Microstrip Low-Pass Filter with Wide Stopband Using Coupled-Line Hairpin Unit

摘要：

A novel low-pass filter (LPF) with sharp cutoff frequency response and wide rejection bandwidth is proposed in this paper.The proposed LPF is composed of microstrip coupled-line hairpin unit, semicircle defected ground structures (S-DGS) and semicircle stepped-impedance shunt stubs (S-SISS).Sharp roll-off skirt and good out-of-band rejections are achieved as demonstrated in both simulation and experiment.
