本論文包含三項研究主題，第一部分為應用於車用雷達系統之天線設計，其中搭配德州儀器(TI)的IWR1642雷達模組，所開發陣列天線較原公版設計天線，具有較高輻射效率且較不受金屬表面製程影響之特色。第二部分探討應用於Ka頻段低軌道衛星通訊系統之陣列天線設計，其中為了降低極化偏轉的影響，乃採用圓極化設計，而為求寬頻的匹配與軸比，並選用雙饋入與槽孔耦合方式饋送至貼片天線，且提出三種連接架構來比較其效能。第三部分研發主動式天線之OTA近場量測技術，由於主動式天線自帶訊號源，因此需重建相位量測結果來獲得完整天線近場，以實測具發射源之主動式天線輻射場型。

This thesis includes three parts. The first part is about antenna designs for applications in automotive radar systems. Those antennas are embedded on the printed circuit board and connected to TI IWR1642 chips. Compared to TI original evaluation board design, higher radiation efficiency and less influence from metal surface processing are achieved. The second part discusses array antenna designs for Low Earth Orbit (LEO) communication systems. In order to reduce losses from polarization mismatch, circularly polarized antennas are designed. Also, to achieve the wide bandwidth requirement of the LEO, dual inputs and slot coupling are proposed in the patch antennas of the arrays. For performance comparisons, three types of the feeding networks are adapted. The third part studies Over The Air (OTA) near field measurement techniques for active antennas. Because the active antennas are integrated with signal sources, phase recovering is needed for the near field measurements to obtain the radiation patterns.
