Description.

The MIMOmatch-G portfolio consists of the inventions P65, P66, P73 and P74 of Tekcem, which belong to the space "adaptive antenna tuning for a wireless device using one or more antennas". The inventions of this portfolio have the following characteristics:

they use an antenna tuner and are suitable for user equipments (UEs) of wireless networks;
they use an open-loop control step, followed by an extremum-seeking control step providing an accurate maximization of output power and efficiency during emission, over a broad frequency range;
they adaptively compensate the effects of the electromagnetic characteristics of the surroundings (including the so-called user interaction), to deliver an optimal automatic tuning, even when antenna tuner losses are significant;
they explicitly cover uplink and downlink antenna selection techniques.

In the patent families P73 and P74, a preliminary automatic adjustment of the one or more tunable passive antennas used for radio communication provides a coarse tuning, and is followed by an automatic adjustment of the antenna tuner providing a fine tuning. In this way, an accurate adjustment of the antenna tuner can be obtained over a much broader frequency range than with one or more non-tunable antennas, and faster.

A detailed presentation of the MIMOmatch-G portfolio is posted here. The contents of the MIMOmatch-G portfolio is subject to change without notice.
