Abstract

SIW is a new type of integrated waveguide structure，which is similar to rectangular waveguide, high Q and low-loss．And it can be easily integrated with microstrip or coplanar waveguide．It also can be easily designed and processed so that it can be widely implemented in microwave as well as millimeter wave integrated circuits.This article describes propagation characteristics of the substrate integrated waveguide.Substrate integrated waveguide in a flexible printed circuit board and it’s filters and other passive components are simulated by HFSS.The results show that SIW is one kind of millimeter transmission line with good performance．I studied electromagnetic characteristics of the substrate integrated waveguide in a flexible printed circuit board and it’s filters.
