crossed antenna 中文意思是什麼

crossed antenna 解釋
交叉天線
  • crossed : adj. 十字的，裝成十字的；交叉的；劃線的（支票）；注銷的，劃十字勾銷掉的；受到阻礙的（愛情、野心等）。
  • 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 antenna design is based on using capacitive loads and slits on two crossed narrow patches with via fed - through feed system, which can reduce the size of the antenna, improve the isolation between two ports and keep considerable bandwidth respectively

    通過電容性加載減小整個天線的尺寸，通過在天線上開槽來增加天線埠之間的隔離度，採用viafed - through的饋電方式。
  2. According to the particularity of the hfsw oht by ship, we have done research on a special electrically small antenna, crossed - field - antenna ( cfa )

    由於高頻地波艦載超視距雷達對天線有小型化、適裝性等各方面的特殊要求，我們對新型電小天線?交叉場天線cfa （ crossedfieldantenna ）進行研究。
  3. Over - the - horizon radar ’ s beam - frequency is high frequency band and its wavelength is so long that the annate ’ s characters are very complicated when applicated on the ship. the character of coupling between cells and the environment must be measured to compensate in the radar signal process step. the ship - based over - the - horizon radar uses cfa ( crossed field antenna ) as array antennas ’ cell

    艦載超視距雷達使用高頻信號作為發射頻率，其波長較長，在艦船有限的空間內，陣列天線的陣元之間的耦合與陣元與背景之間耦合都十分嚴重，必須測量陣列天線通道的幅相一致性，作為雷達信號處理的補償參數。
