The antenna is a simple trace though, some ~23mm long (add a couple of mm more if you want headroom for tuning it), you are better off just free-handing it. Further explanations can be found in <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.whitepapers/dita/whitepapers/pdflinks/nwp_008.html?cp=11_17">this whitepaper</a>.</p> <p>&nbsp;</p> <p>Also feel free to register a case if you want us to review it.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>
