摘要:	汽車雷達微波天線 (Microwave antenna)電路板是汽車主動雷達偵測模組供應鏈的一環，且位於tier 2 供應鏈，更是汽車微波雷達模組裝關鍵的零組件，約佔整個組裝成本10-20%材料成本。汽車雷達微波硬體模組包含發射器，其功能為生成射頻訊號；接收器，將射頻訊號管換為低頻訊號；處理器，經過運算將訊號轉換為距離、速度、角度；而天線(Antenna)負責將電能轉化成電磁波。雷達使用的頻段頻率越高，其波長越短，解析度速度和準確度會越高，這是微波雷達重要的特性。為有效降低汽車駕駛意外事故，近年來有關汽車自動駕駛功能越來越受到重視與消費者歡迎，汽車雷達電子產品應用需求也以三級跳方式於產業共應鏈中發酵，但由於急速需求下對整個產業生產與組裝未必能馬上達到最佳設計與優化生產條件。所以必須透過測試與量測電子效能來確保品質水準，這無形中增加了許多學習曲線成本，因此針對產品質與找出將低製造與品質變異的要因，進而獲得穩定的品質也提高產業利益是最為重要標的。本文主要針對汽車雷達模組的微波天線 (Microwave antenna)最佳化設計，先透過現有可控的關鍵特性項目、量測數據與微波最終效能表現分析主要因子，再應用實驗設計法針對此因子於生產中的影響找出最佳化生產條件。然影響汽車雷達效能的最重要因子天線的品質特性結構設計。本研究為探討最佳化汽車雷達天線製造條與方法，先透過研究模型建立與分析並結合田口方法找出最佳化生產設計組合，以有效提升整體汽車雷達天線電路板效能與品質。 ;The automotive radar microwave antenna circuit board is a part of the automotive active radar detection module supply chain, and is located in the tier 2 supply chain, is also a key component of automotive microwave radar module assembly, accounting for the entire assembly cost of 10- 20% material cost. The automotive radar microwave hardware module includes a transmitter, the function of which is to generate an RF signal; the receiver converts the RF signal tube into a low frequency signal; the processor converts the signal into a distance, a speed, and an angle through operation; and the antenna, Responsible for converting electrical energy into electromagnetic waves. The higher the frequency band used by the radar, the shorter the wavelength, and the higher the resolution speed and accuracy. This is an important feature of microwave radar. In order to effectively reduce automobile driving accidents, in recent years, the auto-driving function of automobiles has been paid more and more attention and welcomed by consumers. The application requirements of automotive radar electronic products are also fermented quickly in in the supply chain, but due to rapid demand. Production and assembly of the entire industry may not immediately achieve optimal design and optimization of production conditions. Therefore, it is necessary to ensure the quality level through testing and measuring the electronic performance. This inevitably increases the cost of many learning curves. Therefore, it is necessary to identify the factors that will lower the manufacturing and quality variation, and then obtain stable quality and improve the industrial interest. The most important target. This paper focuses on the optimization design of the microwave antenna of the automotive radar module. Firstly, it analyzes the main factors through the existing controllable key characteristic items, measurement data and microwave final performance analysis, and then applies the experimental design method to this factor. Find out the optimal production conditions by the impact of production. However, the most important factor affecting the performance of automotive radar is the quality characteristic structure design of the antenna. In order to explore the optimal manufacturing of automotive radar antennas and methods, this study first establishes and analyzes the research model and combines the Taguchi method to find the optimal production design combination to effectively improve the efficiency and quality of the overall automotive radar antenna circuit board.
