A new patent shows that Apple Watch antenna can be moved to improve signal quality

Future versions of Apple watch can distribute its antennas across the wearable device's fuselage, including some wireless connection related antennas on the back shell to improve reception quality.The apple watch operates on a variety of different types of wireless signals, including managing signals from Bluetooth, Wi Fi, NFC, GPS, and cellular connections. Since these systems rely on accurately picking up different wavelengths, multiple antennas are required because one antenna may be effective for one signal but not for another.

In addition to finding space for all antennas, the number also means that they may interfere with each other, so the antenna position must be perfect. The U.S. Patent and Trademark Office on Tuesday awarded Apple a

For the antenna, Apple says it can embed an antenna resonant element in the substrate and multiple such elements on the opposite sides. These components can be connected to RF transceiver circuits that power things such as NFC, which is recommended in the application for RF signals above 10 GHz. A plurality of metal and dielectric layers can be stacked on the substrate, sandwiched between the substrate layers, and can be used to create antenna resonant elements. More layers can be applied to create RF transmission lines. This version can use protruding elements in the dielectric structure to hold antenna resonant elements away from sensor assemblies and circuit extensions to minimize interference.

In short, Apple's proposal is to install the antenna on the back facing layer inside the apple watch. Although this allows more space for the antenna to function without interference, it does keep the antenna away from the top surface of the apple watch itself, which would be the ideal location for the antenna if it did not interfere with the display. Apple envisions the layer as a ring, so it doesn't interfere with the heart rate sensor. It's not entirely a bad idea to place it near the back shell and wrist, because it does make the side of the apple watch shell without sensors and buttons an ideal place for radio signals to pass through.

Apple files a large number of patent applications every week, but there is no guarantee that these patents will appear in future products or services.
