Hi, I recently took this nRF24L01 smd version and I make my own PCB using EAGLE
but I can't find anywhere the smd pins to use them and solder the nRF directly on my PCB.
Any help will be nice.
You can download the exact image / smd nRF I will use

You'll have to make one up in Eagle as that looks like a custom module you are adding to a PCB.
Follow the steps here. Should not be hard as the board outline is pretty straightforward and the pads regularly spaced it appears.
Hmm that's really useful, never made a custom component, I will give a try later and post my results.
Thanks.

I struggled making them initially, as I was doing it so infrequently I couldn't remember what I had done the previous time.
Now I've done enough it's not a problem.
You may need to get some calipers to make more mechanical measurements, the drawing you posted doesn't have much to go on as far as pin spacing and where other holes are for mounting the board.
Make sure your antenna is not over a ground plane on your PCB, or that it hangs off the side of your PCB when installed.

There will be a problem if I but the antenna above a ground surface?
Yes. Read nrf2401+ documents for recommendations on laying out a PCB antenna - no ground plane under the strip. Having ground plane under the strip antenna on the module would be a similar thing to avoid. Being over more PCB may also affect the impedance of the antenna and impact antenna performance.
Try using 'sonnet' - you can get a restricted version free - to model the antenna.
A ground plane is definitely OUT!
