摘要： A communication device includes a processor subsystem that is in communication with a communication module, which is communicatively coupled to an antenna array to transmit and receive signals. The processor subsystem executes a near-field detection application to perform a method including transmitting, via the antenna array, a signal that is swept across a range of frequencies and receiving any back-scattered signals in the range of frequencies. The method includes determining whether a near-field obstruction exists based on characteristics of the received back-scattered signals. In response to determining that a near-field obstruction exists, the method includes triggering the processor subsystem to perform one or more responsive operations on the communication device. The operations include a selected one of: (i) altering a transmission beam transmitted by the communication device; and (ii) triggering an application to execute on the communication device, the application intended to interact with a user of the communication device.

摘要： Systems and methods for providing NFC (near field communications) in a portable communications device utilize antenna arms formed from openings in a metal unibody construction. Two of the antenna arms are driven by WiFi and cellular drives respectively, while an NFC antenna drive sharing the same mechanical connections provides a differential drive across the antenna ends, forming a primary NFC coil. In an embodiment, a smaller multi-turn coil is connected to the primary NFC coil, and may overlay a device speaker and may also be shielded by a ferrite material.

摘要： A wireless charging apparatus can include an exciter that initiates and shapes electromagnetic fields of microwave frequency. The exciter can include a ground structure and a feed structure disposed within the ground structure. The wireless charging apparatus can also include an adapter configured to hold a device to be charged with a side of the device to be charged exposed external to the apparatus while charging the device to be charged. The adapter can transmit the microwave power from the exciter to the device to be charged.
