Abstract: A head mounted display (HMD) device includes a housing configured to mount on a face of a user, at least one display mounted in the housing, a wireless personal area network (WPAN) antenna mounted in a medial region of the housing, and first and second wireless local area network (WLAN) antennas located at respective lateral peripheries of the housing. The WPAN antenna includes a directional patch antenna comprising a feed line, a three-dimensional (3D) ground plane formed as a plurality of conductive sidewalls and a ground plane structure disposed at a first end of the sidewalls, wherein the ground plane structure is substantially perpendicular to the plurality of sidewalls. The WPAN antenna also includes a radiating surface disposed at a second end of the sidewalls opposite of the first end, wherein the radiating surface includes a patch antenna structure coupled to the feed line.

Abstract: A portable computing device may comprise a display, a frame, and a communication circuit. The frame may support the display. At least a portion of the frame may be electrically conductive, and the electrically conductive portion of the frame may define a slot. The communication circuit may be coupled to the slot. The communication circuit may be configured to generate a fringing field. The fringing field may include electromagnetic waves with a wavelength at least eight times a width of the slot in a widest direction of the slot.
