We have a white paper available on this type of antenna:</p> <p><a href="https://infocenter.nordicsemi.com/pdf/nwp_008.pdf?cp=17_18">https://infocenter.nordicsemi.com/pdf/nwp_008.pdf?cp=17_18</a></p> <p>The hardware design files for the nRF52840DK is also available for download:</p> <p><a href="https://www.nordicsemi.com/-/media/Software-and-other-downloads/Dev-Kits/nRF52840-DK/nRF52840-Development-Kit---Hardware-files-2_0_2.zip">https://www.nordicsemi.com/-/media/Software-and-other-downloads/Dev-Kits/nRF52840-DK/nRF52840-Development-Kit---Hardware-files-2_0_2.zip</a></p> <p></p> <p>Best regards,</p> <p>Bendik</p><div style="clear:both;"></div>
