I am developing an RFID system that is capable to read a passive tag(M24LR04E) about 30cmMy antenna design chose Molex 1462360031 and the reader IC is ST25R3915. I use the matching circuit tool as the circuit reference but the signal did not pass ove...

After studying the datasheet of M24LR, I am not sure if I implement two 3v button batteries, the M24LR could send back some massage (like UID) to the reader with a stronger signal than other passive tags. Here are my questions: 1: Will the signal st...

I am doing a project which requires ST25R95 reading distance operating about 30cm. I studied the EV kit of ST25R95 and implemented the circuit as a reference to design my system.Unfortuneately, the reading distance is still around 7cm. After several ...
