[0041] The substrate 11 may be made of an insulating dielectric material, such as FR-4 glass fiber board, ceramic substrate, etc.

[0042] The first radiation portion 12 is connected to the second radiation portion 13 , and the first radiation portion 12 and the second radiation portion 13 jointly excite a first radiation frequency band.

[0043] It can be understood that in one embodiment, the first radiation portion 12 and the second radiation portion 13 can jointly excite the 2.4 GHz frequency band (frequency range 2.412-2.484 GHz), that is, the first radiation frequency band can be the 2.4 GHz frequency band.

However, the frequency band of the antenna structure used in electronic devices in the prior art can only cover the frequency band range of 4.915GHz to 5.825GHz. Therefore, the antenna structure 100 of the present application can increase the frequency band range, thereby greatly improving the wireless transmission capability and increasing the transmission speed.

[0055] Please also read Figures 1 to 4 The antenna structure 100 further includes a first feeding point a and a second feeding point b. The first feeding point a is connected to the second radiating portion 13, and the first feeding point a is used to feed a current signal to the second radiating portion 13, so that the first radiating portion 12 and the second radiating portion 13 jointly excite the first radiation frequency band.

In other words, the metal power line 16 is a metal flat cable in the electronic device 200 that is itself configured to provide power signals and / or communication signals to the non-RF module 230, and there is no need to add it separately, thereby saving the cost and space occupied by the antenna structure 100. The metal power line 16 can include multiple connecting wires, and the multiple connecting wires are used to transmit power signals and communication signals to the non-RF module 230 respectively.

[0060] For example, the metal power line 16 can be used to provide a power signal and / or a communication signal to a camera module in the electronic device 200 so that the camera module can operate.

[0061] Specifically, Figure 3 As shown, the metal power line 16 may include a first connection portion 160, a second connection portion 161 and a third connection portion 162. One end of the first connection portion 160 is connected to the control mainboard of the electronic device 200 to provide a power signal and / or a communication signal to the metal cable.

The side of the third connection portion 162 away from the metal grounding portion 15 is connected to the camera module to transmit the power signal and / or communication signal provided by the control mainboard to the camera module.

[0062] In the embodiment of the present application, the shapes of the substrate 11 and the metal grounding portion 15 can be adapted to the shapes of the second radiating portion 13 and the antenna module 14. Figures 1 to 3As shown, the substrate 11 may be formed with a first side 110 , a second side 111 , a third side 112 , a fourth side 113 , a fifth side 114 and a sixth side 115 . Among them, the first side 110 is arranged away from the first radiation portion 12 and parallel to the first radiation portion 12, one end of the first side 110 is connected to one end of the second side 111, the other end of the second side 111 extends in a direction close to the first radiation portion 12 and is connected to one end of the third side 112, the third side 112 is arranged parallel to the first side 110 and the first radiation portion 12, and the other end of the third side 112 is connected to the fourth side 113, the other end of the fourth side 113 extends in a direction away from the first radiation portion 12 and is connected to one end of the fifth side 114, the other end of the fifth side 114 extends in a direction close to the second side 111 and is perpendicularly connected to one end of the sixth side 115, and the fifth side 114 is arranged parallel to the first side 110, the other end of the sixth side 115 extends in a direction away from the first radiation portion 12 and is connected to the other end of the first side 110, and the sixth side 115 is arranged parallel to the second side 111. The connection between the first side 110 and the second side 111 forms an arc, the connection between the second side 111 and the third side 112 forms an arc, and the fourth side 113 is semicircular and convex in a direction away from the first radiation portion 12 .

[0063] The metal grounding portion 15 may be substantially rectangular and disposed on the second side 111 of the substrate 11 , and a notch is formed in the metal grounding portion 15 near the fifth portion 144 of the antenna module 14 so that part of the fifth portion 144 is accommodated in the notch.

[0064] The first feeding point a, the second feeding point b and the second grounding point d can be arranged side by side and spaced apart on the first edge 110 of the substrate 11, the first part 140 of the antenna module 14 and the first section 130 of the second radiating portion 13 can be arranged parallel to the second edge 111 and the sixth edge 115, and the first section 130 of the second radiating portion 13 is arranged on the sixth edge 115, the second section 131 of the second radiating portion 13 is arranged on the fifth edge 114 and parallel to the fifth edge 114, and the third section 132 of the second radiating portion 13 is arranged on the fourth edge 113.

[0065] See also Figure 5 , Figure 5 The graph is a graph showing the relationship between the standing wave ratio and frequency of the wireless signal excited by the antenna module 14 and the metal power line 16 in the antenna structure 100 of the embodiment of the present application as the preset distance changes. The preset distance changes from 0.2 mm to 0.5 mm. Figure 5 It can be seen that Figure 5The horizontal axis is the frequency of the wireless signal excited by the antenna module 14 and the metal power line 16, and the vertical axis is the voltage standing wave ratio (VSWR). The minimum value of the standing wave ratio is 1. The smaller the standing wave ratio is, the smaller the reflection loss of the antenna module 14 and the metal power line 16 is. When the standing wave ratio is 1, it means that the reflection loss is zero, and the wireless signal excited by the antenna module 14 and the metal power line 16 is 1. Figure 5 It can be seen that when the preset distance is 0.4 mm, the frequency range of the wireless signal excited by the antenna module 14 and the metal power line 16 is 5.925-7.125 GHz, that is, the third radiation frequency band is the 6 GHz band. It can be seen that when the preset distance is 0.4 mm, the bandwidth of the third radiation frequency band excited by the antenna structure 100 is the widest.

[0066] Of course, in the embodiment of the present application, the antenna structure 100 is not limited to the above frequency bands. Specifically, the shape, length and / or width of the antenna structure 100 can be adjusted according to the required frequency. That is, the working frequency band of the antenna structure 100 can be achieved by adjusting its shape, length and / or width parameters according to specific needs.

Therefore, there is no need to additionally set up an antenna module 14 that radiates multiple frequency bands. The antenna structure 100 can also excite multiple radiation frequency bands, thereby effectively improving the bandwidth of the antenna structure 100, saving space for the electronic device 200, improving the space utilization of the electronic device 200, and realizing the arrangement of an antenna structure 100 with a wider bandwidth in a limited space.
