On the first day of September 2011, the US Patent & Trademark Office published a patent application from Apple that reveals one of the possible next chapters for Apple's iPhone and iPad. While Apple's patent delves deeply into a new composite that will include a foam substrate formed of a plurality of foam cells, it's the intent behind this that's revealing. The new composite would accommodate a new antenna window for Apple's iPhone and iPad formed of RF transparent materials. As shown in our cover graphic, the new antenna window could take up as much as half the backside of an iPhone. The proposed antenna window would have a seamless backside line that would almost be invisible. The new antenna window design obviously departs from the iPhone 4's stainless steel antenna band which has been so controversial.
