The invention also relates to an automatically tunable antenna array using this method. ... Tekcem

Method for automatically adjusting a tuning unit, and automatic tuning system using this method

The invention relates to a method for automatically adjusting a multiple-input-port and multiple-output-port tuning unit, for instance a multiple-input-port and multiple-output-port tuning unit coupled to the antennas of a radio transceiver using a plurality of antennas simultaneously. An automatic tuning system using this method has 4 user ports and 4 target ports, and comprises: 4 sensing units; a signal processing unit, the signal processing unit estimating real quantities depending on an impedance matrix seen by the target ports, using sensing unit output signals, the signal processing unit delivering a tuning instruction; a multiple-input-port and multiple-output-port tuning unit comprising adjustable impedance devices; and a tuning control unit receiving the tuning instruction and delivering tuning control signals to the multiple-input-port and multiple-output-port tuning unit, the reactance of each of the adjustable impedance devices being mainly determined by one or more of the tuning control signals.. ...

Method and apparatus for automatic tuning of an impedance matrix, and radio transmitter using this apparatus

The invention relates to a method and an apparatus for automatic tuning of an impedance matrix, for instance the impedance matrix seen by the power amplifiers of a radio transmitter using a plurality of antennas simultaneously. The apparatus has 4 user ports and 4 target ports, and comprises: 4 sensing units; a signal processing unit which estimates real quantities depending on the impedance matrix presented by the user ports, using the sensing unit output signals obtained for 4 excitations applied to the user ports, two or more of the excitations being applied simultaneously, the signal processing unit delivering a tuning instruction; a multiple-input-port and multiple-output-port tuning unit comprising adjustable impedance devices; and a tuning control unit receiving the tuning instruction and delivering tuning control signals to the multiple-input-port and multiple-output-port tuning unit, the reactance of the adjustable impedance devices being mainly determined by the tuning control signals.. ...
