You need certain oscillator geometries to interact with electromagnetic
radiation of a given wavelength. Look: http://www.ggrweb.com/article/gulley.html

No. This isn't about GPS, just about on-die radios. At a guess,
small-geometry (fractal) antennas are useful specially for UWB. Which happen
to provide positioning sevices, but are limited to ~10 km free space (much
less in cluttered environments) propagation. Good enough for terrestrial cellular
positioning service, though.

No known technology can change physical laws.
