A wearable computing device can include a monopole-excited slot antenna formed by a gap between a housing (such as a highly conductive housing) and a bracket (such as a highly conductive bracket) within the highly conductive housing and by a back cavity between the highly conductive bracket and the PCB. The antenna configuration can include a monopole antenna electrically coupled to a printed circuit board and a slot antenna that is excited through coupled electromagnetic fields. The highly conductive bracket is positioned near a display window of the device, mostly below and partially enclosing a battery. The highly conductive bracket is positioned above the printed circuit board. This configuration allows for a relatively small dead band in the display window, a larger battery, compact and mechanically simple configuration, and superior water resistance.

Methods for slot antenna design for wearable electronic devices and conductive housings

Mechanisms for providing inductance-based user interface elements are provided. Some implementations of such inductance-based devices may feature very small gaps between the housing and the inductive coil, as well as various features to aid in improving sensor sensitivity and reducing the possibility of false button-push events.
