Patently Apple details a new Apple patent which utilizes a push button antenna to “ensure high-quality wireless transmission and reception.” They note:
Although the antenna could be based on a push button design, it may also be designed to be activated via an icon on your media device UI.
That’s certainly an interesting feature. Should you enter New York City with your 4G iPhone, perhaps the OS activates the antenna to hop on a weak AT&T signal?
Patently Apple wonders if this design might hint at television signal usage as well. Many more illustrations here.
