https://devzone.nordicsemi.com/f/nordic-q-a/125641/antenna-designIs the schematics developed by our engineer for the antenna okay? 1. Is the L6 and 0 ohm resistors are for tuning? 2. Can I remove the 0 ohm resistor and use the same copper track instead of 0 ohm? regards viveken-USTelligent Community 13Wed, 19 Nov 2025 14:31:51 GMThttps://devzone.nordicsemi.com/thread/554813?ContentTypeID=1Wed, 19 Nov 2025 14:31:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:764d53ef-71bd-4f85-87ad-738d776212a9Bendik Heiskel<p>Hi Vivek,</p> <p>The schematic looks good.</p> [quote user=""]<p>1.

When the antenna is being tuned the 0 ohm resistor may need to be replaced with a inductor or capacitor in order to tune the antenna impedance to 50Ohm. Replacing L6 with a track removes the option to have a different component there when tuning reducing the options when tuning. Without L6 it may not be possible to tune the antenna to 50Ohm.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Bendik&nbsp;</p><div style="clear:both;"></div>
