摘要：

For stable wireless charging and reliable data communications in mobile devices, the proposed high-isolation dual antenna operates at two different frequency bands such as 6.78 MHz at wireless charging and 13.56 MHz at near-field communication (NFC). To increase the isolation between antennas, the proposed dual antenna has an antiparallel coil structure. It has achieved approximately more than 20 dB isolation between antenna ports.
