One end of the third radiator 510 is spaced apart from one end of the first radiator 310, and one end of the third radiator 510 remote from the first radiator 310 is spaced apart from the metal middle frame 130 of one side of the electronic device. Alternatively, the interval between the first radiator 310 and the third radiator 510 and the interval between the third radiator 510 and the metal middle frame 130 may be 1.6 to 2mm. And, the distance between the end surface of the third radiator 510 near the first radiator 310 and the side of the case 200 where the third radiator 510 is provided is 5 to 15mm, that is, the distance between the gap between the third radiator 510 and the first radiator 310 and the side of the case 200 where the third radiator 510 is provided is 5 to 15mm.

In this embodiment, the third radiator 510 is disposed on the left side of the housing 200. Also, the third radiator 510 extends to one side of the case 200 by bending from a position adjacent to one end of the first radiator 310, that is, the third radiator 510 extends to the left upper portion of the case 200 by bending from the side of the upper end through the left corner.
In the present embodiment, the third antenna loop section 530 is disposed at a position adjacent to one end of the metal center 130 of the third radiator 510 near the left side. Of course, the position of the third antenna loop segment 530 may be flexibly adjusted by moving left and right as needed for the actual commissioning length of the antenna. The third antenna feed 550 is disposed adjacent to an end of the third radiator 510 near the first radiator 310.
Note that, the first radiator 310, the second radiator 410, and the third radiator 510 are all used as the first metal frame 110 of the electronic device, that is, the first radiator 310, the second radiator 410, and the third radiator 510 together form the first metal frame 110.
In addition, the frequency band of the signal received by the second radiator 410 partially overlaps the frequency band of the signal received by the third radiator 510, and the first radiator 310 is disposed between the second radiator 410 and the third radiator 510 and is spaced apart from both the second radiator 410 and the third radiator 510. This can enhance the isolation between the second radiator 410 and the third radiator 510, and improve the performance of the whole antenna structure 10, so that a space can be left for functional features of the electronic device, for example, a structure light front-end shooting or a front-end dual-light-compensating lamp or a front-end dual-camera can be realized.
In this embodiment, the frequency band overlap ratio of the signals between the first radiator 310 and the second radiator 410 and between the first radiator 310 and the third radiator 510 is much smaller than the frequency band overlap ratio of the signals between the second radiator 410 and the third radiator 510. In this embodiment, the DIV ANT and the DIV MIMO ANT are designed on both sides of the WIFI & GPS ANT, so that the problem of isolation between 1710MHZ and 2300MHZ between the DIV ANT and the DIV MIMO ANT can be improved.
Referring to fig. 3, further, the antenna structure 10 may further include a fourth single antenna 600.

The fourth radiator 610 is used as the second metal frame 150 of the electronic device, and two ends of the fourth radiator 610 are respectively used for being spaced from the metal middle frame 130 of the electronic device. Alternatively, the intervals between the both ends of the fourth radiator 610 and the metal middle frame 130 may be 1.6-2 mm, respectively. And, a distance between an end surface of the fourth radiator 610 near the metal middle frame 130 and an end surface of the case 200 far from the first radiator 310 is 11 to 21mm. That is, the distance between the interval between the fourth radiator 610 and the metal middle frame 130 and the end surface of the case 200 remote from the first radiator 310 is 11 to 21mm.
In this embodiment, the fourth radiator 610 is disposed at an edge of one end of the housing 200 away from the first radiator 310, and one end of the fourth radiator 610 is bent and extended to an edge of one side of the housing 200, and is spaced from the metal middle frame 130 disposed at one side of the housing 200; the other end is bent and extended to the other side edge of the housing 200 and is spaced from the metal middle frame 130 disposed at the other side of the housing 200.

The fifth single antenna 700 is disposed at a lower portion of the housing 200, near the location of the fourth single antenna 600. The fifth single antenna 700 is spaced apart from the fourth single antenna 600, and the fifth single antenna 700 is used for radiating a signal synthesized by a combiner from a first signal source and a second signal source in the electronic device. In this embodiment, the first signal source is generated by a MAIN MIMO antenna, which is denoted MAIN MIMO ANT. The second signal source is generated by a WIFI multiple-input multiple-output antenna, denoted as WIFI MIMO ANT. It is appreciated that the fifth single antenna 700 acts as a common radiating antenna for both the primary mimo antenna and the WIFI mimo antenna.
The fifth single antenna 700 has a fifth radiator 710, a fifth antenna loop segment 720 and a fifth antenna feed 730. The fifth antenna loop segment 720 and the fifth antenna feed 730 are both connected to the fifth radiator 710. The second antenna loop segment 430 is used to provide a ground for the current flowing through the fifth radiator 710. The distance between the fifth antenna feeder 730 and one side edge of the case 200 is 30-40 mm.
