Transmission S21 characteristics for magnitude and phase of the (a,b) single, (c,d) double, and (e,f) triple open-stub resonator. Simulated results represented in the graph as solid line and experimental results as dashed line. Inset shows surface charge distribution at the resonance point identified as a point on the graph. The surface charge distribution are normalized for negative and positive values.
