Samsung patents ring that uses its battery as part of the antenna
Samsung has filed a patent for a smart ring that combines its wireless communication antenna with the device's battery. Instead of using a separate metal piece for the antenna, the design uses a pattern on the circuit board that works together with the battery's metal casing to send and receive signals.
In the filing’s own words
A ring device is provided. The ring device includes a battery assembly including a conductive portion, a printed circuit board including a conductive pattern, and a wireless communication circuit electrically connected to the conductive pattern. For coupling, the conductive pattern is spaced apart from and faces the conductive portion of the battery assembly. The wireless communication circuit is configured to transmit or receive a radio frequency (RF) signal by using the conductive pattern and the battery assembly.
What exactly they claim (claim 1)
1. A ring device comprising: a battery assembly including a conductive portion; a printed circuit board including a conductive pattern; and a wireless communication circuit electrically connected to the conductive pattern, wherein the conductive pattern faces and is spaced apart from the conductive portion of the battery assembly for coupling, and wherein the wireless communication circuit is configured to transmit or receive a radio frequency (RF) signal using the conductive pattern and the battery assembly.
