Hi all,
I am working on a RFID project. The requirement is to send a "27MHz" telepowering signal from the READER to the TAG, this is just a carrier wave to power up the tag and contains no data. Backscattering technique cannot be used here since the data that is sent back from the TAG should be at a frequency of 3.951MHz for logic'0' and 4.516MHz for logic'1' i.e: FSK technique is to be used rather than the conventional ASK. This requires two seperate antennas for both READER and TAG. The Tx antenna from the TAG and Rx antanna of the READER are centre tuned to a frequency of 4.234Mhz (This i hope everone can make out how).
The Design of both the reader and the tag is to be done for this setup. The mechanical size of the tag is not a big consideration.
Can anyone please guide me in this regard?
