摘要
A microstrip-based Ultra-Wideband Bandpass filter with a controllable notch and suppressed stopband is proposed. Dumbbell-shaped defected ground structure (DGS) etched in the ground and the double equilateral-U (DEU) DGS units under the input and output feeding lines provide the controllable notch and suppressed stopband, respectively. For optimum design of both the DGS (Dumbbell and DEU), a notch at WLAN frequency of 5.8 GHz and simultaneous stopband till 18 GHz is reported. Experimental results are in favor of the simulated data.
