Abstract


RF and microwave circuits in the application of modern communication technology trend is flat , miniaturization , integration . In this paper, SIW (Substrate-Integrated Waveguide, SIW) and folded substrate integrated waveguide (Folded Substrate-Integrated Waveguide, FSIW) based on the study , analyzed the FSIW original rectangular waveguide cavity equivalence between , and derived its resonant frequency is calculated . This new quarter-wavelength cavity SIW only retains the original characteristics of the cavity , and can take advantage of more space , can be used to design a new type of microwave and millimeter wave integrated circuits. The above conclusion can be effective guidance FSIW engineering and related devices , and through the design and processing of the bandpass filter frequency response of the previous theoretical analysis verified the validity and accuracy. Also this paper summarizes the types of SIW cavity and FSIW positive and negative coupling coupling is proposed based on a novel of the same negative coupling between planes , and such coupling is used in the design of cross-coupled filter . The filter testing and simulation results agree well prove the feasibility of applying FSIW cavity . I believe that many or rectangular waveguide based on SIW ??cavity applications can also be realized through FSIW cavity , resulting in more integrated circuits or systems.
