Embodiment Construction

[0038] The invention relates to an identification tag, especially a radio frequency identification tag. A preferred embodiment is listed below to illustrate the present invention, but those skilled in the art know that this is only an example, not intended to limit the invention itself. The content of this preferred embodiment is described in detail as follows.

[0039] see figure 2 , figure 2 It is a functional block diagram of the three-dimensional radio frequency identification tag of the present invention. The radio frequency identification tag 300 of the present invention is used to receive the driving signal S1 and transmit the identification signal S2 to the radio frequency identification reader 100 according to the driving signal S1. The radio frequency identification tag 300 includes a transceiving identification module 31 and a resonant reflector 32 . Wherein, the driving signal S1 may be sent by an electronic device such as a radio frequency identification read...

Abstract

The invention relates to a radio-frequency identification (RFID) tag used for receiving a driving signal and sending an identification signal to a RFID reader by a reflected signal according to the driving signal. The radio-frequency tag comprises a transceiver identification module and a resonance reflector, wherein the transceiver identification module comprises a RFID chip and a transceiver antenna electrically connected with the RFID chip, and the transceiver antenna is used for receiving the driving signal and reflecting the identification signal; and the resonance reflector is electrically coupled to the transceiver identification module and is provided with a resonant cavity to enable the driving signal and the identification signal to resonate in the resonant cavity, thereby improving the signal intensity of the driving signal and the identification signal.

Description

technical field [0001] The invention relates to an identification tag, especially a radio frequency identification tag. Background technique [0002] Radio Frequency Identification (RFID) technology, commonly known as electronic tags and radio frequency identification, is a communication technology that uses radio signals to identify specific targets and read and write related data. The advantage of RFID technology is that it does not need to use A specific target can be identified by mechanical or optical contact. [0003] The structure of RFID can be divided into two parts, one is the RFID reader and the other is the RFID tag. The RFID reader is used to transmit the electromagnetic wave signal to the RFID tag, and when the RFID tag receives the electromagnetic wave signal, it will reflect an identification signal back to the RFID reader for its identification. [0004] RFID tags are divided into three categories according to whether or not a power supply is prepared insi...
