Abstract

In this work, we proposed a new design method for five-pole Hi-Lo LPF using the three DGS slot and one capacitivety compensated transmission line. A new proceeded is developed, in order to obtain a simple transformation from circuit to equivalent DGS slot. The proposed DGS Hi-Lo low-pass filters also have wider and deeper stopband characteristics than those of conventional low-pass filters. The measured results of Lowpass filters agree well with simulation results.
