Apple could hide the antenna notch on the iPhone

Apple has patented a system that would permanently hide the antennas on future Cellular iPhones and iPads.

One of the design problems of the iPhone and iPad is making a version that can effectively handle electromagnetic waves, that is the signals sent and received by the antennas within mobile devices. Allowing the antenna to do its job means using materials that prevent blocking of a signal and allow for an opening from the enclosure to the outside world.

In the case of iPad, the back of the body is a single piece of metal, which offers neither the passage of the signal through a hole, nor the use of materials that minimize the noise to the antenna. One way to solve the problem is to use other materials, as Apple did with its iPad Cellular which, on the back, partly uses a different material than metal.

In this new patent, Apple explains how to create an enclosure that offers the electromagnetic benefits of a case made of two different materials, but manufactured in such a way that it looks like a single component. The same would also apply to iPhones, so from eliminate the notches found on the edges of the device.

Apple’s idea involves three elements: an empty section of the main material that takes up most of the body, a second part to be filled and ink. In short, Apple suggests that a layer of ink could be used at the junction to hide it from view.

While the main housing may continue to be made of metal, the secondary section may be made of a non-conductive material that does not obstruct electromagnetic waves, such as plastic. The second part of the envelope could potentially consist of multiple layers, including an outer layer selected for aesthetic or structural purposes.

Regardless of the construction, Apple suggests using two layers of ink to cover the joint. The use of two layers of ink is to ensure that the cover completely hides the notch or layer made of a material other than the main one.

Will this be the solution that will be adopted on future iPhones and iPads?
