| How to design UHF RFID anti-metal tag antenna? |
* Answer
| The design principles of the UHF RFID anti-metal tag antenna are as follows.1.Impedance Matching of the Tag The antenna and its feed structure are adjusted to achieve conjugate matching of the antenna impedance to the chip impedance.2.Gain of the tag The advantage of UHF RFID technology is that the tag has a far read range.4.Dimensions of the label In order to meet the needs of practical applications, the area of the tag antenna is required to be as small as possible and the thickness is as thin as possible.5.The cost of the label In order to reduce the cost, on the one hand, the material of the label is required to be cheap, and on the other hand, the processing of the antenna is required to be simple. |
