A new compact microstrip dual-mode bandpass filter with the center frequency of 2.4GHz is proposed based on embedded capacitance material (BaTiO3-epoxy composite film). The filter consists of a defect ground structure (DGS) and an open-loop step-impedance resonator with a short-circuit line in the middle of the resonator. The bandwidth of the filter can be optimized by adjusting the width of the short-circuit...
