I means RFID products like MicroChip, Atmel, HiTag. But all of above use 13.56MHz .

Sorry for my misunderstanding! The RFID you can looking for is major for near field coupling (magnetic compoent majority), it is usual loop antenna like smart card.

Try to download Smart Card Manufacturing from forum, you will get more idea.
