The shape of the display screen 111 may be a rectangle or an arc-corner rectangle, and the arc-corner rectangle may also be referred to as a rounded rectangle, that is, four corners of the rectangle are in arc transition, and four sides of the rectangle are approximately straight line segments.

The frame 12 may be made of a metal material such as aluminum alloy or magnesium alloy or stainless steel, and the frame 12 is disposed at the periphery of the display screen assembly 11 for supporting and protecting the display screen assembly 11.

Further, display screen subassembly 11 and apron subassembly are located the both sides that back of the body is mutually separately. An installation space can be formed between the cover plate assembly and the display screen 111 for installing electronic components such as a battery, a circuit board, a camera module and the like of the electronic equipment. The circuit board 13 may integrate electronic components such as a processor, a memory unit, a power management module, a radio frequency transceiver, and a baseband processor of the electronic device.

The Circuit Board 13 may be a PCB (Printed Circuit Board) or an FPC (Flexible Printed Circuit). On this circuit board 13, part of radio frequency circuits for processing radio frequency signals may be integrated, including but not limited to antenna components, at least one Amplifier, transceivers, couplers, Low Noise Amplifiers (LNAs), duplexers, etc. In addition, the radio frequency circuitry may also communicate with networks and other devices via wireless communications.

Referring to fig. 2, the middle frame 12 is substantially a rectangular frame, and includes a top frame 121 and a bottom frame 123 disposed opposite to each other, and a first side frame 125 and a second side frame 127 connected between the top frame 121 and the bottom frame 123, where the first side frame 125 and the second side frame 127 are disposed opposite to each other, and the top frame 121, the first side frame 125, the bottom frame 123 and the second side frame 127 are sequentially connected end to end and located at the periphery of the middle plate. The connection between the frames can be a right-angle connection or an arc transition connection. Further, when the frame is a metal frame, the frame 12 may be formed with an antenna for radiating radio frequency signals of different frequency bands. Specifically, the antenna may be formed by a slit provided on the bezel. The antenna in the embodiment of the present application may be used to radiate Long Term Evolution (LTE) signals (for short, 4G LTE signals) and New Radio, NR (NR) signals (for short, 5G NR signals), where the 5G NR signals may also include 5G signals in Sub 6G frequency band. It should be noted that the antenna in the embodiment of the present application may also be used to support NFC, bluetooth, and other communications. In the embodiment of the present application, a specific frequency band of the radio frequency signal that can be radiated by the antenna is not further limited.

As shown in fig. 3, the electronic device further includes a radio frequency system 20, so that the electronic device can operate in a Non-Standalone (NSA) operation mode, a Standalone (SA) operation mode, and a Long Term Evolution (LTE) operation mode (or LTE only operation mode). In the NSA working mode, only one path of emission TX path and four paths of emission RX path are required, and a Sounding Reference Signal (SRS) requires to realize a 1T4R round emission function; in the SA operating mode, there are two TX paths for transmission, and four RX paths for transmission, and the SRS requires to implement the 2T4R round transmission function, and may also support the 1T4R round transmission function. The electronic device in this embodiment can realize that the two-transmission four-reception 2T4R is compatible with the one-transmission four-reception 1T 4R.

With continued reference to fig. 2 and fig. 3, the rf system 20 may include a first antenna ANT0, a second antenna ANT1, a third antenna ANT2, a fourth antenna ANT3, an rf transceiver 210, a first transceiver circuit 220, and a second transceiver circuit 230. Wherein the first antenna ANT0 is formed at the top frame 121, at least a portion of the second antenna ANT1 is formed at the bottom frame 123, the third antenna ANT2 is formed at the first side frame 125, and the fourth antenna ANT3 is formed at the second side frame 127. Due to the structural limitation of the electronic device, during the normal use of the electronic device, since the first antenna ANT0 and the second antenna ANT1 are respectively disposed on the top frame 121 and the bottom frame 123 of the electronic device, and the third antenna ANT2 and the fourth antenna ANT3 are respectively disposed on the two

side frames

125 and 127 of the electronic device. Therefore, the efficiency of each of the first antenna ANT0 and the second antenna ANT1 is higher than that of the third antenna ANT2 and the fourth antenna ANT 3.

