impedance match of antenna 中文意思是什麼

impedance match of antenna 解釋
天線阻抗匹配
  • impedance : n. 【物理學】阻抗。 acoustic impedance聲阻抗。
  • match : n (一根)火柴;〈古語〉(從前大炮發火用的)火繩,導火線。 light [strike] a match 擦火柴。 a safe...
  • of : OF =Old French 古法語。
  • 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 impedance match must be extremely good because at the frequency that the antenna beam ~ vork on the broad - side position, the reflcctions from all the bends add in phase to produce a large input vswr. in addition, a poor design of thc bends leads to high - power breakdown

    慢波線中使用了大量的波導e面180彎頭,系統對其駐波特性提出極高的要求,文中用高頻模擬軟體( hfss )優化設計了波導e面180彎頭。
  2. Then, lump loading is used to enhance the valid height of the antennas, as a result the input impedance of the monopole antenna undergoes gently variation with frequency, and consequently it is easy to match by wideband matching network

    加載后,輸入阻抗變化得到減緩,這是能夠使用寬帶匹配網路進行寬帶匹配的前提,經過寬帶匹配達到了天線小型化和寬帶化的設計目的。
