Answer is simple and clear that Apple has filed for a patent on a composite material that looks like anodized metal, but still allows wireless signals to get through. With USPTO, Apple has invented a new material that could be used for future phones, which by using it can even hide the antenna lines on the iPhone.
Apple with a new patent application published on Thursday gives the clearest indication yet the future iPhones will benefit from a new and improved antenna setup. Within it, the company outlined fairly comprehensive plans to invest in the design and development of a new composite matel material that will almost look and feel exactly like regular metal with an anodized finish. Difference only be the forms the main part of the patent application, that the new material will be capable of allowing radio frequences to pass seamlessly throught it, and making it the perfect setup to hide the antenna on a mobile device.
No doubt that people experience the premium feel of unibody metal gadgets, but a metal exterior brings about a set of challenges, especially on a mobile phone, as wireless radios of all sorts, like your network modem, Wi-Fi and NFC won’t take a complete metal enclosure too well and aren’t about to be swayed to play nice with it based on it look alone.
Apple, along with biggies in the smartphone game, has long been searching for new and improved ways of integrating radios into its design and manufacturing processes. Antenna, or a Bluetooth chip for that matter, is to allow some kind of external connection to other devices. It could be a cell tower, or a secondary Bluetooth compatible device, or even a payment terminal in a store. By means, the design of the radios and integrated chips obviously require the ability to penetrate the external material of the device in order for it to do it job perfectly.
The Cupertino giant has found a way to address the issue and created a clever engineering solution, like the infamous plastic antenna lines on the back of iPhone 6, or similar inserts on the HTC One M9, Apple has apparently created and filed a patent for a new composite material that looks exactly like adonized metal and still lets radio waves pass through. Presumably, the idea behind the new patent application is to produce a composite metal that the company can use in its manufacturing processes to give the next generation of iPhones a flawless design pattern.
Currently, both the iPhone 6 and iPhone 6 Plus will have two plastic strips along the top and bottom of the rear of the device. Strips have been elegantly incorporated into a design of the product, and still needed to allow the antenna system to function efficiently. While the aspects of the patent filing is not the fact that Apple has actually gone to great lengths to develop a new material, but this is the company that redesigned gold for the Apple Watch Edition. In fact the company clearly sees the material being used frequently throughout its range of iPhones, iPads and Macs.
Future iPhones could indeed ditch plastic antenna bands for anodized material. Companies like Apple often hold multiple of thousands of patents that actually never see the light of day by making it into a real product. Hopefully we will see the new technology employed in the next line of iPhones, and seems to a definite real world use case for this one to stand the test of time.
