Antenna for small ISO14443B tag

Hi guys, I have this tag sub-model explained at page10 [AT88RF04C]; the tag is 1x1 cm and it is not seen by my proxmark antenna... my doubt is: can the tag "smallnes" create problems with a "big" pm3 antenna causing it not to be read ? I tested every possible position...

I try to reply at your question. For small RFID I created a small antenna 2 cm diameter and 6 turns. The wire enamelled is about 1 mm diameter. I maked many tests before to reach a good voltage with hw tune about 11V. I can ensure it's work with a little tag SRIX4K.