The radio frequency transceiver 210 is configured to provide a first radio frequency signal and a second radio frequency signal, where network systems of the first radio frequency signal and the second radio frequency signal are different, and frequency ranges of the first radio frequency signal and the second radio frequency signal are the same. Specifically, the first network may be a 4G network, and the second network may be a 5G network. The first radio frequency signal may include a low frequency signal, an intermediate frequency signal, and a high frequency signal, and the second radio frequency signal may also include a low frequency signal, an intermediate frequency signal, and a high frequency signal. The frequency band division of the first radio frequency signal and the second radio frequency signal is shown in table 1. In addition, the rf transceiver 210 is configured to provide a third rf signal, wherein the third rf signal may be an uhf signal of the second network, such as a 5G NR signal in the N77, N78, and N79 frequency bands.

TABLE 1 shows the frequency band division table for IF signal, HF signal and UHF signal

It should be noted that, in the 5G network, only the identifier before the sequence number is changed along with the frequency band used by 4G. The frequency ranges of the frequency bands with the same serial number are the same. In addition, some ultrahigh frequency bands which are not available in the 4G network, such as N77, N78, N79 and the like, are added to the 5G network.

In the embodiment of the present application, the first radio frequency signal provided by the radio frequency transceiver 210 may include an intermediate frequency signal and a high frequency signal, and the second radio frequency signal provided by the radio frequency transceiver 210 includes the intermediate frequency signal and the high frequency signal. When the electronic device needs to operate in the NSA operation mode, the rf transceiver 210 can provide the first rf signal and the second rf signal having the same frequency range in a time sharing manner. When the electronic device needs to support the SA operation mode, the rf transceiver 210 can provide the first rf signal and the second rf signal with the same frequency range.

The first transceiving circuit 220 is connected to the rf transceiver 210, and configured to transceive the first rf signal and switchably transmit the first rf signal to the first antenna set 240. The first transceiver circuitry 220 may support receive and transmit processing of the first radio frequency signal. Specifically, when transmitting the first rf signal, the first rf signal provided by the rf transceiver 210 may be transmitted to the two antennas of the first antenna group 240. A second transceiving circuit 230, connected to the rf transceiver 210, for transceiving the second rf signal and switchably transmitting the second rf signal to the second antenna group 250. The second transceiver circuitry 230 may support receive and transmit processing of the second radio frequency signal. Specifically, when transmitting the second rf signal, the second rf signal provided by the rf transceiver 210 may be transmitted to the two antennas of the second antenna group 250.

Each of the first antenna set 240 and the second antenna set 250 may include two antennas, and each of the first antenna set 240 and the second antenna set 250 includes two antennas different from each other. That is, the first antenna set 240 may include any two of the first antenna ANT0, the second antenna ANT1, the third antenna ANT2, and the fourth antenna ANT3, and the second antenna set 250 may include two antennas other than the first antenna set 240. Each antenna in the first antenna set 240 and the second antenna set 250 can support transceiving function for 4G LTE signals and 5G NR signals, for example, each antenna in the first antenna set 240 and the second antenna set 250 can support transceiving function for intermediate frequency signals, high frequency signals, and ultra high frequency signals.

The electronic device in this embodiment supports SRS 1T4R and four-antenna switching in the NSA operating mode. In rf transmission, the rf transceiver 210 may provide a first rf signal and a second rf signal having the same frequency range, wherein the first rf signal (e.g., B3 band signal) and the second rf signal (e.g., N3 band signal) are provided in a time-sharing manner. That is, time division may be provided to provide two transmit signals having the same frequency. Wherein, the first signal (for example, the first rf signal B3) may be switched to the first antenna ANT0 and the second antenna ANT1 through the first transceiver circuit 220 to switch transmission between the first antenna ANT0 and the second antenna ANT 1; the second signal (e.g., the second rf signal N3) may be switched to the third antenna ANT2 and the fourth antenna ANT3 via the second transceiving circuit 230 to switch transmission between the third antenna ANT2 and the fourth antenna ANT 3.

In the electronic device of this embodiment, in the SA mode, the rf transceiver 210 can provide two transmission signals simultaneously, so as to implement two-transmission and four-reception 2T 4R. It should be noted that the transmission processing of the first radio frequency signal by the first transceiver circuit 220 and the transmission processing of the second radio frequency signal by the second transceiver circuit 230 need to work simultaneously, that is, the second transceiver circuit 230 transmits the second radio frequency signal while the first transceiver circuit 220 transmits the first radio frequency signal.

