The Attempt at a Solution



A guess would be that, the frequencies of the radio transmissions should be kept small so that the signal has a large skin depth and is not absorbed by obstructions easily. I'm not too sure though. Is this right?

Not really, we utilize frequencies on all the spectrum regardless of the skin depth, we just adapt different techniques to deal with different parts of the RF spectrum.

As you go higher in frequency the signal tends to travel more on the surface.

So can you expect that some component of a circuit can depend on its the surface area?

I dont really understand your question...the aerial?

So if it is the ariel, what is the importance of skin depth?

So we want a very small skin depth so the aerial recieves the EM wave easilly and converts this into a current?
