Ultra-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 کاملDesign and Analysis of Compact UWB Bandpass Filter with Wide Passband Using Defected Ground Structure
A compact ultra-wideband (UWB) bandpass filter (BPF) with wide passband using defected ground structure (DGS) is proposed. The proposed UWB filter is constructed by cascading a high pass filter (HPF) and a lowpass filter (LPF). HPF with short-circuited stubs is used to realize the lower stopband and a LPF is used to attenuate the upper stopband. In order to make the filter size compact, DGS tec...
متن کاملA Compact Ultra-Wideband Bandpass Filter with Sharp-Rejection using Complementary Split Ring Resonators
A compact and sharp-rejection ultra-wideband (UWB) microstrip band-pass filter (BPF) is developed using of left handed metamaterials realized by complementary split ring resonator (CSRR). Moreover, proposed structure consists of two doublets parallel coupling gaps at each side of a microstrip ring. In comparison with some other filters, this structure shows a significantly wider passband due to...
متن کاملMiniaturized Semi-Lumped UWB Bandpass Filter with Im- proved out-of-band performances
A miniaturized ultra wideband (UWB) bandpass filter with improved out-of band performances is presented in this paper. Based on the combination of low-pass and high-pass filters, the UWB filter is realized in a semilumped technology using microstrip transmission lines and surface mounted capacitors. In this paper, the filter design rules have been carried out. Furthermore, filters having a 3-dB...
متن کاملDesign of Planar Bandpass Filter with Wide Upper Stopband for Ultra Wideband Applications
This paper proposed a planar microstrip ultra wideband (UWB) bandpass filter (BPF) with wide upper stopband designed for applications in UWB wireless communication as stated by Federal Communications Commission (FCC). The proposed UWB filter is realized with a basic multiple mode resonator (MMR) structure feed by interdigital coupled lines for achieving higher degree of coupling. To achieve a w...
