Here's the crazy dual antenna tuning tech that made the bezel-less Nubia Z9 possible

This probably isn't immediately apparent, but accomplishing the Asian monster that is the new Nubia Z9's virtually bezel-less screen was a nightmare for the engineers who had to fit an antenna in this thing, and make it work. The smartphone's screen extends to the very edges of the device, which leaves the antennas with little room to work. A tradtional antenna design wouldn't have cut it for the non-traditional Z9, hence ZTE recruited Cavendish Kinetics's high-performance RF MEMS tuning solution. So the Nubia Z9 ended up as the world's first smartphone to use Cavendish’s SmarTune™ tech. This is a dual antenna tuning approach that uses two independent tuners. It's based on small, highly efficient narrow-band antennas, rather than traditional wide-band ones, which lets the Z9 attain optimal performance across all LTE frequencies. This wouldn't have been possible with wide-band antennas.
