Novel tuneable dual-mode narrowband bandstop filter using loaded microstrip resonator is presented. The filter is designed by using coupled line coupling with the microstrip resonator. There is two different pair of loaded resonator that produces a dual band bandstop filter. The dual band bandstop resonance frequency can be tuned independently by adjusting the resonator width and length. To achieve...
This paper presents a microstrip planar resonator sensors for accurate dielectric measurement of microfluidic solutions based on split ring resonator approach. A potential technique for characterization of solvents with the microvolume of samples has been investigated. The proposed design structures are focusing on a high Q-factor (>400) which operates at 2.0 and 2.2 GHz. The characterization principle...
This paper presents the design and optimisation of film bulk acoustic wave resonator (FBAR) using nano electro mechanical systems (NEMS) technology in 10–20 GHz frequency band. The effect of thickness, width and length and damping factor of the FBAR are analysed. The air-gap FBAR are designed due its ability to achieve high quality (Q) factor in 10–20 GHz frequency band. The proposed designs achieve...
A deep attenuation level and wide stopband bandwidth, sharp roll-off and low insertion loss in the passband using H-shaped defected microstrip structure (DMS) at open circuit stub resonator (OCSR) of the stepped-impedance low pass filter (SILPF) is presented in this paper. The proposed filter consists of H-shaped that is etching at the microstrip line of OCSR. The OCSR is embedded in the middle of...
