dc.description.abstract | 本論文提出了一種由片狀天線構成的低旁波瓣位準(side lobe level, SLL)電氣式可導向被動陣列輻射體(electrically steerable passive array radiator, ESPAR),其沿H平面與E平面兩方向皆適合擺放。它可以更進一步被用來排列成2維ESPAR。被動輻射體以來自主動輻射體的耦合為饋入,其導向角控制由調整被動輻射體的可變電抗負載達成。我們指出並解決了一些設計ESPAR時遇到的重要議題,包含輻射元件的間隔、有意義的陣列因數(array factor, AF)正規化、SLL縮減,並詳細討論其他設計考量。本貼片天線ESPAR最後以可變電容作為可變電抗附載實作,再進行分析結果、全波模擬結果、量測結果之間的比較。 | zh_TW |
dc.description.abstract | A patch electrically steerable passive array radiator (ESPAR) suitable for arranging along both H-plane and E-plane with low side lobe level (SLL) is proposed. It could be further used to form a 2D ESPAR. The steering angle is controlled by adjusting the variable reactive loads of the passive elements, which take the coupling from the active element for feeding. We indicated and solved some important issues encountered while designing the patch ESPAR, including the spacing between radiating elements, mean-ingful normalization of the array factor (AF), and SLL reduction of the ESPAR. Other design considerations are also discussed in detail. The patch ESPAR is eventually im-plemented with the varactor diodes as the variable reactive loads. Comparisons among analyzed results, full-wave simulated results, and measured results, are given. | en |
