However, in electronic devices, coupling may occur between two adjacent antennas operating on the same frequency band, which can interfere with the normal operation of the communication antennas in the electronic device. Summary of the Invention

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0033] Please see Figure 1 , Figure 1 This is one of the structural schematic diagrams of the electronic device provided in the embodiments of this application. For example... Figure 1 As shown, the electronic device includes an antenna radiator 10, a first feed port P1, a second feed port P2, a ground plane 20, and a conductor 30;

[0034] The first end of the antenna radiator 10 is electrically connected to the ground plane 20 through the conductor 30.

[0035] The first feed port P1 is disposed at the second end of the antenna radiator 10, and the first feed port P1 is electrically connected to the second end of the antenna radiator 10 to form a first antenna;

[0036] The second feed port P2 is disposed in the low-resistivity region of the antenna radiator 10, and the second feed port P2 is electrically connected to the low-resistivity region of the antenna radiator 10 to form a second antenna.

[0037] like Figure 1 As shown, the first feed port P1 is electrically connected to the second end of the antenna radiator 10 to form the first antenna; the second feed port P2 is electrically connected to the low-resistance region of the antenna radiator 10 to form the second antenna, wherein the first antenna and the second antenna are antennas in the same frequency band.

[0038] Optionally, the operating frequency band of the antenna radiator 10 is 2.5 GHz, and the first and second antennas are LOOP antennas, forming a shared radiator. Figure 1 Two loop antennas of the central antenna radiator 10.

[0039] It should be understood that in other embodiments, the operating frequency band of the antenna radiator 10 may be 400MHz, 6GHz, or other frequency bands; the first antenna and the second antenna may be dipole antennas, monopole antennas, or other types of antennas; the following content is only for the purpose of illustrating the technical solution, taking the operating frequency band of the antenna radiator 10 as 2.5GHz and the first antenna and the second antenna as LOOP antennas as examples, and does not specifically limit the operating frequency band and antenna type.

[0040] When the first feed port P1 receives a feed signal to excite the first antenna, based on the current distribution on the surface of the antenna radiator 10, the low-resistance region of the antenna radiator 10 is determined, that is, the region with the lowest impedance on the outer surface of the antenna radiator 10. The second feed port P2 is then placed in this low-resistance region. The second feed port P2 can be understood as a load, and optionally, its resistance is set to 50 ohms. It should be understood that when the operating frequency band of the antenna radiator 10 is 2.5 GHz, the low-resistance region of the antenna radiator 10 is located in the central region of the antenna radiator 10; therefore, the second feed port P2 can be placed in the central region of the antenna radiator 10.

[0041] Please see Figure 2 , Figure 2 The figure shows the simulation results of the S-parameters, i.e., the scattering parameters, of the antenna radiator 10. Figure 2 The simulation results involve three S-parameters: S11, S22, and S21. S11 is the input reflection parameter, S22 is the output reflection parameter, and S21 is the forward transmission parameter. Figure 2 The horizontal axis represents frequency bands, and the vertical axis represents decibels. From Figure 2 It can be seen that in the N41 band, i.e. the 2490MHz-2690MHz band, the minimum S21 parameter is -12.399dB, indicating that the isolation effect between the first antenna and the second antenna is good.

[0042] To further illustrate the isolation effect between the first and second antennas, please refer to [link / reference]. Figure 3 , Figure 3 This is a schematic diagram of the current distribution on the surface of the antenna radiator 10, expressed in vector form, when the first antenna is excited through the first feed port P1. Figure 3 As shown, when the first antenna is excited through the first feed port P1, the current flowing from the first feed port P1 to the second feed port P2 is small, indicating that isolation is formed between the first feed port P1 and the second feed port P2.

Figure 4 , Figure 4 This is a schematic diagram of the current distribution on the surface of the antenna radiator 10, expressed in vector form, when the second antenna is excited through the second feed port P2. Figure 4 As shown, when the second antenna is excited through the second feed port P2, the current flowing from the second feed port P2 to the first feed port P1 is small, indicating that isolation is formed between the first feed port P1 and the second feed port P2.

