Problems solved by technology

However, nothing can be perfect all at once, and there are many difficulties in the research of Chipless RFID, including how to reduce the cost of RFID to barcodes and QR codes, how to achieve a high amount of information storage under passive conditions, and how to realize self-positioning Functions, etc., while the existing Chipless RFID is basically realized by PCB technology, there are documents (Arnaud Vena, etl, "Design of Chipless RFID Tags Printed on Paper by Flexography", IEEE Transactions on Antennas and Propagation, Vol.61, No.12 , Dec.2013) reported that the metal thickness of 5 microns can be printed on paper, which is the thickest at present, but the technology in this paper is to use electroless deposition of metal copper instead of directly printing with a printer; at the same time, the literature (Rubayet-E-Azim Anee , and Nemai C.Karmakar, "Chipless RFID Tag Localization" IEEE Trans.Microw.Theory Techn., vol.61, no.11, pp.4008-4017, Nov.2013) reported the latest about Chipless RFID localization technology, But here only involves the two-dimensional positioning method of Chipless RFID

Embodiment Construction

[0031]The resonant frequency of the design label here is 4.5GHz, and the dimensions: structure (1) is 42.5mm, structure (2) is 43.5mm, structure (4) is 2.2mm, structure (5) is 21mm, structure (6) is 1mm .

[0032] Here define φ 1 is 0 degrees, φ 2 is 120 degrees, θ 3 is 240 degrees, θ 1 , θ 2 , θ 3 is 90 degrees. According to expression (1), the distance r can be calculated from the delay time. When R is determined, r 1 , r 2 and r 3 can be obtained by expression (1), and the angular position information of the tag can be obtained by expression (3).

[0033] a) When the R radius is 1 meter,

[0034] can be tested to r 1 , r 2 and r 3 They are 1.4m, 1.4m and 1.4m respectively, and θ can be obtained by estimation t is 0 degrees, φ t is X, that is, the label is located at the top point of the sphere,

[0035] when tested to r 1 , r 2 and r 3 They are 1.6m, 1.6m and 1.6m respectively, and θ can be obtained by estimation t is 30 degrees, φ t is 120 degrees,
