fin antenna 中文意思是什麼

fin antenna 解釋
鰭形天線
  • fin : n 1 鰭，魚翅；鰭狀物。2 手 臂。3 【航海】（潛水艇的）鰭板，水平舵；【火箭】舵；【航空】穩定器，安...
  • antenna : n. （pl. -nae , antennas）1. 【動物；動物學】觸角。2. 【無線電】天線〈英國常用 aerial〉。
  1. The total system of linearly tapered fin - fed slot antenna, which is made up of radome, lwsa and the feed structure, was optimized by commercial software ansoft hfss

    除了線性槽天線的設計以外，饋電結構的設計對于整個天線系統來說也是很關鍵的，鰭線和波導的匹配好壞也決定了整個天線系統性能。
  2. The antenna investigated in the dissertation is the unilateral slot antenna with fed taper and end taper, which is fed by fin - line

    最後藉助於三維高頻電磁場模擬軟體ansofthfss ，對整個鰭線饋電線性漸變天線系統進行了優化。
  3. In this dissertation, the performance of linearly tapered fin - fed slot antenna ( lwsa ) is discussed in theory, simulation and experiment. the radiation pattern characteristic influenced by changes of antenna ’ s dielectric material, tapered shape and dimension is studied detailedly. though the tapered slot antenna design is very important, a good waveguide - to - finline taper transitions is also needed because they could not thought over separately

    本文主要採用理論分析、數值模擬和實驗等手段對線性漸變槽天線的特性進行了研究，分析了介質材料、天線漸變段以及天線尺寸對天線方向圖的影響，分別設計了天線罩、線性漸變槽天線以及天線的饋電結構。
  4. The antenna is obtained by extending the longitudinal strip of the fin - line, and etched on a metallized dielectric substrate. it is operating at ka band ( center frequency : 34ghz ), which has a good agreement between simulated and measured results. its e - and h - plane 3db main lobe beamwidth are 79. 25 and 80. 03 degrees respectively with sidelobes less than - 10db

    天線工作的中心頻率為34ghz ， e面和h面測試方向圖主瓣寬度分別為79 . 25o和80 . 03o ，旁瓣電平均小於- 10的db ，模擬和試驗結果基本一致，所設計天線的各項指標經測試基本達到要求。
