| 摘 要： | 基于MF RC500的读写器的天线采用直接在PCB板上制作的微带天线,需要设计天线线圈,使其符合电磁传播规律.该电路要求使用无源的功率匹配网络将天线阻抗转为50Ω,然后由同轴电缆无辐射无损失的将功率从读写器传送给天线.匹配电路设计首先需测出天线的等效电路,再计算出天线的品质因子,然后得出匹配电路的电容值.

| Abstract: | The antenna of reader based on MF RC500 adopts striped antenna made from PCB, which must be complied with electromagnetism transmission law. In this circuit, it is required to convert the impedance of the antenna into 50? by passive power matched network, then the power will be transmitted from reader to antenna through the coaxial line without any loss. Firstly, the antenna's equivalent circuit and quality factor will be calculated, then the capacitance value of matching circuit can be worked out. |
