antenna load impedance

基本解释

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，需要用一個寬帶變負載阻抗匹配網絡來實現天線與電台之間的匹配。
Finally, the antenna, ASK modulation, power supply of the tag, load impedance modulation, demodulation, power supply sensor and HF power amplifier were realized.
本文實現了天線、ASK調制、應答器的電源、負載調制、解調、電源傳感器和高頻功放模塊。
