In this paper, we proposed a new compact microstrip low-pass filter with broad stopband and sharp skirt characteristics. The philosophy of the structure behind this novel microstrip low-pass filter is simple as it is composed of a pair of parallel coupled-line and an open-stub. With this configuration, a finite attenuation pole near the stopband cutoff frequency is available, and the notch frequency can be well controlled by adjusting the circuit parameters. The design formulas are derived by… CONTINUE READING
