https://devzone.nordicsemi.com/f/nordic-q-a/22369/pcb-antennaHello, I want to design PCB antenna for nRF52832 chip. I took reference from nRF51 dongle hardware layout. I wanted to spread antenna upto 18mm width so I reduced the height of antenna increasing the width of it, but the overall length of antennaen-USTelligent Community 13Tue, 30 May 2017 07:56:01 GMThttps://devzone.nordicsemi.com/thread/87928?ContentTypeID=1Tue, 30 May 2017 07:56:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1841bd60-b318-4171-b70f-0adf8b08f118Swapnil<p>Thank you for your answer, that really helps. I will try to integrate the antenna from nRF-51 dongle.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/87927?ContentTypeID=1Mon, 29 May 2017 07:29:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7182a535-27eb-414b-a771-779c51bcf04bFormerMember<p>A monopole antenna radiates from the sides of the antenna. A meander antenna, like the antenna on the nRF51-dongle, radiates from the corners. To avoid interference problems, meander antennas are therefore quite complicate to design. And we recommend to copy the one on the nRF51-dongle, because we know it works well. If changing the layout of the antenna, we don&#39;t know how it will perform.</p> <p>Since the width of your PCB is 18 mm, a monopole antenna can be an option in your case. Typically, the length of a monopole antenna is 22 mm, measured from the last tuning component. <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.whitepapers%2Fdita%2Fwhitepapers%2Fpdflinks%2Fnwp_008.html&amp;cp=11_14">This</a> whitepaper describes how to design a monopole atnenna.</p><div style="clear:both;"></div>
