Abstract

The utility model discloses a be applied to RFID radio -frequency antenna of express delivery container bag classification management, including the radio -frequency antenna body, its characterized in that, by the resonant cavity line around constituting the rectangle resonant cavity, the long limit middle part of resonant cavity no. 1 chip that is provided with the breach form bind the position, the chip bind the position and be used for setting up RF chips, two radio -frequency antenna wings are extended on another long limit of resonant cavity, the radio -frequency antenna wing to both sides parallel extend then upwards be 45 degrees extend and constitute extensions, the utility model discloses can absorb peripheral more electromagnetic waves, it is very high that the radio frequency reads sensitivity, once reads the RF chips information of express delivery container bag in batches more easily, and discernment sensitivity is high, and the error score is low.

Description

A kind of RFID radio-frequency antennas for being applied to express delivery paper bag Classification Management

【Technical field】

This utility model is related to a kind of RFID radio-frequency antennas for being applied to express delivery paper bag Classification Management.

【Background technology】

In modern logistics industry, where express delivery paper bag needs circulation Classification Management, sorting, typically using engineered form Sorted.Even if the dependence radio RF recognition technology for occurring in the last few years（RFID technique）It is also to enter on a small scale to carry out sorting OK, its sorting and identification function more fall behind, and its reason is that the size of traditional RFID radio frequency boards is less, causes the reading of radio frequency board Write sensitivity relatively low so that the reading of radio frequency board is closer to the distance, and disposably read more radio frequency board and have difficulties, increased The difficulty that the vast as the open sea express delivery paper bag of logistics center is identified and sorts, causes inefficiency, or even the feelings of mistake sorting Condition, have impact on the popularization and application of REID.

【Utility model content】

Technical problem to be solved in the utility model is to overcome drawbacks described above, there is provided one kind is applied to the classification of express delivery paper bag The RFID radio-frequency antennas of management, according to the RFID radio frequency boards that shape and structure feature of the present utility model makes, radio frequency chip can be with More electromagnetic waves are absorbed, and radio frequency reads sensitivity height, distance is read than traditional radio-frequency antenna remote, it is easier to once read and criticize The radio frequency chip information of amount.

Technical solutions of the utility model are as described below：

A kind of RFID radio-frequency antennas for being applied to express delivery paper bag Classification Management, including radio-frequency antenna body, it is characterised in that By resonator cavity line around rectangle resonator cavity is constituted, the chip that described one long side middle part of resonator cavity is provided with nick shaped is tied up Positioning, described chip bonding position are used to arranging radio frequency chip, and two radio-frequency antenna wings are extended on another long side of the resonator cavity, Described radio-frequency antenna wing is extended in parallel to extend in 45 degree to both sides then up and constitutes extension, the described extension of left and right two Portion is symmetricly set in the both sides of rectangle resonator cavity, and described its initial end width of extension is 1.65 millimeters, its terminal end width For 2.9 millimeters, its total length of extension of the left and right sides is 47.5 millimeters, and width is 25.5 millimeters.

According to above-mentioned technical characteristic, the beneficial effects of the utility model are, its radio-frequency antenna it is small-sized, although only There are 25.5*47.5 millimeters, but according to architectural feature of the present utility model, radio frequency chip can absorb the more electromagnetism of periphery Ripple, radio frequency reading sensitivity are very high, read apart from farther than traditional radio-frequency antenna, it is easier to once read the express delivery of batch The radio frequency chip information of paper bag, identification sensitivity are high, and error rate is low, and the line thickness of this utility model radio-frequency antenna figure reaches 2.9 millimeters, it is easy to system to be punched the die cut versions of antenna, radio-frequency antenna, low manufacture cost, without dirt is manufactured using clicking technique Dye, is easy to spread.

【Specific embodiment】

As shown in Figure 1, 2, this utility model is applied to the RFID radio-frequency antennas of express delivery paper bag Classification Management, including radio frequency day Line body, it is characterised in that surrounded by resonator cavity line 21 and constitute rectangle resonator cavity 22, in the middle of described 22 1 long side of resonator cavity Position is provided with the chip bonding position 23 of nick shaped, and described chip bonding position 23 is used to arrange radio frequency chip, the resonator cavity Two radio-frequency antenna wings 24 are extended on 22 another long sides, and it be in then up 45 that described radio-frequency antenna wing 24 is extended in parallel to both sides Degree extends composition extension 25, and the described extension 25 of left and right two is symmetricly set in the both sides of rectangle resonator cavity, described Its initial end width of extension L1 is 1.65 millimeters, and its terminal end width L2 is 2.9 millimeters, the extension 25 of the left and right sides its Total length L 3 is 47.5 millimeters, and width L4 is 25.5 millimeters.

As shown in Fig. 3 and following table, under different read-write power, this utility model reads distance with market like product Contrast：

As shown in Fig. 4 and following table, it is that, under 20DB read-write power, this utility model is special with market like product read direction The contrast of property：

Data above illustrates that this utility model is read apart from farther than traditional radio-frequency antenna, it is easier to once reads and criticizes The radio frequency chip information of amount, this utility model are easy to system to be punched the die cut versions of antenna, manufacture radio frequency day using clicking technique Line, low manufacture cost is pollution-free, is easy to spread.
