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

Hi Lyadnov,

Hi Lyadnov,

I would suggest you to read AN-B-027: Designing Printed Antennas for Bluetooth Smart from 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

Hi Lyadnov,

Hi Lyadnov,

I will ask our support team to look into it to see if they have guidelines for alternative PCB thickness.

Hi,

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.

The matching network as to be checked always, when putting the antenna into a housing. While doing this, the thicker substrate can be taken into account as well.
