    摘要: 本論文主要研製可應用於無線光纖(wireless-over-fiber)通信系統發射器之天線陣列。在天線陣列設計方面選用準八木宇田天線(Quasi Yagi-Uda antenna)為單一天線,具有結構簡單、體積小、饋入方便之優點,且其為高增益、高指向性之單端輻射(end-fire)場型。由於以全波電磁模擬軟體作天線陣列分析與單一天線相比,模擬軟體須計算原單一天線數倍尺寸之結構,因此需耗費更多分析時間以及更高的硬體需求。基於上述原因,本論文研發之陣列程式可解析陣列天線設計中各參數調整,其包括振幅、相位、個數及間距,對於本論文之高增益陣列天線與陣列波束掃描之設計可以節省分析時間,最後設計結果會與全波模擬軟體(Ansoft HFSS)做比較,並探討誤差原因與改善方法。此外,將光子發射器中之天線陣列與近彈道單載子光檢測器(near-ballistic uni-travelling-carrier photodiode, NBUTC-PD)整合於單一晶片,為有效驗證上述發射器,該電路將設計於90GHz至110GHz,並就由量測作為驗證。此電路使用半導體製程方法實現,相信此架構可在寬頻無線光纖通信應用中扮演重要角色。 In this thesis, the design and analysis of the quasi Yagi-Uda element-based antenna array employed as the  transmitting antenna of the integrated photonic transmitters are presented. The quasi Yagi-Uda element antenna used as the single element has the advantages of simple in configuration, compact in size, convenient to feed-in, and reasonably directional radiation. However, the analysis of entire antenna array structure with the full-wave electromagnetic simulator is time-consuming, which renders the array implementation impractical. Here, the array radiation characteristics obtained with the radiation patterns of sorely a single-element full-wave is proposed. For experimental demonstration, the antenna array is integrated with the near-ballistic uni-travelling-carrier photodiode to form an integrated photonic transmitter, which operates at the W-band (75-110 GHz). The radiation from the transmitter with the proposed quasi Yagi-Uda array is measured and compared to the simulated results for verification.
