An antenna is a converter 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 is matched with a radio frequency IC chip in the RFID electronic seal, and the RFID reader matched with the radio frequency antenna reads information in the radio frequency IC chip. The RFID electronic seal can also be applied to the locking device 100, and when the locking device 100 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 manufacturing the RFID tag in the market, a plastic sheet is prepared, an antenna and a circuit for receiving and transmitting signals are manufactured on the plastic sheet, and a radio frequency IC chip is attached to the circuit of the plastic sheet, and a pin of the radio frequency IC chip is electrically connected to the antenna. 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.

The circuit is a conductive loop consisting of a metal wire and electrical and electronic components, and is called a circuit. When the circuit is connected, the circuit can work by generating current, the circuit can work by an external power supply, and the circuit can work by generating current by an RFID technology. Different circuit functions can be realized according to different communicated electronic elements. A continuously connected segment of the circuit has two access points between which all the electronic components are connected. The access point of the circuit is a point capable of communicating with the circuit, the access point is attached to a physical mechanical component, the component may be a conductive sheet, a conductive block or a conductive plate, or may be an end of a wire, the conductive sheet, the conductive block, the conductive plate and the exposed part of the wire form a conductive area (also referred to as a conductive cell), the conductive area is composed of numerous conductive contacts, any one of the conductive contacts can be communicated with the corresponding circuit, and when there is current in the circuit, the circuit can perform corresponding work. The electrical connection in the utility model means that the access point mechanical structure of the circuit directly touches to make the circuit connected.
