Antenna size is directly correlated to wavelength. Minimum antenna size for 5G signal is ~3mm. AFAIK there are some tricks to reduce that slightly, perhaps to 2mm. That's still 4-5 orders of magnitude beyond what is considered nanotechnology. Not gonna fit through the needle either.
How many nano particles do you need to align to reach 2mm? ...
He thinks that nobody can figure out that a variety of antenna designs work well even being less than a wavelength in size. Else an AM radio would have to be 300 meters long.

5th generation mobile network (or any other) is not limited to single wavelenght. Different carrier use differant signal depenting on target audience, longer wavelenght more coverage, higher pulserate need more towers and more susceptible to weather....
60Ghz (5mm) is open usage anyone can use same as 2.4Ghz (Router, bluetooth, wireless headphones....)
T-mobile 600Mhz and 2.5ghz
Sprint 800Mhz, 1.9Ghz, and 2.5Ghz
Verizon 28ghz and 39ghz
Corresponding full, 1/2 or 1/4 wavelenghts (what fraction can be done this days?)
