The implementation of the remaining antennas in the first group of antennas is similar, and the description of the present application is omitted here.

Referring to fig. 4, the figure is a schematic diagram of the antenna provided in the embodiment of the present application when connected to the first circuit board.

Referring to fig. 5, the figure is a schematic view of the antenna provided in the embodiment of the present application when connected to the second circuit board.

Only a partial region of the first circuit board 31 is shown in fig. 5, and the remaining region is not shown.

The antenna 21 includes a first connection portion 211, and the first connection portion 211 is connected to a corresponding second connection portion 321 on the second circuit board 32. The second connecting portion 321 connects the circuit board traces 312 on the second circuit board 32.

In a possible implementation manner, in fig. 5, the first connection portion 211 is a metal elastic sheet, the second connection portion 321 is a metal base, and the metal elastic sheet and the metal base are pressed together by using an elastic force.

For the plurality of second circuit boards 32 included in the terminal device, the number of antennas connected to each second circuit board 32 is not particularly limited in the embodiment of the present application, where there may be a second circuit board 32 to which a plurality of antennas are simultaneously connected, or there may be a second circuit board 32 to which no antenna is connected.

Compared with the scheme that all antennas are connected with the main circuit board through the connecting lines at present, the scheme provided by the embodiment of the application reduces the number of the used connecting lines. Specifically, the number of the reduced connecting lines is the number of the first group of antennas, that is, the larger the number of the first group of antennas is, the larger the number of the reduced connecting lines is. Because the quantity of connecting wires is reduced, the whole machine assembling and processing difficulty of the terminal equipment is reduced, the probability of falling off and poor contact of the connecting wires is also reduced, and the reliability and the stability of the communication function of the terminal equipment are further improved.

With continued reference to fig. 2, a first set of antennas and a first circuit board 31 are located in a first area of the terminal device and a second set of antennas and respective second circuit boards 32 are located in a second area of the terminal device.

A cable can be plugged into the interface 40, and the cable can be connected with an external power supply to charge the terminal equipment; the cable may also connect other devices to enable data transmission between the terminal device and the other devices.

The type of the interface 40 may be a Lightning (Lightning) interface or a Universal Serial Bus (USB) interface, etc. When the interface 40 is a USB interface, it may be specifically a Mini USB interface, a Micro USB interface, or a USB Type C interface, which is not specifically limited in this embodiment of the application.

The first set of interfaces is located in the first zone and the second set of interfaces is located in the second zone. I.e. the first set of interfaces and the second set of interfaces are located on opposite sides of the terminal device.

The first circuit board 31 is disposed on a side away from the interface, and is less subject to layout constraints, and the first circuit board 31 may serve as a main circuit board of the terminal device.

In some embodiments, when the first circuit board 31 is used as a main circuit board, the number of components arranged thereon is larger, and therefore the area of the first circuit board 31 is generally larger than that of the second circuit board 32.

A Cellular network (Cellular network) radio frequency chip, a satellite positioning and navigation chip, a baseband chip and a Wi-Fi chip may be disposed on the first circuit board 31.

The controller can generate an operation control signal according to the instruction operation code and the timing signal to complete the control of instruction fetching and instruction execution.

A memory may also be provided in the processor for storing instructions and data. In some embodiments, the memory in the processor is a cache memory. The memory may hold instructions or data that have just been used or recycled by the processor. If the processor needs to use the instruction or data again, it can be called directly from the memory. Avoiding repeated accesses reduces the latency of the processor and thus increases the efficiency of the system.

The plurality of second circuit boards are disposed on a side close to the interface 40, and at this time, the plurality of second circuit boards may be arranged according to the positions of the interface 40 and other functional modules, so as to fully utilize the space. For example, when the plurality of second circuit boards are disposed in the second area, the position of the interface 40, the battery, and the Subscriber Identity Module (SIM) card slot need to be considered.

The second group of antennas includes a second group of cellular antennas, and the second group of cellular antennas includes cellular antennas of different frequency bands, for example, MHB cellular antennas, MHB multiple-input multiple-output (MIMO) cellular antennas, LB cellular antennas, n78 frequency band cellular antennas, n79 frequency band cellular antennas, and so on.

