Hello I am trying to create a PCB trace line from a GPS receiver to a GPS patch antenna. This antenna operates at 1.5GHz and needs a 50 ohm impedance line. I was told that copper at 1Ghz has a Dielectric Constant of roughly 3.5. using http://www.pcb123.com/help/calculators/microstrip.html and e…

PCB trace 50 ohm impedence
