ANTENNA DESIGN FOR ROBUST CROSS-HEAD AND CROSS-BODY LINK

摘要

The present disclosure provides a metal structure, or antenna radiator, for an accessory that is configured to function as both an antenna and an input control. The device may be a wearable device with a first surface shaped to be in contact with the human body and a second surface shaped to be exposed when the device is being worn. The antenna radiator may be located internally within the housing of the device and coupled to a printed circuit board ("PCB"). The PCB may be located between the antenna radiator and the surface of the housing such that the PCB may shield the antenna radiator from antenna loss due to the human body. An electric field may extend between the PCB and the antenna radiator. The fringe electric field may improve cross-head and cross-body connectivity between the accessory and another device.