The electronic device in the embodiment of the present application includes a metal frame 12 and a radio frequency system 20, where the radio frequency system 20 includes a radio frequency transceiver 210, a first transceiver circuit 220, a second transceiver circuit 230, and four antennas, where the four antennas are respectively formed on a top frame 121, a bottom frame 123, and two side frames of the metal frame in a one-to-one correspondence manner, the first transceiver circuit 220 is switchably connected to two antennas of a first antenna group 240, and the second transceiver circuit 230 is switchably connected to a second antenna group 250. The radio frequency transceiver 210 can provide the first radio frequency signal and the second radio frequency signal with the same frequency range in a time-sharing manner or at the same time, and can enable a target radio frequency signal (for example, an intermediate frequency signal or a high frequency signal with the same frequency range) to be switched over among the four antennas, thereby greatly reducing the probability that the four antennas are simultaneously held by a user, and improving the antenna performance when the electronic device is in a landscape holding state (for example, a landscape holding game scene). In addition, in the electronic device provided in the embodiment of the present application, the first transceiver circuit 220 and the second transceiver circuit 230 are independently arranged, so that flexible layout is facilitated, and the first transceiver circuit 220 and the second transceiver circuit 230 can be respectively arranged close to corresponding antenna positions, so as to reduce insertion loss of wires between the first transceiver circuit 220 and the first antenna group 240 and insertion loss of wires between the second transceiver circuit 230 and the second antenna group 250, thereby improving the emission performance of the electronic device.

With continued reference to fig. 3, in one embodiment, the first antenna set includes a first antenna ANT0 and a second antenna ANT1, and the second antenna set includes a third antenna ANT2 and a fourth antenna ANT 3. That is, the first transceiving circuit 220 may be switchably connected to the first antenna ANT0 and the second antenna ANT1, that is, the first transmission signal may be switchably transmitted between the first antenna ANT0 and the second antenna ANT 1. The second transceiving circuit 230 may be switchably connected to the third antenna ANT2 and the fourth antenna ANT3, that is, the second transmission signal may be switchably transmitted between the third antenna ANT2 and the fourth antenna ANT 3.

In one embodiment, the first antenna group includes a second antenna ANT1 and a third antenna ANT2, and the second antenna group includes the first antenna ANT0 and the fourth antenna ANT 3. That is, the first transceiving circuit 220 may be switchably connected to the first antenna ANT0 and the fourth antenna ANT3, and the second transceiving circuit 230 may be switchably connected to the first antenna ANT0 and the fourth antenna ANT 3.

It should be noted that the division of the first antenna group 240 and the second antenna group 250 is not limited to the above-mentioned example, and may also be in other combination forms, for example, the first antenna group 240 includes the first antenna ANT0 and the third antenna ANT2, the second antenna group 250 includes the second antenna ANT1 and the fourth antenna ANT3, or the first antenna group 240 includes the first antenna ANT0 and the fourth antenna ANT3, the second antenna group 250 includes the second antenna ANT1 and the third antenna ANT2, and so on, and the first antenna group 240 and the second antenna group 250 may be divided according to actual requirements in the embodiments of the present application.

With reference to fig. 2, based on any of the foregoing embodiments, the electronic device further includes a circuit board 13, wherein the first transceiver circuit 220 and the second transceiver circuit 230 are both disposed on the circuit board 13, and the first transceiver circuit 220 is disposed near the third antenna ANT 2; the second transceiving circuit 230 is disposed near the first antenna ANT0 and the fourth antenna ANT 3.

In the embodiment of the present application, since the first transceiver circuit 220 and the second transceiver circuit 230 are independent from each other, the first side frame 125 of the first transceiver circuit 220 may be disposed, for example, near the third frame and near the bottom frame 123; the second transceiver circuit 230 is disposed close to the bottom frame 123 and the second side frame, so that the insertion loss of the antenna and the transceiver circuit can be reduced, and the communication performance of the electronic device can be further improved.

