Hi there,
I am trying to design and build a RFID system (tag and reader).
The requirements are the following:
1.The tag must be read by the reader up to a meter.
2.The tag tag should be small about=11mmx11mmx11mm)
3.The tag will be mounted on a metal
In my opinion I will use low frequency (125khz) because the skin effect will be lower and the signal will not be so affected by the metal. Also, I was thinking to use ferrite between the metal and the tag to increase the read range.
But I have a disadvantage by using low frequency. I cannot reach a meter.
The components that I was thinking to use are: tag:TK5551, reader: u2270b, and I was thinking to amplify the magnetic field by adding an amplifier if that would be possible. by using those components the max read range that I could achieve is 10cm without amplifier or something else.
If you have better ideas please help,any ideas would be acceptable and let me know how can I reach at least half meter by using a tag mounted on metal at what frequency and what tag and reader should I use please?
I NEED HELP URGENTLY PLEASEE.
