基于传统的十字型结构,设计了一种可工作在太赫兹大气通信窗口的超介质十字型阵列多层带通滤波器,中心频率为338GHz,中心频点的透射率为94.7%,并讨论了十字型滤波器的传输特性与稳定特性。运用圆形贴片对十字型超介质滤波器进行改进构成复合十字型超介质滤波器。结果显示,中心频点的透射率为95.8%,3dB带宽为73.72GHz,且对不同的极化方式不敏感,并在30°范围内频率响应稳定。
Based on the traditional cruciform structure, a supercapacitor cross-shaped multi-layer bandpass filter with a center frequency of 338GHz and a center frequency of 94.7% is designed and designed to work in a terahertz atmosphere communication window Transmission characteristics and stability of cross filter. The use of circular patch on the cross-type super-dielectric filter to improve the composite cross-type super-dielectric filter. The results show that the center frequency of the transmittance of 95.8%, 3dB bandwidth of 73.72GHz, and the polarization is not sensitive to different methods, and within 30 ° frequency response stable.
