應用於多元通訊之漸進式槽縫天線設計與實現

本論文所研究之天線共可分為三部分，一是針對具有高指向性、高增益需求的衛星通訊常使用之陣列天線做研究，包括利用漸進式槽縫天線搭配後端電路，其中進行單一天線輻射場型之優化，並利用不等分功率分配器達到抑制輻射場型之旁波束。二是應用於低頻量測系統接收端之0.6-2GHz雙極化漸進式槽縫天線設計。最後為設計多種尺寸之雙極化陣列天線達到超寬頻2-40GHz之應用，天線單元一樣使用漸進式槽縫天線，其模擬與實作量測有很高的一致性。

The research of antennas in this thesis can be divided into three parts. The first part is array antenna for satellite communication which is qualified high directionality and high gain. It is included Tapered Slot Antenna combined with feeding circuit. In this case we will improve the antenna’s radiation pattern, and use the unequal Wilkinson power divider to reduce the side lobe. The second part is Taper Slot Antenna with dual polarization characteristic for low frequency (0.6-2GHz) applications. The last part is the design of antenna array with dual polarization characteristic for ultra wide band (2-40GHz) applications, and the element type is also the taper slot antenna. The measured result and simulated result maintain highly consistence in this thesis.
