For example, the antenna signal includes antenna signals of three frequency bands, and the frequency band switching module includes three adjusted circuits corresponding to the antenna signals of one frequency band respectively.

In some embodiments, the first frequency band switching point 812 is set between the first feeding end 811 and the first gap 31, and the second frequency band switching point 822 is set between the second feeding end 821 and the second gap 32, The third frequency band switching point 832 is set between the third feeding end 831 and the first gap 31 , and the fourth frequency band switching point 842 is set between the fourth feeding end 841 and the second gap 32 .

The first feeding end 811 of the first antenna structure 81 is arranged opposite to the first gap 31, that is, the first feeding end 811 is arranged away from the first gap 31, and the antenna signal enters the first antenna structure 81 from the first feeding end 811. , and radiate from the end of the first antenna structure 81 adjacent to the first gap 31 , utilizing the length of the first antenna structure 81 as much as possible. The second antenna structure 82 , the third antenna structure 83 and the fourth antenna structure 84 radiate signals in a similar manner to the first antenna structure 81 .

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, the first frequency band switching module 71, the second frequency band switching module 72, the The three-band switching module 73 and the fourth frequency-band switching module 74 are the same frequency-band switching module.

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, so it is convenient to set the antenna structure, and it is also convenient to set the matching circuits of each antenna structure. At the same time, in the design stage, detection stage, etc. When adjusting the parameters of the antenna structure in stages, it is also easier and more convenient to adjust the parameters of the antenna structure. Each antenna has the same structure, and the corresponding frequency band switching module may also use the same frequency band switching module. The frequency band switching module is set according to the frequency band that needs to switch, for example, the frequency band switching module can include a single pole double throw switch, the first capacitor and the second capacitor, wherein the capacitance value of the first capacitor and the second capacitor is different, the input of the single pole double throw switch The terminal is connected to the frequency band switching point of the antenna structure, and the two input terminals of the single-pole double-throw switch are respectively grounded through the first capacitor and the second capacitor. It can be understood that one or both of the first capacitor and the second capacitor can be replaced by an inductor, or one or both of the first capacitor and the second capacitor can be replaced by an LC circuit (that is, an inductor and a capacitor connected in parallel circuit). Wherein, the values of the first capacitor and the second capacitor are set according to the frequency band corresponding to the antenna structure, and similarly, the values of the inductor and the LC circuit can also be set according to the frequency band corresponding to the antenna structure. It is also possible to replace the first capacitor and the second capacitor with an inductor and an LC circuit.

In some embodiments, one of the first antenna structure 81 , the second antenna structure 82 , the third antenna structure 83 and the fourth antenna structure 84 has a different length than the other antenna structures.

Because of the different functional devices arranged at each position of the electronic device, or the structural design requirements of the electronic device, it is impossible to assign the same position to the four antenna structures. If the position around the third antenna structure 83 needs to be provided with buttons, the length of the third antenna structure 83 is shorter than the length of other antenna structures, so that the matching circuit of the third antenna structure 83 can include an inductor, which is equivalent to The length of the third antenna structure 83 is extended. Of course, the third antenna structure 83 can also be set with a longer length due to the good clearance environment around it, while the other antenna structures have shorter lengths due to various environmental restrictions and need to use matching circuits to cooperate with each other to realize the transmission and reception of antenna signals.

For another example, the second antenna structure 82 is disposed on the third bent portion 232 of the second end portion 23, and the first antenna structure 81, the third antenna structure 83 and the fourth antenna structure 84 are disposed on the first side portion 221 and the second antenna structure. On the two side portions 223, the position of the second antenna structure 82 is different from the positions of the other three antenna structures, the second antenna structure 82 is limited by the third bending portion, and the parameters such as the length and width of the second antenna structure 82 are the same as The other three antenna structures are different, and the matching circuit of the second antenna structure 82 may be different from the matching circuits of the other three antenna structures, so that the performance of the second antenna structure 82 is better than that of the other three antenna structures, or the second antenna structure 82 The performance of the antenna is similar to that of the other three antenna structures.

In some embodiments, the middle part 222 of the main body is grounded, the middle of the first side part 221 and the middle of the second side part 223 are respectively connected to the middle part 222 of the main body, the first antenna structure 81 is grounded through the middle of the first side part 221, The third antenna structure 83 is grounded through the middle of the second side portion 223; the second antenna structure 82 is also provided with a second ground point 823, and the second ground point 823 is arranged between the second feeding end 831 and the seventh gap 37 , the fourth antenna structure 84 is further provided with a fourth ground point 843 , and the fourth ground point 843 is disposed between the fourth feeding end 841 and the eighth gap 38 . Wherein, the second ground point 823 is disposed adjacent to the seventh gap 37 , and the fourth ground point 843 is disposed adjacent to the eighth gap 38 .

In some embodiments, the first antenna system includes a first signal source 91 , an impedance matching network 75 , a first antenna structure 81 , and a first frequency band switching module 71 . The first antenna structure 81 includes a first feeding end 811 , a first frequency band switching point 812 , and a first grounding point 813 . The first feed end 811 of the first antenna structure 81 feeds the electric signal to be transmitted to the first antenna system, and the first feed end 811 of the first antenna structure 81 is connected to the first signal source 91 through the impedance matching network 75, and the impedance The matching network 75 can be composed of concentrated elements such as inductors or capacitors or a combination of the two, which is used to adjust the feeding impedance of the first antenna system, so as to transmit as much signal energy as possible to the first antenna structure 81 . By adjusting the width of the first antenna structure 81, the resonant width (operating bandwidth) of the antenna is adjusted, and the position of the first ground point 813 is moved (that is, the length of the radiator is changed) and the first frequency band switching module 71 (antenna switch or antenna tuning Tuner ) combination to adjust the length of the antenna structure to make it work in the required frequency band.

In some embodiments, the first gap 31 and the second gap 32 in the above embodiment are filled with non-metallic materials (such as plastic, plastic, etc.), so that the first end portion 21, the main body portion 22 and the second end portion 23 are connected. Integrate to improve the strength of the metal middle frame 20.
