Definitions
- the invention relates to radio engineering and is intended for radio frequency identification of textile products (linen, clothing, ammunition, etc.).
- Radio frequency tags are a multilayer structure. A prerequisite for the operation of these tags is the presence of an auxiliary substrate on which an external antenna is located in a specific configuration.
- the near-field RFID tag must be centered and fixed in relation to an external antenna that is sewn or attached to an auxiliary substrate. In this case, the near-field radio frequency tag should be in close proximity to the external antenna for reliable induction coupling, otherwise the tag is not suitable for a large reading distance.
- the disadvantage of this solution is the unreliability during repeated washing, a narrow frequency band and the bulkiness of the structure. When washing multiple times, the induction coupling is broken, because the proximity of the radio frequency label of the near radius relative to the external antenna is violated, and a certain configuration of the external antenna makes the label narrow-band, tuned to a certain frequency range.
- radio frequency tag consisting of a printed circuit board with a chip for radio frequency identification and an external antenna in the form of springs [4], [5].
- This design is unsuitable for the identification of textiles due to design flaws. Disadvantages: rigidity and brittleness springs when exposed to alternating voltage, the absence of a sealing case, a narrow frequency band, large dimensions.
- Radio frequency tags currently used to identify textiles do not meet the requirements of reliability, secrecy and minimization, have large dimensions, and in some cases have a narrow frequency range.
- Achievable technical result when using the claimed invention is to increase the reliability, versatility with respect to RF identification systems of different frequency ranges, increase the radiation power and read distance, as well as minimize the size and increase the secrecy of the RF tag.
- an additional flexible polymer coating can be used in places where the antenna exits from the sealed enclosure.
- This polymer may be made of heat shrink material.
- FIG. 1-5 show the options labels for radio-frequency identification of textile products with the following notation:
- the RFID tag consists of a two-layer printed circuit board (3) with vias.
- an identification microcircuit is soldered or welded on a printed circuit board (1), which can be made in the form of a separate chip or in the form of a housing with microcircuit pins.
- an extension inductor (2) is soldered to the printed circuit board.
- the extension inductor can be made in the form of an electronic component for surface mounting.
- a flexible metal cable (5) is soldered or welded, which consists of intertwined between themselves metal threads.
- the cable may be coated with polymeric material (6) to increase reliability.
- the polymer case (7) can be made of a heat-resistant polymer with high strength and resistance to repeated alternating loads, high pressure resistance, including at high temperature, high chemical resistance, resistance to alkali, salts and organic solvents.
- the exit points of the antenna from the sealed polymer case can be protected from fracture by an additional elastic polymer coating (8), which can be made of heat-shrinkable material.
- FIG. 1 is a cross-sectional view of an RF tag.
- FIG. 2 shows a particular case of a radio-frequency tag in cross section with a polymer coating (6) on the antenna (5).
- FIG. Figure 3 shows a particular case of a radio-frequency tag in a section with an additional elastic polymer coating (8) at the points where the antenna exits the sealed polymer case.
- FIG. 4 shows a general view of an RF tag.
- Label for radio-frequency identification of textile products works as follows.
- an interested party for example, a company that launches laundry, inserts a radio frequency identification mark in the seam of each textile product.
- the antenna provides a signal from the reader and the reverse transmission of individual information contained in the identification chip.
