One-dimensional (1-D) slot resonator-based electromagnetic bandgap coplanar waveguide (SR-EBG-CPW) is proposed in this Letter. First, the SR-EBG-CPW unit cell is discussed and exhibits bandstop performance without any periodic structure. Then, its circuit model is extracted from the full-wave simulations and the frequency characteristics are explained by employing the equivalent circuit parameters and field analysis. Finally, a miniaturized bandstop filter with SR-EBG-CPW is presented and fabricated. Measurement shows that the designed filter provides good bandstop and slow-wave performances as predicted and has potential applications to compact microwave designs.
