The New mmW “Porcupine” Channel Sounder from NI and AT&T is Missing Quills (Beams)! | Akbar Sayeed | Pulse | LinkedIn.
I am afraid this is a “wounded” porcupine – many of the quills (beams) are missing! Using a lens antenna array for the sectors (as in the CAP-MIMO prototype below developed at the UW-Madison) would make the porcupine whole again! With a lens array, each “sector” covered by a single horn antenna above, would be larger (to fill the gaps in coverage) and spanned by many beams (16 shown below) – thereby replacing the missing quills (beams)!
This is very disappointing coming from two industrial leaders – especially given all we know at this time! We can do a lot better!
