The purpose of this utility model is to provide a kind of sensitivity and read-write reliability preferably small size ultrahigh frequency electronic tag.
For reaching above-mentioned purpose, a kind of small size ultrahigh frequency electronic tag that the utility model provides comprises:
Circular substrate;
Radio frequency chip, is attached to the center of substrate first surface;
Antenna, be attached to substrate first surface, this antenna comprises a folded dipole and three circular arc Radiative antenna elements, folded dipole is rounded and centered by described radio frequency chip, the openend of folded dipole connects described radio frequency chip, and three circular arc Radiative antenna elements are equally spaced distributed in centered by described radio frequency chip, radius is greater than one of described folded dipole radius circumferentially;
Panel, is bonded in substrate first surface; And
Release liners, is bonded in second substrate surface.
In above-mentioned small size ultrahigh frequency electronic tag, preferably, each Radiative antenna elements by a thin arc and a thick arc in series, thick arc to be positioned at outside thin arc and the two concyclic heart, and the other end of thin arc connects folded dipole.
In above-mentioned small size ultrahigh frequency electronic tag, preferably, described folded dipole diameter 9.6mm, live width 0.4mm, described thin camber line segment length 7.6mm, wide 0.3mm, described thick camber line segment length 9.8mm, wide 0.65mm.
Owing to adopting above-mentioned antenna structure, the sensitivity of small size ultrahigh frequency electronic tag is good, and read-write reliability is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of some embodiment small size ultrahigh frequency electronic tags;
Fig. 2 is its decomposing schematic representation.
Embodiment
The utility model is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 1-2, this small size ultrahigh frequency electronic tag comprises: circular substrate 11, radio frequency chip 10, antenna, panel 41, release liners 31.
Radio frequency chip 10 is attached to the center of substrate 11 first surface.
Antenna is attached to substrate 11 first surface.This antenna comprises a folded dipole 12 and three circular arc Radiative antenna elements 13.Folded dipole 12 is rounded, and centered by described radio frequency chip 10, the openend of folded dipole 12 connects described radio frequency chip 10.Three circular arc Radiative antenna elements 13 are equally spaced distributed in centered by described radio frequency chip 10, radius is greater than one of described folded dipole 12 radius circumferentially.
Panel 41 is bonded in substrate 11 first surface by the first glue-line 22.Panel 41 preferably copper millboard.
Release liners 31 is bonded in substrate 11 second surface by the second glue-line 21.
Substrate 11 is PET (polyethylene terephthalate) substrate preferably, and PET is a kind of thermoplastic polyester, has following characteristic: folding resistance is good, has excellent choke, water, wet goods performance, insulation.
In certain embodiments, each Radiative antenna elements 13 by a thin arc 132 and a thick arc 131 in series, thick arc 131 and the concyclic heart of thin arc 132, thick arc 131 is positioned at outside thin arc 132, and the other end of thin arc 132 connects folded dipole 12.
As folded dipole 12 diameter of phi 9.6mm, live width 0.4mm, the long 7.6mm of thin arc 132, wide 0.3mm, the long 9.8mm of thick arc 131, during wide 0.65mm, small size ultrahigh frequency electronic tag has better sensitivity and read-write reliability.
Below in conjunction with specific embodiments the utility model has been done and compared detailed description; but these specific descriptions should not be construed as the restriction to the utility model protection domain, those skilled in the art can also make other modification according to explanation of the present utility model or be equal to replacement etc.Protection domain of the present utility model is as the criterion with claims.
