Compact and Wide Stopband Lowpass Filter Using Open Complementary Split Ring Resonator and Defected Ground Structure
A compact (0.16 g × 0.08 g) and wide stopband lowpass filter design using open complementary split ring resonator (OCSRR) and defected ground structure (DGS) is presented in this paper. Low pass filter is constructed using two cascaded stages of OCSRR. Since the rejection bandwidth of the OCSRR is narrow, tapered dumbbell shaped DGS section is placed under the OCSRR to enhance the bandwidth. Th...
متن کاملMiniaturized Wideband Bandpass Filter with Wide Stopband using Metamaterial-based Resonator and Defected Ground Structure
This paper presents a miniaturized wideband bandpass filter with wide stopband performance. It is shown that the coupled metamaterial-based resonators (MBRs) incorporating with the defected ground structure (DGS) can significantly increase the coupling value to achieve wideband bandpass filter. This technique has been extended to realize wideband bandpass filter having fractional bandwidth of 6...
متن کاملA Miniaturized Directional Coupler Using Complementary Split Ring Resonator and Dumbbell-Like Defected Ground Structure
A novel microstrip coupled-line directional coupler is proposed in this paper. It is based on the introduction of a complementary split ring resonator and dumbbell-like defected ground structure on the coupled lines to strongly enhance the designed backward coupling. The designed frequency band is from 1.2 to 1.5GHz. The coupler is fabricated and tested. The insertion loss is less than 3.5 dB. ...
متن کاملCompact Microstrip Lowpass Filter with Sharp Roll-off and Wide Stopband Using Semicircle Ended Stub Resonator
In this paper, a semicircle ended stub resonator, cascaded to a modified radial patch to design a compact lowpass filter with sharp roll-off and wide stopband is proposed. This filter has 3 dB cutoff frequency at 1.54 GHz. The transition band is only 0.26GHz from 1.54 GHz to 1.8 GHz with corresponding attenuation levels of −3 dB and −20 dB respectively. Maximum insertion loss is 0.1 dB in the p...
متن کاملCompact microstrip lowpass filter with very wide stopband using open stubs loaded with defected front coupled tapers
A novel microstrip lowpass filter is proposed to achieve a very wide stopband and high selectivity as well as compact size. This filter utilizes a resonator with symmetric structure that consists of a transmission line, loaded with open stubs. Each stub ends with a defected taper and these tapers are coupled two by two to generate enhanced capacitances and increase the selectivity. Two units of...
