https://devzone.nordicsemi.com/f/nordic-q-a/112233/nrf52832-antenna-matchingGood Afternoon, I&#39;m designing a 4-layer PCB based on an NRF52832 (QFAA) paired wit h a Molex 479480001 SMT Antenna, and I was hoping for some feedback on Antenna Matching. Here&#39;s a partial screenshot of the current layout, followed by the associateden-USTelligent Community 13Wed, 19 Jun 2024 13:21:32 GMThttps://devzone.nordicsemi.com/thread/489536?ContentTypeID=1Wed, 19 Jun 2024 13:21:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e5085c3e-5f3e-48e4-b395-b68abc94e84bJONATHAN LL<p>Hi,<br /><br />We have some extra info&nbsp;here:&nbsp;<br /><a href="https://devzone.nordicsemi.com/guides/hardware-design-test-and-measuring/b/nrf5x/posts/general-pcb-design-guidelines-for-nrf52-series">https://devzone.nordicsemi.com/guides/hardware-design-test-and-measuring/b/nrf5x/posts/general-pcb-design-guidelines-for-nrf52-series</a>&nbsp;<br /><br />But mostly ok, just follow the layout recommendation for best results.&nbsp;<br /><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/3617.pastedimage1718803182365v1.png" alt=" " /><br />C8 should only be connected to pin and inner GND center pad, so you can disconnect it from the top GND layer(black X), reason for this is due to filtering of harmonics.&nbsp;<br /><br />Like this:<br /><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1718803323658v1.png" alt=" " /><br /><br /><br />Regards,<br />Jonathan</p><div style="clear:both;"></div>
