Embodiment Construction

[0032] Aspects of the present invention are believed to be applicable to various types of devices, systems and methods involving antennas. In certain embodiments, aspects of the invention have been shown in dual-mode antennas (e.g., dual-mode antennas implemented to communicate (transmit and / or receive) signals at different frequencies and / or for different purposes) Beneficial when used in certain situations. In some embodiments, these aspects relate to circuitry that couples a radio frequency (RF) signal to a wireless power / charging circuit and communicates the NFC signal to the NFC circuit while reducing coupling of the NFC signal to the wireless power / charging circuit. Such circuitry could, for example, be implemented in a portable device that utilizes wireless charging for storing energy in the battery and also utilizes NFC (or other RF) communication. These and other aspects can be implemented to address challenges including those discussed above. While not necessarily ...

Abstract

Aspects of the present invention relate to an antenna, various embodiments and methods thereof. Various embodiments are suitable for implementation with receiver circuits and near field communication (NFC) circuits that use energy from received radio frequency (RF) signals to harvest power. A first antenna collects and presents RF signals to the receiver circuit, and a second antenna communicates NFC signals for the NFC circuit using the antenna portion shared with the first antenna.

Description

technical field [0001] Aspects of the invention relate to apparatuses, apparatuses and methods for antennas and implementations thereof. Various aspects relate to antenna circuits providing different reception characteristics, portions of which may be referred to as dual-mode antennas. These reception characteristics can be used in various applications. One such application involves wireless charging and wireless communication. For example, in various embodiments, wireless charging circuitry is implemented using one or more common antenna windings along with near field communication (NFC) circuitry. Such embodiments may be suitable for implementation with, for example, portable devices such as mobile phones or the like. Background technique [0002] Wireless charging embodiments may relate, for example, to charging methods set by the Wireless Alliance (A4WP). The approach of using A4WP may allow for larger, more powerful designs and may be more practical as it charges mu...
