RE: Reference PCB files for PCB Trace Antenna for NRF7002.

The 7002 works as both 2.4 GHz and 5 GHz.. so the once I mentioned is valid for the nRF7002 for 2.4 GHz.

Thank you for prompt reply. Do you have any idea about the PCB trace antenna for the NRF7002?

Hi,

we have this WP: "l/4 printed monopole antenna for 2.45GHz" you can have a look at, you are also free to copy our other pcb trace reference designs:

Monopole, printed PCB antenna: This is easy to make and easy to tune, you also only need one impedance matching component, so it’s cost effective. Here the spacing is the issues, you need to make it about 23 mm long needs a minimum of 5 mm clearance to the ground plane. High bandwidth, making it fairly resistant to detuning. See the white paper above or look at our nRF52 DK.

Meander antenna, printed PCB antenna, ex. our dongle antenna design: Requires a smaller area than the monopole antenna, but usually requires a pi-network for tuning in addition to length. Lower bandwidth than a quarter wave monopole antenna. Here is a link to our nRF52840 Dongle design files as an example of this: https://www.nordicsemi.com/Software-and-Tools/Development-Kits/nRF52840-Dongle/Download#infotabs

If you copy a printed pcb antenna, remember to add some extra mm of length for antenna tuning... and also copy the distance to ground.

We don't have a reference printed pcb antenna that works for both 2.4 GHz and 5 GHz.

Kaja
