A Novel Compact CPW LowPass Filter Integrating Periodic Triangle DGS Cells

Abstract

In this paper, we introduce a new periodic structure for CPW of a low pass filter based on the DGS technique with triangle slot cell forme. The proposed structure is a minuature low pass filter that exhibits low insertion loss in the passband, simple fabrication, and easy to integrate with microwave planar circuits.A Lowpass filter (LPF) has been designed with flat response at a selected frequency by cascading three DGS cells.

Miniaturized ultra-wideband coplanarwaveguide lowpass filter with extended stop band

“…In order to reach an accommodation between size and performance, both DGS with different configurations and slot lines, together inserted in coplanar waveguides lines (CPWs) are other important procedure for the realization of resonators and filters for microwave and millimeter-waves circuits [13][14][15]. Some compact structures based on periodic structures of DGS configuration and other based on periodic slots have been proposed to construct a slow-wave transmission line and has been used in the design of a miniature low-pass filter [16,17]. This paper translates our efforts to design and develop a miniaturized ultra wide band…”
