设计、制作了一个四段平面带通滤波器，并在130-360 GHz进行了测试。该滤波器是基于微屏蔽线的，微屏蔽线是一种半屏蔽传输线，其中导线支撑在1.4 μ m厚的介质膜上。滤波器的插入损耗小于1.5 dB，在250 GHz处具有58%的相对带宽，证明了微屏蔽几何结构的优异性能。此外，蒙特卡洛例程开发结合半经验/半分析模型，以允许从标量功率测量导出的滤波器的S参数。
A four-section, planar bandpass filter has been designed, fabricated and tested at 130-360 GHz. The filter is based on the microshield line, a half-shielded transmission line in which the conducting lines are supported on a 1.4-μm-thick dielectric membrane. The insertion loss of the filter is less than 1.5 dB with a 58% relative bandwidth at 250 GHz, demonstrating the excellent performance of the microshield geometry. Also, a Monte Carlo routine was developed in conjunction with a semi-empirical/semi-analytical model to allow the S-parameters of the filter to be derived from scalar power measurements.
