dc.description.abstract本论文为开发W-频段导波管鳍线带通滤波器组装结构之改良设计与W-频段鳍线双工器之实现与制作,本论文所选用的板材为Rogers RT-Duroud 5880TM,其基板厚度为5mil、介电常数为2.2、耗损正切为0.0009。滤波器设计程序为:首先先决定滤波器的中心频率、比例频宽、与滤波器阶数。之后利用上述参数求得柴式低通原型滤波器之参数,再转换成带通滤波器各腔之间的耦合系数与外部品质因数。最后利用3D模拟软体HFSS模拟组合之,如此整体滤波器架构得以实现。本论文中之滤波器有两种中心频率85GHz和94GHz。其中又分为单面式鳍线滤波器比例频宽为3%的三阶及四阶鳍线滤波器,及双面式鳍线滤波器比例频宽为1%以及比例频宽为3%之三阶、四阶鳍线滤波器,并导入所提的改良式组装架构使其于实作量测时可以有更好的量测结果。在双工器设计部分除了传统T型架构,在本论文所使用为双岔型(Bifurcated)架构,并设计85GHz-94GHz单面式3%三阶之带通滤波器,并利用电路模拟软体ADS简化我们的模拟流程,使模拟流程更为顺利,并探讨如何设计一种机壳使其通用于其他阶数及单双面式架构双工器。zh_TW
dc.description.abstractIn this thesis, we develop the improved mounting structure of a W-band waveguide finline bandpass filter and realize the bifurcated finline diplexer. The proposed W-band finline bandpass filter are implemented with Rogers RT-Duroud 5880TM substrate with a dielectric constant of 2.2, a thickness of 5mil, and a loss tangent of 0.0009. The design procedures of the waveguide finline filter are briefly described as following. Firstly, decide the center frequency, the fractional bandwidth, and the order of filter. Then, obtain the Chebyshev low-pass prototype parameters, and transfer these low-pass prototype parameters into a series of coupling coefficients and external quality factor. Finally, by using the 3D EM simulation software HFSSTM get the physical dimensions of the filter. The finline bandpass filters are designed with the center frequencies of 85GHz and 94GHz. The filters are categorized as the unilateral finline filter with 3-orser and 4-order and a fractional bandwidth of 3%, and the bilateral finline filter with 3-order and 4-order and a fractional bandwidth of 1% and 3%. All of the filters are with the proposed mounting structure to improve the repeatability of the assembling process. Applying the bifurcated structure, we design a diplexer with center frequencies of 85GHz and 94GHz both with a unilateral 3-order and 3% filters. In order to improve the efficiency of simulation, we use circuit simulation software ADS combined with the HFSS to simplify our simulation process.en_US
