This article presents a novel ultra-wide bandpass filter on microstrip line with sharpened roll-off skirts, extended upper-stopband, and controllable notch-band. A shunt stub structure with two split symmetrical open end stubs is purposed, aiming to create a pair of transmission zeros at the lower and upper ends of the concerned ultra-wideband range from 3.1 to 10.6 GHz. Then, this open stub loaded with dissimilar low-impedance sections is studied to create a notch band that is located at 5.6 GHz. To further widen the upper-stopband and sharpen the roll-off skirts, an electromagnetic-bandgap structure is inserted between the two identical coupled lines. Finally, a filter prototype with notch band are designed, fabricated, and tested. Its overall size is only about 0.19 2.
