Apple Invents Material That Looks Like Metal and Could Rid iPhone of Unsightly Antenna Bands



Apple has filed a patent application for a non-capacitive or radio frequency-transparent material with an anodized metal appearance. Most notably if used for the casing of the iPhone, this type of material would let Apple get rid of the 'unsightly' antenna bands.

Apple says that "one design challenge associated with computing devices is maintaining a sleek and consistent appearance of a metallic outer enclosure for housing the various complex internal components."

Since metal is not radio frequency transparent, portions of the housings that cover antennas and touch sensors are made out of non-metallic materials such as plastic or glass. "Unfortunately, plastic surfaces and glass surfaces have different visual qualities than metallic surfaces, which result in a visible break in the metallic surface of the housing. This visible break can detract from the smooth and continuous look of the metallic housing."
