[0059] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the embodiments in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0060] It is obvious to those skilled in the art that various modifications and changes can be made in the present application without departing from the spirit or scope of the present application. Therefore, the present application is intended to cover modifications and changes of the present application that fall within the scope of the corresponding claims (technical solutions for protection) and their equivalents. It should be noted that the implementation methods provided in the embodiments of the present application can be combined with each other without contradiction.

[0061] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0062] As described in the background technology section, the metal housing may block or even shield the radiation of the antenna signal in the electronic device, thus affecting the antenna performance of the electronic device.

[0063] Since metal casings can block or even shield the radiation of antenna signals in electronic devices, antennas in electronic devices need to be developed with the goals of small space, high performance, high stability, low cost, and no destructive impact on the appearance of the electronic device.

[0064] In order to improve the appearance of the electronic device, the performance of the antenna, and to keep the antenna away from the noise on the motherboard of the electronic device, so that the antenna system in the electronic device has better performance, and the electronic device has a better ID and can adapt to new scenarios such as dual screens, the inventors found that a T-shaped slot antenna can be used on the appearance of the electronic device, thereby relying on the two open branches of the T-shaped slot to generate resonance and radiate the antenna signal to the outside of the electronic device. However, this method requires a larger window to be set on the D shell of the electronic device as the ground for the antenna to improve the performance of the antenna. Specifically, the width on the D shell can reach 3.5mm, which is wide and needs to be filled with insulating plastic, which is not conducive to the design of the electronic device ID and will increase the cost of the electronic device.

[0065] In view of this, an embodiment of the present application provides an electronic device, such as Figure 1 As shown, the electronic device includes:

[0066] The metal shell 10 comprises a first shell 11 and a second shell 12 connected at their edges, wherein the first shell 11 and the second shell 12 are located in different planes, and optionally, the second shell 12 is located at a side of the electronic device;

[0067] The slot antenna comprises a plurality of radiation slots 20 provided in the first shell 11 and the second shell 12. The radiation signal of the slot antenna is transmitted through the plurality of radiation slots 20 to realize outward radiation of the antenna signal in the electronic device.

[0068] It should be noted that, in this embodiment, Figure 1 As shown, the multiple radiation slots 20 are interconnected to form multiple resonant loops, thereby realizing the transmission of antenna radiation signals of multiple frequency bands.

[0069] Optionally, in one embodiment of the present application, the multiple radiation slots may include 3 radiation slots, or may include four radiation slots, or may include more radiation slots; the multiple radiation slots can form at least 4 resonant circuits. Specifically, the multiple radiation slots can form 4 resonant circuits, or may form more resonant circuits. The present application does not limit this, and it depends on the specific circumstances.

[0070] In the electronic device provided in the embodiment of the present application, the slot antenna includes a plurality of radiation slots arranged on a first shell and a second shell of a metal shell, so that the radiation signal of the slot antenna can be transmitted through the plurality of radiation slots, thereby solving the problem that the metal shell isolates or even shields the radiation signal, and improving the antenna performance of the electronic device. Moreover, in the electronic device provided in the embodiment of the present application, the plurality of radiation slots are interconnected to form a plurality of resonant circuits, so that the electronic device can realize the transmission of radiation signals of multiple frequency bands.

[0071] In addition, in the electronic device provided in the embodiment of the present application, the slot antenna includes a plurality of radiation slots arranged in the first shell and the second shell, and the first shell and the second shell are located in different planes, so that the optimal directions of the field patterns of the radiation signals transmitted outward through the radiation slots located on the first shell and the radiation slots located on the second shell are different, and then through the combination of the field pattern of the radiation signal transmitted outward through the radiation slots located on the first shell and the field pattern of the radiation signal transmitted outward through the radiation slots located on the second shell, the field pattern of the signal radiated outward by the electronic device is optimized, forming a more uniform radiation field pattern, thereby improving the antenna performance of the electronic device.

[0072] Optionally, in one embodiment of the present application, Figure 2 As shown, the slot antenna includes a first radiation slot 21 and a second radiation slot 22 arranged on the first shell 11, and a third radiation slot 23 arranged on the second shell 12, so that the slot antenna has multiple radiation slots formed by the first radiation slot 21, the second radiation slot 22 arranged on the first shell 11 and the third radiation slot 23 arranged on the second shell 12.

[0073] Taking the electronic device as a laptop computer as an example, based on the above embodiments, in one embodiment of the present application, the first shell is the C shell or D shell of the electronic device, and the second shell is at least a portion of the side shell (side wall) connected to the edge of the first shell.

[0074] In another embodiment of the present application, continue as Figure 1 As shown, the slot antenna includes a third radiation slot 23 arranged on the first shell 11, and a first radiation slot 21 and a second radiation slot 22 arranged on the second shell 12, so that the slot antenna has multiple radiation slots formed by the third radiation slot 23 arranged on the first shell 11 and the first radiation slot 21 and the second radiation slot 22 arranged on the second shell 12.

[0075] Taking the electronic device as a laptop computer as an example, based on the above embodiments, in one embodiment of the present application, the first shell is the D shell of the electronic device, and the second shell is at least a portion of the side shell (side wall) connected to the edge of the first shell, so as to avoid setting too many gaps on the C shell of the electronic device, affecting the usable area of ​​the C shell of the electronic device.

[0076] Optionally, in the above embodiment, the second radiation slot is connected to the first radiation slot and the third radiation slot.

[0077] In other embodiments of the present application, the radiation slot may also adopt other structures, which is not limited in the present application and depends on the specific circumstances.

[0078] On the basis of any of the above embodiments, in one embodiment of the present application, the angle between the plane where the first shell is located and the plane where the second shell is located is in a first angle range, and the first angle range can be 0° to 90°, including 90° but excluding 0°. Optionally, the plane where the first shell is located and the plane of the second shell can be perpendicular or non-perpendicular, which is not limited in the present application and depends on the specific circumstances.

[0079] On the basis of any of the above embodiments, in one embodiment of the present application, the angle between the extension directions of the first radiation slot and the second radiation slot is in a second angle range, and the second angle range can be 0° to 90°, including 90° but excluding 0°. Optionally, the extension directions of the first radiation slot and the second radiation slot can be perpendicular or non-perpendicular, which is not limited in the present application and depends on the specific circumstances.

[0080] On the basis of any of the above embodiments, in one embodiment of the present application, the angle between the extension directions of the second radiation slot and the third radiation slot is in a third angle range, and the third angle range can be 0° to 90°, including 90° but excluding 0°. Optionally, the extension directions of the second radiation slot and the third radiation slot can be perpendicular or non-perpendicular, which is not limited in the present application and depends on the specific circumstances.

[0081] Optionally, in one embodiment of the present application, the first shell and the second shell are located on two planes perpendicular to each other, so that the radiation slot on the first shell is perpendicular to the radiation slot on the second shell; the extension directions of the first radiation slot and the third radiation slot are parallel, and the extension directions of the second radiation slot and the first radiation slot are perpendicular, so that the first radiation slot, the second radiation slot and the third radiation slot form an "H"-shaped radiation slot or an "I"-shaped radiation slot. However, the present application does not limit this, as long as the electronic device includes at least one of the following: the first shell and the second shell are located on two planes perpendicular to each other; the extension directions of the first radiation slot and the third radiation slot are parallel; the extension directions of the second radiation slot and the first radiation slot are perpendicular.

[0082] Optionally, in one embodiment of the present application, Figure 3 As shown, when the first radiation slot 21, the second radiation slot 22 and the third radiation slot 23 form an "H"-shaped radiation slot or an "I"-shaped radiation slot, each of the multiple resonant loops includes at least a portion of the second radiation slot, and the first radiation slot 21, the second radiation slot 22 and the third radiation slot 23 form an "I"-shaped radiation slot including at least a first resonant loop A1, a second resonant loop A2, a third resonant loop A3 and a fourth resonant loop A4. Optionally, each resonant loop includes at least a portion of the second radiation slot, but the present application does not limit this, and it depends on the specific situation.

[0083] The electronic device provided in the embodiment of the present application is described below by taking the example that the first radiation slot, the second radiation slot and the third radiation slot form an “I”-shaped radiation slot.

