(a) Surface roughness of microstrip lines causes unpredictable losses in experiments. (b) Simulated results for S21 as a result of variation in substrate losses (tan δ) for double open-stub resonator. It is found that at a loss tangent of 0.0012 leads to an additional losses in the EIT band for the (c) the double stub and (d) triple stub cases.
