https://devzone.nordicsemi.com/f/nordic-q-a/30569/clarification-on-pcb-antenna-designHi, i am evaluating the use of the nRF51822-QFxx for our product and made good experience with the nRF51-DK. Now, i would like to layout the custom pcb and i am not sure how to design the antenna. Due to space issues, i would like to use a meandereden-USTelligent Community 13Fri, 16 Feb 2018 11:52:58 GMThttps://devzone.nordicsemi.com/thread/121070?ContentTypeID=1Fri, 16 Feb 2018 11:52:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:47c1fc84-9cc7-45b4-ab83-41e6f4a5058aketiljo<p>I&#39;ve tried exporting from Altium before without luck. CAD software are generally better importing than exporting formats. It&#39;s probably faster just to recreate the antenna&nbsp;using the dimensions.&nbsp;</p> <p>Ketil</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/121067?ContentTypeID=1Fri, 16 Feb 2018 11:17:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3539bf45-b95d-472c-a5bd-bf8314934886DanKA<p>Hello and thank you for your reply.
