Does iPhone 11 device contain multiple UWB receivers?

Angle of Arrival (AoA) is often required for many applications for UWB enabled devices. I wonder if modern UWB enabled devices i.e. iPhone 11 contain multiple UWB receivers to support AoA or not?

These systems use multiple antenna, not multiple distinct radios to compute angle of arrival based on time of arrival at each antenna.

It's probably worth noting that these radios tend to be SDR (software defined radios) which detect signals by doing frequency analysis on a whole chuck of spectrum, rather than running to a specific frequency. This makes ToA and AoA calcs relatively easier than trying to sync a high rate time source across multiple radios
