[0026] See also Figure 1 and Figure 2 The antenna 100 includes: a dielectric layer 10, a conductive layer 20 and a feeding component 30. The dielectric layer 10 includes a first surface (not shown) and a second surface (not shown) arranged opposite to each other. The metal layer is arranged on the first surface. The conductive layer 20 is provided with a groove 201. The groove 201 divides the metal layer to obtain a first conductive portion 202 and a second conductive portion 203. The first conductive portion 202 and the second conductive portion 203 are connected, and the radiation frequencies of the first conductive portion 202 and the second conductive portion 203 are different. The feeding component 30 is arranged on the first surface and connected to the conductive layer 20. When the antenna 100 receives an external signal, the feeding component 30 couples the signal to the conductive layer 20 and stimulates current flow. Due to the presence of the slot 201, the conductive layer 20 is divided into two parts with different electrical lengths (the first conductive part 202 and the second conductive part 203), which resonate at different frequency bands. Therefore, the antenna 100 can cover multiple frequency bands at the same time and realize multi-band communication. Figure 5 and Figure 6 , Figure 5 is a diagram of the high-frequency signal transmission rate of the antenna 100, Figure 6 : is a low-frequency signal transmission rate diagram of the antenna 100. Through the above setting, full coverage of the low-frequency band can be achieved while the high-frequency band is also fully covered. While achieving high-speed communication, the miniaturization of the antenna 100 is ensured.

[0027] In some embodiments, the dielectric layer 10 has a size of 7*35 [mm]^2, and the metal layer 20 is disposed on the dielectric layer 10 to further achieve the purpose of miniaturization.

[0028] In the embodiment of the present application, antenna 100 utilizes a design that combines an FPC (flexible printed circuit) or PCB (printed circuit board) with a cable. This not only miniaturizes antenna 100 but also improves antenna 100 efficiency through sophisticated branch design. This design allows antenna 100 to maintain high performance while being easily integrated into various compact devices, such as smartphones, tablets, routers, and small base stations.

[0029] See also Figure 3 The first conductive portion 202 includes a first rectangular radiating portion 221, a first slot portion 222 and a fourth rectangular radiating portion 225. The first rectangular radiating portion 221 is extended with a second rectangular radiating portion 223 and a third rectangular radiating portion 224. The first slot portion 222 is arranged between the second rectangular radiating portion 223 and the third rectangular radiating portion 224. The first slot portion 222 is arranged between the second rectangular radiating portion 223 and the third rectangular radiating portion 224. The current distribution is changed by introducing the first slot portion 222, thereby affecting the radiation characteristics of the antenna 100. The third rectangular radiating portion 224 is connected to the second conductive portion 203, ensuring the electrical continuity between the first conductive portion 202 and the second conductive portion 203, while also allowing them to resonate independently at different frequency bands. The fifth rectangular radiating portion 231 is respectively extended with a second radiating branch 232 and a sixth rectangular radiating portion 233. The second radiating branch 232 and the first radiating branch 227 are bent and connected, and the second radiating branch 232 and the first radiating branch 227 are arranged in parallel. The sixth rectangular radiating portion 233 and the fourth rectangular radiating portion 225 are arranged opposite to each other. When the antenna 100 is working, the radio frequency signal is coupled to the conductive layer 20 through the feeding component 30, and current is stimulated to flow. The distribution of current on the conductive layer 20 is affected by structures such as the slot 201, the radiating portion and the radiating branch, thereby forming a specific radiation pattern. By adjusting the size, shape and position of the conductive layer 20 structure, the radiation characteristics of the antenna 100 can be precisely controlled to meet the needs of multi-band communication. In the present application embodiment, the first conductive portion 202 and the slot 201 cooperate to transmit low-frequency signals in the range of 2.4 GHz to 2.5 GHz and high-frequency signals in the range of 5.15 GHz to 5.85 GHz. This not only enables high-speed communication for the antenna 100, but also enables multi-band signal transmission while achieving miniaturization. Specifically, the first rectangular radiating portion 221 and the first slot 222 cooperate to transmit low-frequency signals in the range of 2.4 GHz to 2.5 GHz, while the fourth rectangular radiating portion 225 and the L-shaped slot 226 cooperate to transmit high-frequency signals in the range of 5.15 GHz to 5.85 GHz.

The second conductive portion 203 and the slot 201 cooperate with each other to transmit a low-frequency signal of 2.4GHZ-2.5GHZ and a high-frequency signal of 5.95-7.125GHZ. Specifically, the fifth rectangular radiating portion 231 and the slot 201 cooperate to transmit a high-frequency signal of 5.95-7.125GHZ, and the sixth rectangular radiating portion 233 and the T-shaped slot 234 cooperate to transmit a low-frequency signal of 2.4GHZ-2.5GHZ.

[0031] See also Figure 4 The antenna 100 further includes an ink protective layer (not shown), which is coated on the conductive layer 20. The ink protective layer can further protect the conductive layer 20 from oxidation, thereby extending the service life of the antenna 100. The conductive layer 20 is provided with a grounding point (not shown) and a feeding point (not shown). One end of the feeding component 30 is connected to the grounding point and the feeding point respectively, and the other end of the feeding component 30 is used to connect with the electronic component. Specifically, the feeding component 30 includes a feeding cable 301, a grounding pad 302 and a feeding The electric pad 303 and the ground pad 302 are arranged at the feeding point. The ground pad 302 is arranged at the grounding point. One end of the feeding cable 301 is connected to the ground pad 302 and the feeding pad 303 respectively. The other end of the feeding cable 301 is used to connect to the electronic component. The main function of the ground pad 302 is to provide a stable reference potential to ensure that the antenna 100 can work properly. The feeding pad 303 is responsible for coupling the RF signal in the feeding cable 301 to the conductive layer 20 of the antenna 100 and stimulating the flow of current. The size, shape and position of the feeding pad 303 also need to be carefully designed to ensure a good connection with the feeding cable 301 and efficient signal transmission. When the electronic component generates an RF signal, the signal is transmitted to the feeding pad 303 through the feeding cable 301 and coupled to the conductive layer 20 of the antenna 100. The current on the conductive layer 20 generates radiation under the excitation of the RF signal, forming an electromagnetic wave that propagates to the surrounding space. At the same time, the ground pad 302 provides a stable reference potential for the antenna 100 to ensure that the antenna 100 can operate normally.

The dielectric layer 10 includes a first surface and a second surface arranged opposite to each other. The metal layer is arranged on the first surface.
