Embodiment 1

[0043] 1. Preparation of silver halide emulsion and samples

[0044] The emulsion was prepared according to the production method of the silver halide emulsion used in the silver salt photographic photosensitive material. The composition of the silver halide emulsion is a silver bromoiodide emulsion with 98 mol% silver bromide and 2% mol% silver iodide. The average particle size of the emulsion is 0.09 microns, and the emulsion is doped with K 2 IrCl 6 and K 3 RhBr 6 . The emulsion was further chemically sensitized to sulfur and gold with potassium tetrachloroaurate and sodium thiosulfate. Then it was evenly coated on the PET film, the coated silver amount was 4.2 g / m2, and the corresponding samples were made after drying.

[0045] 2. Exposure and development

[0046] The samples prepared by the above method are first exposed with ultraviolet light or visible light, and the exposure mask is a template containing two groups of parallel lines, wherein the line width and s...

[0060] 1. Silver halide emulsion and sample preparation

[0061] The emulsion was prepared according to the production method of the silver halide emulsion used in the silver salt photographic photosensitive material. The composition of the silver halide emulsion is a silver chlorobromide emulsion in which silver chloride is 70 mole percent and silver bromide is 30 mole percent. The average particle size of the emulsion is 0.23 microns, and the emulsion is doped with K 2 IrCl 6 and K 3 RhBr 6 . The emulsion was further chemically sensitized to sulfur and gold with potassium tetrachloroaurate and sodium thiosulfate. Then it was evenly coated on the paper base, the coated silver amount was 3.0 g / m2, and the corresponding samples were made after drying.

Abstract

The invention relates to a radio frequency identification E-tag antenna and a preparation method thereof. The antenna comprises a support body and a conductive antenna pattern formed on the support body, the surface of the conductive antenna pattern is composed of metallic silver and a copper layer covered on the metallic silver. The quality of the copper occupies 35 percent to 95 percent of the total metal quality, while the square resistance value is more than 0 and smaller than 1 Omega/ Square. The antenna acquired by the invention is of low square resistance and good conductivity, while the preparation method is of simple process, high wiring precision, being suitable for industrialized production, lower cost and being able to flexibly match with different kinds of E-tags.

Description

technical field [0001] The invention relates to an electronic tag antenna, in particular to an electronic tag antenna for radio frequency identification. Background technique [0002] Radio Frequency Identification (RFID) technology originated from the identification friend or foe system in the Second World War. It began to be used in the 1970s and began to be used on a large scale in the 1990s. It is a non-contact automatic identification based on the principle of radio frequency. technology. RFID technology takes wireless communication technology and large-scale integrated circuit technology as the core, and uses radio frequency signals and their spatial coupling and transmission characteristics to drive electronic tag circuits to transmit their stored unique codes, which can automatically identify stationary or moving targets, and efficiently Obtaining target information data, and further combining with Internet technology can also realize target tracking and information...
