This "Active Steering" technology by Ethertronics has been included recently in certain Dell laptops. It got its start in the WiFi world. Dell claims it has 40% improvement in reception. CNET says it will thoroughly test this antenna when it becomes available in the spring and thought the demo CM gave was "impressive." The CM marketing brochures seem to target this antenna for apartment and condo reception (indoors).
In an interview a CM rep mentioned that the antennas are "polarized" dynamically according to the perceived incoming radiation patterns. Aereo, the company the Supreme Court ruled against for distributing OTA signals through the Internet, had a similar concept for its antennas. Not quite sure what this "polarization" means but the concept of dynamically adapting reception according to the radiation pattern does occur in 5th generation LG tuner chips to combat multipath interference problems.
Fractal antennas are also meant to address this problem of reception waveforms, polarity of different frequencies, planes of radiation patterns, etc. Something ATSC 3.0 is meant to deal with to ease transmission\reception in urban environments. So OTA is far from dead as everyone seems to include the word "cordcutting" in their discussion and speeches.

BTW do I believe these claims of a silver bullet of an antenna? Or is it a marketing scam? My experience over three decades has been that there is no such magic antenna and my solution to my reception problems has been to install three different antennas at three different locations. But at least it's a start in CM's case to try and develop an antenna using different principles rather than just reconfiguring metal parts into different shapes LOL.
