[0024] Reference Figure 1The first embodiment of the present application provides an antenna assembly for a POS machine, which comprises: an FPC board 1, an antenna layer 2, a feeding point 3, and a feeding point 4; the antenna layer 2 is laid on the FPC board 1, and the antenna layer 2 is provided with a first slot 21 and a second slot 22; the first slot 21 and the second slot 22 are arranged without intersecting each other; the feeding point 3 and the feeding point 4 are arranged separately and are both coated on the antenna layer 2; the first slot 21 is located between the feeding point 3 and the feeding point 4, and the second slot 22 is located at the periphery between the feeding point 3 and the feeding point 4; the feeding point 3 is coupled to the feeding point 4 through the first slot 21 to couple out a first frequency band, and the feeding point 3 is coupled to the feeding point 4 through the second slot 22 to couple out a second frequency band.

[0025] In the embodiment, the FPC board 1 serves as a basic carrier of the antenna assembly for the POS machine, and provides stable support and electrical connection for the antenna layer 2. The antenna layer 2 is coated or attached on the FPC board 1. The feeding point 3 and the feeding point 4 are both coated or attached on the antenna layer 2, and the materials of the feeding point 3 and the feeding point 4 are the same as that of the antenna layer 2, which is electrolytic copper. The feeding point 3 is an energy input point when the antenna receives or transmits signals, and the feeding point 4 is a grounding point of the antenna, which is used to provide a stable reference potential.

[0026] Specifically, the first frequency band is coupled out through the feeding point 3, the feeding point 4, and the first slot 21 on the antenna layer 2. By adjusting the length of the slot body of the first slot 21, the first frequency band can be tuned to resonate at 2400Mhz-2500Mhz, which is the working frequency of the 2.4G antenna and the Bluetooth antenna. The second frequency band is coupled out through the feeding point 3, the feeding point 4, and the second slot 22 on the antenna layer 2. By adjusting the length of the slot body of the second slot 22, the second frequency band can be tuned to resonate at 5150Mhz-5850Mhz, which is the working frequency of the 5G antenna.

[0027] In summary, the antenna assembly for the POS machine can realize the working frequencies of the 2.4G antenna, the Bluetooth antenna, and the 5G antenna. Moreover, the antenna assembly for the POS machine adopts one feeding point 3, one feeding point 4, and the slot of the antenna layer 2, which not only cancels the parasitic antenna, but also realizes simple antenna wiring, reduces the antenna area, and reduces the cost.

[0028] Reference Figure 1 One side of the antenna layer 2 extends to form a radiation arm 5, and the feeding point 3 is coupled to the feeding point 4 through the first slot 21 to couple out a third frequency band.

[0029] In the embodiment, the third frequency band is coupled out through the feeding point 3, the feeding point 4 and the radiation arm 5. The feeding point 3 is connected with current. The current flows through the radiation arm 5 and then flows to the feeding point 4. Energy is radiated in the form of electromagnetic wave, thereby generating the resonance of the GPS. The feeding point 3 is connected with current. The current flows through the first slot 21 and then flows to the feeding point 4, thereby generating the resonance of the first frequency band. The feeding point 3 is connected with current. The current flows through the second slot 22 and then flows to the feeding point 4, thereby generating the resonance of the second frequency band.

[0030] Specifically, the current is alternating current. The current flowing from the feeding point 3 to the feeding point 4 on the third frequency band is the minimum, which is less than the current flowing from the feeding point 3 to the feeding point 4 on the second frequency band and the first frequency band. The resonance of the GPS is 1575.42Mhz.

[0031] With reference to Figure 1 , the first slot 21 comprises a first slot body 211 and a second slot body 212.

The second slot body 212 is arranged without intersecting with the second slot 22.

[0032] In the embodiment, the first slot body 211 and the second slot body 212 make the first frequency band coupled out through the feeding point 3, the feeding point 4 and the first slot 21 on the antenna layer 2 be the IFA antenna, thereby making the anti-interference ability of the antenna assembly for the POS machine be stronger than that of the monopole antenna.

[0033] Specifically, the monopole antenna is an antenna with only the feeding point 3.

[0034] With reference to Figure 1 , the extension length of the second slot body 212 is greater than the extension length of the second slot 22.

[0035] In the embodiment, the first slot 21 makes the resonance tuned out of the first frequency band be greater than the resonance tuned out of the second frequency band by the second slot 22.

[0036] With reference to Figure 1 , the radiation arm 5 comprises a first radiation section 51 and a second radiation section 52. One end of the first radiation section 51 is connected with a side of the antenna layer 2. One end of the second radiation section 52 is perpendicularly connected with the other end of the first radiation section 51.

[0037] In the embodiment, the feeding point 3 receives signals, which are transmitted to the antenna layer 2 first, then to the first radiating section 51 connected with the antenna layer 2, and then to the second radiating section 52. The second radiating section 52 is used to optimize the radiation pattern of the antenna of the third frequency band, so that the antenna of the third frequency band can more effectively transmit and receive signals in a specific direction or angle.

[0038] With reference to Figure 1 , a plurality of first through holes 11 are arranged on the FPC plate 1, and a plurality of second through holes 23 are arranged on the antenna layer 2 in a one-to-one correspondence, and the first through holes 11 and the second through holes 23 are coaxially communicated to be arranged for mounting nails.

[0039] In the embodiment, the first through hole 11 and the second through hole 23 are used to fix the FPC plate 1 with the antenna layer 2 in the accessory of the POS machine.

[0040] With reference to Figure 1 , the length range L2 of the feeding point 3 is 1.2mm-1.7mm, and the length range L2 of the feeding point 4 is 1.2mm-1.7mm.

[0041] With reference to Figure 1 , the width H2 of the feeding point 3 is 2mm±0.3mm, and the width H2 of the feeding point 4 is 2mm±0.3mm.

[0042] With reference to Figure 1 , the length L1 of the FPC plate 1 is 37.85mm±0.2mm, and the width H1 of the FPC plate 1 is 23.02mm±0.2mm.
