Abstract: An electronic device may include a housing, processing circuitry carried by the housing, and at least one wireless transceiver carried by the housing and a NFC device carried by the housing. The electronic device may also include a display carried by the housing and having an internal surface within the housing and a display surface opposite the internal surface, and an NFC antenna mounted on and extending across at least a portion of the internal surface of the display, wherein the NFC antenna comprises a substrate and electrically conductive traces thereon defining a plurality of loops.

Abstract: A method and apparatus for controlling an antenna is provided. A load on a second antenna of a device is determined, the device comprising at least one processor, a first antenna, a variable tuning circuit connected to the first antenna, and the second antenna, wherein the processor determines the load. The processor controls the variable tuning circuit based on the load on the second antenna to change a match of the first antenna.

Abstract: An electronic device may include a housing having a display opening therein, processing circuitry within the housing, and wireless transceiver circuitry within the housing and coupled to the processing circuitry. The electronic device may also include NFC transceiver circuitry within the housing and coupled to the processing circuitry, a display within the housing and coupled to the processing circuitry, the display having an external surface exposed through the display opening and having an internal surface within the housing, and an NFC antenna positioned within the housing behind and aligned with the internal surface of the display and coupled to the NFC transceiver circuitry.

Abstract: A system and process that includes a multiband antenna as may be used in mobile communications devices. The multiband antenna includes a feed port coupled to each of a first radiating portion and a second radiating portion. Each of the first and second radiating portions defines a respective resonant bandwidth. The multiband antenna also includes at least one adjustable tuning circuit disposed between separate and displaced radiating segments of a respective one of the first and second radiating portions. Adjustment of the tuning circuit alters a corresponding resonant bandwidth allowing the corresponding resonant bandwidth to be tuned independently of the other resonant bandwidth and without affecting performance of the other resonant bandwidth. Other embodiments are disclosed.

Abstract: A system and process that incorporates teachings of the subject disclosure may include, for example, a multiband antenna as may be used in mobile communications devices. The multiband antenna includes a feed port coupled to each of a first radiating portion and a second radiating portion. Each of the first and second radiating portions defines a respective resonant bandwidth. The multiband antenna also includes at least one adjustable tuning circuit disposed between physically isolated radiating segments of a respective one of the first and second radiating portions. Adjustment of the tuning circuit alters a corresponding resonant bandwidth allowing the corresponding resonant bandwidth to be tuned independently of the other resonant bandwidth and without affecting performance of the other resonant bandwidth. In at least some embodiments, the tuning circuit can include a tunable phase shifter having one or more components, each having a variable reactance. Other embodiments are disclosed.
