[0038] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0039] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0040] Figure 1 This is a schematic diagram of the structure of a high-gain antenna device provided in an embodiment of this utility model. Figure 2 This is a schematic diagram of another high-gain antenna device provided in this embodiment of the present invention. Figure 3 This is a schematic diagram of an antenna gain circuit provided in an embodiment of the present invention, for reference. Figures 1 to 3 The high-gain antenna device includes: an antenna gain circuit 10, a metal protective shell 20, and multiple antennas 30; the antenna gain circuit 10 includes an RF signal relay terminal 11, a signal amplification module 12, and multiple antenna terminals 13; the first RF signal terminal of the signal amplification module 12 is electrically connected to each antenna terminal 13; the second RF signal terminal of the signal amplification module 12 is electrically connected to the RF signal relay terminal 11; the metal protective shell 20 includes an upper shell 21 and a lower shell 22; the upper shell 21 and the lower shell 22 are detachably connected and form a circuit housing space; the antenna gain circuit 10 is located within the circuit housing space; the upper shell 21 is provided with multiple through holes 211 corresponding to each antenna terminal 13; each antenna 30 is detachably connected to each antenna terminal 13 through each through hole 211.

[0041] The antenna gain circuit 10 includes a radio frequency (RF) signal relay 11, a signal amplification module 12, and multiple antenna terminals 13. Each antenna terminal 13 transmits the RF signal received by each antenna 30 to the signal amplification module 12, which amplifies the RF signal to increase its strength. The amplified RF signal is then relayed through the RF signal relay 11, allowing external wireless transceivers, such as routers and gateways, to receive the amplified signal. The RF signal relay 11 can replace the original wireless transceiver of a router or gateway through interface adaptation, thereby enhancing the signal received by the router or gateway.

[0042] The metal protective shell 20 includes a circuit housing space formed by an upper shell 21 and a lower shell 22. The antenna gain circuit 10 is located within this circuit housing space. The metal protective shell 20 protects the internal antenna gain circuit 10. The metal material effectively resists external environmental stress, ensuring the stability of the high-gain antenna device. Simultaneously, the excellent thermal conductivity of the metal material allows for good heat dissipation of the antenna gain circuit 10, improving the operating efficiency of the high-gain antenna device. Furthermore, the metal protective shell 20 effectively shields external signals, reducing electromagnetic radiation interference from surrounding electronic devices and preventing external signals from interfering with the signals in the antenna gain circuit 10. This ensures stable operation of the antenna gain circuit 10 and improves the accuracy of the signals processed by it. The upper shell 21 and lower shell 22 of the metal protective shell 20 are detachably connected. The connection method between the upper shell 21 and lower shell 22 can be a snap-fit ​​connection, a fastener connection, or an adhesive connection, facilitating the maintenance and repair of the internal antenna gain circuit 10.

[0043] Multiple antennas 30 can receive radio frequency signals separately. The multiple antennas 30 are connected to each antenna terminal 13 respectively, so that the signals received by the multiple antennas 30 can be combined at the first radio frequency signal terminal of the signal amplification module 12, thereby keeping the noise power unchanged and obtaining array gain. After the signal amplification module 12 amplifies the signal, the radio frequency signal forwarding terminal 11 forwards the amplified radio frequency signal to the external wireless transceiver, effectively improving the signal power.

[0044] In addition, the upper shell 21 of the metal protective shell 20 is provided with a plurality of through holes 211. The number and position of the through holes 211 correspond one-to-one with the antenna terminals 13. That is, the number of through holes 211 can be the same as the number of antenna terminals 13. Each antenna 30 can pass through the upper shell 21 through each through hole 211 and be detachably connected to each antenna terminal 13. This allows the number of connected antennas to be adjusted according to actual needs, and facilitates the adjustment of the installation position of the antenna 30. The connection method between the antenna 30 and the antenna terminal 13 can be magnetic connection, threaded connection, adhesive connection, snap-fit ​​connection, plug-in connection, etc. This utility model embodiment does not limit this.

[0045] This embodiment connects multiple antennas to an antenna gain circuit, allowing the signals received by these antennas to be amplified by the antenna gain circuit, thereby improving the strength of the wireless signal received by the wireless transceiver system. Simultaneously, by placing the antenna gain circuit within a metal protective housing, external interference signals are effectively shielded, and rapid heat dissipation is achieved. Furthermore, the detachable connection between the antenna terminals and the antenna gain circuit allows for adjustment of the number of connected antennas as needed, enhancing the installation flexibility of the high-gain antenna device and making it suitable for various application scenarios.

[0046] Optional, continue to refer to Figure 1 The antenna 30 includes an antenna body 31 and a signal adapter cable 32; one end of the signal adapter cable 32 is electrically connected to the antenna body 31, and the other end of the signal adapter cable 32 is detachably connected to the antenna terminal 13.

[0047] The antenna 30 includes an antenna body 31 and a signal adapter cable 32. The antenna body 31 receives radio frequency (RF) signals, which can be WiFi signals. One end of the signal adapter cable 32 is electrically connected to the antenna body 31, and the other end is detachably connected to the antenna terminal 13. This allows the antenna body 31 to transmit the RF signals received by the antenna body 31 to the antenna terminal 13. The detachable connection between the signal adapter cable 32 and the antenna terminal 13 allows the user to control the connection status between the antenna 30 and the antenna terminal 13, improving the installation flexibility of the high-gain antenna device. The signal adapter cable 32 can be greater than or equal to 1 meter in length. A sufficiently long signal adapter cable 32 allows the antenna body 31 to be flexibly placed in various locations or corners, effectively receiving signals from different locations without moving the metal protective shell 20.

