Problems solved by technology

However, it is difficult for the general printed dipole antenna to achieve broadband conjugate matching with the RFID chip in a small size, so that in practical applications, the antenna needs to be repeatedly developed and debugged for different regions of use, which will increase product costs
[0005] The existing broadband RFID antenna design scheme is mainly based on the fractal form, which requires high processing accuracy on small-sized PCBs and is not easy to debug

Abstract

The invention relates to a broadband RFID tag printed antenna structure. Better full-band matching design is provided for bands supported by an RFID chip on a smaller PCB, and specific size can be designed according to different application environment requirements, so that the RFID tag product can be better used on surfaces of metal and non-metal. In actual use, designed parameters are flexible and are convenient to debug in practice, a single layer of PCB is adopted, so that PCB processing requirements are not high, RFID chip communication quality is ensured, further, product production costis lowered, and design reliability is ensured.

Description

technical field [0001] The invention relates to a broadband RFID label printed antenna structure, which belongs to the technical field of radio frequency transmission. Background technique [0002] In order to ensure that the cost of UHF RFID tag products can be controlled and the products can meet the reliability design requirements, the antenna is often directly connected to the RFID chip, so the impedance matching of the input port of the RFID chip is completely borne by the antenna. For passive RFID chip design, its input impedance changes with frequency, so it brings challenges to broadband antenna design. [0003] Since the implementation of communication coding, error correction and modulation methods in the passive RFID underlying protocol is relatively simple, the quality of wireless communication cannot be guaranteed. Therefore, passive RFID chips are mostly in the form of differential input and output, so as to increase the transmission rate and eliminate environm...
