Antenna for 14443 type B tags (srix4k)
Hi,
I need to build an antenna for srix4k, can help me?
do I have to 
but reading is very poor, and often fails. Anyone have information to create my own antenna for better results?
thanks.

Jonor you are right, that small antenna works GREAT with small tags! Thank you man !!!
thanks.
I created my antenna with 6 laps and Cable 1.2mm . The voltage is too low ... but I read more or less well (25 % of the time correct reading ) .
As I can improve it ?
