Hi, I’m working on a small board design using the GR-10 GPS receiver and the GPS chipscale antenna. In the datasheet for the antenna it mentions a 50ohm microstrip, I’m only vaguely familiar with microstrip traces - I understand the idea is to have a controlled-impedance trace, and I used a free onl…

50ohm microstrip in GPS chipscale antenna datasheet, help!!

Touche…based off this calculator http://divsys.com/Tools/CICalculator/Microstrip.asp a .128" trace will work for an impedance of 50 ohms and FR4 standards.
