Abstract: The disclosed system may include a frame, a printed circuit board (PCB) mounted to the frame, and at least one antenna electrically connected to the PCB via an antenna feed. The antenna may be shorter than a maximum specified length, and the antenna may be intended to operate within a specified frequency range for which the antenna's length is insufficiently long. Still further, in this system, electrical current flowing to the antenna may be routed to at least a portion of the frame to create a parasitic arm. As such, the parasitic arm may radiate in conjunction with the antenna, providing constructive interference in the specified frequency range. Various other mobile electronic devices, apparatuses, and methods of manufacturing are also disclosed.

Abstract: A disclosed computer-implemented method may include receiving, from a sensor included in an artificial reality system, data representative of an environment local to the artificial reality system. The disclosed method may also include determining, based on the received data representative of the environment, a probability that an environmental condition will impact a use of a plurality of antennas included in the artificial reality system by the artificial reality system. The disclosed method may also include adjusting, in response to the determined probability that the environmental condition will interfere with the use of the plurality of antennas, the use of the plurality of antennas by the artificial reality system. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: The disclosed system may include a support structure that may be configured to house electronic components. The system may also include a first antenna mounted to the support structure. The first antenna may be configured to provide a wireless intralink on a first frequency to a local mobile electronic device. The system may also include multiple second antennas that are configured to established wireless interlinks on other frequencies to various external wireless networks. The second antennas may be positioned a specified minimum distance away from the first antenna and may be positioned at an at least partially opposing angle to each other. As such, the second antennas may provide at least a minimum threshold amount of spherical radiation to transmit and receive data using the established wireless interlinks. Various other apparatuses, methods of manufacturing, and mobile electronic devices are also disclosed.

Abstract: The disclosed system may include an antenna and an antenna matching network. The antenna matching network may include an aperture tuner configured to shift a frequency response of the antenna and an impedance tuner configured to dynamically change an amount of radiated power for the antenna. The antenna matching network may be positioned at least a specified minimum distance from the antenna according to various operating characteristics of the antenna. Various other apparatuses, wearable electronic devices, and methods of manufacturing are also disclosed.
