So far, we have seen a few Microsoft patent applications suggesting the presence of a mysterious Surface Phone.
If you can remember, a few months ago, Microsoft CEO Satya Nadella announced that 2017 would see Microsoft launch the ultimate mobile device saying, "We will continue to be in the phone market not as defined by today's market leaders, but by what it is that we can uniquely do in what is the most ultimate mobile device." In July, a patent titled 'Wireless Communications Device' surfaced online.
Now, we have come across a new patent titled "Cover of Device Acting as Antenna of the Device". There is a catch though, the patent was filed with the USPTO more than a year ago. The patent shows a metallic built handset. As suggested by the name of the patent, the metallic also functions as the antenna.
Apparently, the device would swing around a hinge placed at the center of the handset, so users would not cause interference or the "detuning" that happens when their hands touch the antenna while in the process of using the handset.
When this "detuning" occurs, signal strength goes down and the blame is put on the users for holding the device incorrectly.
The patent is designed by Antti Karilainen, who is an antenna and RF expert. He has previously worked on some antenna and mobile based projects at Microsoft.
However, you must keep in mind that as with many cases, we may not get to see the Microsoft device at all. Even if it does, the phone wouldn't get revealed before 2018.
