[0035] The present application provides a wireless device 100, such as Figure 1 As shown, including:

[0036] The housing 1 can be divided into a bottom shell 10 and an upper cover 11 , and a receiving cavity 12 is formed in the housing 1 ;

[0037] A circuit board 2 is disposed within the housing 10. A radio frequency chip 20, at least two branching units 21, and an antenna 22 are disposed on the circuit board 2. A circuit pattern may be formed on the circuit board 2, and the circuit pattern may include a signal line, a ground line, and a power line. The antenna 22 may be electrically connected to the circuit board 2 via a cable or connector and extend to the outside of the housing 1, or may be disposed inside the housing 1 and attached to the inner wall of the housing 1.

[0038] The radio frequency chip 20, the branch unit 21 and the antenna 22 are electrically connected in sequence. Other devices may also be provided in the wireless device 100, such as a processor for processing data, which may be connected to the radio frequency chip 20;

[0039] At least two first RF signals are provided on the RF chip 20 . Each first RF signal is converted into two branch signals through the branch unit 21 . Each branch signal is connected to a corresponding antenna 22 .

[0040] like Figure 2 As shown, two first RF signals are formed on the RF chip 20, and one first RF signal includes a receiving signal and a transmitting signal, corresponding to the transmitting end and the receiving end on the RF chip 20, and due to the setting of at least two first RF signals, the RF chip 20 includes at least two transmitting ends TX0, TX1 and two receiving ends RX0, RX1.

[0041] Among them, the transmitting end TX0 and the receiving end RX0 belong to the first path of the first RF signal, and are respectively connected to the same branch unit 21 to form branch transmitting ends TX00, TX01 and branch receiving ends RX00, RX01. The branch transmitting end TX00 and the branch receiving end RX00 form a first branch signal, and the branch transmitting end TX01 and the branch receiving end RX01 form a second branch signal. The transmitting end TX1 and the receiving end RX1 belong to the second path of the first RF signal, and are respectively connected to another branch unit 21 to form a branch transmitting end TX10, TX11 and branch receiving ends RX10, RX11. The branch transmitting end TX10 and the branch receiving end RX10 form a third branch signal, and the branch transmitting end TX11 and the branch receiving end RX11 form a fourth branch signal.

[0042] It should be noted that the wireless device 100 can generate more RF signals and more branch signals, which can be configured according to actual needs without limitation.

[0043] against Figure 2 In the illustrated embodiment, four antennas 22, namely antennas 22A, 22B, 22C, and 22D, can be provided on the circuit board 2. The first branch signal is connected to antenna 22A, the second branch signal is connected to antenna 22B, the third branch signal is connected to antenna 22C, and the fourth branch signal is connected to antenna 22D. In other words, a first RF signal can be split into two identical branch signals by the branching unit 21. The identical branch signals are then connected to different antennas 22 for transmission, thereby forming enhanced signal coverage in the direction in which the antennas 22 are provided, thereby improving the wireless signal coverage of the wireless device.

[0044] As described above, optionally, there are at least four antennas 22 , wherein every two antennas 22 correspond to two branched signals formed by one first RF signal passing through the branching unit 21 .

[0045] In some cases, RF signals of different frequencies can be set on the RF chip 20 according to needs. Optionally, a second RF signal is also set on the RF chip 20, and the receiving end and the transmitting end of the second RF signal are connected to an antenna 22, wherein the first RF signal and the second RF signal are RF signals of different frequencies.

[0046] For example, the wireless device 100 may be provided with a 2.4 GHz radio frequency signal and a 5 GHz radio frequency signal, wherein the first radio frequency signal is split, while the second radio frequency signal is not split, and the two first radio frequency signals and the second radio frequency signal may be transmitted and received via at least five antennas 22. Of course, the second radio frequency signal may also be provided with two transmitting ends and two receiving ends, and connected to two antennas 22, that is, a total of six antennas 22 may be used to transmit and receive the two first radio frequency signals and the second radio frequency signal. This configuration may be based on actual needs and is not limited thereto.

[0047] During the branching process, the signal strength of the radio frequency signal will be attenuated and cannot meet the needs of signal transmission and reception. Optionally, the branching unit 21, such as Figure 2 As shown, including:

[0048] At least two power splitters 210, one power splitter 210A is connected to the receiving end RX0 of the first RF signal to form branch receiving ends RX00 and RX01, and the other power splitter 220B is connected to the transmitting end TX0 of the first RF signal to form branch transmitting ends TX00 and TX01;

[0049] There are at least two amplifiers 211 , one amplifier 211 is connected to a branch transmitting end of a branch signal and a branch receiving end of the branch signal, and one amplifier 211 is connected to an antenna 22 .

