摘要

In this paper a compact novel dual-band bandpass filter (DB-BPF) with independently controllable frequencies and bandwidths is presented and the procedure of its design is discussed. The proposed filter consists of an open-loop dumbbell shaped (OLDS) defected ground structure (DGS) and step impedance cross-shaped lines (SICSLs). To generate the first band, the authors used a pair of end-coupled uniform transmission lines with equal-length on the top and an OLDS outline symmetrically was etched in the ground plane. In addition, by introducing cross-shaped lines, a dual band function is achieved. In the proposed structure, in order to reject the unwanted harmonic pass bands, step impedance transmission lines are implemented along the ports of the filter. The fabricated filter has the merits of simple topology, compact size, good return loss, low insertion loss and high isolation. The measurement agrees well with the simulation.
