Abstract

The invention discloses an RFID antenna and an equipment terminal therewith. The RFID antenna comprises a linear antenna, a metal plate and a feeder line, wherein the linear antenna is wound into an S-shaped structure and is fixed above the metal plate. The first end of the linear antenna is electrically connected with the metal plate, and the second end of the linear antenna is connected with a circuit board. One end of the feeder line is electrically connected with the metal plate, and the other end of the feeder line is connected with the circuit board. The equipment terminal comprises theRFID antenna, an upper cover, a lower cover and a circuit board. According to the invention, through a specific wiring mode, the antenna standing-wave ratio is reduced, and the performance of the RFIDantenna is optimized. The technical problems that in the prior art, the reading distance is short, and the standing wave ratio is high are solved, and therefore the RFID antenna and the equipment terminal which are beneficial for increasing the reading distance and improving the recognition effect are provided.

Description

technical field [0001] The invention relates to the field of RFID, in particular to an RFID RFID antenna and a device terminal with the antenna. Background technique [0002] RFID: Radio Frequency Identification, radio frequency identification, is a communication technology that can identify specific targets and read related data through radio signals. [0003] Standing wave ratio: The ratio of the standing wave antinode voltage to the valley voltage amplitude, which is used to indicate whether the antenna and the radio wave transmitter are matched. [0004] As the field of application of RFID identification technology becomes wider and wider, more users feel the convenience and efficiency brought by RFID technology. RFID industrial tablet computers are used in many fields. In the existing technology of RFID tablet computers, an RFID identification system mainly composed of three parts: RFID antenna, reader, and electronic tag is usually used. The RFID antenna communicates...
