Hello to everybody, I would like to ask you for help me find the simplest way to calculate matching circuit for class 6 antena from your reference design (hope that I understood it right that is possible to use class 6 design for this part number). Im not really the expert for anthenna design and not to much time for learn and understand formulas and simulation SW. Before we use NTAG I2C primary function is data transfer between RF and I2C, but our customer newly wants to create battery less device, so we need high current output than NTAG was able to delivery, so this is reason why we chose from NXP NTP53321 IC with higher current output. before I used generic antenna design with 50pF C and works fine, now I readed that is newly need matching circuit. I prefere to use class 6 becase is still fit my free space on board for anthenna 31x21mm space with IC in middle of side. Any body to help me implement it?
Thank you very much in advance.
BR,
Jaromir
