While embedding an antenna in the external body of an iPhone may not have been Apple’s best idea, hiding it behind the logo may be a little better thought out.
Per PatentlyApple, that’s the idea Apple wrote up in a patent application dated June 17th, 2009, back before we knew antennas and gates could be so wickedly conjoined.
This idea was also used for iMacs, which also have antennas peering through an apple-shaped hole to avoid any reception issues caused by an aluminum chassis. It looks to be a good solution, but not exactly a novel one. The idea was also incorporated in a similar 2003 patent from Dell also called “Logo Antenna,” the big difference being that while Apple’s logo forms a window for the antenna the logo in Dell’s patent actually is the antenna.
