【摘要】 本文提出了一种新型的50Ω光子带隙(PBG)结构微带线,该PBG结构的制作是周期地改变金属导带的宽度,同时在金属接地板上刻蚀圆孔,此种PBG结构可以获得窄的通带或宽的阻带,其微带线的通带和阻带的宽度可按照设计者的要求改变。本文设计、制造和测量了两个新型的PBG结构微带线,并通过仿真验证这种新型PBG结构的仿真结果得到了实验的验证。更多还原

【Abstract】 A novel photonic bandgap (PBG) structure for 50Ω conventional microstrip line is proposed. The PBG structure is fabricated with periodic rectangles etched on the edge of conductor line and circle holes etched in the ground plane for one microstrip. The narrower passband or wider stopband can be realized with the PBG structure. The bandwidth of stopband or passband can be changed according to requirement. Two new PBG structure microstrip lines with periodic rectangle etched on the edge of conductor line and circle holes etched in the ground plane are designed, fabricated, and measured. Measurement data of this novel PBG microstrip line agrees well with simulations.更多还原
