Well, many of the users of the Apple iPhone 6 and the iPhone 6 Plus have some of the issues with the antenna lines of the handset as they were getting discolored by sliding the handset in and out of the jeans pocket. The company now seems to get rid of the antenna lines issue that are necessary to get the radio signal through the anodized metal used on the iPhone 6 and the iPhone 6 Plus. Taking a step forward in this direction, the Cupertino giant has recently filed an patent with the USPTO for a new metal like material which has the same look and fell as to the one used in the latest iPhone. However, this new material will allow the radio signals to reach the components inside the handset and with the same transparency allow them to let them through.
The patent shows up different ways that Apple could imitate this anodized metal. One of the ways is depositing a non-capacitive layer on the top of a metal oxide layer. Another way is to imitate the metal oxide layer and then cover it non-capacitive layer. Below is what the Apple’s patent application reads.
“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.”
However, there is no guarantee of Apple using this filed patent method in their next iteration handset but it certainly gives users the ray of hope to overcome the antenna lines issue.
