摘要
根据共面紧凑型光子晶体的原理和HFSS仿真结果设计了禁带位于超宽带(UWB,3.1~10.6 GHz)范围的EBG(电磁波带隙)结构,然后采用低温共烧陶瓷(LTCC)工艺制备出了设计的EBG结构。利用光学显微镜和扫描电子显微镜观察了所制EBG结构的微观结构,结果显示烧结体中陶瓷与银电极结合良好。另外,经HP8720ES矢量网络分析仪测试发现其电磁波禁带位于4.0~5.5 GHz,深度大于20 dB。
An EBG (Electromagnetic wave band-gap) structure with its band-gap failing in ultra-wideband (3.1 -1 0.6 GHz) was designed based on the theory of uniplanar compact photonic crystals and the HFSS simulation results. The designed structure was then fabricated using low temperature co-fired ceramics (LTCC) technique. The microstructure and properties of the prepared EBG structure were studied with optical microscope, scanning electron microscope and HP8720ES vector network analyzer. The results show that there is a good connection between ceramic and Silver in the sintering body. The band-gap of the EBG structure falls in the range of 4.0-5.5 GHz, with the band-gap depth above 20 dB.
