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： An antenna system for implementation in a wireless communication system such as a mobile device, and a wireless communication system employing such an antenna system, and a related methodology, are disclosed herein. In one example embodiment, a mobile device includes a display, a chassis, and one or more electrical components. The display is provided along a front surface of the mobile device, and the chassis has first and second cavities provided along a rear surface of the mobile device, the rear surface being substantially opposite the front surface. Further, the one or more electrical components is or are supported in between the display and the chassis, and the one or more electrical components provide excitation signals to one or both of the first and second cavities so as to cause electrical fields in accordance with a plurality of modes to occur respectively within the cavities at multiple frequencies, respectively.

摘要： The present invention provides a mid fed traveling wave antenna, which includes a signal feed point including a pair of terminals adapted for receiving a differential signal. The mid fed traveling wave antenna further includes a first transmission line branch extending from the signal feed point in a first direction, and a second transmission line branch extending from the signal feed point in a second direction, where each of the first transmission branch and the second transmission branch is terminated by a reflective termination. In at least one embodiment, the first transmission line branch and the second transmission line branch each have a respective length, where the length of the second transmission line branch is different than the length of the first transmission line branch.

摘要： Systems and methods for providing resonant wireless charging 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, GPS, and cellular drives respectively, while a wireless charging antenna sharing the same mechanical connections provides a differential drive across the antenna ends, forming a primary wireless charging coil. In an embodiment, a smaller multi-turn coil is connected to the primary wireless charging coil, and may overlay a device speaker and may also be shielded by a ferrite material. This structure or a dedicated similar structure on the device is then used for resonance-based wireless charging of the device.

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.
