Need reference or help to design nRF54L15 BLE antenna using chip antenna

[GokulPrasanth]

Hi everyone—I'm working with the Nordic nRF54L15 SoC, but I'm struggling to find guidance on using a chip antenna (design and components). The official materials (e.g., DK designs and reference layouts) mainly demonstrate PCB trace antennas or tag-style "RF" options—not chip antenna implementations—which is what I need for my compact product.

Could anyone share experience or design guidance for:

1. Selecting appropriate chip antenna models (for BLE/Thread and Wi‑Fi coexistence).

2. How to handle antenna matching networks specific to chip antennas when used with nRF54L15.

3. Any layout recommendations, including grounding, clearance, or placement—especially in constrained spaces or challenging enclosures.

4. Examples from Thingy, DK, or modules that already use chip antennas as reference.

I'm not an RF specialist, so any step-by-step help—component values, placement rules, or antenna vendor suggestions—would be hugely appreciated. Thank you in advance!

Most, if not all, chip antennas have very specific designs, where the layout is a critical part of the design. Refer to the datasheet of the antenna and make sure you copy the design exactly as shown. Some antennas have specific placement requirements, like edge or corned mounting. Do not use the antenna in another position. 

All chip antennas needs tuning with external components. You would normally have a pi- or T-filter between the antenna and the radio's matching network. See https://docs.nordicsemi.com/bundle/nwp_017/resource/nwp_017.pdf
