Abstract
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.
