Description.

The MIMOmatch-F portfolio consists of the inventions P64, P71 and P72 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 accurate open-loop control scheme, which provides a very fast automatic tuning of an antenna tuner, 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 P71 and P72, 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.

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