[0084] In the electronic device provided in the embodiment of the present application, current passes through both the first radiation slot and the third radiation slot, which not only makes the current path of the antenna more complicated, but also extends the current path length in the resonant loop formed by the multiple radiation slots, forming a closed short-circuited dipole slot antenna, and then forming multiple short-circuited resonant slots to radiate signals to the outside, increasing the bandwidth of the antenna of the electronic device, and enhancing the radiation field pattern of the antenna, thereby improving the radiation performance of the slot antenna and achieving more efficient transmission and reception of electromagnetic waves.

[0085] According to the Babinet principle, the directional functions of an ideal slot antenna and a linear dipole antenna are the same. Specifically, in one embodiment of the present application, the current path length in each of the multiple resonant circuits satisfies the same condition as 1 / 2 of the wavelength of the center frequency of the antenna frequency band to which it corresponds. It should be noted that, in the present embodiment, the current path length in each resonant circuit satisfies the same condition as 1 / 2 of the wavelength of the center frequency of the antenna frequency band to which it corresponds. The current path length in each resonant circuit may be the same as 1 / 2 of the wavelength of the center frequency of the antenna frequency band to which it corresponds, or the current path length in each resonant circuit may be substantially the same as 1 / 2 of the wavelength of the center frequency of the antenna frequency band to which it corresponds. The present application does not limit this, and it depends on the specific circumstances.

[0086] It should be noted that the resonant frequency f of the half-wave dipole slot antenna roughly satisfies the following formula:

[0087]

[0088] Among them, f is the resonant frequency, c is the speed of light, L is the path length of different resonant circuits, and ε is the relative dielectric constant. According to this formula, the initial value of the current path length L of the resonant circuit can be obtained.

[0089] Specifically, using formula (1), it can be obtained that the current path lengths of the first resonant circuit, the second resonant circuit, the third resonant circuit, and the fourth resonant circuit approximately satisfy the following formula:

[0090]

[0091] Optionally, in one embodiment of the present application, f1, f2, f3, and f4 are 2.4g, 5g, 6g, and 7g, respectively. In this embodiment, L1, L2, L3, and L4 are adjusted by impedance adjustment, so that the electronic device can radiate and receive antenna signals in the 2.4g, 5g, 6g, and 7g frequency bands.

[0092] In addition, in the electronic device provided in the embodiment of the present application, the first radiation slot and the third radiation slot are both used to radiate signals, and their widths can be made smaller, such as less than 2 mm, so there is no need to fill insulating positions such as plastic. In the manufacturing process of the electronic device, the secondary injection molding step is avoided, which is beneficial to the ID design of the electronic device and helps to reduce the cost of the electronic device.

[0093] Optionally, in one embodiment of the present application, Figure 4 As shown, the width D of the third slit 23 on the second shell is not greater than 2 mm, so that the width of the third slit on the second shell is small, improving the consistency of the appearance of the second shell, thereby improving the consistency of the appearance of the electronic device. In addition, since the width of the third slit on the second shell is small, the third slit does not need to be filled with insulating materials such as plastic, which can reduce the process of the electronic device and reduce the cost of the electronic device.

[0094] Optionally, in one embodiment of the present application, the electronic device also includes a third shell parallel to the first shell, the first radiation slot and the second radiation slot are located on the second shell, and the third radiation slot is located on the first shell. Optionally, in this embodiment, the distance between the side of the first radiation slot away from the second radiation slot and the third shell is greater than 1 mm, and the value range can be 1 mm to 2 mm, so as to avoid the distance between the first radiation slot and the third shell being too close, increasing the risk of the first radiation slot being partially bent to the side of the third shell, affecting the field pattern of the signal radiated by the electronic device, but the present application is not limited to this, and it depends on the specific circumstances.

[0095] Based on any of the above embodiments, in one embodiment of the present application, the metal shell also includes a third shell connected to the edge of the second shell. Taking the electronic device as a laptop computer as an example, if the first shell is the C shell of the laptop computer, the third shell is the D shell of the laptop computer, and the second shell is located in a partial area of ​​the side wall between the C shell and the D shell of the laptop computer.
