Eli5: Do fields (magnetic, EM etc) radiate in a 360 degree (ball shaped type) manner or is it a “2D” movement?

Depends on the shape of the antennae, it’s an entire engineering field how to design antennae to achieve desired radiation patterns [https://en.wikipedia.org/wiki/Radiation_pattern](https://en.wikipedia.org/wiki/Radiation_pattern)

No antennae radiates in a perfect 360 though, that’s one of the reasons that modern radio devices often have many antennae, so that one antennae could cover the not so good directions of the others.
