The PBG structure was fabricated with periodic rectangle holes etched on both the metal conductor line and the metal ground plate of the microstrip. 该结构是同时在金属导带和金属接地板上刻蚀周期性的矩形孔形成的。
The ACSL electrical-waveform generator consists of two striplines coupled through an aperture in their common ground plane. 一个电脉冲整形器由两条通过其公共接地板上的耦合孔径发生耦合作用的带状传输线所组成的四端口装置。
