Because when tuning the coil to 13,56 MHz and then connect the circuit to the IC the resonance frequency is totally different.</P><P>So its hard to tune the antenna to 13,56 MHz not knowing the input impedance of the ic.</P><P></P><P>Thanks</P><P>Josch</P></BODY></HTML> Tue, 08 Nov 2016 11:50:42 GMT https://community.nxp.com/t5/NFC/NT3H2211-Antenna-tuning/m-p/638516#M1455 josch 2016-11-08T11:50:42Z Re: NT3H2211 Antenna tuning https://community.nxp.com/t5/NFC/NT3H2211-Antenna-tuning/m-p/638517#M1456 <HTML><HEAD></HEAD><BODY><P>Hello <A _jive_internal="true" data-userid="290298" data-username="josch" href="https://community.nxp.com/people/josch">Jochen</A>,</P><P>&nbsp;&nbsp;&nbsp; please register your account and download corresponding documents! the document is AN11276.zip, it's link is :</P><P><A class="link-titled" href="http://www.nxp.com/confidential/AN11276?fsrch=1&amp;sr=1&amp;pageNum=1" title="http://www.nxp.com/confidential/AN11276?fsrch=1&amp;sr=1&amp;pageNum=1">NXP Semiconductors :: Secure Connections for a Smarter World</A>&nbsp;</P><P><span class="lia-inline-image-display-wrapper" image-alt="pastedImage_2.png"><img src="https://community.nxp.com/t5/image/serverpage/image-id/7493i379406A15E23F01F/image-size/large?v=v2&amp;px=999" role="button" title="pastedImage_2.png" alt="pastedImage_2.png" /></span></P><P>Best Regards,</P><P>Weidong</P></BODY></HTML> Wed, 09 Nov 2016 08:13:25 GMT https://community.nxp.com/t5/NFC/NT3H2211-Antenna-tuning/m-p/638517#M1456 weidong_sun 2016-11-09T08:13:25Z
