您好Anastasiia，
它取决于您使用的协议和您正在设计的天线属性。
如果您使用适用于CR95HF阅读器的探索套件谈论接近14443协议，您可以达到4厘米。如果您使用相同套件的Viccinity 15693协议，您可以达到7厘米
但是这个套件再次是一个通用的多协议设置，可以专门修剪和调整。
我建议您使用ST25R3911 demonstartor板以获得更好的性能。
问候

Hello Anastasiia,
It depend on the protocol you are using and the antenna properties your are designing.
If you speak about proximity 14443 protocol with the Discovery kit for CR95HF Reader you can reach 4 cm.If you are in Viccinity 15693 protocol with the same kit you can reach up to 7 cm
But again this kit is a general purpose multi protocol setup and can be specifically trimmed and adapted.
I can suggest you for better performances to use a ST25R3911 demonstartor board.
Regards
