| Summary: | 碩士 === 國立交通大學 === 電信工程研究所 === 107 === 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〗^°.
