摘要
提出了一种新型的50-ΩPBG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,此种PBG结构的阻带宽且深,同时通带的波纹较小,与在金属导带或金属接地板上刻蚀周期性方孔的PBG微带线相比,该新型PBG结构的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.
A novel PEG microstrip line was proposed. The formation of proposed structure is due to the periodical to change of the width of the conductor line. The stopband is deep and wide, the ripple of passband small, and the S-parameter characteristics of the novel PBG microstrip line are better when compared with conventional PBG microstrip line with holes etched in the conductor line or in the earth-plate. The simulation of novel PBG microstrip line has been justified by practical measurement.
