antenna constant 解釋
天線常數
  • antenna : n. (pl. -nae , antennas)1. 【動物;動物學】觸角。2. 【無線電】天線〈英國常用 aerial〉。
  • constant : adj 1 恆定不變的,固定的,穩定的,恆久的;繼續不斷的。2 不屈不撓的,堅韌的。3 忠實的,有節操的。n...
  1. A model of the capsulated antenna is presented and simulations are conducted according to different numerical values of parameters involving capsulation dimensions and dielectric constant

    建立了帶有圓柱形介質封裝的天線模型,針對介質厚度、內徑和介電常數三個封裝參數的不同取值組合進行了大量模擬。
  2. So it holds a ideal ability to anti - interference and has 2 scalar level resolution in location and measuring velocity than traditional radio induction technology. and the channel composed of the new radio induction system for communication is different from the parameter - constant channel and the traditional parameter - changing channel, its parameter is decided by the mutual induction between its antenna and induction - cable, by the location of its antenna, by the signal frequency passing through, its parameter has nothing to do with the time parameter. the channel composed of the new radio induction system is a new parameter - changing channel independently of time for communication

    而且,由新型無線感應系統組成的通道既不是恆參通道,也不是一般目前所知的變參通道,其通道傳遞函數的幅值只與信號的頻率有關,與系統中天線和感應電纜之間的互感和天線的位置有關,而與時間無關,其通道傳遞函數的相位只與天線的位置有關,而與時間無關,由新型無線感應系統組成的通道是一種不隨時間變化的新型變參通道。
  3. The way of widening the band is realized by employing the inverted parasitic patch and the thick and low dielectric constant substance. with this treatment, the relative band of the antenna can be widened up to 20 %. and by adopting the way of two h - slots arranged in a “ t ” configuration, the isolation is improved

    微帶天線的頻帶展寬通過採用倒懸寄生貼片和較厚的低介電常數的介質來實現,經過這樣處理后的天線帶寬可以達到20 %以上;而隔離度的改善則是採用了兩個h形縫隙排列成「 t 」型結構。
  4.
