Bureau of patents and trademarks U.S. registered patent application filed by Apple on new material that looks like anodized metal, but prevents the passage of the radio signal. Use when you create the iPhone will allow to refuse a glass or metal inserts, covering the modules antennas.
Since the metal does not transmit cellular signals, manufacturers of smartphones and tablets have to look for workarounds. So, the iPhone 6 and iPad models with LTE support on the rear panel is provided by a plastic insert.
“Unfortunately, plastic and glass surfaces look different from the metal surface, which creates a visual gap in the metal surface, – stated in the patent application Apple. – Visible inserts spoil the uniformity of the metal structure of the shell of mobile devices.
Apple found a way to create a special composite material that prevents the passage of the radio signal, but it looks like anodized metal. The patent describes a method of making such material:
“The method provides for the conversion of part of a metal layer on the layer of metal oxide. The original portion of the metal layer will be viewed through the layer of metal oxide. The method also includes the provision of a layer of metal oxide by removing the original part of the metal layer. Then, it creates a composite structure, with the result that the material ceases to block radio signals, but it continues to look like anodized metal.”
Patented Apple technology will allow for a more coherent from an aesthetic point of view, smartphones and tablets. Unfortunately, on possible terms of practical implementation of the idea has not reported.
