Design of Novel UWB Coupled Line Band Pass Filter with Improved Stop Band Performance
As we know that the conventional filter synthesis procedure is adequate only for the relatively narrow band filters and is not suitable for the Wideband and Ultra wideband filters .Therefore we are intend to design a Ultra Wideband filter. In this study a compact Ultra Wide Band pass filter consisting of quarter wave resonant conductor like micro strip lines is proposed to design. We have to in...
متن کاملAn Example of Suppression of Spurious Stop-Bands of EBG Band-Stop Filter
Based on the well known theory of infinite periodic structures, analytical theory of EBG (electromagnetic band gap) cells suppressing 6 higher (spurious) stop-bands is developed. Using such cells in a cascade the straight-forward procedure for design of the corresponding EBG band-stop filter is proposed, with possibility to control the width and the depth of the stopband. The analytical theory ...
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 کاملA W-Band Waveguide Band-Stop Filter Using Electromagnetic Crystal (EMXT) Surface
A rectangular waveguide band-stop filter using electromagnetic crystals (EMXT) surface as the top and bottom walls is presented in this letter. The EMXT surface has a band gap that can prevent electromagnetic wave from propagating along the waveguide. Dispersion properties of the waveguide filter are analyzed using an approximated lumped-element circuit model. A W-band prototype based on the pr...
متن کاملIIR Band Pass and Band Stop Filter Design employing Teaching-Learning based Optimization Technique
In this paper newly developed teaching-learning based optimization (TLBO) algorithm is applied for designing band pass (BP) and band stop (BS) digital IIR filters. TLBO is heuristic algorithm based on the social phenomenon of teaching-learning process. The effectiveness of purposed algorithm is validated by designing the BP and BS filters by approximating the magnitude response with Lp-norm err...
