    • 本論文提出一款放大陣列之創新寬頻帶設計。其陣列架構採用串聯饋入形式，並於傳輸路徑中引入增益放大器及可調式相移器，俾利補償饋入網路之振幅損失及相位偏移，使系統達到可寬頻操作之目的；其組成元件包含寬頻帶二路及三路邊緣耦合器、由 Lange 耦合器所實現之可調式反射式相移器、增益放大器、以及平面準八木天線。
    將上述元件組合為寬頻帶放大陣列，經量測驗證，其實驗結果與理論值及數值模擬皆相吻合，其主波束於 50% 之比例頻寬內，可維持固定之端射輻射，故順利實現寬頻帶空間功率結合之研究目的。

    A novel wideband amplifying array with phase compensation scheme is proposed in this thesis. The array adopts a series feed network with additional gain amplifiers and tunable phase shifters for amplitude and phase compensating making the proposed arrays suitable for wideband operation. The components in this amplifying array include 2-way/3-way edge couplers, tunable phase shifters, gain amplifiers, and planar quasi-Yagi antennas.
    By a direct integration of the foregoing components, the proposed amplifying array experimentally demonstrates a wide operation bandwidth of 50 %, with the mainbeam fixed at the broadside direction. The measured antenna gains agree well with the theoretical values. This amplifying array successfully provides a wideband solution for spatial power combining.
