Radio Frequency (RF) is an abbreviation for Radio Frequency, which refers to an electromagnetic Frequency that can radiate into space, ranging from 300KHz to 300 GHz. The short term Radio Frequency (RF) is radio frequency current, which is a short term for high frequency Alternating Current (AC) variable electromagnetic wave. Alternating current that changes less than 1000 times per second is called low frequency current, and alternating current that changes more than 10000 times per second is called high frequency current, and radio frequency is such a high frequency current.

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 manufacturing the RFID tag used 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 then 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. 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.

On one hand, the metal layer shields the influence of external signals on the circuit board antenna 10, on the other hand, electromagnetic waves emitted by the antenna hit the metal layer, and the metal layer can reflect part of the electromagnetic waves, so that the electromagnetic wave strength of the antenna is enhanced, and the capability of the antenna for emitting wireless signals is improved, namely, the gain is improved. The thickness of the radio frequency antenna plate 10 of any value between 0.1mm and 100mm can ensure that the ultrahigh frequency RFID antenna and the high frequency RFID antenna can read, for example, in a 2.6mm design, the interference between the ultrahigh frequency RFID antenna and the high frequency RFID antenna is small.
