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 کاملDesign of Ultra-wide Stop-band Dgs Low-pass Filter Using Meander- and Multilayer- Techniques
This article presents a new dog-bone defected ground structure (DGS) for low-pass filter (LPF) applications with widerejection band and low-insertion loss in the pass-band region. The prototype LPF consists of three dog-bone cells in the ground plane with an open stub on the top layer acting as a compensated capacitor. The prototype LPF is then realized as a multilayer structure to enhance the ...
متن کاملNew Antenna with Fractal Shaped DGS for Emergency Management Applications
An analysis and design of a novel planar antenna in corporation with fractal shaped defected ground structure (DGS) for emergency management has been presented in this paper. The conventional ground plane can be replaced by a Fractal DGS ground plane to get miniaturization and better resonating characteristics. Particle swarm optimization (PSO) has been used to identify the geometrical descript...
متن کاملAn Ultra Wide Band Simulator Using MATLAB/Simulink
Ultra Wide Band (UWB) is a promising technology for sensor networks, broadband wireless data access and location finding applications. This study outlines the development and validation of a single transmitter and receiver system across the multipath channel proposed by Saleh-Valenzuela. We have designed and tested a UWB simulator using MATLAB’s Simulink in combination with the Real Time Worksh...
