antenna load impedance

基本解釋

Proper impedance load can reduce RCS effectively, meanwhile antenna's gain and radiation efficiency are not affected.
適儅的阻抗加載能有傚降低天線RCS，同時(shí)還能保証天線的輻射性能。
The impedance matching network of changeable load and wide-belt is required because the input impedance of spiral antenna changes with frequency.
由於該天線的輸入阻抗隨頻率而變化，需要用一個(gè)寬帶變負(fù)載阻抗匹配網(wǎng)絡(luò)來(lái)實(shí)現(xiàn)天線與電臺(tái)之間的匹配。
Finally, the antenna, ASK modulation, power supply of the tag, load impedance modulation, demodulation, power supply sensor and HF power amplifier were realized.
本文實(shí)現(xiàn)了天線、ASK調(diào)制、應(yīng)答器的電源、負(fù)載調(diào)制、解調(diào)、電源傳感器和高頻功放模塊。
