An Ultra-Wide Stop-Band LPF Using Asymmetric Pi-Shaped Koch Fractal DGS

Defected ground structure (DGS) with symmetrical geometry has been widely adopted in low-pass filter (LPF) designing, while asymmetrical geometry DGS can exhibit some specific features on transition band and stop-band. A novel asymmetrical Pi-shaped DGS with Koch fractal curve is proposed in this pa...