[0050] For example, the branch transmitting terminal TX00 and the branch receiving terminal RX00 are connected to the amplifier 211A, the amplifier 211A is connected to the antenna 22A, the branch transmitting terminal TX01 and the branch receiving terminal RX01 are connected to the amplifier 211B, the amplifier 211B is connected to the antenna 22B, the branch transmitting terminal TX10 and the branch receiving terminal RX10 are connected to the amplifier 221C, the amplifier 221C is connected to the antenna 22C, the branch transmitting terminal TX11 and the branch receiving terminal RX11 are connected to the amplifier 211D, and the amplifier 211D is connected to the antenna 22D.

[0051] In order to achieve vertical signal coverage of the antenna 22 in a duplex or other house, optionally, the first antennas 22A and 22C connected to the branch signal corresponding to one first RF signal are arranged vertically, and the second antennas 22B and 22D connected to the branch signal corresponding to another first RF signal are arranged horizontally.

[0052] By setting the branch signal in the horizontal and vertical directions respectively, the coverage of the radio frequency signal can be extended vertically and horizontally respectively, so that the signal coverage of the wireless device 100 can be nearly spherical, meeting the vertical and horizontal coverage of the wireless signal for the duplex house.

[0053] Optionally, the first antennas 22A and 22C and the second antennas 22B and 22D are arranged outside the housing 1 .

[0054] The first antenna 22A, 22C and the second antenna 22B, 22D may be disposed outside the housing 1 in a manner that is not limited according to actual needs.

[0055] Further, such as Figure 3 As shown, the housing 1 is cylindrical;

[0056] The first antennas 22A and 22C are disposed on the circular surface 1A of the housing 1 , and the second antennas 22B and 22D are disposed on the cylindrical surface 1B of the housing 1 .

[0057] Furthermore, the wireless device 100 further includes:

[0058] The fixing bracket 4 clamps the cylindrical surface 1B of the housing 1 . The fixing bracket 4 allows the wireless device 100 to be suspended in the air, thereby making the arrangement of the antenna 22 more flexible.

[0059] Optional, such as Figure 4 As shown, the first antennas 22A, 22C and the second antennas 22B, 22D are arranged inside the housing 1 .

[0060] Furthermore, the housing 1 is rectangular;

[0061] The first antennas 22A and 22C connected to the branched signals corresponding to one first radio frequency signal are vertically arranged on the vertical inner wall 11A of the housing 1;

[0062] The second antennas 22B and 22D connected to the branch signal corresponding to the other first RF signal are arranged horizontally on the horizontal inner wall 11B of the housing 1. For example, the vertical inner wall 11A and the horizontal inner wall 11B are the inner walls of the upper cover 11. Figure 4 The dotted line indicates that the antenna 22 is arranged inside the housing 1.

[0063] That is, the antenna 22 of the wireless device 100 is housed inside the housing 1, and there is no need to extend the antenna 22 to the outside of the housing 1, so that the wireless device 100 can have better appearance consistency, so that the wireless device 100 can be placed on a platform or other location, thereby improving the placement flexibility of the wireless device.

[0064] exist Figure 3 、 4 In the structures of the two wireless devices 100, the first RF signal is divided into two branch signals, and the signal coverage is provided to the outside through four antennas 22. However, the structure is not limited to the illustrated structure. For example, the wireless device 100 may also include a second RF signal at a different frequency from the first RF signal, that is, the second RF signal can be sent and received by setting at least one additional antenna 22.

[0065] In addition, the antenna 22 is provided inside the wireless device 100, so that the position of the antenna 22 is more reliable and less susceptible to external impact, thereby improving the stability of the wireless signal coverage of the wireless device.

[0066] The technical solutions provided by the embodiments of this specification may have the following beneficial effects:

[0067] In the embodiments of this specification, in a wireless device, the RF signal of the RF chip is branched by a branching unit, converting one RF signal into two branch signals, each of which is connected to a different antenna, thereby expanding the wireless signal coverage of the wireless device and improving the communication reliability of the wireless device.
