The shape of the first slit 161 is a rectangle, although the shape of the first slit 161 may be a square or other shapes, and the specific shape of the first slit 161 is not particularly limited in this embodiment.
As shown in fig. 7, a first opening 164 is disposed between the first slit 161 and the second slit 162, and a second opening 165 is disposed between the first slit 161 and the third slit 163.
Wherein the second antenna structure 52 is disposed at a position near the left side wall of the upper end periphery of the carrier 16, and the second antenna structure 52 is adjacent to the second slot 162.
Wherein the GPS antenna structure 53 is disposed at the upper end periphery of the carrier 16 near the right side wall. The GPS antenna structure 53 is adjacent to the third slot 163, and the first antenna structure 51 is closer to the GPS antenna structure 53 than the second antenna structure 52.
In some embodiments, the tuning switch 55 switches the radiation frequency band of the first antenna structure 51, so as to realize radiation of the full frequency band of the antenna structure, where the full frequency band includes signals of the low frequency band (700-.
The rf module 54 is divided into a low frequency port 541, an intermediate frequency port 542, and a high frequency port 543 by a combiner. It should be noted that the radiation frequency band of the first antenna structure 51 can be switched by adjusting the connection between the tuning switch 55 and the low frequency port 541, the intermediate frequency port 542, and the high frequency port 543 of the rf module 54. Of course, the rf module 54 may be divided into the low frequency port 541, the intermediate frequency port 542 and the high frequency port 543 in other manners, and the specific form of the rf module 54 that is divided into the low frequency port 541, the intermediate frequency port 542 and the high frequency port 543 is not particularly limited.
Because the tuning switch 55 is provided, different radiation frequency bands of the first antenna structure 51 can be switched, specifically including low-frequency band (700 + 960MHz), medium-frequency band (1710 + 2170MHz) and high-frequency band (2300 + 2690MHz) signals, so that full-frequency band radiation of one antenna structure is realized, thereby reducing production cost, reducing bit error rate and improving transmission speed.
The electronic device further includes a processor 60, where the processor 60 is configured to obtain a radiation frequency band of the first antenna structure 51, and control a connection relationship between the GPS antenna structure 53 and the radio frequency module 54 through the control switch 56.
On the premise of realizing the full-band radiation of the first antenna structure 51, because the first antenna structure 51, the second antenna structure 52 and the GPS antenna structure 53 are located at the same end of the carrier 16, because of the limitation of the width of the whole device, the GPS antenna structure 53 is adjacent to the first antenna structure 51, the physical distance between the GPS antenna structure 53 and the first antenna structure 51 is short, and especially when the frequencies of the GPS antenna structure 51 and the first antenna structure 51 are also close, the GPS antenna structure 53 will reduce the use efficiency of the first antenna structure 51. For example, the coverage range of the GPS antenna 53 is 1500-. And determining the connection relationship between the GPS antenna structure 53 and the radio frequency module 54 according to the radiation frequency band of the first antenna structure 51. When the first antenna structure 51 is switched to the intermediate frequency, the GPS antenna structure 53 is disconnected from the radio frequency module 54, thereby reducing the effect of the GPS antenna structure 53 on the efficiency of the main antenna structure and improving the efficiency of the antenna assembly.
The processor 60 and the control switch 56 may be an integrated logic control switch 56, or the processor 60 and the control switch 56 may be provided separately, and the processor 60 is connected to the control switch 56 to control the control switch 56.

When the first antenna structure 51 is switched to a low frequency or a high frequency, the control switch 56 connects the GPS antenna structure 53 to the rf module 54. When the first antenna structure 51 is switched to a low frequency or a high frequency, the control switch 56 connects the GPS antenna structure 53 to the rf module 54. When the first antenna structure 51 is switched to the intermediate frequency, the GPS antenna structure 53 is disconnected from the radio frequency module 54, thereby reducing the effect of the GPS antenna structure 53 on the efficiency of the main antenna assembly and improving the efficiency of the antenna assembly 50.

The antenna switching method is applied to an electronic device, the electronic device comprises a processor 60 and an antenna assembly 50, the antenna assembly 50 comprises a first antenna structure 51, a second antenna structure 52, a GPS antenna structure 53, a radio frequency module 54, a tuning switch 55 and a control switch 56, and the control switch 56 and the tuning switch 55 are coupled with the processor 60; the first antenna structure 51 is close to the GPS antenna structure 53, the second antenna structure 52 is far from the GPS antenna structure 53, the first antenna structure 51 is a main diversity antenna, and the second antenna structure 52 is a diversity antenna; a radio frequency module 54 coupled to the first antenna structure 51, the second antenna structure 52 and the GPS antenna structure 53 through a control switch 56;
s101, the processor 60 obtains a radiation frequency band of the first antenna structure 51;
s102 the processor 60 controls the connection relationship between the GPS antenna structure 53 and the radio frequency module 54 through the control switch 56.
It should be noted that the tuning switch 55 switches the radiation frequency band of the first antenna structure 51, so as to realize radiation of the full frequency band of the antenna structure, where the full frequency band includes signals of the low frequency band (700-.
When the first antenna structure 51 is switched to the intermediate frequency, the control switch 56 disconnects the GPS antenna structure 53 from the radio frequency module 51. For example, when the first antenna structure 51 is converted from a low frequency to an intermediate frequency, the processor 60 detects that the radiation frequency band of the first antenna structure 51 reaches 1710MHz, and disconnects the GPS antenna structure 53 from the radio frequency module 54, or when the processor 60 detects that the radiation frequency band of the first antenna structure 51 reaches 2170MHz when the first antenna structure 51 is converted from a high frequency to an intermediate frequency, and disconnects the GPS antenna structure 53 from the radio frequency module 54, so that the radiation efficiency of the GPS antenna structure 53 to the first antenna structure 51 in the intermediate frequency band is not reduced, thereby providing the performance of the antenna assembly 50.
When the first antenna structure 51 is switched to a low frequency or a high frequency, the control switch 56 connects the GPS antenna structure 53 to the rf module 54.
