Hi,
you will need so-called far field tags to achieve a read range of 5m.
These tags have usually a kind of loop in combination with a dipole.
Here is a typical design example:
The ST25RU3993 EVAL board demo kit includes two of such tags.
Another important point is to have a far field reader antenna as well.
The ST25RU3993 EVAL board demo kit does not include such a far field antenna!
It just includes a near-field antenna (max. read range: 0.3m).
So if you buy a ST25RU3993 EVAL board, you have to buy a far field reader antenna separately in order to achieve 5m read range.
Best regards,
Marcel
