Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the application. As shown in fig. 1, the electronic device includes an antenna radiator 10, a first power supply port P1, a second power supply port P2, a ground plate 20, and a conductor 30;
the first end of the antenna radiator 10 is electrically connected to the ground plane 20 through the conductor 30;
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, so as to form a first antenna;
The second feeding port P2 is disposed in the low-resistance region of the antenna radiator 10, and the second feeding port P2 is electrically connected to the low-resistance region of the antenna radiator 10, so as to form a second antenna.
As shown in fig. 1, the first feeding port P1 is electrically connected to the second end of the antenna radiator 10 to form a first antenna, and the second feeding port P2 is electrically connected to the low-resistance region of the antenna radiator 10 to form a second antenna, where the first antenna and the second antenna are the same-band antennas.
Optionally, the operating frequency band of the antenna radiator 10 is 2.5GHz, the first antenna and the second antenna are LOOP antennas, and the first antenna and the second antenna form a common radiator, that is, two LOOP antennas of the antenna radiator 10 in fig. 1 are shared.
It should be understood that, in other embodiments, the operating frequency band of the antenna radiator 10 may be 400MHz, or 6GHz, or other frequency bands, the first antenna and the second antenna may be dipole antennas, monopole antennas, or other types of antennas, and the following description will only refer to the operating frequency band of the antenna radiator 10 as 2.5GHz for the purpose of illustrating the operating frequency band of the antenna radiator 10, and the first antenna and the second antenna are LOOP antennas, which are not limited specifically.
When the first feeding port P1 receives a feeding signal to excite the first antenna, a low resistance region of the antenna radiator 10, that is, a region of the lowest impedance of the outer surface of the antenna radiator 10 is determined based on the current distribution of the surface of the antenna radiator 10, and the second feeding port P2 is disposed in the low resistance region of the antenna radiator 10, wherein the second feeding port P2 may be understood as a load, and optionally, the resistance value of the second feeding port P2 is set to be 50 ohms. It should be understood that when the operating frequency band of the antenna radiator 10 is 2.5GHz, the low resistance region of the antenna radiator 10 is located at the central region of the antenna radiator 10, and thus the second feed port P2 may be disposed at the central region of the antenna radiator 10.
Referring to fig. 2, fig. 2 shows simulation results of S parameters, that is, scattering parameters, of the antenna radiator 10, and fig. 2 shows simulation results of S parameters, that is, S11 parameters, S22 parameters, and S21 parameters, where the S11 parameters are input reflection parameters, the S22 parameters are output reflection parameters, and the S21 parameters are forward transmission parameters, and the abscissa axis in fig. 2 represents a frequency band, and the ordinate axis represents decibels.

As shown in fig. 3, when the first antenna is excited by the first power supply port P1, a small current flows from the first power supply port P1 to the second power supply port P2, which means that isolation is formed between the first power supply port P1 and the second power supply port P2.

As shown in fig. 4, in the case where the second antenna is excited through the second feeding port P2, a small current flowing from the second feeding port P2 to the first feeding port P1 indicates that isolation is formed between the first feeding port P1 and the second feeding port P2.

In the case where the first antenna is excited through the first feeding port P1, the second feeding port P2 is short-circuited, and the current flowing through the first feeding port P1 to the second feeding port P2 is small. When the second antenna is excited by the second feeding port P2, the first feeding port P1 is short-circuited, and the current flowing to the first feeding port P1 from the second feeding port P2 is small. With this, an isolation is formed between the first feeding port P1 and the second feeding port P2, so as to realize decoupling between the first antenna and the second antenna.

And referring to fig. 9, as shown in fig. 9, in the case where the second antenna is excited through the second feeding port P2, a smaller current flows from the second feeding port P2 to the first feeding port P1, indicating that isolation is formed between the first feeding port P1 and the second feeding port P2.
