Abstract
Various configurations and arrangements of various communication devices and antenna solutions are disclosed. Antenna solutions disclosed herein include a near field communication (NFC) controller, and at least one antenna interface circuit, which together may control and effectuate NFC communications via at least two NFC antennas. The at least two NFC antennas may be connected together in series or in parallel, and may be magnetically isolated by an isolation element.
Claims20
An antenna arrangement for facilitating near field communication (NFC) in an NFC enabled communication device, comprising:
- at least two antennas connected either in series or in parallel;
- at least one antenna interface circuit;
- an NFC controller operably connected to the at least one antenna interface and configured to control operation of the at least two antennas;
- and
- an isolation element adapted to magnetically isolate the at least two antennas from each other.
A device, comprising:
- a first near field communication (NFC) antenna located in a frontal region of the device;
- a second NFC antenna located in a rear region of the device, the first and second NFC antennas being connected in series, and being magnetically isolated by an isolation element;
- an antenna interface circuit;
- and
- an NFC controller adapted to, with the antenna interface circuit, control and drive the first and second NFC antennas to effectuate NFC communications.
