Compact Microstrip Lowpass Filter with Wide Stopband and High Attenuation
A compact microstrip lowpass filter using radial stub resonators is developed. This filter is composed of two radial stub resonators that are asymmetrically connected to each other by a stepped impedance structure. This structure results in a very high rejection and wide stopband. The proposed filter with a 3 dB cutoff frequency of 2.07 GHz has been designed, fabricated and measured. Measuremen...
متن کاملDesign of Compact Microstrip Low-pass Fil- Ter with Ultra-wide Stopband Using Sirs
Abstract—A novel low-pass filter (LPF) is designed and fabricated based on stepped-impedance resonator (SIR). Semi-circles are used to reduce the size of the filter. The open-circuited stubs are used in the filter, and its simplified equivalent circuit is also proposed. The measured 3 dB cutoff frequency is 5.2GHz with no more than 0.3 dB ripple level in the pass-band. From 5.5 to 14 GHz, the i...
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 کاملCompact Microstrip Lowpass Filter With Ultra-Wide Stopband Using Patch Resonators and Open Stubs
A compact microstrip lowpass filter with ultra-wide stopband characteristics and high suppression level is presented. To achieve compact size and wide stopband suppression along with improved impedance matching, symmetrically loaded resonant patches, open stubs and stair shaped high impedance stub are introduced in the filter. The measurement results show good agreement with the simulations. Th...
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...
