求翻译：RFID技术中的电磁波传播，读写器和标签二者之间通过耦合元件实现射频信号的空间（无接触）耦合，进行能量传递，数据交换。是什么意思？

RFID technology in the electromagnetic wave propagation, the RF signals to achieve the space (no contact) coupled to transfer energy, data exchange between reader and tag by a coupling element.

In the technology RFID of electromagnetic waves, readers and tags by means of the coupling between 2 components to the RF signal space (NO contact) coupling, energy transfer, and data exchange.

In the RFID technology electromagnetic wave dissemination, the reader-writer and between label the two realizes the radio-frequency signal space through the matching plug (not to have contact) the coupling, carries on the energy transfer, the data exchange.

Propagation of electromagnetic waves in RFID technology, the reader and tag RF signal coupling between the two components of the space (non-contact) coupling, energy transfer, the exchange of data.