In addition, when the first antenna group 240 includes the second antenna ANT1 and the third antenna ANT2, the second antenna group 250 includes the first antenna ANT0 and the fourth antenna ANT 3. That is, the first transceiver circuit 220 is switchably connected to the second antenna ANT1 and the third antenna ANT2, and the second transceiver circuit 230 is switchably connected to the first antenna ANT0 and the fourth antenna ANT3, so that the length of the wires between the transceiver circuit and each antenna is further shortened, and the insertion loss of the wires is reduced.

With continued reference to fig. 2, in one embodiment, the third antenna ANT2 is formed in the middle area of the first side frame 125. The fourth antenna ANT3 may be formed in the middle of the second side frame 127. It should be noted that the middle area may be understood as a non-holding area (i.e., an area not held by a user) on the side frame when the electronic device is held in a landscape mode. Illustratively, the length of the middle region of the side frame may be 3/1-2/3 of the total length of the side frame, and the middle region is disposed away from the top frame 121 and the bottom frame 123, respectively.

In the embodiment of the present application, the third antenna ANT2 or/and the fourth antenna ANT3 are/is disposed in the middle area of the side frame, so that when a user holds the electronic device in a landscape screen, the antenna formed on the side frame of the user is not shielded, and the antenna radiation performance of the electronic device in a landscape screen holding state can be further improved.

Based on the electronic device shown in fig. 2 and fig. 3 and the electronic device of the related art (the radio frequency signal is switched only between the first antenna and the second antenna), taking the radio frequency signal as LTE B3 as an example, simulation is performed, and antenna performance of switching of radio frequency between different antennas can be obtained.

TABLE 1 antenna Performance for RF signal switching between a first antenna and a second antenna in the related art

LTE B3	ANT0	ANT1	ANT2	ANT3
					Conductivity of	24	24	Do not support	Do not support
Free space efficiency	-3.5	-4
					Horizontal screen holding reduced amplitude	-10	-10
Transverse screen holding transmitting power	10.5	10

Table 2 shows the antenna performance of the RF signal switching among four antennas in the embodiment of the present application

LTE B3	ANT0	ANT1	ANT2	ANT3
					Conductivity of	24	24	23	22
Free space efficiency	-3.5	-4	-6.5	-6
					Horizontal screen holding reduced amplitude	-10	-10	-8	-1
Transverse screen holding transmitting power	10.5	10	8.5	13

In table 1 and table 2, the horizontal screen holding amplitude reduction is a difference between the antenna free space efficiency and the efficiency of the electronic device when holding the horizontal screen, and the horizontal screen holding emission Power is Total Radiated Power (TRP) held by the horizontal screen, which can reflect the emission Power of the whole electronic device and is related to the emission Power of the electronic device under the conduction condition and the antenna radiation performance. As can be seen from comparison between table 1 and table 2, in the electronic device in the embodiment of the present application, although the conductivity of the third antenna ANT2 may be reduced by about 2dB and the antenna free space performance of the third antenna ANT2 may be slightly inferior to that of the first antenna ANT0 and the second antenna ANT1 in the landscape screen holding state, compared with the electronic device in the related art, the total radiation power TRP may be increased by about 4.5dB to 5dB as compared with that of the first antenna ANT0 and the second antenna ANT 1. Therefore, the electronic equipment provided by the embodiment of the application can improve the emission performance of the electronic equipment even in a horizontal screen holding state.

As shown in fig. 4-6, in one embodiment, the first transceiver circuit 220 includes a first transceiver module 221 and a first switch unit 223, where the first switch unit 223 is respectively connected to the first transceiver module 221 and the first antenna set 240, and is configured to switchably connect the first transceiver module 221 to two antennas in the first antenna set 240. The second transceiver circuit 230 includes a second transceiver module 231 and a second switch unit 233, where the second switch unit 233 is respectively connected to the second transceiver module 231 and the second antenna group 250, and is configured to switchably connect the second transceiver module 231 to two antennas in the second antenna group 250.

The first transceiver module 221 is connected to the rf transceiver 210, and configured to transceive the first rf signal; the second transceiving module 231 is connected to the rf transceiver 210 for transceiving the second rf signal. Specifically, the first transceiver module 221 and the second transceiver module 231 may be rf PA Mid devices. The rf PA Mid device may be understood as a Power Amplifier module (PA Mid) with a built-in low noise Amplifier, which may be used to support the amplification and filtering processing of rf signals in multiple different frequency bands. It should be noted that, in the embodiment of the present application, specific composition forms of the first transceiver module 221 and the second transceiver module 231 are not further limited. For example, the first transceiver module 221 may be an LTE transceiver module for supporting transceiving processing of 4G LTE signals of multiple frequency bands, and the second transceiver module 231 may be an NR transceiver module for supporting transceiving processing of 5G NR signals of multiple frequency bands.

