But they are normal 1/4 wavelength monopole antennas and the gain&nbsp;is&nbsp;&nbsp;~ 0 dBi. We have this white paper that you could refer:&nbsp;<a href="https://docs.nordicsemi.com/bundle/WP_PDF/resource/nwp_008.pdf">https://docs.nordicsemi.com/bundle/WP_PDF/resource/nwp_008.pdf</a>&nbsp;</span></span></p> <p><span><span dir="ltr">Best Regards,</span></span></p> <p><span><span dir="ltr">Swathy</span></span></p><div style="clear:both;"></div>
