Intelligent UHF RFID antenna
The entrance guard system will be used in the library management of warehousing and logistics. The functions that need to be realized are checking in and out, guarding against theft, and locating the area. The most common problem in the project is misreading. The entrance guard installation is at the door, and the shelves in the warehouse are about one meter away from the door. Usually the antenna will read the shelves. In similar projects, the antenna selected must be circularly polarized narrow-beam antenna, because the direction of the antenna is cluttered, so antenna polarization is very important, and then narrow-beam antenna, because the door management is the left and right sides of the radiation as narrow as possible, so as to ensure that it can not be misread to the warehouse inside the mark. The other advantage of the narrow-wave antenna is that the horizontal beam is narrow and the vertical beam is wide, so that the goods piled up high can be recognized normally, and the problem of Misreading and crossreading can be solved very well.
