Abstract: Systems, methods, and apparatuses, including electronic devices and computer-readable storage media, for adaptively switching wireless connections between antennas of a wearable electronic device and a host electronic device. One device includes a wearable electronic device with a first and second housing, each housing including two or more antennas. The wearable electronic device is configured to establish and monitor a wireless cross-link between two antennas in different housings, or between antennas in one housing and antennas of a host electronic device. The wearable electronic device can monitor the integrity of the wireless cross-link, and establish an updated cross-link in response to the wireless cross-link not meeting a predetermined integrity threshold. The wearable electronic device can monitor a wireless cross-head link between housings of a wearable electronic device at the same time as a wireless cross-body link between the wearable electronic device and the host electronic device.

Abstract: 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.

Abstract: An augmented reality (AR) or mixed reality (MR) eyewear display utilizes an antenna arrangement for eyewear that optimizes the performance of the antenna without sacrificing the functionality or modularity of the eyewear. In one implementation, the antenna arrangement includes a first conductor that functions as a ground for the antenna, a second conductor configured to help retain a lens, and an antenna feed configured to excite the second conductor, causing the second conductor to act as an antenna. The first and/or second conductor additionally acts as a lens retention feature by interfacing with a groove in a lens and the use of a locking clip that prevents the lens from becoming dislodged from the second conductor, thus enabling quick and easy installation or removal of the lens.

Abstract: A high permeability metal (mu-metal) shield is placed in close proximity of a main logic board (MLB) of a wearable device, such as an earbud, to reduce eNoise. Radio frequency current flow induced by an antenna radiator will flow over the MLB and its associated ground plane, including the mu-metal shield. To reduce an impact of the mu-metal shield on antenna performance, a coating process is done on the mu-metal shield, by developing a thin layer of high conductivity, low permeability copper or silver on top of the mu-metal.
