摘要
A novel ultrawideband bandpass filter with one notch-band, high selectivity, and wide stopband is investigated in this article. The basic filter is composed of two microstrip-slot transitions with novel annular stubs, which are used to obtain the required bandwidth with high selectivity. And, a cross-coupling between the feed lines (input and output) is introduced to broaden the stopband. In addition, a short-circuited stepped-impedance resonator is used to obtain one notch-band. The simulated and experimental performances are presented in this work where good agreement is obtained.
