Dear Dilip, having a dedicated antenna is not an issue at all.Please have a look at AN5592.It explains how to do your own dedicated antenna. Same principle can be done with any commercial 50 Ohm NFC antenna.Our antenna matching tool helps you calcula...
Hello Samuel, achieving 1cm read range with 81mm x 47mm should be straight forward.Based on the available space you could place a ST25R3916B-STEVL like antenna in the free space and modify it to nicely fit.You can use the antenna tool in the ST e-Des...
Hello Mgscasso,Matching this antenna:Inside the datasheet you can find the antenna parameter in free air. If you don't have a VNA, this is a good starting point for you. There is no parallel resistance at resonance frequency state, but i think you ca...
Hello Ricko, There are no general or universal values you can input into the antenna matching tool.Those inputs are specific to your antenna. On a differently manufactured PCB, e.g. different layer stack, different dielectric parameter, the antennas ...
