At this time, the display screen 10 may display information in a full screen, so that the electronic apparatus 100 has a large screen occupation ratio. The display screen 10 comprises only the display area 11 and no non-display area. At this time, functional components such as a camera and a proximity sensor in the electronic apparatus 100 may be hidden under the display screen 10, and the fingerprint recognition module of the electronic apparatus 100 may be disposed on the back of the electronic apparatus 100.

The middle frame 20 may have a thin plate-like or sheet-like structure, or may have a hollow frame structure. The middle frame 20 can be accommodated in the accommodating space formed by the display screen 10 and the rear cover 50. The middle frame 20 is used for providing a supporting function for the electronic components or functional modules in the electronic device 100, so as to mount the electronic components or functional modules in the electronic device together. For example, functional components such as a camera, a receiver, a circuit board, and a battery in the electronic apparatus may be mounted on the center frame 20 for fixation. In some embodiments, the material of the middle frame 20 may include metal or plastic.

For another example, the rear cover 50 may include a plastic portion and a metal portion, and the rear cover 50 may be a rear cover structure in which metal and plastic are matched with each other. Specifically, the metal part may be formed first, for example, a magnesium alloy substrate is formed by injection molding, and then plastic is injected on the magnesium alloy substrate to form a plastic substrate, so as to form a complete rear cover structure.

In some embodiments, reference is made to fig. 4, wherein electronic device 100 includes oppositely disposed first end 101 and second end 102. It is understood that the first end portion 101 and the second end portion 102 are located at different ends of the electronic device 100. The first end 101 may be, for example, a top end of the electronic device 100. The second end 102 may be, for example, a bottom end of the electronic device 100.

The first end portion 101 is provided with a first antenna. The first antenna may be an IFA antenna (linear inverted F antenna). The first antenna includes a first antenna radiator 61. The first antenna radiator 61 comprises a free end 611. The free end 611 extends in a first direction. For example, the first direction may be toward the left as shown in fig. 4.

The second end 102 is provided with a second antenna. The second antenna may be an IFA antenna. The second antenna comprises a second antenna radiator 62. The second antenna radiator 62 includes a free end 621. The free end 621 extends in the second direction. Wherein the second direction is opposite the first direction such that the pattern of the first antenna is complementary to the pattern of the second antenna. For example, the second direction may be toward the right as shown in fig. 4.

The first direction in which the free end 611 of the first antenna radiator 61 extends and the second direction in which the free end 621 of the second antenna radiator 62 extends are not limited to the above-described exemplary directions. As long as the first direction is opposite to the second direction.

The above description is only given by taking the first antenna and the second antenna as IFA antennas for example. In other embodiments, the first and second antennas may be other types of antennas. For example, the first antenna and the second antenna may be PIFA antennas, monopole antennas, slot antennas, etc. Also, the first antenna and the second antenna may be of different types.

The first antenna and the second antenna are used for receiving and transmitting wireless signals. Specifically, the first antenna may transmit and receive wireless signals through the first antenna radiator 61, and the second antenna may transmit and receive wireless signals through the second antenna radiator 62. For example, the first and

second antenna radiators

61 and 62 may be used to transmit wireless signals to a base station or receive wireless signals transmitted by the base station, so as to implement communication between the electronic device 100 and the base station. It should be noted that the first antenna and the second antenna may both separately complete the transceiving of the wireless signal, that is, the first antenna and the second antenna may both separately complete the communication between the electronic device 100 and the base station.

Referring to fig. 5 and 6, fig. 5 is a schematic signal radiation diagram of the first antenna, and fig. 6 is a schematic signal radiation diagram of the second antenna. In this embodiment, the signal radiation diagrams of the first antenna and the second antenna are directional diagrams. Wherein the first antenna radiates a signal through the first antenna radiator 61 and the second antenna radiates a signal through the second antenna radiator 62. The maximum signal radiation direction of the first antenna radiator 61 is along the first direction. For example, if the first direction is toward the left, the maximum signal radiation direction of the first antenna radiator 61 is the left hemisphere. The maximum signal radiation direction of the second antenna radiator 62 is along the second direction. For example, the second direction is toward the right, and the maximum signal radiation direction of the second antenna radiator 62 is the right hemisphere. Thus, the pattern of the first antenna may be complementary to the pattern of the second antenna.

In some embodiments, the first antenna and the second antenna are both used for transceiving low-frequency signals. Wherein, the low frequency signal can be a signal of a GSM850/900 frequency band. The frequency range of the low frequency signal is 700MHz (megahertz) to 960 MHz. Thus, the pattern of the first antenna in the GSM850/900 frequency band is complementary to the pattern of the second antenna in the GSM850/900 frequency band.

It should be noted that the antenna radiator is most stable when transmitting and receiving a radio signal in the maximum signal radiation direction of the antenna radiator. That is, the first antenna radiator 61 is most stable when transmitting and receiving a wireless signal in the first direction, and the second antenna radiator 62 is most stable when transmitting and receiving a wireless signal in the second direction.

The electronic device 100 may transmit and receive wireless signals through the first antenna, and may also transmit and receive wireless signals through the second antenna, where the first direction is opposite to the second direction, and a directional pattern of the first antenna is complementary to a directional pattern of the second antenna, so that the electronic device 100 may stably transmit and receive wireless signals in the first direction or the second direction, so as to improve communication stability of the electronic device 100.

In some embodiments, the electronic device 100 may switch the antenna radiator that transceives the wireless signal. When the maximum signal radiation direction of the first antenna radiator 61 faces the base station, the electronic device 100 may switch to transmit and receive wireless signals through the first antenna radiator 61, and at this time, the second antenna radiator 62 may be turned off. When the maximum signal radiation direction of the second antenna radiator 62 faces the base station, the electronic device 100 may switch to transmit and receive wireless signals through the second antenna radiator 62, and at this time, the first antenna radiator 61 may be turned off.

Specifically, the electronic device 100 may detect the strength of the wireless signal received by the first antenna radiator 61 and the second antenna radiator 62 in real time. When the strength of the wireless signal received by the first antenna radiator 61 is strong, the electronic device 100 switches to transmit and receive the wireless signal through the first antenna radiator 61; when the strength of the wireless signal received by the second antenna radiator 62 is strong, the electronic device 100 switches to transmit and receive the wireless signal through the second antenna radiator 62.

The circuit board 30 is provided with a first signal source 31 and a second signal source 32. The first signal source 31 and the second signal source 32 are both used for generating wireless signals. For example, the first signal source 31 can be used to generate radio frequency signals with frequencies ranging from 700MHz to 960MHz, 1710MHz to 2170MHz, 2300MHz to 2690 MHz. The second signal source 32 may also be used to generate radio frequency signals in the frequency ranges 700MHz to 960MHz, 1710MHz to 2170MHz, 2300MHz to 2690 MHz.
