Compact Microstrip Uwb Bandpass Filter with Triple-notched Bands
A new microstrip ultra-wideband (UWB) bandpass filter (BPF) with triple-notched bands is presented in this paper. The circuit topology and its corresponding electrical parameters of the initial microstrip UWB BPF are desired by a variation of genetic algorithm (VGA). Then, triple-notched bands inside the UWB passband are implemented by coupling a square ring short stub loaded resonator (SRSSLR)...
متن کاملMiniaturized Uwb Bandpass Filter with Dual Notch Bands and Wide Upper Stopband
In this paper, a miniature ultrawideband (UWB) bandpass filter with dual notch bands and wide upper stopband is presented. The ultrawide passband characteristic is achieved using a microstrip to slot line transition, and a wide upper stop band is realized using an elliptical lowpass filter. The dual band notches at 5.46 GHz and 8.04GHz are obtained by incorporating defected microstrip structure...
متن کاملCompact and Wide Upper-Stopband Triple-Mode Broadband Microstrip BPF
A broadband microstrip bandpass filter (BPF) with compact size, sharp skirt and wide upperstopband performance is proposed using the triple-mode stub-loaded resonator. The resonator can generate one odd mode and two even modes in the desired passband. Due to the main path signal counteraction, two transmission zeros Tz1, Tz2 can be created near the passband edge to achieve sharp skirt. Two tran...
متن کاملA Compact UWB Bandpass Filter with High Selectivity and Dual Notched-Band
A novel compact-sized ultra-wideband (UWB) bandpass filter (BPF) is proposed in this paper. The proposed BPF is highly selective and is able to eliminate WLAN signals from 5.15-5.35 GHz, and downlink of X-band satellite communication signals from 7.25-7.75 GHz. Generally, a multiple-mode resonator (MMR), comprised of a U-shaped line, with two high impedance stubs connected to it, and one steppe...
متن کاملUltra-Wideband (UWB) Microstrip Bandpass Filter with an Improved Wide Stopband
— In this paper, the ultra-wideband (UWB) bandpass filter (BPF) with a wide stopband is presented. The prototype of proposed UWB BPF is by bending the five short-circuited stubs and coupling the I/O feed lines. In order to have a wide stopband, an bandstop structure embedded in input/output (I/O) lines without degrading the passband performances is used. The measured results verified that by us...
