Part Number: RF430FRL152H

Hello

we are using the RF430RFL152H as a NFC battery free ADC

our first version was based on the evaluation board with 33mm diameter so we used the same antenna design

we are designing a new iteration of our design with 50mm outer diameter flex pcb ( i expecte the outer diameter of my antenna to be 46mm) since i need to keep 2mm gard on my flex)

please can you advice the best configuration for the antenna (number of round, track width and spacing)

looking forward for your feedback and support

best regards

Ziad
