Abstract
A near field communication (NFC) system includes a plurality of coils for coupling to an antenna of a portable device, wherein each two adjacent coils are partly overlapped with one another; a multiplexer selectively enabling at least one of the coils to build a communication with the antenna, wherein the coils enabled by the multiplexer are selected to have a best coupling effect with the antenna and are combined into an effective antenna; and at least one adaptation network for adapting an input/output of the effective antenna.
