摘要基片集成波导( SIW)具有低插损、高Q值、易于集成等优点,作为一种新型的导波技术已经被广泛地用于微波与毫米波电路。随着研究深入,一种新的导波结构———半模基片集成波导(HMSIW)被提出,与基片集成波导相比,半模基片集成波导保留了基片集成波导的优点,同时在尺寸上缩小近一半。本文用ansoft HFSS对半模基片集成波导进行建模,研究其侧壁泄露特性。比较不同厚度的介质基片材料仿真结果,并且解释介质基片材料厚度不同对侧壁泄露的影响。64593

Title leakage from the side wall of Half Mode Substrate Integrated Waveguide(HMSIW)
Abstract As low insertion loss(IL), high Q, high integrated level, substrate integrated waveguide ( SIW) has already been widely used in the design of integrated microwave and millimeter circuits. With the in-depth study, a novel guide wave structure named " half mode substrate integrated waveguide (HMSIW) " is reported.The new structure could keep the original performance of SIW with nearly a half reduction in size. In this paper,model HMSIW by ansoft HFSS and research the characteristic of leakage from the side wall. Compare simulation results of different thickness of the dielectric substrate material,and explain the thickness of substrat influence on the leakage from side wall.
