In this embodiment, the diversity antenna 500 is disposed on the left side of the upper end of the housing 200, and the left side of the housing 200 is "left" when the display screen of the electronic device faces the user.
The third radiator 510 is an integral part of the first metal frame 110 of the electronic device. 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.

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 of the DIV ANT and the DIV MIMO ANT can be improved.
Referring to fig. 3, further, the antenna structure 10 may further include a main antenna 600. The main antenna 600 is disposed at an end of the housing 200 away from the WIFI & GPS antenna 300. In this embodiment, the MAIN antenna 600 is denoted by MAIN ANT.

In this embodiment, the left end of the fourth radiator 610 is spaced from the metal middle frame 130, and the right end extends toward the right side of the case 200 and is spaced from the right edge of the case 200. Alternatively, the left end of the fourth radiator 610 may be spaced apart from the metal middle frame 130 by 1.6 to 2mm. And, a distance between a left end face of the fourth radiator 610 and an end face of the case 200 remote 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.
Further, the antenna structure 10 may also include a primary multiple-input multiple-output antenna 700.

One end of the fifth radiator 710 is spaced apart from the fourth radiator 610, and the other end is spaced apart from the metal middle frame 130 at the other side of the electronic device. In this embodiment, the fifth radiator 710 is bent from the edge of the end of the housing 200 away from the first radiator 310 to the edge of the right side of the housing 200. Alternatively, the left end of the fifth radiator 710 may be spaced from the fourth radiator 610, and the right end of the fifth radiator 710 may be spaced from the metal middle frame 130 by 1.6 to 2mm.

The sixth antenna loop segment 820 and the sixth antenna feed 830 are each connected to a sixth radiator 810. The second antenna loop section 430 is used to provide a ground for the current flowing through the sixth radiator 810. The sixth antenna feeder 830 is spaced from one side edge of the case 200 by 30 to 40mm. In this embodiment, the distance between the sixth antenna feeder 830 and the left side edge of the case 200 is 30-40 mm.
The sixth radiator 810 is spaced from the fourth radiator 610 and the fifth radiator 710, and is used for connecting with an electronic device of the electronic apparatus to be carried by the electronic device. In this embodiment, the sixth radiator 810 is used as a common radiator for the main mimo antenna 700 and the WIFI mimo antenna 800. The sixth radiator 810 may be implemented by using a SPEAKER BOX (SPEAKER BOX) as a carrier and using an antenna technology such as a flexible printed circuit board technology (Flexible Printed Circuit, FPC) or a laser direct structuring technology (Laser Direct Structuring, LDS).
Referring to fig. 4, the sixth radiator 810 includes a first section 811, a second section 812, a third section 813, a fourth section 814, a fifth section 815, a sixth section 816, and a seventh section 817 connected in sequence. The extending directions of the first, third, fifth and seventh sections 811, 813, 815 and 817 are substantially perpendicular to the opposite sides of the housing 200, and the second, fourth and sixth sections 812, 814 and 816 are substantially parallel to the opposite sides of the housing 200 and are the same as the extending directions of the housing 200. In this embodiment, one end of the first segment 811 starts from a position on the left side of the middle of the lower end of the housing 200, and the other end of the first segment 811 extends toward the left side of the housing 200 and is connected to one end of the second segment 812. The other end of the second section 812 extends away from the fourth radiator 610 and is connected to one end of the third section 813. The other end of the third section 813 extends toward the left side of the housing 200 and is connected to one end of the fourth section 814. The other end of the fourth section 814 is connected to one end of the fifth section 815. The other end of the fifth section 815 extends toward the right side of the housing 200 and connects to one end of the sixth section 816 across the midline of the housing 200. The other end of the sixth section 816 extends toward the fourth radiator 610 and is connected to one end of the seventh section 817. The length of the sixth section 816 is approximately equal to the sum of the lengths of the second section 812 and the fourth section 814. The other end of the seventh section 817 extends toward the left side of the housing 200 and is disposed opposite to the start end of the first section 811 at a distance. The length of the fifth segment 815 is approximately equal to the sum of the length of the first segment 811, the length of the third segment 813, the length of the seventh segment 817, and the distance between the first segment 811 and the seventh segment 817.
Note that, the main antenna 600, the main MIMO antenna 700, the diversity MIMO antenna 400, and the diversity antenna 500 together form LTE4×4MIMO, and the WIFI & gps antenna 300 and the WIFI MIMO antenna 800 together form WLAN2×2MIMO. In this embodiment, the LTE 4*4MIMO+WLAN 2*2MIMO+GPS antenna system with better competitiveness is realized by slotting and cutting off at proper positions, reasonable antenna combination and antenna multiplexing in the stacking environment of the metal frame 100 and the complete machine, such as front-mounted structure light shooting, front-mounted double-light-compensating lamp, front-mounted double-camera and the like, and the antenna performance is ensured.