It should be noted that, in this embodiment, the first transceiver module 221 and the second transceiver module 231 may also be transceiver modules for supporting other frequency bands besides the 4G LTE and 5G NR frequency bands, which is not specifically limited in this embodiment.

Specifically, the first and

second switching units

223 and 233 may be single pole double throw switches. The first transceiver module may switch the first switch unit 223 to connect to the two antennas of the first antenna set 240, that is, transmit the first rf signal to the two antennas of the first antenna set 240 through the first switch unit 223 for transmission; the second transceiver module 231 can switch the two antennas connected to the second antenna set 250 through the second switch unit 233, that is, transmit the second radio frequency signal to the two antennas of the second antenna set 250 through the second switch unit 233 for transmission.

Even if the electronic device is held by a landscape screen (the first antenna ANT0 and the second antenna ANT1 are both shielded), by providing the first switch unit 223 and the second switch unit 233, the first transceiver module 221 and the second transceiver module 231 may be connected to the third antenna ANT2 and the fourth antenna ANT3 provided on the side frames through the first switch unit 223 and the second switch unit 233, respectively, and perform transmission or main set reception of radio frequency signals through the third antenna ANT2 and the fourth antenna ANT3 provided on both side frames (i.e., the side frames that are not shielded), so as to improve the transmission performance of the antennas. In addition, the two single-pole double-throw switches are used for realizing the alternate transmission function of the radio frequency signals among the 4 antennas, the 3P4T switch or the 4P4T switch is not used, the loss of a transmission path can be reduced, and the transmission performance of the electronic equipment is improved.

The operation principle of the antenna device in the NSA operation mode and the SA operation mode is explained based on the electronic device as shown in fig. 12. Specifically, when the radio transceiver 210 needs to operate in the NSA operation mode, the radio transceiver 210 may provide the first uhf signal to the first transceiving unit 281 and the second transceiving unit 283 in a time-sharing manner, and control the on state of the radio frequency switch in the first transceiving unit 281, so as to implement switching of the first uhf signal between the first antenna ANT0 and the third antenna ANT2, and control the on state of the third switching unit 290, so as to implement switching of the first uhf signal between the fourth antenna ANT3 and the fifth antenna ANT4, and further implement SRS function of the first uhf signal between the four antennas, i.e., the first antenna ANT0, the third antenna ANT2, the fourth antenna ANT3, and the fifth antenna ANT4, of 1T 4R. When it is required to operate in the NSA operation mode, the rf transceiver 210 simultaneously provides the first uhf signal to the first transceiver unit 281 and the second transceiver unit 283, so that the SRS function of the first uhf signal 2T4R can be realized among the four antennas, i.e., the first antenna ANT0, the third antenna ANT2, the fourth antenna ANT3, and the fifth antenna ANT 4.

In addition, since the second uhf signal has a lower frequency in actual use, in the electronic device in this embodiment, the second uhf signal may also be supported to be alternately transmitted between the first antenna ANT0 and the third antenna ANT2, so as to support the SRS function of 1T 42.

In this embodiment, the fifth antenna ANT4 is disposed on the bottom frame and adjacent to the first antenna ANT0, and in addition, the first transceiver unit 281 is disposed close to the first antenna ANT0 and the third antenna ANT2, and the second transceiver module is disposed close to the fourth antenna ANT3 and the fifth antenna ANT4, so that the layout and the wiring can be facilitated, the length of the wire between the third transceiver module 280 and each antenna can be shortened, and the insertion loss of the wire can be reduced, thereby providing the communication performance of the electronic device for transmitting the uhf signal. Meanwhile, because the ultrahigh frequency signal can be transmitted by switching among the first antenna ANT0, the third antenna ANT2, the fourth antenna ANT3 and the fifth antenna ANT4, even if the electronic device is held by the landscape screen, the third antenna ANT2 and the fourth antenna ANT3 are not shielded, and the communication performance of the electronic device when held by the landscape screen can be improved.
