Design of Compact Coupled Microstrip Line Band Pass Filter with Improved Stopband Characteristics
A compact symmetrical band-pass filter design using coupled microstrip line is presented in this paper. The microstrip line sections connected to the two input and output ports of the filter structure are printed over the Defected Ground Structure (DGS). The proposed symmetrical structure offers a simple and compact design and exhibits improved stop-band characteristics in comparison to the con...
متن کاملA Compact Microstrip Low-Pass Filter Using D-CRLH Transmission Line with Ultra-Wide Stopband and High Selectivity
A novel structure of dual-composite right/lefthanded transmission line (D-CRLH TL) is proposed and analyzed in this paper. The simulated results show that there is a stopband between the first right-handed passband and the left-handed passband of the proposed D-CRLH TL. This stopband characteristic is applied to improve the electromagnetic performances of low-pass filter (LPF). A planar compact...
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 Low Pass Filter Design for L-Band Application
An effective technique to design compact low pass filter has been proposed in this paper. The proposed method is highly effective for L-band applications. Low impedance microstrip lines are arranged such that they work as open stubs to increase the selectivity of the filter. Using the proposed technique about 57% size reduction has been realized with sharper roll off characteristics. An empiric...
متن کاملCompact 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...
