nRF52832 antenna files

I am using Meander line inverted F antenna for beacon and development board based on nRF52832.

Is it okay to go with this antenna or shall i change this antenna.?

Where can i get the dxf files of antenna used in Nordic dev kits.?

  • Hi,

     

    The antenna design is fine, but I have some other comments to your design:

    • You need more vias across the ground planes and in the center pad of the nRF.
    • The part underneath (in the bottom layer) the RF components must be solid ground
    • C10 shall only be grounded into the center pad through pin 31, like in our reference layout:

      Also note the keepout around L1 (L3 in your design)
    • Add/extend a ground pour here with a couple vias:
    • You need to add two more components for tuning the antenna, a series component and another shunt component between C11 and the antenna (making a pi filter along with C11).

     

    Best regards,
