Development of Compact Ultra-Wideband (UWB) Microstrip Bandpass Filter
Miniaturized Ultra-Wideband (UWB) microstrip bandpass filter with wide passband is presented. The filter is developed based on modified multiple mode resonator, which is formed by transversely attaching three pairs of non-uniform and folded stubs with lowpass and highpass sections. Both sides of high-impedance section are linked with two feed lines via direct coupled lines, resulting UWB bandpa...
متن کاملCompact Ultra-Wideband Microstrip Bandpass Filter Using SIR Approach
Planar band pass filters (BPF) with low insertion loss, compact size, high selectivity, wider bandwidth and good stop band rejection are required for the next generation mobile and satellite communication systems. In the case of the planar filter solution, electrical performance with regard to both out-of-band rejection and in-band transmission losses, as well as cost, reliability and dimension...
متن کاملCompact 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 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...
متن کاملUltra-Wideband Bandpass Filter Using Hybrid Microstrip-Defected-Ground Structure
A novel ultra-wideband (UWB) bandpass filter (BPF) with a fractional bandwidth (FBW) of about % 110 is presented using the hybrid microstrip-defected-ground structure (DGS). The proposed filter was designed using a combination of hybrid microstrip-defected-ground structure lowpass filter (LPF) with typical quarter-wavelength short-circuited stubs highpass filter (HPF), followed by an optimizati...
