Problems solved by technology

Due to the design of the antenna, the existing electronic tags can only be read in one direction, which not only has dead angles, but also has low efficiency
In addition, the chip fixation of the existing electronic tags is not stable enough

Embodiment 1

[0027] Example 1 (best example):

[0028] refer to figure 1 As shown, the electronic tag of the preferred embodiment 1 has a substrate 1 on which an antenna 2 is disposed, and a chip (not shown in the figure) is further disposed on the substrate 1 , and the chip is electrically connected to the antenna 2 . The antenna 2 is composed of a peripheral outer ring part, a middle short-circuit ring part, and an axis part connecting the outer ring part and the short-circuit ring part. Wherein, the outer ring part is surrounded by 4 curve segments located on the left and right of the horizontal axis and located on the upper and lower parts of the longitudinal axis to form an open ring with 4 gaps. They are the "L"-shaped curve segment 7 on the left of the horizontal axis, the "L"-shaped curve segment 8 on the right of the horizontal axis, the "L"-shaped curve segment 4 on the upper part of the vertical axis, and the "L"-shaped curve segment on the lower part of the vertical axis 3,...

Embodiment 1

[0029] The "L" type curve segment 7, the "L" type curve segment 8, the serpentine line segment 9, the serpentine line segment 10, the 1 / 4 arc segment 11, the 1 / 4 arc segment 12, The 1 / 4 arc segment 13 and the 1 / 4 arc segment 14 constitute the antenna on the horizontal plane, the L"-shaped curve segment 3, the L"-shaped curve segment 4, the serpentine line segment 5, and the serpentine line segment 6, 1 The / 4 arc segment 11 , the 1 / 4 arc segment 12 , the 1 / 4 arc segment 13 , and the 1 / 4 arc segment 14 constitute the vertical plane antenna. Since the circular short-circuit rings of the 1 / 4 circular arc segments 11, 12, 13, 14 are used in common for the two antennas, it is a key point in antenna design. When adjusting the antenna in the horizontal direction, we can first adjust the short-circuit ring part in the middle. If the frequency is still high, adjust the serpentine line segments 9 and 10, and the "L"-shaped curve segments 7 and 8 play the role of fine-tuning. Similarly,...

Embodiment 2

[0031] refer to figure 2As shown, the second embodiment is also an antenna pattern of different routings that is changed based on the above-mentioned antenna design principle. Specifically: the electronic tag has a substrate 1', an antenna 2' is provided on the substrate 1', and a chip (not shown in the figure) is also provided on the substrate 1', and the chip is electrically connected to the antenna 2'. The antenna 2' is composed of a peripheral outer ring part, a middle short-circuit ring part, and an axis part connecting the outer ring part and the short-circuit ring part. Among them, the outer ring part is formed by four 1 / 4 arc segments 3', 4', 7', 8' located on the left and right of the horizontal axis and on the upper and lower parts of the longitudinal axis to form four gaps A1, Unclosed circles of A2, A3, A4. The short-circuit ring part is composed of a closed rhombus, including 4 straight line segments 11', 12', 13', 14'. The axis part is respectively composed o...

Abstract

The invention relates to an electronic identification tag which is provided with a substrate. An antenna and a chip are arranged on the substrate, and the chip is electrically connected with the antenna. The antenna consists of an outer ring unit on the periphery, a short circuit ring unit in the middle and an axis unit connecting the outer ring unit with the short circuit ring unit. The outer ring unit is a non-closed ring which is formed by four curved segments in an encircling manner and provided with four notches. The short circuit ring unit consists of a closed curved line. One ends of four segments of the axis unit are respectively connected to the corresponding four curved segments of the outer ring unit, the four segments are all connected to the closed curved line of the short circuit ring unit and extend to be close to the center of the short circuit ring unit to form four antenna connecting points, and the four antenna connecting points are electrically connected with four interfaces of the chip. The electronic identification tag is used for fields of logistics and supply management, production, manufacturing and assembly, access control, electronic tickets, automatic road toll and the like.

Description

technical field [0001] The invention relates to an electronic label, and belongs to G06K19 / 077 in the IPC classification number. Background technique [0002] Electronic tags, realized through RFID (Radio Frequency IDentification) technology, are a communication technology that can identify specific targets and read and write related data through radio signals without the need to establish mechanical or optical contact between the identification system and specific targets. It is widely used In logistics and supply management, manufacturing and assembly, airline baggage handling, animal identification, access control, electronic tickets, automatic road toll collection and other fields. [0003] The structure of the electronic tag generally includes a substrate on which an antenna is provided. The antenna is generally formed by etching a metal layer or metal paste and attached to the substrate. At the same time, there is basically an RFID chip. The corresponding interface of ...
