprises: 4 tunable passive antennas, the 4 tunable passive antennas operating simultaneously in a given frequency band and forming a multiport antenna array; 4 sensing units; 4 feeders; a signal processing unit delivering a tuning instruction; and a tuning control unit, the tuning control unit receiving the tuning instruction from the signal processing unit, the tuning control unit delivering tuning control signals to the tunable passive antennas, the tuning control signals being determined as a function of the tuning instruction.
