摘要： Embodiments include an antenna assembly comprising a non-conductive housing having an open end; an antenna element positioned inside the non-conductive housing; an electrical cable having a first end electrically coupled to the antenna element and a second end extending out from the open end; one or more dielectric materials positioned inside the non-conductive housing; and a conductive gasket coupled to a portion of the electrical cable positioned adjacent to the open end and outside the non-conductive housing. One embodiment includes a portable wireless bodypack device comprising a frame having a first external sidewall opposite a second external sidewall; a first antenna housing forming a portion of the first sidewall and including a first diversity antenna; and a second antenna housing forming a portion of the second sidewall and including a second diversity antenna. Embodiments also include a method of manufacturing an antenna assembly for a portable wireless bodypack device.

摘要： Systems, apparatuses, and methods are described for increasing detune-resiliency of a user device during user-interactions. An antenna bandwidth may be increased, via modification of one or more antenna characteristics and/or the addition of one or more novel antenna components, in order to increase the detune-resiliency of the antenna. Moreover, user interface elements of the user device may be located outside of a protected region of the antenna. Thus, the user device may be more resilient to detuning during user interactions.

摘要： Adaptive self-tunable antenna systems and methods are provided including a closed-loop system for sensing near-field RF signals of transmitted RF signals and tuning an antenna or switching between multiple antennas, so that the strength of the transmitted RF signals is maximized. A sensing antenna detects the near-field RF signal, which is filtered and converted to an RF strength control signal that can be used to generate an antenna tuning control signal. An antenna tuner uses the antenna tuning control signal to keep the antenna in resonance by dynamically changing the electrical length of the antenna or switching between multiple antennas to maximize the strength of the radiated RF signal. Such antennas may be less prone to detuning due to interaction with human bodies or other objects. Dynamically matching the antennas to an RF power amplifier and low noise amplifier can improve stability, power efficiency, gain, noise figure, and receiver sensitivity.

摘要： A wearable device, such as an earphone, may include a conformal antenna that is resilient to performance degradation due to user-interactions and manufacturing process variances. The antenna may comprise one or more surfaces suitable for receiving and transmitting electromagnetic signals, wherein the one or more surfaces of the antenna may be non-parallel with a ground plane and a user-interactable surface, thereby minimizing image current cancellation and coupling between the antenna and a user finger during user interactions with the user-interactable surface.
