Hi,

Length of the rack is not important as long as it is impedance matched.

[quote user=""]if i decrease this length, how i can set antenna parameters?[/quote]

No problem reducing the length.

[quote user=""]another question: what is the R1 =0 ohm resistor and N.C capacitors ? why we put it?[/quote]

the N.C component is there just in case some extra tuning components are needed. It can be removed from most designes if the matching is sufficient.

Some extra info here:https://devzone.nordicsemi.com/guides/hardware-design-test-and-measuring/b/nrf5x/posts/general-pcb-design-guidelines-for-nrf52-series

Also here is a video with one of our engineers taking about PCB design: PCB Antenna - How To Design, Measure And Tune

If you are making a design with nordic components feel free to ask for a review and we will provide feedback on the design.
Just create a new ticket and call it HW review and add the schematic and layout files, in PDF, Altium, GERBER and we will have a look.

Regards,
Jonathan
