This article has some excellent information, thanks so much for it.
I always wondered what happened to the antenna that used to be attached to every cell phone. I definitely remember the huge cell phones that were as big as your face when you held them up to your ear. The antennas on those phones were so flimsy. I must have broken at least two or three of them off my phones.
I always thought that technology had developed so much that antennas were no longer needed on cell phones. I never thought that manufactures had actually built the antennas into the phones.
Thinking that shows how little I actually know about cell phone technology. Thanks for schooling me! I will now go and surprise my husband on how much I have learned.
