【摘要】首次提出了一种新型的50Ω光子带隙(PBG)结构微带线。该PBG结构的制作是在金属导带边缘周期地刻蚀矩形和梯形结构,其微带线的阻带较深、较宽,且通带的波纹较小,与在金属导带或金属接地板上刻蚀周期性孔的通常PBG微带线相比,该新型PBG结构微带线的S参数特性较好。这种新型PBG结构的仿真结果得到了实验的证实。更多还原

【Abstract】 A novel photonic bandgap(PBG) microstrip line for 50 Ω conventional microstrip line is proposed for the first time.The proposed structure is formed by etching rectangle or trapezium on the edge of the conductor line periodically.The stopband of the novel PBG microstrip line is deep and wide,and the ripple of passband is small.The S parameters of the novel PBG microstrip line is better comparing with conventional PBG microstrip line with holes etched in the conductor line or in the ground plane.Measurement data of this novel PBG microstrip line agrees well with simulations.更多还原
