A new patent application published on Thursday gives the clearest indication yet that future iPhones will benefit from a new and improved antenna setup. Within the application, Apple outlined fairly comprehensive plans to invest in the design and development of a new composite metal material that will look and feel exactly like regular metal with an anodized finish. The only real difference, which forms the main part of the patent application, is that the new material will be capable of allowing radio frequencies to pass seamlessly through it, making it the perfect composite to hide the antenna on a mobile device.
