本研究是採用介質合成波導(Substrate Integrated Waveguide)設計羅特曼透鏡(Rotman lens)，並使用多層板技術整合天線陣列(Antenna Array)，其工作頻率設定為76GHz到81GHz，由於高頻電磁波路徑損耗較為嚴重，因此羅特曼透鏡使用介質合成波導設計，而天線將採用陣列形式提高增益，彌補路徑帶來的損耗。為了整合天線陣列與波束掃描(Beam Scan)電路，並大幅縮小尺寸，故使用天線封裝(Antenna-in-Package,Aip)與多層板疊構技術。
本論文選擇微帶天線，並使用串接錐形天線陣列(Series-Fed Taper Antenna Array)設計，抑制旁波瓣位準(Side Lobe Level,SLL)。

This thesis mainly studies, the Substrate Integrated Waveguide is used to design the Rotman lens, and the multi-layer board technology is used to integrate the antenna array (Antenna Array). Its operating frequency is set to 76GHz to 81GHz.
Since the path loss of high-frequency electromagnetic waves is more serious, the Rotman lens uses a dielectric waveguide design, and the antenna will adopt an array form to increase the gain and make up for the loss caused by the path.
This study uses a multilayer board to integrate the antenna array and the Beam Switchable circuit, which greatly reduces the size, the Antenna-in-Package (AIP) and multilayer board stacking technology are used.
In this study, the microstrip antenna is selected and the Series-Fed Taper Antenna Array design is adopted to suppress the side lobe level.
