It will be interesting to see/do a teardown of this. I'm wondering if the UWB is separate from the Bluetooth (which I assume is 5.0), though it's probably in a single ASIC.

This claims the UWB is at 6 and 8 GHz, but they fail to show the antennas.

Now we see that Apple patents slot antennas; what a load of shit:
