[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] As described in the background art, metal components in electronic devices or metal casings of electronic devices may affect the signal transmission and reception of antennas in the electronic devices.

[0022] In order to solve the above technical problems, the present application proposes an antenna that reduces the influence of metal on signals. A closed shielding member is set around the antenna body, and the shielding member can shield the signals affected by metal around the antenna to prevent them from entering the antenna, thereby ensuring the stability of the signal received by the antenna and the transmission rate.

[0023] The antenna and electronic device provided in the embodiments of the present application are described below with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, the antenna disclosed in the embodiment of the present application includes an antenna body 100 and a shielding member 200. The shielding member 200 is closed and surrounds a closed area 210 in the shielding member 200. The shielding member 200 also includes a coupling component 220 and a grounding feed point 230. One end of the antenna body 100 is coupled to the coupling component 220. The shielding member 200 can be grounded through the grounding feed point 230, so that the antenna body 100 coupled to it through the coupling component 220 can also be grounded. The antenna body 100 can be arranged in the closed area 210, and the thickness of the antenna body can not exceed the thickness of the shielding member 200, so that the front, rear, left and right sides of the antenna body are surrounded by the shielding member, while the upper and lower surfaces are exposed, so that the antenna body can receive signals entering from the top or bottom, but the signals affected by metal entering from other directions are all shielded. When the antenna body is arranged in an electronic device, the signal can enter from the non-metallic shell of the antenna body and reach the antenna body, and the signals affected by the metal elements are all shielded by the shielding member.

[0025] By coupling the antenna body 100 with the coupling component 220 , the antenna body 100 can couple high and low frequency signals, so that the waveform signal of the antenna can be stable and meet the signal transmission conditions.

[0026] A feeding point 110, i.e., a signal feeding point, is provided on the antenna body 100. The feeding point 110 may be provided at the other end of the antenna body 100 relative to the coupling component, and the distance from the end point of the end point is within a preset value range. The distance from the feeding point 110 to the end point may not exceed one third of the total length of the antenna and may not be less than one fifth. Preferably, the distance from the feeding point 110 to the end point may be one fourth of the total length of the antenna.

[0027] The antenna body 100 is a WIFI antenna and can be a monopole antenna. Specifically, the antenna body 100 can be an antenna that implements the WIFI 6E frequency band and can cover the frequency bands of 2400-2500 MHz, 5100-5850 MHz, and 5925-7125 MHz.

[0028] The shielding member 200 may be made of a metal material. The shape of the shielding member 200 may be determined according to the shape of the accommodation space for accommodating the antenna in the electronic device, so that the shielding member 200 may be disposed in the accommodation space of the electronic device and the closed space 210 formed by the shielding member 200 may accommodate the antenna body 100, and the shielding member 200 may not come into contact with the antenna body 100.

[0029] The embodiment of the present application also provides an electronic device, in which the antenna can be arranged in the main body of the electronic device. The electronic device can be a laptop computer or any other device that needs to use a WIFI antenna, such as a mobile terminal such as a mobile phone.

[0030] When the electronic device is a laptop computer, Figure 3 As shown, the main body portion 300 may be the lower half of the notebook computer, and the main body portion may include a top cover, a bottom cover and a bracket.

[0031] The bracket can be arranged in the storage space between the top cover and the bottom cover, and the bracket is provided with a first storage space and a second storage space. The first storage space can be used to set the first antenna, and the second storage space can be used to set the second antenna. Specifically, the first antenna can be as follows Figure 1 The second antenna may be as shown. Figure 2 Antenna shown.

[0032] The first antenna and the second antenna may have completely the same or symmetrical shapes, and the shapes of the shielding members of the first antenna and the second antenna may also be determined according to the shapes of the first accommodation space and the second accommodation space, respectively. The shape of the first accommodation space may be adapted to the shape of the shielding member of the first antenna, and the shape of the second accommodation space may be adapted to the shape of the shielding member of the second antenna.

[0033] The first accommodation space may be disposed on the first side 310 , and the second accommodation space may be disposed on the second side 320 .

[0034] When used, the electronic device can control the first antenna and the second antenna respectively, so that the first antenna and the second antenna can send and receive signals simultaneously or individually.

[0035] The first antenna and the second antenna can cover all WIFI 6E frequency bands at the same time, or the first antenna and the second antenna can respectively cover all or part of the WIFI 6E frequency bands and make it possible to transmit and receive signals covering all WIFI 6E frequency bands when the first antenna and the second antenna transmit and receive signals together.

[0036] The first antenna and the second antenna may be respectively arranged on corresponding back plates, and the back plates may be parallel to the top cover or the angle between the back plates and the top cover does not exceed a preset threshold, for example, 5 degrees.

[0037] The top cover of the electronic device may be made of a non-metallic material, and the bottom cover may be made of a metal material. For example, the top cover may be made of plastic. The signal of the antenna may enter the electronic device through the non-metallic top cover and eventually reach the antenna. When the electronic device is a laptop computer, the top cover may be located on the side where the keyboard of the laptop computer is located, and the bottom cover may be located on the side opposite to the side where the keyboard is located.

[0038] Table 1 shows the average gain and radiation efficiency of the conventional routing of the WIFI antenna at different frequencies when the laptop is in the open state Open Model and the closed state Close Model. Table 2 shows the average gain and radiation efficiency of the first antenna Main Antenna and the second antenna AUX Antenna disclosed in the embodiment of the present application at different frequencies when the laptop is in the open state Open Model and the closed state Close Model.

[0039] Based on Table 1 and Table 2, it can be seen that the antenna disclosed in the embodiment of the present application has better signal stability and transmission effect than the conventional WIFI antenna, and can still perform stable signal transmission and reception operations in an environment containing metal components and metal casings.
