Compact Lowpass Filter Design by using Triangle Shape DGS
Most communication system contains an RF front end which performs signal processing with RF filters. Micro strip filters are a low cost means of doing this. Micro strip filters play various roles in wireless or mobile communication systems. There is an increasing demand for newer microwave and millimetre-wave systems to meet the emerging telecommunication challenges with respect to size, perfor...
متن کاملUltra Wideband Seven Poles Lowpass Filter Using DGS Array
This project is intended to build a microstrip low pass filter with a pass band till 3 GHz at 3 dB cutoff frequency. This project is divided into two stages. In the first stage, a conventional seven pole low pass filter using commensurate length 8 / g λ is designed by converting the value of g1 to g7 into unit elements as well as open circuit stubs. In second stage, a method to design low pass ...
متن کاملCompact Microstrip Low-Pass Filter Design with Ultra-Wide Reject Band using a Novel Quarter-Circle DGS Shape
─ A novel quarter-circle defected ground structure shape is introduced in this paper to design and implement an ultra-wide reject band low-pass filter (LPF). Moreover, an equivalent circuit model (ECM) is presented. The proposed LPF has small size and, a low insertion loss and a return loss less than -20 dB. Also, a round -20 dB suppression level ranging from 4 GHz to more than 20 GHz is achiev...
متن کاملDesign of Compact Bandpass Filter for WiMAX and UWB Application using Asymmetric SIRs and DGS
This paper considers a novel compact tri-band microstrip bandpass filter, the design of which employs asymmetric SIRs and DGS for achieving the characteristics of low insertion loss, high selectivity, wider range of bandwidth, and low group delay for 2.5/3.4 GHz (WiMAX) and 4.14–5.32 GHz (UWB) bands. The novel filter design implies the intentional selection of impedance ratio R and the length o...
متن کاملDevelopment and Analysis of Compact Lowpass Filter for UWB Systems
This paper presents a developed compact lowpass filter which is devised by concatenating ‘T’ and inverted ‘T’ open stubs on a microstrip line. They are combined to enhance the bandwidth and also to improve the outband performance. Insertion loss of the developed filter is less than -0.15 dB and the return loss is -30 dB at 2.85 GHz. Stopband performance of the filter is less than -20 dB from 5....
