I am looking for suppliers of RF modules and I hope you help me with choosing the right one. Specifically, I am interested in the RFID readers and appropriate antennas. I am working with a design that needs to follow the requirements listed below:
1) range between tag and antenna about 10-20cm
2) materials between tag and antenna:
~5cm wood plate,
~5-10cm polyurethane or polyester
3) possible some metal bolts in PU/PE
4) tag will have to be wristband
5) the antenna max size about A5 paper sheet
The position of tags may differ so perfect would be circular polarized antenna. The set will possibly work off-grid so would be nice to have something requiring less power. The tag will be connecting with very low frequency about 1 tag per 1-2 seconds.
I was hoping to find modules in low-frequency solutions. I am aware that distance of 10-20 cm may be a hard to get with LF/HF. I am also considering short-range UHF but the price of the module needs to be considered.
I would be grateful for your advice what module to choose.
Please let me know if there is anything else I need to clarify. I am looking forward to hearing from you.
