Now, I am sure at least some of you have heard of this technology that Nokia is developing. It creates around 5 mW right now. My question is, how do you make an antenna that small pick up that many frequencies/wavelengths? What if I wanted to build one?
I apologize if any of this is a dumb question, my EET degree hasn't dabbled much in communications...at least not yet.
