本論文包含毫米波雷達系統之微型化饋入架構與陣列天線設計以及兩款連接器設計，可應用於第五代無線通訊系統。
第一部份為微型化毫米波雷達天線設計，首先為可應用於毫米波雷達系統之微型化饋入架構，此架構利用精密加工方式，在鋁塊中放入介質鐵氟龍及內部導體作為連接77/79 GHz雷達IC模組與天線間之同軸電纜結構，而此饋入架構具有低傳輸損耗、高天線設計自由度、以及可藉由鋁塊達到散熱效果之優點。其次為針對大範圍三維涵蓋應用提出一款槽孔矩型貼片天線設計，並將天線分別設計應用於60與77/79 GHz兩種不同毫米波頻段。再次，本研究亦針對應用於77/79 GHz雷達系統之串列式槽孔貼片陣列天線進行設計與量測驗證。最後，本研究整合上述同軸饋入架構以及串列式天線來分析其整體效能。此外，本研究進行了毫米波雷達系統實測來驗證其偵測效能。
第二部份則提出兩款連接器設計，內容包含應用於光電通訊系統之DSFP高速連接器以及汽車產業客制化Ouster連接器的設計。首先為DSFP高速連接器，其單通道支援頻率為0–28 GHz，若搭配PAM4調變方式，單通道傳輸速率將可達100 Gbps，由於此連接器具有上下兩通道，因此單顆連接器傳輸輸率可達200 Gbps，以滿足5G無線通訊之高速傳輸需求。接續為Ouster連接器設計，此連接器為基於Cat-5e客製開發圓型連接器，主要用於車載診斷系統，雖然此款連接器應用頻率並不高，但仍然具有高度耦合串音干擾效應，需要針對串音抑制進行改善。

This thesis contains the design of the miniaturized feeding structure and array antenna for the millimeter-wave radar system, and also two connectors which can be applied in the 5th generation wireless system.
The first part is the design of the miniaturized millimeter-wave radar antenna. Firstly, a miniaturized feeding structure that can be applied for millimeter-wave radar system is studied. A copper wire covered with Teflon is put into an aluminum block to form a coaxial line structure connecting the 77/79 GHz radar IC module and the antenna. Thus, the feeding structure may have low transmission loss, more flexible antenna design, and the advantage of the heat dissipation through the aluminum block. Secondly, a cavity-back patch antenna design is proposed for a wide range of three-dimensional coverage applications for 60 GHz and 77/79 GHz millimeter-wave bands, respectively. Thirdly, this study also carries out design and measurement verifications for series-fed cavity-back patch antenna applied to 77/79 GHz millimeter-wave radar system. Finally, the feeding structure and series-fed patch array antenna mentioned above are integrated to analyze overall performance. In addition, the measurement of the millimeter-wave radar system is conducted.
The second part proposes two connector designs, including the DSFP high-speed connector for optical electrical application and Ouster connector for the automotive industry. Firstly, for DSFP high-speed connector design, every high-speed channel of the connector supports frequency range up to 28 GHz. With the PAM4 modulation technique, the transmission rate of the DSFP can reach 100 Gbps. Because this connector has two channels, the total transmission rate is 200 Gbps to meet the high-speed transmission requirements in the 5G wireless communications. As for Ouster connector. it is a custom-made circular connector based on Cat-5e, mainly used in on board diagnostics. Although the application frequency of this connector is not high, it still has a significant coupling crosstalk interference to be improved in this study.
