I need to match the impedance (50ohm) of an active GPS antenna, from the
connector on the board. How can I calculate the size and width of the strip
to match? Is there any way to do this on Eagle ?

This link work http://www.eecircle.com/applets/015/Gcpw.html
or you can use Width=1.75 PCB heigth.
I have use this for GPS design but allways with RF, shortess is best.

Hi Thiago,
Look ULP length-freq-ri.ulp, it's perhaps ok for you.

There is good free sw caled AppCAD from Aglient technologies.
Try this and you'll be satisfied.

The name of the company is Agilent not Aglient as I wrote . Here is example of the microstrip calculation:
