    • 本論文提出一創新雙天線整合雙模態相位陣列系統。此系統在饋入網路不引入主動元件之前提下，使相位陣列於低頻帶操作為信號回溯陣列，而高頻帶則為波束切換陣列。若與前人所提出之數款整合相位陣列系統比較，有效簡化異質整合多模態相位陣列系統之饋入網路電路面積，有利於未來實現整合於可攜式無線通訊系統之目標。
    為實現該雙模態相位陣列系統，本論文先提出具創新效能之雙模態複合式左右手合成傳輸線。該合成傳輸線以傳輸線、線電感、表面黏著電容所組成。若與文獻中常見的複合式左右手傳輸線相比較，此傳輸線最大之不同，乃在於特徵阻抗可依操作頻帶之不同而獨立設計，並以此獨特電路特性實現異質整合雙模態陣列之操作。
    本論文將複合式合成傳輸線進行整合，成功實現雙天線整合陣列餽入電路之核心元件：雙模態分合波器。將此分和波器與其它輔助元件如：天線、雙工器、增益放大器及環路器等進行整合設計，即完成此雙模態雙天線相位陣列系統。經電路與輻射場型之實驗量測，吾人充分驗證其信號回溯與波束切換之功能。
    本論文詳盡討論此創新系統架構之設計概念、電路佈局，及模擬與量測結果，並進行適當分析討論。

    Without the need of active switches, in this thesis, a two elements integrated retrodirective/beam-switching phased array is developed and verified. The feeding network is equivalent to a reflection-type retrodirective array in the lower band, but automatically turns into a beam-switching array in the upper band. The proposed system features a reduced architecture but still functions as a dual-operational mode heterogeneous integrated phased array.
    The key component for successfully integrating the unique phased array, namely the dual-mode coupler, is introduced. This essential component is realized by composite right/left-handed (CRLH) synthesized transmission lines consisting of traditional microstrip lines and artificial left-handed lines. Compared with conventional CRLH lines, the characteristic impedance of the proposed one can be independently designed at different operation frequencies.
    By integrating the core building blocks and a number of auxiliary commercial components, the dual-model two-element phased array system is realized and experimentally demonstrated. Measured circuit responses and radiation characteristics of the proposed array are introduced through experiments to validate this unique concept.
