BC660K-GL-TE-B (BC660 dev kit) Antenna model / part-no included

Hello,
I just received my BC660 dev kit.

The antenna included in the kit has no marking on it,
does anyone knows the part number of it?
(a data sheet of this antenna would be even better)

Thanks

Replying to myself, just to be useful for anyone at the future.
