Mifare天线设计怎么天线的电感值

你好Ufuk，
我们使用RF模拟软件确认设计1和2的理论值。根据我们的经验，我们相信天线的电感测量应该非常接近。
模拟和原型之间差异的两种可能的解释是，第一次是环路匝之间的短路，第二是PCB上天线的实施问题：如果由于某种原因某些铜区域覆盖环形天线，磁通量会被阻塞测得的电感远低于预期。
如果您打算使用ST产品（Mifare不是STMicroelectronics产品品牌），我们可以进一步分析您的PCB布局。
最好的祝福，

Hello Ufuk,
we do confirm the theoretical values for design 1 and 2 using an RF simulation software. Based on our experience, we are confident that antenna a inductance measurements should be very close.
Two possible explanation of a difference between simulation and prototype are, first short cuts between turns of the loops, second an implemantation issue of the antenna on the PCB: if for any reason some area of copper covers the loop antenna, magnetic flux is blocked resulting in a measured inductance much lower than expected.
If you are planning to use an ST product (Mifare is not an STMicroelectronics product brand), we could go further into the analysis of your pcb layout.
best regards,

谢谢你的解释。我想改进现有的天线。 pcb是天线在同一区域。我还使用M24LRE设计了另一台pcb。我订购了样品，我会试试。

Thank you for yours explanation. I want to improve the current antenna. Antennas are in the same region both pcb's. Also I've designed another pcb using M24LRE. I ordered the sample and I will try it.
