I'm trying to design a PCB around the CLRC663 Plus IC for an university project.
I'm ok with anything power or digital related, but I don't have enough knowledge about RF so I cannot properly understand antenna design guidelines and similar.
My best shot is to use the awesome NXP NFC Antenna Tool (NFC - NXP Community).
Unfortunately, the tool seems to only support rectangular design antennas, but my project really requires a circular antenna with a diameter between 4 and 5 cm.
Any help adapting the input parameters (specifically the Length and Width ones) of the tool to support my use case and thus a circular antenna? If not, can you please provide me an already matched PCB circular antenna design with the required diameter (of about 5 cm)?
I know that I'm asking a lot and I really should study how to design and match a proper antenna but I don't have enough resources right now and without addressing the antenna part of the circuit the whole project cannot be done so I'm asking for your help, thank you!
