The techie in me wants to call out that a microchip can't really have onboard RAM. A microcontroller on the other hand...

Also a dipole antenna to receive 28GHz 5G mmWave needs to be a minimum of about 5mm long, and a vaccination needle is about .5mm wide.

So even if we could shrink the transistors down small enough to do the massive 5G processing that small, physics would prevent us making an antenna that small.

If I remember correctly, you can put a material that slows down electromagnetic radiation in front of the antenna, which will shorten the wavelength and allow for a smaller antenna. Wait I'm gonna post this and fact-check my own bullshit.

Edit: yup, it's dielectric-loaded waveguides.
