One end of the first antenna structure 81 is connected to the main ground portion 222, and other portions of the first antenna structure 81 are separated from the main ground portion 222 by a third gap 33. The second antenna structure 82, the third antenna structure 83, and the fourth antenna structure 84 adopt structures similar to the first antenna structure 81.

In some embodiments, each feeding end 811 is connected to a signal source 90 through a matching circuit 71, and each signal source 90 transmits two antenna signals of different frequency bands at the same time.

Each signal source 90 can simultaneously transmit antenna signals of two frequency bands. For example, the antenna signals include antenna signals of two bands of N78 (3.3GHz to 3.6GHz) and N79 (4.8GHz to 5GHz). Each signal source 90 transmits at the same time. For the antenna signals of the N78 frequency band and the N79 frequency band, the four matching circuits 71 adjust their internal circuits so that their corresponding antenna structures transmit the antenna signals of the N78 frequency band and the N79 through different sub-antenna structures. Similarly, when receiving the antenna signal, it also receives the antenna signals of the N78 frequency band and N79 at the same time.

In some embodiments, the lengths of the two sub-antenna structures connected to the same feeding end are different, and the matching circuit 71 transmits the antenna signals of the two different frequency bands respectively through the two sub-antenna structures simultaneously.

The two antenna structures of each of the first antenna structure 81, the second antenna structure 82, the third antenna structure 83, and the fourth antenna structure 84 have different lengths. In this way, the antenna signals of the two frequency bands can be matched respectively. Furthermore, two antenna signals of different frequency bands are transmitted simultaneously through two sub-antenna structures.

Please continue to combine FIG. 5, which is a schematic diagram of a first antenna structure according to an embodiment of the present application. In some embodiments, each matching circuit 71 includes a capacitor 72, one end of the capacitor 72 is connected to the signal source 90, and the other end of the capacitor 72 is connected to the feeding end of the antenna structure.

Specifically, the antenna structure uses a capacitor 72 for coupling and feeding, and adjusting the feeding position and the feeding capacitance value on the antenna structure can make the first sub-antenna structure 811 in the antenna structure a loop mode antenna structure. And let the second sub-antenna structure 812 be an IFA mode antenna structure. The sub-antenna structures of the two modes are respectively located in different frequency bands, thereby achieving coverage of the antenna signals of the two frequency bands. For example, the two sub-antenna structures are respectively located in the N78 (3.3GHz to 3.6GHz) and N79 (4.8GHz to 5GHz) frequency bands of the 5G antenna, thereby achieving coverage of the domestic 5G frequency band. Specifically, as shown in the drawing, an antenna signal of the first sub-antenna structure 811 is transmitted along a path shown by a dotted line 721, and an antenna signal of the second sub-antenna structure 812 is transmitted along a path shown by a dotted line 722. It can be understood that the antenna signal in this embodiment is a current signal flowing along the antenna structure.

In some embodiments, in some embodiments, the first antenna structure 81, the second antenna structure 82, the third antenna structure 83, and the fourth antenna structure 84 are the same antenna structure, and the same matching circuit is connected to each antenna structure. For the same matching circuit.

The first antenna structure 81, the second antenna structure 82, the third antenna structure 83, and the fourth antenna structure 84 are all the same, which is convenient for setting the antenna structure, and it is also convenient to set the matching circuit of each antenna structure. When adjusting the parameters of the antenna structure in stages, it is also simpler and easier to adjust the parameters of the antenna structure. At the same time, each antenna structure constitutes a Multiple-Input Multiple-Output (MIMO) antenna, which can better cooperate with each other when transmitting or receiving antenna signals of the same frequency band at the same time.

In some embodiments, the length of one antenna structure among the first antenna structure 81, the second antenna structure 82, the third antenna structure 83, and the fourth antenna structure 84 is different from that of the other antenna structures.

Because the functional devices set at various positions of the electronic device are different, or the structural design of the electronic device is required, the four antenna structures cannot be provided at the same position. For example, if a key is required around the third antenna structure 83, the length of the third antenna structure 83 is shorter than that of other antenna structures. Thus, the matching circuit of the third antenna structure 83 may include an inductor, which is equivalent to The length of the third antenna structure 83 is extended. Of course, it is also possible to set a longer length because the clearance environment around the third antenna structure 83 is good, while other antenna structures have shorter lengths due to various environmental restrictions and need to use matching circuits to implement the transmission and reception of antenna signals.

In some embodiments, the main ground portion 222 is grounded, the first antenna structure 81 and the second antenna structure 82 are grounded through the first side portion 221, and the third antenna structure 83 and the fourth antenna structure 84 are connected through the second side portion 223 Ground.

Specifically, the first middle portion 2212 and the second middle portion 2232 are grounded through the main ground portion 222, the third end portion 2211 and the fourth end portion 2213 are grounded through the first middle portion 2212, the fifth end portion 2231, and the sixth end. The portion 2233 is grounded through the second intermediate portion 2232. The main ground portion 222 of the metal middle frame 20 is grounded. In this way, the first middle portion 2212 and the second middle portion 2232 connected to the main ground portion 222 are also grounded. The third end portion 2211 and the fourth end portion 2213 pass through the first middle portion. 2212 is grounded, and the fifth end portion 2231 and the sixth end portion 2233 are grounded through the second middle portion 2232. Each antenna structure does not need to be additionally provided with a ground point, and is directly grounded through the end connected to the main ground portion 222. At the same time, the strength of the metal middle frame 20 can be enhanced.

In some embodiments, the end of the first antenna structure 81 connected to the main ground portion 222 is a first ground point. It can be understood that the end of the first antenna structure 81 connected to the first intermediate portion 2212 is a first ground point. The end of an antenna structure 81 facing the first gap 31 is a first floating end. The antenna structure between the feeding end on the first antenna structure 81 and the first ground point forms a first sub-antenna structure 811. The first antenna structure 81 The antenna structure between the upper feeding end and the first floating end forms a second sub-antenna structure 812.

In this way, the first sub-antenna structure 811 in the antenna structure can be a loop mode antenna structure, and the second sub-antenna structure 812 can be an IFA mode antenna structure. The sub-antenna structures of the two modes are respectively located in different frequency bands, thereby achieving coverage of the antenna signals of the two frequency bands.
