Abstract

The utility model discloses a be applied to RFID radio -frequency antenna of suitcase 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 extend to both sides and be " U " type and constitute the extension, two " U " type extension symmetries of the left and right sides set up in the both sides of rectangle resonant cavity, its initial end width of " U " type extension be 1.6 millimeters, its terminal width is 2.85 millimeters, the utility model discloses RF chips can absorb peripheral more electromagnetic waves, and it is very high that the radio frequency reads sensitivity, and is more farther than traditional radio -frequency antenna reads the distance, once reads radio frequency identification tablet chip information in batches more easily.

Description

A kind of RFID radio-frequency antennas for being applied to luggage case Classification Management

【Technical field】

This utility model is related to a kind of RFID radio-frequency antennas for being applied to luggage case Classification Management.

【Background technology】

Where airport, railway station, bus station etc. need to carry out different luggage case sortings, typically entered using engineered form Row sorting.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 whole luggage cases are identified and sort, causes inefficiency, or even the situation of mistake sorting, have impact on RF identification The popularization and application of technology.

【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 luggage case classification pipe The RFID radio-frequency antennas of reason, according to the RFID RF identification boards that shape and structure feature of the present utility model makes, radio frequency chip can To absorb more electromagnetic waves, radio frequency reads sensitivity height, reads distance than traditional radio-frequency antenna remote, it is easier to once read The RF identification board chip information of batch.

Technical solutions of the utility model are as described below：

A kind of RFID radio-frequency antennas for being applied to luggage case Classification Management, including radio-frequency antenna body, it is characterised in that by Around rectangle resonator cavity is constituted, described one long side middle part of resonator cavity is provided with the chip bonding of nick shaped to resonator cavity line Position, described chip bonding position are used to arranging radio frequency chip, and two radio-frequency antenna wings, institute are extended in another long side of the resonator cavity The radio-frequency antenna wing stated extends to both sides and is in that " U " type constitutes extension, and described " U " type extension of left and right two is symmetrical arranged In the both sides of rectangle resonator cavity, described its initial end width of " U " type extension is 1.6 millimeters, and its terminal end width is 2.85 Millimeter, its total length of " U " type extension of the left and right sides is 48 millimeters, and width is 26.5 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 26.5*48 millimeters, but according to architectural feature of the present utility model, radio frequency chip can absorb the more electromagnetic waves of periphery, Radio frequency reading sensitivity is very high, reads apart from farther than traditional radio-frequency antenna, it is easier to which the radio frequency for once reading batch is known Other board chip information, identification sensitivity are high, and error rate is low, and the line thickness of this utility model radio-frequency antenna figure is up to 2.85 millis Rice, is easy to system to be punched the die cut versions of antenna, manufactures radio-frequency antenna using clicking technique, and low manufacture cost is pollution-free, is easy to Spread.

【Specific embodiment】

As shown in Figure 1, 2, this utility model is applied to the RFID radio-frequency antennas of luggage case Classification Management, including radio-frequency antenna Body, it is characterised in that surrounded by resonator cavity line 11 and constitute rectangle resonator cavity 12, described 12 1 long side pars intermedia of resonator cavity Position is provided with the chip bonding position 13 of nick shaped, and described chip bonding position 13 is used to arrange radio frequency chip, the resonator cavity 12 Two radio-frequency antenna wings 14 are extended on another long side, and described radio-frequency antenna wing extends to both sides and is in that " U " type constitutes extension, Described " U " type extension of left and right two is symmetricly set in the both sides of rectangle resonator cavity 12, and described " U " type extension is at the beginning of which L1 width in top is 1.6 millimeters, and its end L2 width is 2.85 millimeters, " U " type extension its total length of the left and right sides L3 is 48 millimeters, and width L4 is 26.5 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 RF identification board chip information of amount, this utility model are easy to system to be punched the die cut versions of antenna, are manufactured using clicking technique Radio-frequency antenna, low manufacture cost is pollution-free, is easy to spread.
