在本論文中，我們設計一操作頻段在76GHz ~ 81 GHz之微帶天線應用在多輸入多輸出(MIMO)車用調頻連續波(FMCW)之雷達上。本篇論文目標在於設計一輻射場型在垂直面上是窄的波束，水平面則是寬的波束，並在76GHz ~ 81 GHz頻段中輻射場型保持穩定讓後端FMCW雷達系統計算距離與角度更精準。此天線陣列由4排天線次陣列組成，每一排次陣列由八個串聯饋入(series fed)之微帶天線組成串接微帶天線次陣列。最後實作天線出來，量測出來的垂直面方向波束寬約10度，在水平面方向波束寬約80度。

In this thesis, we design a planar printed microstrip antenna operating in frequency band of 76GHz to 81GHz for frequency modulated continuous wave (FMCW) multiple-input multiple-output (MIMO) array radar. The goal of this thesis is to design a radiation pattern with a narrow beam in the vertical plane, a wide beam in the horizontal plane and being stable in 76GHz to 81GHz, which keeps the back-end FMCW radar system to calculate distances and angles precisely. The antenna array is composed of 4 rows of antenna sub-arrays, and each row of sub-arrays is composed of eight series fed patch antenna. Finally, the measurement results of the antenna, the main beam of E plane about 〖10〗^° and the main beam of H plane about 〖80〗^°.
