Hi Giovanni, Any antenna that support 2.4GHz and 50Ohm impedance should work. I would suggest to follow the antenna made for the nRF51 development kits for your design.

You can also have a look at this document for monopole antenna design. Also please don't forget to add the tuning component to tune the antenna. Please have a look at this document.
