[0025] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention. The PCB in this article refers to a circuit board.
[0026] like Figure 1 and Figure 3 As shown, the preferred embodiment of the utility model provides a composite rubber stick antenna, which includes a shell 1, a first antenna 2 and a second antenna 3. The inner wall of the accommodating cavity 11 is provided with a first limiting groove 12 and a second limiting groove 13 extending in the direction of the opening of the accommodating cavity 11. The first limiting groove 12 is arranged in parallel with the second limiting groove 13. The first antenna 2 is arranged in the first limiting groove 12 and fixedly connected to the shell 1, and the second antenna 3 is arranged in the second limiting groove 13 and fixedly connected to the shell 1.
[0027] The housing 1 is equipped with a base 4 at the opening of the accommodating cavity 11 , and the base 4 is used to abut and limit the first antenna 2 and the second antenna 3 .
[0028] Specifically, in the traditional antenna field, in order to ensure the stability of network connection and smooth switching and achieve high-quality network connection, multiple wireless communication antennas are often set up, and the antennas of each wireless communication technology are designed separately, which not only makes the design cost and production cost higher, but also makes the device more bulky. In the present utility model, the first antenna 2 and the second antenna 3 are integrated into a housing 1, and are fixed by the first limiting groove 12 and the second limiting groove 13 respectively, so that the size of the device is smaller, only one housing 1 is needed, and there is no need to set up multiple antenna housings, which is obviously lower in design cost and production cost. Furthermore, the first limiting groove 12 and the second limiting groove 13 in the accommodating cavity 11 both extend toward the opening direction of the accommodating cavity 11 and are arranged in parallel, and the first antenna 2 and the second antenna 3 are respectively restricted and fixed by the first limiting groove 12 and the second limiting groove 13, and the first antenna 2 and the second antenna 3 are also arranged in parallel and perpendicular to the plane at the opening of the accommodating cavity 11, which makes the first antenna 2 and the second antenna 3 not only have a larger installation space in the length direction, but also can better design and install the antenna structure, and due to the parallel arrangement of the first antenna 2 and the second antenna 3, it can also avoid the problem that the two antennas are too close at one end due to tilting, and then affect each other. The parallel arrangement of the two antennas can better ensure the isolation between the antennas of the two frequency bands, minimize interference, and thus improve communication quality and communication stability.
[0029] In addition, during the actual installation and use process, after the first antenna 2 and the second antenna 3 are respectively inserted into the first limiting groove 12 and the second limiting groove 13, the base 4 is assembled at the opening of the accommodating cavity 11. The base 4 is used to close the opening of the accommodating cavity 11 and abut to limit the first antenna 2 and the second antenna 3 in the accommodating cavity 11 to prevent the first antenna 2 and the second antenna 3 from slipping out of the accommodating cavity 11.
[0030] In some embodiments, the working frequency band of the first antenna 2 is the 2.4G frequency band, and the working frequency band of the second antenna 3 is the LTE frequency band. The setting of these two working frequency band antennas can adapt to more communication environments and communication requirements, ensure the stability and efficiency of the communication process, and enable the wireless communication device to smoothly switch between the two working frequency bands, ensuring that the best network experience is always provided.
[0031] like Figure 3As shown, in some embodiments, two first limiting grooves 12 and two second limiting grooves 13 are symmetrically arranged in the accommodating cavity 11 along the axis of the housing 1. Specifically, the two symmetrically arranged first limiting grooves 12 can limit the two sides of the first antenna 2, so that the position of the first antenna 2 in the accommodating cavity 11 is more stable, and the antenna body will not shake due to external impact and other factors, thereby avoiding the problem of deformation and mutual collision of the two antennas in the accommodating cavity 11 due to shaking, thereby ensuring the stability and reliability of communication quality.
[0032] In some embodiments, the first antenna 2 includes a first PCB board 21 and a first PCB trace 22 disposed on the first PCB board 21 , and the second antenna 3 includes a second PCB board 31 and a second PCB trace 32 disposed on the second PCB board 31 .
