Influence of the metal to RFID electronic label, so that reading away from farther.
The antenna part includes the excitation electric feedback ring being made of L shape open slot 24 with concave shape sheet metal 25, using leading
The chip 28 that electric glue is powered on inlay layer 2 and by the excitation electric feedback ring；L shape open slot 24 surrounds concave shape metal
Piece 25 is arranged, and 28 paste position of chip is aligned at the spill mouth of concave shape sheet metal 25 and is located in the long side of L shape open slot 24.
Chip 28 and antenna part may be implemented in difference in size and location by adjusting L shape open slot 24 and concave shape sheet metal 25
Conjugate impedance match on material surface, have reached optimal reading away from, substantially increase Antenna Design read away from flexibility.The present embodiment
Can also by adjust 21 length of inlay summit portion be adjust antenna part bending position come adapt to different batches material because
It is influenced caused by thickness, density tolerances, the elongated then frequency decline of the antenna length of bending, on the contrary then frequency rises, and existing skill
Frequency in art adjusts intelligence by more conversion materials or replacement antenna, and therefore, the present embodiment electronic tag is for different batches
Insulating medium layer 3 carries out being adjusted flexibly for antenna Inlay layer 2, and the performance to ensure each electronic tag produced is steady
It is fixed reliable, and read away from reaching requirement.
The side of concave shape sheet metal 25 is additionally provided with several Parallel Design gap structures 26.
The grounded part design is in inlay bottom surface portions 22 comprising surrounds shape by the hollow out groove 27 at several intervals
At rectangular area, which is used to read the coding of RFID printer.
Referring to figure 3., Fig. 3 is the read forward of ordinary antennas tag design away from measurement result figure, and overall dimensions are length
60mm, width 25mm, thickness 1.2mm, using Monza MR6P, ordinary antennas tag design pastes metal surface, solid in the region US
The highest of fixed pattern reader is read to show the reading of two ordinary antennas label away from measurement result in Fig. 3 away from being 3-3.5 meters.It please join
According to the read forward that Fig. 4-Fig. 5, Fig. 4 are the present embodiment product away from test result figure, Fig. 5 is the back read of the present embodiment product away from survey
