Hi, Sorry if someone have already made this question but I couldn’t find anything similar.
I’m very new at this EAGLE thing and I’m trying to make a footprint for a bluetooth (MDBT40-P-256RV3) and I have to draw an antenna but I don’t know how to create it on eagle. Also,I didnt find any measure on the datasheet for the antenna and I have to deliver a project tomorrow. Everything else is done but the antenna 
can anybody help me please?
Thanks! 
If the antenna doesn’t have to work well, any trace open on one end will do. No ground plane under it, of course.

Antenna design is more art than science.
Better yet, just attach 1/4 wavelength * 0.7 in length of wire to the board. It’ll work better.
There is an interesting resource by TI regarding antennas:

Just make sure you choose the 2.4GHz ones. Are you intending to include a matching network for the antenna as well?
