A Miniaturized Dual-mode Bandpass Filter using Triangular Loop Resonator with Wide Stopband by U-Shaped Defected Ground Structure (DGS)

摘要

In this paper, miniaturized dual-mode microstrips bandpass filter using the triangular loop structure with harmonics suppression by double U-shaped deflected ground structure is proposed by contain excellent performance. The proposed filter shows a 3.6% f
