摘要: Parallel coupled bandpass filter is proposed and designed by placing defected ground structure (DGS) in the plane. The open loop dumbbell shaped DGS used to tuned 6 GHz with a dimension of 50mm × 25mm. using FR-4 printed circuit board tuning range 0.994 achieved. This gives an insertion loss −5.784 dB return −11.051 dB. A comparison design analyzed identify better performance filter. results simulated measured discussed.
