摘要： This paper introduces a method of impedance matching for 13.56 MHz NFC antennas without Vector Network Analyzer (VNA). A LCR meter is used to measure resistance and inductance of antennas instead. A three components match is adopted to realize 50-Omega antenna impedance. Both antenna on board and external antenna are designed with rectangular planar spiral copper. They are tested and compared with each other. The results show that two antennas can work well. External antenna has better performance than one on board.