[0048] Optional, continue to refer to Figure 1 The high-gain antenna device also includes: a plurality of antenna connection lines 40 corresponding one-to-one with each antenna 30; the antenna connection lines 40 are connected between the antenna 30 and the antenna terminal 13.

[0049] In this design, by providing an antenna connection line 40 between each antenna 30 and the antenna terminal 13, the antenna connection line 40 can serve as a connecting component between the antenna 30 and the antenna terminal 13, which helps to improve the convenience of connection between the antenna 30 and the antenna terminal 13.

[0050] Optional, continue to refer to Figure 1 The antenna connection line 40 includes a board connector 41, an antenna connector 42, and a flexible connection line 43 that is connected to the board connector 41 and the antenna connector 42 respectively; the board connector 41 is detachably connected to the antenna terminal 13; the antenna connector 42 extends out of the upper housing 21 through the through hole 211; the antenna 30 is detachably connected to the antenna connector 42 that extends out of the upper housing 21.

[0051] By making the board connector 41 detachably connected to the antenna terminal 13, and the antenna 30 detachably connected to the antenna connector 42 extending from the upper housing 21, when it is necessary to reduce or replace the antenna 30, only the antenna 30 and the antenna connector 42 need to be removed, without separating the upper housing 21 and the lower housing 22 of the metal protective housing 20. This reduces the user's maintenance and installation costs and improves operating efficiency. At the same time, the flexible connecting line 43 is connected to the board connector 41 and the antenna connector 42 respectively. The flexible connecting line 43 can be bent and arranged inside the metal protective housing 20 without damaging the antenna gain circuit 10.

[0052] Optional, continue to refer to Figure 1 and Figure 2 The high-gain antenna device also includes: an RF connector 50 and an RF adapter cable 60; one end of the RF connector 50 is connected to the RF signal relay terminal 11, and the other end of the RF connector 50 is connected to the RF adapter cable 60; the RF adapter cable 60 is used to connect to an external wireless transceiver device; the lower housing 22 includes a base plate 221 and a side plate 222 surrounding the base plate 221 and perpendicularly connected to the base plate 221; the side plate 222 is provided with a connector opening 2221; some of the RF connectors 50 extend out of the lower housing 22 through the connector opening 2221 and connect to the RF adapter cable 60.

[0053] The RF connector 50 extends out of the metal housing through the connector opening 2221, so that the RF connector 50 can be connected to the RF adapter cable 60. The amplified RF signal is transmitted from the RF signal relay end 11 to the RF adapter cable 60 through the RF connector 50. The RF signal is then transmitted from the RF adapter cable 60 to the external wireless transceiver, thereby improving the stability of signal transmission.

[0054] Optional, Figure 4 This is a schematic diagram of another antenna gain circuit provided in an embodiment of this utility model, for reference. Figure 4The antenna gain circuit 10 also includes a power supply module 14; the power supply module 14 is electrically connected to the power signal terminal of the signal amplification module 12.

[0055] The power supply module 14 is used to provide power to the antenna gain circuit 10 so that the signal amplification module 12 can amplify the signal normally.

[0056] Optional, continue to refer to Figures 1 to 4 The high-gain antenna device also includes: a power adapter 70; a power module 14 including a charging interface 141 and a power supply unit 142; the power signal input terminal of the power supply unit 142 is connected to the charging interface 141, and the power signal output terminal of the power supply unit 142 is electrically connected to the power signal terminal of the signal amplification module 12; a power opening 23 is also provided on the metal protective shell 20, which covers the charging interface 141; the power adapter 70 is pluggable to the charging interface 141.

[0057] The metal protective shell 20 has a power opening 23 that covers the charging interface 141, allowing the power adapter 70 to be inserted into the charging interface 141 through the power opening 23 without removing the metal protective shell 20, thus providing power to the antenna gain circuit 10. The power supply unit 142 processes the power signal to ensure that the processed power signal meets the power supply requirements of the signal amplification module 12, enabling the processed power signal to be transmitted to the power signal terminal of the signal amplification module 12, ensuring that the signal amplification module 12 receives a continuous and stable operating voltage.

[0059] The first capacitor C1, the second capacitor C2, the third capacitor C3, and the first inductor L1 together form an LC oscillation circuit. The DC power supply signal is converted into a stable AC signal through the LC oscillation circuit, and the AC signal is transmitted to the signal amplification module 12 through the power signal output terminal to ensure that the signal amplification module 12 can accurately amplify the radio frequency signal.

[0061] The fourth capacitor C4 is electrically connected to the first RF signal terminal of the RF amplifier U1. The fourth capacitor C4 is used to block the DC signal transmitted from the antenna terminal 13 to the first RF signal terminal, and only allows the RF AC signal to be transmitted to the RF amplifier U1, so as to avoid the DC signal causing the RF amplifier U1 to malfunction. The fifth capacitor C5 is electrically connected to the second RF signal terminal of the RF amplifier U1. The fifth capacitor C5 is used to block the DC signal at the second RF signal terminal of the RF amplifier U1 and transmit the amplified RF AC signal to the RF signal relay terminal 11, so as to ensure the overall compatibility and stability of the circuit and improve the signal enhancement effect.

[0062] For example, the plurality of antenna terminals 13 may include a first antenna terminal U2, a second antenna terminal U3, a third antenna terminal U4, and a fourth antenna terminal U5, which are arranged alternately.
