Apple applies for patent for metal-looking material that allows better reception

A lot of Apple iPhone 6 and Apple iPhone 6 Plus find the plastic antenna lines unsightly, especially when the dye in your jeans ruined the colour of these lines. Although an eyesore, these bands are essential, since they allow for better reception. If a patent application sees the light of day, you may never have to worry about this again.

Filed with the USPTO (US Patent & Trademark Office), Apple wants to patent a material that looks and feels like metal, but is not. The material will allow for a more seamless design that allows better phone signal.

Patent:

“NON-CAPACITIVE OR RADIO FREQUENCY-TRANSPARENT MATERIALS WITH ANODIZED METAL APPEARANCE”

Abstract:

“Composite structures that have an appearance of an anodized bulk metal but that is non-capacitive and/or radio frequency (RF) transparent are disclosed. The composite structure can be part of an enclosure of an electronic device. The composite structure can give the enclosure a metallic look without interfering with the functioning of some electronic components of the electronic device, such as RF antennas, touch pads and touch screens. Some embodiments involve forming a metal oxide layer and depositing a non-capacitive layer on the metal oxide layer. Some embodiments involve forming an imitation metal oxide layer and depositing a non-capacitive layer on the imitation metal oxide layer.”

Claim:

“A method of forming a composite structure, the method comprising: converting a portion of a metal substrate to a metal oxide layer such that a first surface of the metal oxide layer overlays an unconverted portion of the metal substrate, wherein the metal oxide layer is characterized as being substantially optically translucent; exposing the first surface of the metal oxide layer by removing the unconverted portion of the metal layer; and forming the composite structure by applying an optically reflective layer that is substantially non-electrically capacitive on the exposed first surface of the metal oxide layer, wherein the composite structure has an appearance of an anodized metal when viewed from a second surface of the metal oxide layer opposite the first surface.”

Note that not all patents see the light of day, which means we may not see this technology in the next iPhone.
