先進駕駛輔助系統(Advanced Driver Assistance Systems；ADAS)，是近年來各車廠積極發展的智慧車輛技術，而車用雷達系統是先進駕駛輔助系統中非常重要的部分。
本論文研發應用於停車防撞雷達系統中的被動元件，包含鼠線耦合器與寬半功率波束頻寬之天線。提出一個新的方法來改良傳輸線的等效電路模型，並透過使用集總式元件的方式，在積體被動元件製程(IPD)與晶圓級封裝技術(WLP)上設計鼠線耦合器，藉此達到電路微小化的效果。
同時在封裝基板上設計天線，讓整個雷達系統能在一個封裝上完成整合，透過使用接地的寄生元件方式，讓微帶天線E平面半功率波束頻寬變得更寬，以增加系統能偵測的角度。

In recent years, the Advanced Driver Assistance Systems (ADAS) are the smart vehicle technology that the vehicular manufacturers actively develop. The automotive radars are important parts in the ADAS.
In this paper, we study the passive components used in parking anti-collision radar system, including the rat race coupler and wide half-power-beam-width parasitic patch antenna. We proposed a new method to improve the equivalent circuit model of transmission line section for T-coil structure, and we used lumped circuits to design the rat race coupler on integrated passive component process and re-distribution layer of wafer level package process to achieve the compact circuit size.
At the same time, we design the patch antenna on the package substrate to make the whole radar system integrated on a substrate. We used the grounded parasitic components to enhance the half power beam-width of E-plane of the patch antenna to increase the detection angle of the system.
