本篇論文主要在研究E-Band波導濾波器的設計。本文設計出的兩個濾波器可分別涵蓋80GHz常用的兩個頻率範圍71~76GHz及81~86GHz. 本論文也一併探討了模擬製造過程中可能產生的公差分析來產生更精準的設計。設計初期先以電磁模擬軟體(Wasp-Net)計算出理想共振腔尺寸，插入損耗及反射損耗。再透過另外一套電磁模擬軟體(HFSS)重覆模擬現有尺寸來驗證模擬的精準度。
本論文也將透過模擬軟體的公差分析，來預測加工上可能產生的的尺寸誤差所造成的電性衰減. 我們可依此分析預測濾波器實際量測的性能。比對模擬與實際量測之結果，十分接近。可知在模擬階段，加入製造過程之公差分析，便可預測濾波器的量測結果。此設計方法可有效降低製造打樣之往返，符合最佳電性要求，並減少時間與成本上的浪費。

This thesis is mainly discussed in E-Band waveguide filter design. This design of the two filters can meet the common used 80GHz frequency range 71-76GHz and 81-86GHz separately. The thesis also discusses the tolerance analysis may occur in the manufacturing process to make the design more accurate.
In the preliminary design, we will use electromagnetic simulation software (Wasp-Net) to calculate the ideal cavity size, Insertion Loss and Return Loss. By using another electromagnetic software (HFSS) to calculate current size to validate the accuracy of the simulation.
This thesis also do the tolerance analysis of simulation to predict electrical performance degrade due to mechanical error in manufacturing process. We could use this analysis to predict the filter’s measurement.
Since the simulation and actual measurement results are very close.
We could add the tolerance analysis of the manufacturing process in simulation to predict the measured results. This design method can effectively reduce the manufacturing proto-type round, in line with the best electrical requirements, and reduce the waste of time and cost.
