Other Parts Discussed in Thread: MRD2EVM
Hi,
I have been working with S2000 (Low Frequency) RFID readers in several applications. One of the limitations is no multitag reading. However, why are no transponders developed with several coils oriented perpendicularly?
Since the 'readout diagram' of the transponder depends on the orientation of the transponder with respect to the reader antenna. I would like to know/build a transponder with several coils to avoid this orientation dependency. I know I could use differente configurations for the antenna readers, but that is not a possible solution for me.
I am somehow surprised that there are no transponder built with this feature . I put as example the transponder https://www.ti.com/product/RI-TRP-DR2B .
I have the following questions:
1- Is there anything I am missing or reason why tags with differents antennas are not developed?
2- Given the fact it seems TI does not manufacture 134 kHz transponders with several antennas embedded, is there any manufacturer or any starting point to build it on my own?
Regards,
