Dear support team. Could you please, tell me about matching for IFA, if PCB have 1,6mm thick.

Hi Lyadnov,
I would suggest you to readAN-B-027: Designing Printed Antennas for Bluetooth Smartfrom our support website. You will find the correct guidelines for designing printed antennas. You could also download the DXF files from this link :AN-B-027: Designing Printed Antennas: DXF files.
Thanks, PM_Dialog
Dear, i have read AN-B-027 and make design according it, but in this document used 1mm thickness PCB for matching IFA
Hi Lyadnov,
I will ask our support team to look into it to see if they have guidelines for alternative PCB thickness.

Hi,
Our RF team replied as follows:
I would suggest not to change the antenna traces, but to adapt the matching components. A substrate change to 1.6mm will introduce only a small detuning to the existing antenna structure, that can be tuned by changing the matching network.
检查alwa匹配网络ys, when putting the antenna into a housing. While doing this, the thicker substrate can be taken into account as well.
