摘要
提出一种新型微带光子带隙结构。该结构直接在微带信号线上刻蚀周期性结构,解决了该结构的封装问题,且不增加微带结构的尺寸。采用时域有限差分法分析该结构的S参数,并研究了几何参数与S参数之间的关系,得出了禁带中心频率、带宽随几何参数变化的趋势。
A novel photonic band gap (PBG) structure is presented in this paper. With the features of easy package and not increasing the size of microstrip, the PBG units is directly etched on a microstrip line. Using the finite difference time domain (FDTD) method, the S parameters of the new structure are obtained and the relationship between geometric parameters and S parameters is studied. The variation trends of central frequency and bandwidth along with geometric parameters are also dicussed.
