Title The propagation properties of millimeter-wave in planar waveguide
Abstract
Substrate integrated waveguide (SIW) is a novel waveguide structure with advantages of low loss, low radiation, high Q factor and high power capacity like rectangular waveguide, and compact and easy integration as microstrip line, has a bright future in applications. SIW is widely used in microwave and millimeter circuits, so it becomes one of the key points in microwave field.
Firstly, the propagation characteristics for SIW are analyzed. Secondly, the equivalence relation between SIW and rectangular waveguide is derived, and the principles and method to design a SIW is proposed on the basis of formula of effective width. Finally we have tested the propagation characteristics of SIW, indicating the similarity between these two structures.
SIW (Substrate Integrated Waveguide) is one kind of integrated non-planar transmission line, its measurement and integration with other circuits need a transition from SIW to microstrip. On the basis of SIW, the transition to microstrip and CPW is analyzed, and the design and simulation of the transition from SIW to microstrip is carried out.
Keywords：Substrate Integrated Waveguide (SIW), regular waveguide (RW), microstrip Line (ML), coplanar waveguide (CPW) , microwave transition
