Hello

Any antenna that's designed for 2.4 GHz can be used with nRF52 devices. For very small devices, you should look for a ceramic chip antenna. There are numerous types to choose from. 

In any case, it's vital that the antenna's recommended placement and layout is followed. This is normally shown in the antenna datasheet or app.note.
