This document describes a multimode high-isolation antenna system and associated methods and systems. The described antenna system is implemented on a generally-circular printed circuit board and can be used for wideband and ultra-wideband applications. The multimode high-isolation antenna system includes two orthogonal antennas separated by a decoupling structure. This arrangement provides high isolation between the antennas and enables five unique resonant modes of operation for the multimode high-isolation antenna system.

Multimode high-isolation antenna system

The present disclosure describes aspects of an antenna-in-package (AiP) transceiver module and associated methods and systems. In aspects, an AiP transceiver module includes a substrate of dielectric material and first and second layers of conductive material disposed on respective surfaces of the substrate. The first layer of conductive material disposed on a first surface of the substrate includes an antenna element and antenna feed pad to which a contact of a transceiver integrated circuit die is coupled. The second surface of the substrate includes a dielectric interface area that is opposite to an area on the first surface of the substrate in which the antenna element is disposed and excludes the second layer of conductive material. The dielectric interface area of the substrate may effectively increase an amount of dielectric material below the antenna element, such that a volume of the dielectric material includes an air gap below the module.

This document describes a dual-antenna system for a video-recording doorbell and associated devices and systems. The described antenna system may be implemented on an elongated printed circuit board and can be used for wideband and ultra-wideband applications. For low-cost devices, the dual-antenna system may implement diversity antennas by including first and second substantially orthogonal antennas connected to a chipset configured for single-input single-output (SISO) functionality. The dual-antenna system described herein achieves high antenna isolation and efficiency without a decoupling structure between the first and second antennas. Further, the dual-antenna system achieves high isolation while in proximity to a battery (e.g., a battery within a housing of a battery-powered, video-recording doorbell) and a metal plate for mounting the device to a wall or other structure.

A device is provided that includes (a) an antenna that includes at least one conductor, (b) a housing that includes an inner-upper surface and an inner-lower surface separated by a first distance, (c) a battery disposed within the housing, where a base surface of the battery is proximate to the inner-lower surface of the housing, where a first portion of the battery has a height, which is substantially equal to the first distance, and where a second portion of the battery is of lesser height than the first portion of the battery such that space exists between the second portion of the battery and the inner-upper surface of the housing, and (d) where the one conductor is arranged over the second portion of the battery in the space, such that the one conductor and the battery do not contact one another, and where, as arranged, the antenna is capable of a far-field communication.

A wireless device can include an antenna element, a printed circuit board, an antenna feed, a conductive surface, and a conductive connector. The printed circuit board can have a ground plane. The antenna feed can be connected, at a first point, to the antenna element and to the ground plane. The conductive surface can be disposed substantially parallel to the ground plane. The conductive connector can be connected, at a second point, to the ground plane and to the conductive surface. A distance between the first point and the second point can be substantially equal to one quarter of a wavelength of an electromagnetic wave to be exploited by the wireless device. At all other points, the ground plane and the conductive surface can lack a conductive connection between the ground plane and the conductive surface.

Embodiments describe a semi-transparent or transparent module antenna assembly disposed on a transparent portion of a user wearable device (e.g., a head wearable display or a smartwatch). Embodiments describe semi-transparent or transparent antenna assemblies disposed on portions of a wearable computing device not in direct contact with the user when the device is worn to increase the antenna's efficiency for receiving radio signals and to decrease the radiation absorbed by the user's body. Furthermore, the antenna is disposed on a transparent or semi-transparent surface to further increase the antenna's efficiency. For some embodiments utilized by head wearable displays, the portion of the device including the semi-transparent or transparent antenna assembly may be the optical system, which includes a transparent portion (e.g., a prism) for displaying CGI to a user; in other embodiments, the head wearable display including the semi-transparent or transparent antenna assembly is the lens.
