An antenna is a transducer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space) or vice versa. A component for transmitting or receiving electromagnetic waves in a radio device. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and the like all use electromagnetic waves to transmit information and work by depending on antennas. In addition, in transferring energy with electromagnetic waves, non-signal energy radiation also requires antennas. The antennas are generally reciprocal in that the same pair of antennas can be used as both transmit and receive antennas. The same antenna is the same as the basic characteristic parameter for transmission or reception. At present, the antenna is more and more widely applied, the anti-interference requirement is more and more strict, and the design types are diversified. Such as a radio frequency antenna used in an RFID electronic tag or label, to be widely used in the field of logistics. It can store data related to merchandise, credit cards, access cards, and vehicle control in RF. The radio frequency antenna circuit is matched with a radio frequency IC chip in the RFID electronic seal, and an RFID reader matched with the radio frequency antenna is used for reading information in the radio frequency IC chip. The RFID electronic seal can also be applied to the locking device, and when the locking device is in a locking state, the radio frequency IC chip can be read. The ideal antenna does not consider the feeding part, but in order to extract signals, the extracted point is called the feeding part, the english is expressed by feedpoint, the field distribution of the antenna is generally influenced by the addition of the feeding part, and the selection of the point is also exquisite.

When the RFID electronic tag is manufactured, the surface with the antenna and the radio frequency IC chip is directly coated with the adhesive, so that the RFID electronic tag can be attached to commodities, objects or parts for use. When the RFID reader transmits a signal to the RFID electronic tag for receiving, the radio frequency IC chip is started, the data stored in the radio frequency IC chip is transmitted to the RFID reader through the antenna for receiving, and the RFID reader can read the return signal of the RFID electronic tag. Since the application of the conventional typical RFID tag is limited by the influence of external environmental factors, for example, signals read by the RFID reader are easily interfered and diffracted in water, liquid or high humidity air, which results in a high error rate of reading signals, and if the RFID tag is attached to an object with a metal surface, the data reading error rate is high or the RFID tag cannot be read.
