So an antenna picks up electromagnetic waves from a broadcast station, these radio waves are used to encode sound, and since they are photons they also carry a bit of energy. Transmitting power wirelessly would work like this except you'd use a higher frequency, probably microwave, and up the intensity significantly.
I think the idea is that it's not a tight beam at all, but rather a very diffuse and spread out signal that reaches an "antenna" that is basically a wire mesh covering several square miles.

You can tighten the beam an make a poor man's orbital beam cannon if you want though. So that is fun.
Yes, you are morally obligated to use this satellite to set the Gävle goat on fire each year.
