PCB Dielectric Constant and comparative dielectric FR4 permittivity are a statistic software developers frequently utilize, sometimes without knowing it completely. Each substance has a dielectric constant, possibly a little more than equality air. The character is usually used to evaluate multiple circuit...

You can look up the specs of the material at the PCB producer. The dielectric constant doesn't depend on the frequency but the loss in the material does. If the application has to be very precise go for Rogers material otherwise FR4 is good until several GHz (assume er=4.5). When worki...
