ICODE SLIX2 Reading Hole

[naokiokazaki]

Hi, Team

Could someone help me the reason why I had a trouble of reading hole with ICODE SLIX2?

We have developed a new Tag with ICODE SLIX2 which showed better read range compared to ICODE SLI.

However, I saw an issue of the reading hole (null point) at the distance close to a reader antenna and as moving

it away from the reader antenna, it is no problem, we can get UID perfectly .

I did not see such a symptom with ICODE SLI.

Best regards,

NA

Hi NA,

This should be a antenna design issue, please kindly check the antenna design on ICODE SLIX2 side, especially the antenna matching. Please refer to the following link for more details.

Kan

Hi! Kan

Thank you for your input.

However, this is th case of HF, not UHF which you showed here.

I am afraid that the event is different between two.

Best regards,
