https://devzone.nordicsemi.com/f/nordic-q-a/58401/how-critical-are-polygon-cutouts-under-component-pads-in-rf-nets-in-nrf9160-dk-designI understand the reason for the polygon cutouts under component pads in the RF nets in nRF9160 DK design (and others). However, at LTE and GPS frequencies this doesn&#39;t seem as necessary. I&#39;m curious, whether you (Nordic) do this as best practice or whetheren-USTelligent Community 13Tue, 03 Mar 2020 16:05:37 GMThttps://devzone.nordicsemi.com/thread/237854?ContentTypeID=1Tue, 03 Mar 2020 16:05:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7a1a1097-0593-4402-9f75-bc8bb07af399Felippe<p>Thank you!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/237503?ContentTypeID=1Mon, 02 Mar 2020 14:56:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d645e595-9e75-402f-8df3-196815613e90ketiljo<p>The cutouts under the component pads are there to reduce parasitic capacitance to ground. For single frequency antennas, like the GPS antenna and if the LTE modem is used on only one band, this is less important.</p> <p>If you plan to use several frequency bands, I&#39;d recommend to have the cutouts as it makes tuning the LTE antenna for a higher bandwidth somewhat easier. This can also be a case for certification as it&#39;s usually a requirement to have a&nbsp; minimum radiated output power.&nbsp;</p><div style="clear:both;"></div>
