【Abstract】 Substrate integrated waveguide (SIW) realizes rectangular waveguide of solid structure on planar circuit substrate. It has some advantages such as high Q-factor, low loss, low cost, easily being integrated on planar circuits. Researches on the theory and technology of SIW and its applications on microwave and millimeter wave circuits have been done in this dissertation.In Chapter 1, the research backgrounds and recent developments about substrate integrated waveguide and SIW’s applications are reviewed, then its performances and design methods are summarized.In Chapter 2, firstly the realizational methods of substrate integrated waveguide and half mode substrate integrated waveguide (HMSIW) are introduced. Secondly some common methods of analyzing SIW are given. At last the propagation performances of SIW are analyzed using these methods and some designing formulae are deduced at the same time.In Chapter 3, the realizational methods and analytical theories of substrate integrated waveguide resonator are studied firstly. Secondly novel SIW and HMSIW oscillators are developed based on the principle of Gunn diode negative impedance oscillator, we can find that experimental results of these oscillators meet demands of practical engineering mostly.In Chapter 4, the impedance characteristics and electromagnetic field modes of SIW and rectangular waveguide are analyzed firstly. Broadband transitions between SIW and rectangular waveguide are designed based on impedance matching and field mode tapering. Meanwhile a coupler between coplanar waveguide and SIW is designed based on coupling theary of electromagnetic field mode.In Chapter 5, the propagation characteristics of HMSIW and electromagnetic band gap (EBG) are analyzed firstly. Based on these characteristics a broadband band-pass filter is developed. Then resonant and radiate characteristics of HMSIW are studied. Based on these characteristics, an HMSIW antenna is developed with microstrip line feeding electron.In Chapter 6, the summary of the whole dissertation is given, and future research topics are suggested.更多还原
