摘要:
Described herein are techniques related to near field communication and wireless power transfers. A portable device may include a modular antenna that offers consistent characteristics independent of integration environment. The modular antenna may include a continuous loop of coil antenna and a ferrite material that are encapsulated by a shield. The shield may form a “U” shape configuration to encapsulate the top layer coil antenna and the middle layer ferrite material in all three sides, which are defined by a bottom portion, an outer wall, and an inner wall. Furthermore, the shield may include an outer rim and an inner rim to maintain the same coil antenna characteristics in the modular antenna.

Described herein are techniques related to near field coupling and wireless power transfers. For example, a coil antenna configuration is the same in all portable devices; however, when the portable devices are arranged in back to back position with one another, the coil antenna configuration defines a dissymmetric and antenna configuration.

Described herein are techniques related to near field coupling and wireless power transfers. A portable device may include a coil antenna that includes an upper loop and a lower loop to form a figure-eight arrangement. The figure-eight coil antenna arrangement is wrapped against top and bottom surfaces of a component to establish near field coupling through front side, top side, bottom side, or corner side of the portable device. Further, a flux guide may be placed between the coil antenna and the component to facilitate magnetic flux at the upper loop and the lower loop to induce current of the same phase during receive mode. During transmit mode, the flux guide facilitates the magnetic flux at the upper loop and the lower loop to generate magnetic fields of the same direction.

Embodiments of a system and method of determining total isotropic sensitivity (TIS) of a wireless broadband client device are described herein. A received signal strength indicator (RSSI) reported at an embedded radio module of the device is logged for each of a plurality of antenna polarizations and for each of a plurality of platform orientations. A single point measurement of module sensitivity is performed at a reference orientation and polarization the transmit antenna. The TIS is calculated as a correction to the single point measurement of module sensitivity. A correction factor to correct the TIS may be based on the difference between an average of the logged RSSIs and an RSSI at the reference orientation and polarization of the transmit antenna.
