In this embodiment, the projection of the second radiation surface 130b on the screen 200 falls within the projection range of the spacer 220 on the screen 200, so that the spacer 220 better separates the screen 200 from the antenna radiator 100, and further reduces the influence of the signal on the screen 200 on the electromagnetic wave signal radiated by the antenna radiator 100.

Referring to fig. 1, 2 and 9 together, fig. 9 is a schematic cross-sectional view of an electronic device along the line I-I according to a fourth embodiment of the present application. In this embodiment, the screen 200 includes a first surface 200a, a second surface 200b and a third surface 200c, the first surface 200a is a surface of the screen 200 facing the antenna radiator 100, the second surface 200b is opposite to the third surface 200c, and the second surface 200b is a display surface of the screen 200. The antenna radiator 100 includes a first end 110 and a second end 120 that are disposed opposite to each other, where the first end 110 is provided with a feeding portion, and the feeding portion is configured to receive the excitation signal. The electronic device 1 further includes a supporting board 300, the supporting board 300 is disposed adjacent to the second end 120, the supporting board 300 is disposed adjacent to the third surface 200c, and is used for supporting the screen 200, the supporting board 300 forms a reference ground of the antenna radiator 100, and the supporting board 300 is connected to the spacer 220 through a side surface.

The excitation signal received by the feeding portion is transmitted from the first end 110 of the antenna radiator 100 to the second end 120 of the antenna radiator 100, and is coupled to the reference ground through the second end 120 of the antenna radiator 100, and the excitation signal oscillates on a path formed by the first end 110, the second end 120, and the reference ground to form an electromagnetic wave signal, and the electromagnetic wave signal is radiated through the clearance area.

In the present embodiment, the supporting board 300 in the electronic device 1 is electrically connected to the spacer 220 through the side surface, so that the spacer 220 can also be used as a partial reference ground while the spacer 220 isolates the influence of the signal on the screen 200 on the electromagnetic wave signal radiated by the antenna radiator 100. For convenience of description, when the excitation signal received by the feeding portion is transmitted on the antenna radiator 100 and coupled to the isolator 220, a path of the excitation signal transmitted on the antenna radiator 100 is referred to as a first path; assuming that the excitation signal received by the feeding portion is transmitted on the antenna radiator 100 without the spacer 220 and coupled to the reference ground formed by the support board 300, a path of the excitation signal transmitted on the antenna radiator 100 is referred to as a second path. Since the supporting plate 300 is connected to the spacer 220 through a side surface, a distance between the spacer 220 and the feeding portion is greater than a distance between the feeding portion and the supporting plate 300, that is, a distance between the reference ground and the feeding portion is increased, so that an effect of an electromagnetic wave signal radiated by the antenna radiator 100 is improved, and communication quality of the electronic device 1 is improved. Further, since the support plate 300 is connected to the spacer 220 by a side surface, a distance between the spacer 220 and the feeding portion is greater than a distance between the feeding portion and the support plate 300, and thus, a length of the first path is greater than a length of the second path. It can be seen that, by connecting the support plate 300 to the spacer 220 through the side surface, the transmission path of the excitation signal on the antenna radiator 100 is lengthened, so that the excitation signal is transmitted more uniformly on the antenna radiator 100, and thus, the bandwidth of the electromagnetic wave signal radiated by the antenna radiator 100 is increased. Furthermore, since the transmission path of the excitation signal on the antenna radiator 100 is lengthened, more excitation signals are prevented from being coupled to the reference ground, and the conversion efficiency of the excitation signal into the electromagnetic wave signal is improved.

Referring to fig. 1, 2 and 10 together, fig. 10 is a schematic cross-sectional view of an electronic device along the line I-I according to a fifth embodiment of the present application. In this embodiment, the antenna radiator 100 includes a radiation body 130 and an extension portion 140, the extension portion 140 protrudes from the radiation body 130, the extension portion 140 is provided with a feeding portion, the feeding portion is used for receiving the excitation signal, and a gap area is formed among the extension portion 140, the radiation body 130 and the screen 200, and the gap area constitutes at least a part of a clearance area. In one embodiment, the feeding portion and the extending portion 140 are two separate components, and the feeding portion is disposed on the extending portion 140. It is understood that at least a portion of the other extension 140 may also serve as the feeding portion. The extension 140 protrudes from the radiation body 130, so that the structural strength of the antenna radiator 100 can be increased.

Further, the radiation body 130 includes a first sub-radiation surface 130a, a second sub-radiation surface 130b and a third sub-radiation surface 130 c. The first sub radiation surface 130a is a surface of the radiation body 130 facing the screen 200, the second sub radiation surface 130b and the third sub radiation surface 130c are disposed opposite to each other, the second sub radiation surface 130b and the third sub radiation surface 130c intersect with the first sub radiation surface 130a, and the second sub radiation surface 130b is disposed adjacent to the screen 200 compared to the third sub radiation surface 130 c. The extension portion 140 includes a first extension surface 140a and a second extension surface 140b, the first extension surface 140a and the second extension surface 140b are disposed opposite to each other, the first extension surface 140a intersects with the first sub radiation surface 130a, the first extension surface 140a is disposed adjacent to the third radiation surface 130c compared to the second extension surface 140b, and the first extension surface 140a is flush with the third radiation surface 130 c.

In the present embodiment, the first extending surface 140a is disposed flush with the third radiating surface 130c, so that when the thickness of the extending portion 140 (the distance between the first extending surface 140a and the second extending surface 140 b) is constant, and when the position of the reference ground is constant compared to the position of the antenna radiator 100, the distance between the extending portion 140 and the reference ground is increased, and therefore, the effect of the electromagnetic wave signal radiated by the antenna radiator 100 is improved, and the communication quality of the electronic device 1 is improved. Further, since the first extending surface 140a is flush with the third radiating surface 130c, a path for transmitting the excitation signal received by the feeding portion on the antenna radiator 100 is increased, so that the excitation signal is transmitted more uniformly on the antenna radiator 100, and thus, a bandwidth of the electromagnetic wave signal radiated by the antenna radiator 100 is increased. Furthermore, since the transmission path of the excitation signal on the antenna radiator 100 is lengthened, more excitation signals are prevented from being coupled to the reference ground, and the conversion efficiency of the excitation signal into the electromagnetic wave signal is improved.

In this embodiment, the extension portion 140 further includes a third extension surface 140c, the third extension surface 140c intersects with the first extension surface 140a and the second extension surface 140b, the third extension surface 140c is connected to the radiator body through the first extension surface 140a and the second extension surface 140b, and the power feeding portion is disposed on the third extension surface 140 c.

At this time, the electronic device 1 further includes a conductive sheet 700, where the conductive sheet 700 includes a conductive body 710 and a plurality of first branches 720 arranged at intervals, and a first gap 730 is formed between two adjacent first branches 720. In the present embodiment, the power feeding portion (labeled as 150) includes a power feeding body 151 and a plurality of second branches 152 arranged at intervals.
