Abstract
An anti-electromagnetic interference unit is provided, and the anti-electromagnetic interference unit is used to avoid that electromagnetic interference affects a NFC antenna module. The anti-electromagnetic interference unit comprises a plurality of EBG structures. Each EBG structure comprises a central body and at least one channel. The at least one channel is extended from the body, and extending shape of the at least one channel is a structure with a plurality of meanders.

An anti-electromagnetic interference unit connected to a NFC communication antenna module and used to avoid that the NFC communication antenna module is disturbed by electromagnetic wave, the anti-electromagnetic interference unit comprising:
- at least one electromagnetic band gap structure, each of the at least one electromagnetic band gap structure comprising:
- a central body;
- and
- at least one channel, wherein the at least one channel is extended from the central body, the at least one channel is configured on a remaining area which is defined as a coverage of the electromagnetic band gap structure subtracts a coverage of the central body, and an extending shape of each of the at least one channel is a winding structure with a plurality of meanders, wherein total length of each of the channels is determined through an inductance value corresponded to a needed inductance effect of the anti-electromagnetic interference unit.
