https://devzone.nordicsemi.com/f/nordic-q-a/9930/nrf24l01-pcb-antenna-patternHello there, this is my very first post here. I have a pair of nRF24L01 modules with built-in PCB antenna, I would to know if is possible to obtain the approximated antenna gain and antenna patterns for this units, I&#39;m aware the radiation patternsen-USTelligent Community 13Thu, 17 Dec 2015 08:12:14 GMThttps://devzone.nordicsemi.com/thread/36839?ContentTypeID=1Thu, 17 Dec 2015 08:12:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6780e987-ca5b-4204-bc86-71f502d26cf3H&#229;kon Alseth<p>Hi,</p> <p>Attached is the plot of the nRF24L01+ module, mounted on top of the older evaluation kit that we had. As @Marco-Luis mentions; this is subject to change for each design, depending on the physical form, thickness of PCB, placement of components and external headers, placement of antenna on PCB, and many other factors.</p> <p>IE: This antenna radiation pattern will <em>not</em> be equal in other designs.</p> <p><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/Radiation_5F00_plots_5F00_nRF24L01_2D00_REFMOD.pdf">Click for radiation pattern.</a></p> <p>Cheers, Håkon</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/36838?ContentTypeID=1Thu, 17 Dec 2015 02:59:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bae86829-008b-4f99-a175-bd3464f010f1M.kodera<p>I want the PCB-Antenna gain data of EVM or simulation data. It is need to apply to TELEC Can we get the antenna measurement data?</p><div style="clear:both;"></div>
