At the risk of sounding like a complete idiot: can't they send on slightly different frequencies or wavelengths? Or: why don't they just copy the design of ante

  Antennas on mobile phones need to be designed to take into account the environment around them - other chips, other antennas, metal body of case work, likely position of head relative to phone. They are customised to the particular application. Trying to design one that will work regardless of the combination of other components chosen is a difficult challenge.

    Sort of. Mass market radios are designed for low cost and low power consumption, and the engineering cost is amortized over tens of millions of devices. For that market segment it makes sense to make a perfectly customized radio. There's nothing to stop them from putting a self-tuning phased-array radio on a niche product. At $50 a unit extra on a volume of 200,000 it might be viable. And the tech could be amortized over a line of industrial radios too.
