Compact Lowpass Filter Design by using Triangle Shape DGS
نویسندگان
چکیده
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, performance and cost. This paper describes a compact array of triangular shaped defected ground structure (DGS) is proposed. The dimensions of proposed compact filter are about and have very high sharpness factor (0.911). A traditional single triangular DGS structure is also design, analyzed and simulated for comparison purpose. For the design and simulation, IE3D simulation tool is used. Keywords-Low-Pass Filter, Photonic band Gap (PBG), Defected ground structure (DGS), triangular shape and Sharpness factor.

Compact and Wide Stopband Lowpass Filter Using Open Complementary Split Ring Resonator and Defected Ground Structure
A compact (0.16 g × 0.08 g) and wide stopband lowpass filter design using open complementary split ring resonator (OCSRR) and defected ground structure (DGS) is presented in this paper. Low pass filter is constructed using two cascaded stages of OCSRR. Since the rejection bandwidth of the OCSRR is narrow, tapered dumbbell shaped DGS section is placed under the OCSRR to enhance the bandwidth. Th...
متن کاملDesign and Analysis of Compact UWB Bandpass Filter with Wide Passband Using Defected Ground Structure
A compact ultra-wideband (UWB) bandpass filter (BPF) with wide passband using defected ground structure (DGS) is proposed. The proposed UWB filter is constructed by cascading a high pass filter (HPF) and a lowpass filter (LPF). HPF with short-circuited stubs is used to realize the lower stopband and a LPF is used to attenuate the upper stopband. In order to make the filter size compact, DGS tec...

The modern microwave and millimeter wave communication system demands good filtering characteristics with compact sizes. In this paper the attention has been given towards the design of a good elliptical lowpass filter with sharp transition between passband and stopband, negligible passband insertion loss and wide stop band. A new defected ground structure (DGS) consisting of two square slots c...

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...
