Sony patents antenna design that blocks noise from internal components
Sony describes an electronic device that uses a specific metal shape to stop unwanted electrical signals from interfering with wireless communication. The design places a conductive piece with a small projection in the path of the noise, sized to disrupt the signal before it reaches the antenna.
In the filing’s own words
Provided is an electronic device including an antenna for performing wireless communication, a noise source that causes generation of radiation current, and a conductive member that is disposed on a propagation path of the radiation current from the noise source to the antenna and has a projecting portion projecting from the propagation path. An electrical length to a tip end of the projecting portion is equal to or larger than one-eighth but equal to or smaller than three-eighths of a wavelength used in the wireless communication.
What exactly they claim (claim 1)
1. An electronic device comprising: an antenna for performing wireless communication; a noise source that causes generation of radiation current; and a conductive member that is disposed on a propagation path of the radiation current from the noise source to the antenna and has a projecting portion projecting from the propagation path, wherein an electrical length to a tip end of the projecting portion is equal to or larger than one-eighth but equal to or smaller than three-eighths of a wavelength used in the wireless communication.
