https://devzone.nordicsemi.com/f/nordic-q-a/43002/nfcBased on nrf52832 development nrf as a tag, the actual distance is 2 cm, less than 3 cm with a reader, how to improve for it? Let the distance of nfc exceed 3 cm?en-USTelligent Community 13Sat, 26 Jan 2019 02:32:04 GMThttps://devzone.nordicsemi.com/thread/168050?ContentTypeID=1Sat, 26 Jan 2019 02:32:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9208800f-5473-48c3-b007-ef3484ce2239alan11<p>ok，Let me try ，Thank you</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/167910?ContentTypeID=1Fri, 25 Jan 2019 12:46:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4708eac9-3cf5-4757-8713-0a2113cd787bAndreas<p>Hi,</p> <p>&nbsp;</p> <p>You need to make sure the size and shape of the tag antenna and the reader antenna is as similar as possible to maximize the field coupling. In addition the antennas should not be enclosed by metal planes. Also you need to make sure that both antennas are tuned, see <a href="https://www.nordicsemi.com/DocLib/Content/White_Papers/nwp_026/latest/WP/nwp_026/nWP_026_intro">this application note</a>. Achieving 3cm is typically possible, but exceeding 3cm might not be as easy.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>
