[0031] Example 1

[0032] In some embodiments, please refer to the accompanying Figures 1-5 drawings of the specification. A small-sized full-band intelligent tag includes a chip antenna conductive pattern module 1 disposed on a first carrier insulating layer and an antenna conductive pattern module 2 disposed on a second carrier insulating layer, and the first carrier insulating layer and the second carrier insulating layer are compounded into one body;

[0033] The chip antenna conductive pattern module 1 includes a first point slot 11, a second point slot 12, a third point slot 13, and a chip antenna conductive pattern body 14. The first point slot 11, the second point slot 12, and the third point slot 13 are sequentially formed inside the chip antenna conductive pattern body 14 from top to bottom. The first point slot 11 is located at the lower end of the feeding port 4, and the lower ends of the left and right sides of the upper side of the chip antenna conductive pattern body 14 extend into the first point slot 11 to form protrusions. The lower end of the second point slot 12 extends into the third point slot 13 to form a protrusion. The slot widths of the first point slot 11, the second point slot 12, and the third point slot 13 are equal. The slot depth of the second point slot 12 is less than the slot depth of the first point slot 11, and the slot depth of the first point slot 11 is less than the slot depth of the third point slot 13;

[0034] In this article, the slot width refers to the distance between the left and right ends, and the slot depth refers to the distance between the upper and lower ends.

[0035] The first carrier insulating layer is made of PET film, and the second carrier insulating layer is made of PET film or paper or fabric substrate; the chip antenna conductive pattern is formed by laser cutting or etching process, and the antenna conductive pattern is formed by die-cutting process.

[0036] The length of the chip antenna conductive pattern body 14 is 12 mm, that is, the distance between the left and right sides of the chip antenna conductive pattern body 14, and the width is 15.5 mm, that is, the distance between the upper and lower sides of the chip antenna conductive pattern body 14.

[0037] A central U-shaped antenna slot 3 is provided in the middle of the antenna conductive pattern module 2, and the chip antenna conductive pattern body 14 is located in the central U-shaped antenna slot 3.

[0038] The chip antenna conductive pattern body 14 is in a closed shape.

[0039] The lower end of the chip antenna conductive pattern body 14 extends outward and protrudes to form an antenna composite epitaxial edge 15. At the same time, the bottom of the central U-shaped antenna groove 3 that is composite with the antenna composite epitaxial edge 15 extends into the groove towards the inside of the groove. The antenna composite epitaxial edge 15 and the bottom of the central U-shaped antenna groove 3 are composite into one body. The composite area of the antenna composite epitaxial edge 15 and the bottom of the central U-shaped antenna groove 3 is not greater than 1 / 2 of the area of the antenna composite epitaxial edge 15.
