Microstrip Filling Factor versus Relative Dielectric Constant Given fixed Line Impedance

Research Links Microwaves101: Filling Factor The question arose given a fixed microstrip transmission line characteristic impedance how does the percentage of the field in the substrate change? This is called the filling factor: Keff=ER*FF+1x(1-FF) It is the fraction of the field in the substrate.  I calculated the following values: FF=(Keff-1)/(ER-1) Dk=4 Read more…