[0033] The first PCB board 21 and the second PCB board 31 are both rigid PCB boards. The first PCB board 21 is clamped in the first limiting groove 12 , and the second PCB board 31 is clamped in the second limiting groove 13 .
[0034] Specifically, among the types of antennas, there are wire antennas, PCB antennas and chip antennas, wherein the wire antenna includes a wire extending from the PCB to the free space, its length is λ / 4, and it is placed on the ground layer; while the PCB antenna includes a PCB trace arranged on the PCB board, and it can be drawn as a straight trace, an inverted F-shaped trace, a serpentine or circular trace, or a swing curve based on the antenna type and space restrictions, etc.; in a PCB antenna, the antenna becomes a two-dimensional structure on the same plane of the PCB. In this embodiment, the first antenna 2 and the second antenna 3 are both PCB antennas, both include a PCB board and a PCB trace arranged on the board, and both use a rigid PCB board, which has a lower production cost and is easier to manufacture, and on the other hand, it is also convenient to fix the first antenna 2 and the second antenna 3 in the first limit groove 12 and the second limit groove 13 respectively, and the PCB board can be directly inserted into the corresponding limit groove, and the installation process is also simpler and more convenient.
[0035] In some embodiments, the first PCB trace 22 is disposed at an end of the first PCB board 21 close to the base 4 , and the second PCB trace 32 is disposed at an end of the second PCB board 31 away from the base 4 .
[0036] Specifically, while keeping the first antenna 2 and the second antenna 3 parallel, the distance between the two antennas in the horizontal direction can be guaranteed. On this basis, the PCB traces on the first antenna 2 and the PCB traces on the second antenna 3 are respectively arranged at the two ends of the accommodating cavity 11, and the distance is also kept in the vertical direction to ensure the isolation between the two antennas, thereby maximizing the radiation efficiency of the antennas in the two frequency bands when working.
[0037] In some embodiments, a limiting clamping plate 41 disposed in the accommodating cavity 11 is symmetrically fixed to the top surface of the base 4 , a clamping block 411 is disposed on the side wall of the limiting clamping plate 41 , and a clamping groove 14 is disposed on the inner wall of the accommodating cavity 11 corresponding to the clamping block 411 .
[0038] Specifically, two blocks 411 are arranged horizontally in parallel on a single limiting card plate 41, and a total of four card slots 14 are arranged on the inner wall of the accommodating cavity 11, which can better and more stably assemble the base 4 and the shell 1 together; in some other embodiments, the card slot 14 can also be arranged on the outer wall of the shell 1.
[0039] In some embodiments, a limiting rib 412 is provided on one side of the limiting card plate 41 away from the card block 411, and the limiting rib 412 abuts against the first PCB board 21 or the second PCB board 31. Specifically, the limiting rib 412 can abut against and limit the bottom end of the first PCB board 21 or the second PCB board 31, thereby further ensuring the stability of the position of the first antenna 2 and the second antenna 3.
[0040] In some embodiments, the base 4 is provided with through holes 413 corresponding to the first antenna 2 and the second antenna 3, respectively, and the through holes 413 are used to pass transmission wires. The transmission wires can connect the first antenna 2 and the second antenna 3 to the communication device, respectively, so that the communication device can transmit signals and power to the first antenna 2 and the second antenna 3, respectively, thereby realizing the transmission of wireless signals.
[0041] In some embodiments, the housing 1 and the base 4 are made of plastic or ceramic materials. The housing 1 and the base 4 are made of insulating materials such as plastic or ceramic, which can well ensure the electrical performance of the antenna, thereby ensuring the quality and stability of the antenna communication and preventing the antenna from being affected by other adverse factors during the communication process.
[0042] In summary, the embodiment of the utility model provides a composite rubber stick antenna, which realizes the integration of antennas of two working frequency bands by limiting and fixing two rigid PCB antennas in a shell 1. The isolation between the two antennas is ensured by arranging the two antennas in parallel and arranging the antenna parts at the two ends of the inner cavity 11 of the shell 1 respectively. While ensuring the wireless communication quality of the two antennas, the volume of the antenna on the wireless communication device is reduced, thereby reducing the design cost and production cost of the antenna components.
[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
