Abstract: A metal chassis for a mobile device is configured to transmit a signal of a wavelength. A first side of the chassis faces the inside of the mobile device and includes a first aperture that has a dimension that comprises a first subwavelength width of a slot in the chassis. A second side of the chassis faces free space and includes a second aperture that has a dimension that comprises a second subwavelength width of the slot in the chassis. A channel connects the first aperture and the second aperture. The slot has a length dimension and the channel may be centered along the length dimension. The channel is configured to support a transverse electromagnetic mode for propagation of the signal from the first aperture through the channel to the second aperture. As a part of a mobile device the chassis acts as a secondary radiator for the mobile device.

Abstract: Generally, this disclosure provides systems, devices and methods for integration of millimeter wave antennas in platforms with reduced form factors while maintaining or improving antenna gain. An antenna assembly may include a first planar substrate; a ground plane disposed on the first planar substrate; a second planar substrate disposed on the ground plane; and an antenna radiation element disposed on the second planar substrate. The antenna radiation element may be configured to transmit a signal in the millimeter wave frequency region. The assembly may also include a via to provide a conductive path for the signal from a microstrip feed line, beneath the first planar substrate, to the antenna radiation element. The assembly may further include a dielectric layer disposed on the antenna radiation element to provide increased antenna gain under conditions of reduced air gap between the antenna radiation element and a structural element of an enclosing platform.

Abstract: A wireless head-mounted display (HMD) device to be worn on the head of a user includes a HMD body having a display device and a head-mount structure. Features of the HMD device, as well as in-situ operational configurations of the HMD system are described for supporting wireless communications with a content source situated at varying directions relative to the HMD device.
