Hello Everyone...
I have made antenna and tuning network which can detect MiFare and HiD iClass cards. i.e. 13.56Mhz... So for that i need to control unwanted harmonics of 13.56Mhz... I have designed antenna tuning circuit as per MiFare suggest. Card detection range in around 4 cm. So how can I reduce effect of harmonics???
And what is the significance of the series register which is connected to antenna which is referenced as Rq. and having range on 1Ohm to 3.3Ohm limit???
Do we can nullify the harmonics by reducing range of antenna???