[0044] For further details, please refer to Figure 5 , Figure 5 The diagram shows the equivalent circuit diagrams of the first and second antennas. It's easy to understand that the first end of the antenna radiator 10 is electrically connected to the ground plane 20 via a conductor 30, which is equivalent to the antenna radiator 10 being electrically connected to a first resistor R1 with a resistance of 0 ohms. The first feed port P1 and the second feed port P2 can each be equivalent to a load. When the first antenna is excited through the first feed port P1, the second feed port P2 is short-circuited, and the current flowing from the first feed port P1 to the second feed port P2 is small. When the second antenna is excited through the second feed port P2, the first feed port P1 is short-circuited, and the current flowing from the second feed port P2 to the first feed port P1 is small. This creates isolation between the first feed port P1 and the second feed port P2, achieving decoupling between the first and second antennas.

The first feed port P1 is located at the second end of the antenna radiator 10 and is electrically connected to the second end of the antenna radiator 10, forming a first antenna. The second feed port P2 is located in the low-resistivity region of the antenna radiator 10 and is electrically connected to the low-resistivity region of the antenna radiator 10, forming a second antenna. In this embodiment, by placing the second feed port P2 in the low-resistivity region of the antenna radiator 10, when the first feed port P1 receives a feed signal to excite the first antenna, or when the second feed port P2 receives a feed signal to excite the second antenna, isolation is formed between the first feed port P1 and the second feed port P2, thereby achieving decoupling between the first antenna and the second antenna and avoiding coupling between the first antenna and the second antenna in the same frequency band.

If the length is 120mm, then the length of the antenna radiator 10 is 120mm. The length between the first feed port P1 and the second feed port P2 can be set as follows: That is, 63mm; the width of the antenna radiator 10 is set to... That is, 2mm; the distance between the antenna radiator 10 and the ground plane 20 is set to... That is, 4mm.

[0049] Optionally, the conductor 30 is an inductor L, and the length of the antenna radiator 10 is less than the antenna wavelength corresponding to the antenna radiator 10.

[0050] Please see Figure 6 ,like Figure 6 As shown, by setting the conductor 30 as an inductor L, the resonant length of the antenna radiator 10 is changed. While reducing the length of the antenna radiator 10, the first and second antennas can still resonate in the same frequency band. Optionally, the inductor L is a 3.9nH inductor.

[0051] The simulation results of the S-parameters of the antenna radiator 10 are as follows: Figure 7 As shown, from Figure 7 It can be seen that in the N41 band, the minimum S21 parameter is -9.6dB, indicating that the isolation effect between the first antenna and the second antenna is good.

[0053] For further details, please refer to Figure 10 It is easy to understand that the first end of the antenna radiator 10 is electrically connected to the ground plane 20 through the inductor L, which is equivalent to the antenna radiator 10 being electrically connected to the inductor L. When the first antenna is excited through the first feed port P1, the second feed port P2 is short-circuited, and the current flowing from the first feed port P1 to the second feed port P2 is small. When the second antenna is excited through the second feed port P2, the first feed port P1 is short-circuited, and the current flowing from the second feed port P2 to the first feed port P1 is small. In this way, isolation is formed between the first feed port P1 and the second feed port P2, achieving decoupling between the first antenna and the second antenna.

[0054] In this embodiment, when the operating frequency band of the antenna radiator 10 is 2.5GHz, the antenna wavelength corresponding to the antenna radiator 10 is... If the length is 120mm, then the length of the antenna radiator 10 is That is, 100mm.

[0061] It should be understood that for each boss, a distance d1 is defined between the boss and the first sidewall of the oppositely arranged groove, and a distance d2 is defined between the boss and the second sidewall of the oppositely arranged groove, thereby reducing the length of the antenna radiator 10. It should be understood that subsequently... Figure 11 and Figure 16In this context, d1 represents the distance between the boss and the first sidewall of the oppositely positioned groove, and d2 represents the distance between the boss and the second sidewall of the oppositely positioned groove.
