Compact LPF using T-shaped resonator with sharp roll-off and ultra wide stopband
In this paper, a microstrip lowpass filter with an ultra-wide stopband with sharp roll-off and compact size is designed and fabricated. To provide a very small dimension, T-shaped and stepped impedance have been used. The cut of frequency at -3 dB is 3.1 GHz. In the proposed structure, insertion loss is less than 0.12 and return loss is more than 15 dB. To achieve a -20dB attenuation level...
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 کاملMicrostrip Low-pass Filter with Sharp Roll off and Wide Stop-band Using Multiple Cascaded Modified Radial Stubs Resonators
This paper presents a novel microstrip low-pass filter with good performance. A complete detailed theoretical analysis for the proposed filter is given using equivalent circuit models. The proposed filter applying multiple cascaded modified radial stubs resonators provides a sharp cut off frequency response that has a 185 dB/GHz roll off rate. Also, U-shaped attenuators provide a wide stop-band...
متن کاملAnalysis of Novel Approach to Design of Ultra - wide Stopband Microstrip Low - Pass Filter Using Modified U - Shaped Resonator
© 2015 Gholamreza Karimi et al. 945 http://dx.doi.org/10.4218/etrij.15.0114.0188 A novel microstrip low-pass filter is presented to achieve an ultra-wide stopband with 11 harmonic suppression and very sharp skirt characteristics. The filter is composed of a modified U-shaped resonator (which creates two fully adjustable transmission zeroes), a T-shaped resonator (which determines a cut-off freq...
متن کاملA Novel Compact Microstrip Lowpass Filter with Sharp Transition and Improved Stopband
A novel compact microstrip lowpass filter (LPF) is proposed in this paper, which consists of the complementary rectangle split ring defected microstrip structure (CRSR-DMS), open stubs, spurline and the dumbbell-shaped defected ground structure (DGS). Due to the unique response of the presented CRSR-DMS, a low passband insertion loss and a sharp transition of the proposed LPF was achieved. Mean...
