Description

A kind of RFID radio-frequency antenna being applied to drop for clothing and books and periodicals

[technical field]

The utility model relates to a kind of RFID radio-frequency antenna being applied to drop for clothing and books and periodicals.

[background technology]

The size of traditional RFID radio frequency drop for clothing or the RFID radio frequency board that is applied to books and periodicals is less, cause the read-write sensitivity of radio frequency drop lower, drop is made to read close together, and the more radio frequency drop of disposable reading has difficulties, increase clothes storage or library collection flat bag statistics time used, have impact on the efficiency of full storage statistics.

[utility model content]

Technical problem to be solved in the utility model overcomes above-mentioned defect, a kind of RFID radio-frequency antenna being applied to drop for clothing and books and periodicals is provided, according to the RFID radio frequency drop that shape and structure feature of the present utility model makes, radio frequency chip absorbs more electromagnetic wave, radio frequency reads highly sensitive, read distance than the radio-frequency antenna of traditional same area, more easily once read the radio frequency drop chip information of batch.

Technical solutions of the utility model are as described below:

A kind of RFID radio-frequency antenna being applied to drop for clothing and books and periodicals, comprise radio-frequency antenna body, it is characterized in that, by resonant cavity line around forming rectangle resonant cavity, described middle part, resonant cavity one long limit is provided with the chip bonding position of nick shaped, two radio-frequency antenna wings are extended on another long limit of described resonant cavity, described radio-frequency antenna wing extends to both sides and is that " S " type forms extension, described its initial end width of " S " type extension is 1.5 millimeters, its terminal end width is 2.75 millimeters, its length of " S " type extension of the described left and right sides is 45 millimeters, width is 24 millimeters.

According to above-mentioned technical characteristic, the beneficial effects of the utility model are, its radio-frequency antenna small-sized, although only have 24*45 millimeter, but according to architectural feature of the present utility model, radio frequency chip can absorb more electromagnetic wave, it is very high that radio frequency reads sensitivity, read apart from farther than the radio-frequency antenna of traditional same area, more easily once read the radio frequency drop chip information of batch, the line thickness of the utility model radio-frequency antenna figure reaches 2.75 millimeters, be convenient to the die cut versions of the die-cut antenna of system, clicking technique is adopted to manufacture radio-frequency antenna, cost of manufacture is low, pollution-free, be convenient to spread.

[accompanying drawing explanation]

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the utility model technical parameter schematic diagram in Fig. 1.

Fig. 3 is under different read-write power, and the utility model and market like product read the comparison diagram of distance.

Fig. 4 is under 20DB reads and writes power, the comparison diagram of the utility model and market like product read direction characteristic.

In the drawings: 1, resonant cavity line; 2, resonant cavity; 3, chip bonding position; 4, radio-frequency antenna wing.

[embodiment]

As shown in Figure 1, 2, the utility model by resonant cavity line 1 around forming rectangle resonant cavity 2, described middle part, resonant cavity 2 one long limit is provided with the chip bonding position 3 of nick shaped, two radio-frequency antenna wings 4 are extended on another long limit of described resonant cavity 2, described radio-frequency antenna wing 4 extends to both sides and is that " S " type forms extension, described its initial end width of " S " type extension L1 is 1.5 millimeters, its terminal end width L2 is 2.75 millimeters, its length L3 of " S " type extension of the described left and right sides is 45 millimeters, and width L4 is 24 millimeters.

As shown in Fig. 3 and following table, under different read-write power, the utility model and market like product read the contrast of distance:

As shown in Fig. 4 and following table, under reading and writing power at 20DB, the contrast of the utility model and market like product read direction characteristic:

Above data explanation, the utility model reads apart from farther than traditional radio-frequency antenna, more easily once read the radio frequency drop chip information of batch, the utility model is convenient to the die cut versions of the die-cut antenna of system, clicking technique is adopted to manufacture radio-frequency antenna, cost of manufacture is low, pollution-free, is convenient to spread.
