I have to calculate the Transmission line Trace width for 50 ohm FR4 6 layer PCB. so i want to know that it is called micro-strip or strip-line?
i have check the calculators like Chemandy's , APPCAD. But confused between for what transmission line i have to calculate.

1) RF signal contains in 1st layer so which calculator used? co planner or Micro strip?
2) How RF Trace length important? any calculator for RF length calculation?
