impedance match of antenna 中文意思是什麼
impedance match of antenna
解釋
天線阻抗匹配-
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。 -
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。
