[0017] The RF connection unit 1 includes a connection base 11 combined with the mounting module 91 and having a receiving space 111, and a RF connection module 12 located in the receiving space 111 of the connection base 11. The housing 2 is pivotally connected to the connection base 11 of the RF connection unit 1, and includes a top plate 21 away from the connection base 11. The top plate 21 and the connection base 11 are located at two opposite ends of the housing 2.
[0018] The first antenna unit 3 includes a first coaxial line module 31 connected to the RF connection module 12, and a first antenna module 32 connected to the first coaxial line module 31 and extending from the first coaxial line module 31 toward the top plate 21 of the housing 2. In this embodiment, the default position of the first antenna module 32 is to be fixedly connected to the first coaxial line module 31 and located inside the housing 2, but the present invention is not limited thereto.
[0019] The second antenna unit 4 includes a second coaxial line module 41 located inside the housing 2 and connected to the RF connection module 12, extending toward the top plate 21 of the housing 2 and penetrating the top plate 21, and a second antenna module 42 located outside the housing 2 and detachably connected to the second coaxial line module 41, and extending from the second coaxial line module 41 toward a direction away from the top plate 21. The second coaxial line module 41 and the first antenna unit 3 are parallel and spaced apart from each other.
[0020] During assembly, the connection base 11 of the RF connection unit 1 is first connected to the installation module 91 of the electronic device 90, and the RF connection module 12 of the RF connection unit 1 is electrically connected to the installation module 91, so that the first coaxial line module 31 of the first antenna unit 3 and the second coaxial line module 41 of the second antenna unit 4 can be electrically connected to the electronic device 90 through the RF connection module 12. Finally, since the second coaxial line module 41 passes through the top plate 21 and can be connected to the second antenna module 42, it is only necessary to connect the second antenna module 42 of the second antenna unit 4 to the second coaxial line module 41, and make the second antenna module 42 as shown in the figure. Figure 2 , 3 As shown, the second coaxial line module 41 is directly connected in series above the top plate 21 to form an electrical connection to complete the assembly operation. In other words, once the RF connection unit 1 is connected to the mounting module 91, the electronic device 90 is electrically connected to the RF connection module 12 through the mounting module 91 and the first coaxial line module 31 and the second coaxial line module 41 are connected through the RF connection module 12, so that the electronic device 90 can use the first antenna module 32 and the second antenna module 42 for ultra-high-speed wireless transmission and antenna doubling applications.
[0021] The RF connection module 12 of the RF connection unit 1 can be designed to simultaneously connect the first coaxial line module 31 of the first antenna unit 3 to form an electrical connection and the second coaxial line module 41 of the second antenna unit 4 to form an electrical connection, and the second coaxial line module 41 is used to penetrate the top plate 21 so as to be connected to the second antenna module 42, so that the RF connection module 12 can be externally connected to the first antenna unit 3 and the second antenna unit 4, and the electronic device 90 can be connected to the RF connection module 12 through a single installation module 91 to externally connect the first antenna unit 3 and the second antenna unit 4, so as to meet the antenna multiplication requirements and facilitate the purpose of ultra-high-speed wireless transmission. Furthermore, through the ingenuity of the second coaxial line module 41 of the second antenna unit 4 penetrating the top plate 21, it is convenient to directly connect the second antenna module 42 in series above the top plate 21, which is easy to assemble and has good applicability.
[0022] Here, it should be particularly noted that, in this embodiment, the RF connection module 12 of the RF connection unit 1 has a first terminal 121 connected to the first coaxial line module 31, and a second terminal 122 connected to the second coaxial line module 41. The first antenna module 32 of the first antenna unit 3 has a first spiral wire member 321 connected to the first coaxial line module 31, and a first wire member 322 extending from the first spiral wire member 321 to the top plate 21 of the housing 2. The first wire member 322 is a non-spiral shape, but is not limited to this. The second coaxial line module 41 of the second antenna unit 4 has a coaxial connector 411 that penetrates the top plate 21 of the housing 2. The second antenna module 42 has a second spiral wire member 421 connected to the coaxial connector 411 of the second coaxial line module 41 and extending from the coaxial connector 411 to the direction away from the top plate 21, and a second wire member 422 extending from the second spiral wire member 421 to the direction away from the top plate 21. The second conductor module 422 is in a non-spiral shape, but is not limited thereto. The connection base 11 of the RF connection unit 1 is combined with the mounting module 91 and the first terminal 121 and the second terminal 122 of the RF connection module 12 are electrically connected to the mounting module 91. That is, the RF connection module 12 of the RF connection unit 1 is electrically connected to the mounting module 91 through the first terminal 121 and the second terminal 122, thereby making the first coaxial line module 31 of the first antenna unit 3 electrically connected to the electronic device 90 through the first terminal 121 and the mounting module 91, and the second coaxial line module 41 of the second antenna unit 4 is electrically connected to the electronic device 90 through the second terminal 122 and the mounting module 91. By the way, in the present embodiment, the RF connection module 12 of the RF connection unit 1 is designed with two connection terminal patterns through the first terminal 121 and the second terminal 122, so that the first coaxial line module 31 of the first antenna unit 3 and the second coaxial line module 41 of the second antenna unit 4 can be connected. However, this is not limited to the above. According to actual needs, the RF connection module 12 of the RF connection unit 1 can be designed to have three connection terminal patterns or more than three connection terminal patterns, so that multiple coaxial line module patterns can be connected, thereby meeting the use requirements of supporting the connection of three or more antenna unit patterns.

If the length design of the first linear metal wire of the first wire member 322 of the first antenna module 32 of the first antenna unit 3 can meet the required center frequency, there is no need to additionally design the structure of the first spiral wire member 321, or the second linear metal wire of the second wire member 422 of the second antenna module 42 of the second antenna unit 4 can meet the required center frequency, there is no need to additionally design the structure of the second spiral wire member 421.
[0024] In addition, in this embodiment, the coaxial connector 411 of the second coaxial line module 41 of the second antenna unit 4 is in the form of an SMA connector, but it is not limited thereto, and an SMB connector may also be used, as long as it is a low-loss RF connector.