The side where the first area is located comprises a first group of antenna seams, wherein; the side on which the second region is located includes a second set of antenna seams.

Specifically, the first set of antenna seams includes antenna seams 51, 53, 54, and 57; the second set of antenna slots includes

antenna slots

52, 55, 56, and 58.

Antennas in terminal devices may be used to cover single or multiple communications bands. The antenna can also be multiplexed to improve the utilization rate of the antenna. For example: the cellular antennas may be multiplexed into diversity antennas of the wireless local area network.

In some embodiments, when a user holds a terminal device, shielding of the user's hand on an antenna may reduce signal quality of the antenna, and in order to ensure signal quality of the terminal device in different holding states, generally, wires of the terminal device are dispersedly distributed at an upper end and a lower end, and antennas for transceiving signals in the same frequency band may be redundantly arranged and distributed at two opposite sides of the terminal device, for example, two cellular antennas supporting the same frequency band may be arranged, one of the two cellular antennas is located at the upper end, i.e., a first region, of the terminal device, and the other one is located at the lower end, i.e., a second region, of the terminal device.

The functions of the antennas are described in detail below, and the following description is only one possible arrangement of the antennas, and the antennas may also adopt other arrangements.

The top of the terminal equipment comprises 6 antennas, namely from the antenna 11 to the antenna 16, and the functions are respectively as follows:

antenna 11: the cellular antenna integrates the n41(2.496GHz-2.690GHz) frequency band, the n78(3.3GHz-3.8GHz) frequency band and the n79(4.4GHz-5GHz) frequency band.

The antenna 12: low Band (LB) cellular antennas.

Antenna 13: the cellular antenna has the advantages of meeting the requirements of both a Middle and High frequency band (MHB) (1.71GHz-2.7GHz) and an n79 frequency band.

Antenna 14: the antenna has both the n78 frequency band and the Wi-Fi 5GHz frequency band.

Antenna 15: and the antenna has both Wi-Fi 2.4GHz frequency band and satellite positioning and navigation functions.

The antenna 16: a dual-band MIMO antenna with Wi-Fi 2.4GHz band and Wi-Fi 5GHz band.

Wherein the

antennas

11, 12 and 13 are laid out at the upper left position of the terminal device and the

antennas

14, 15 and 16 are laid out at the upper right position of the terminal device.

Since the 6 antennas included in the first group of antennas are directly connected to the first circuit board, the terminal equipment reduces the use of 6 connecting wires.

In some embodiments, antennas 12 are a main set of antennas and antennas 13 are diversity antennas.

The bottom of the terminal equipment comprises 5 antennas, namely 21 to 25, and the functions are as follows:

antenna 21: the MIMO cellular antenna gives consideration to the n79 frequency band and the MHB frequency band.

Antenna 22: the MIMO cellular antenna gives consideration to the n78 frequency band and the MHB frequency band.

Antenna 23: the cellular antenna has both the n78 frequency band and the n79 frequency band.

Antenna 24: low Band (LB) cellular antennas.

Antenna 25: cellular antenna in MHB band.

In some embodiments, antennas 25 are a main set of antennas, with the remaining antennas being diversity antennas.

Further, in order to ensure the signal strength of the terminal device in different holding states, a switch may be used on the circuit to implement switching between the main set antenna, the diversity antenna, and the MIMO antenna, which is described in detail below with reference to the accompanying drawings.

With reference to fig. 13, when the terminal device is in a holding state of a vertical screen, for the antenna seam 50 on the lower right side, when the right hand of the user moves downward according to the arrow shown in the figure, the antenna seam 50 may be blocked, and the quality of the signal transmitted by the antenna 25 to the outside may be affected.

At this time, the terminal device switches the transmitting antenna to the antenna 13 compatible with the MHB band by using the switch, that is, the switching between the main current collecting wire and the diversity antenna is realized. Since the antenna 13 is not shielded at this time, the quality of the externally transmitted signal of the antenna 13 is not affected.
