چکیده
A combination of lowpass and dual band bandpass filter with improved selectivity is presented in this manuscript. Two circular split ring resonators which are connected at the upper side, provide a characteristics. In order to achieve combined passband response two L-shape stubs incorporated into structure. The parametric analysis proposed has been carried out using CST microwave studio. numerical result shows 3-dB cutoff frequency for 1.22 GHz, first second resonant frequencies 2.44 GHz 3.7 respectively. compact overall size 32.9 mm?15mm.

Novel Compact Dual - Band Bandpass Microstrip Filter
In this paper, a novel microstrip structure is developed to realize a dual-band bandpass filter. The proposed bandpass structure uses a microstrip resonator with two independently controlled resonance frequencies producing two frequency bands of interest controlled by adjusting the dimensions of the resonator. Parametric analysis is performed on the structure to determine the optimum dimensions...
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 کاملCompact Dual-Band Bandpass Waveguide Filter with H-Plane Inserts
A novel compact dual-band bandpass waveguide filter is presented in this paper. H-plane metal inserts with complementary split-ring resonators are implemented as resonating elements in the standard (WR-90) rectangular waveguide. Design starts from the models of the waveguide resonators with two resonant frequencies (9 GHz and 11 GHz) using a single flat or folded metal insert. Further, folded i...

متن کاملA Compact Band-selective Filter and Antenna for UWB Application
Abstract— A novel compact CPW ultra-wideband (UWB) antenna combined with a compact band-selective filter is proposed. The proposed antenna without filter satisfies the return loss requirement of less than −10 dB over the frequency range of 3.0 GHz to 12.1GHz. The optimized antenna has dimensions of 10×16mm2 on a Teflon substrate (εr = 3.48) with good radiation characteristics and is easy to fab...
