求翻譯:反向散射耦合是采用反射電磁波能量的方式完成通信的。電子標簽平時處于匹配狀態,它從讀寫器發射來的電磁場中獲取能量和信息。而當電子標簽發送數據時,微控器根據數據的不同改變RFID電子標簽電線的負載電阻值,從而改變天線的散射面積。這樣就會使讀寫器天線接受到的電磁波能量隨數據的變化而變化,最終完成電子標簽與讀寫器的通信。是什么意思?![]() ![]() 反向散射耦合是采用反射電磁波能量的方式完成通信的。電子標簽平時處于匹配狀態,它從讀寫器發射來的電磁場中獲取能量和信息。而當電子標簽發送數據時,微控器根據數據的不同改變RFID電子標簽電線的負載電阻值,從而改變天線的散射面積。這樣就會使讀寫器天線接受到的電磁波能量隨數據的變化而變化,最終完成電子標簽與讀寫器的通信。

Backscatter coupling is the use of reflective manner of electromagnetic energy to communicate. Usually in a tag match state, launch it from the reader's electromagnetic field to get energy and information. When the electronic tag to send data, microcontroller based on the data wires of different RFI
