![]() ![]() The more overture the antennas have, the less detection distance. The angle of opening depends on the area to be covered, for example: 70 °, 100 °, etc. Overcast angle and gain: Using antennas with gains of between 8.5-10 dbi or more, will allow us to emit more power and obtain a higher reading ratio. NF (Near Field) antennas are used to read RFID tags within a few centimeters. Linear polarization antennas are used when the orientation of the tags is known and controlled and is always the same. The antennas create different wave fields and cover different distances.Īntenna Type: Circular polarization antennas work best in environments where the orientation of the tag varies. When an RFID chip crosses the antenna field, it is activated and emits a signal. RFID Antennas are responsible for emitting and receiving waves that allow us to detect RFID chips. In this article I will define with a brief explanation each of the main elements when implementing an RFID project. Gen2 UHF RFID systems consist of: readers, antennas, printers, and RFID tags or labels. The typical reading range is 0-12 meters. The reader processes the data so that we can integrate them into our application and give them meaning. They do not need batteries and can be used for many years. The waves "give energy" to the tags so that they can communicate by emitting a unique ID. This is a rich proposal for UHF RFID Label tags.The RFID reader emits radio waves of specific frequencies through RFID antennas. The range of standard products combines high quality with competitive prices, thanks to economies of scale in our production. Our RFID UHF antenna designs vary in size and performance, and they cover most needs for RFID projects that require dry inlay, wet inlay, or RFID tags/stickers.
