[0002] Security gateways typically integrate wireless circuitry, such as cellular communication modules, WiFi, Bluetooth, Z-wave, and low-frequency ISM bands for external sensors. These gateways usually include antennas to support wireless communication with external devices. However, integrating multiple antennas presents design challenges because many components emit electromagnetic interference (EMI). Close placement or direct contact between antennas makes isolating other integrated components significantly difficult, increasing the risk of mutual interference.

[0003] In the presence of numerous external devices, the proper functioning of a security gateway antenna can be challenging. Furthermore, the material composition of the building's walls can also affect antenna performance. For example, metal structures embedded in concrete or other materials can interfere with the normal operation of the device's antenna. Without careful consideration, the wireless performance of a security gateway can be significantly degraded due to wall interference or excessive external noise.

[0034] refer to Figures 1 to 2This application provides a 3D wireless multi-band antenna for a security gateway. The 3D wireless multi-band antenna includes an antenna carrier 1, a three-dimensional antenna 2, and an audio component body 3. There are multiple three-dimensional antennas 2, which are spaced apart on the antenna carrier 1. The audio component body 3 is connected to the antenna carrier 1, and the antenna carrier 1 and the audio component body 3 enclose a mounting hole 4 for installing the security gateway.

[0035] This application provides a 3D wireless multi-band antenna for a security gateway. By incorporating an antenna carrier 1, multiple three-dimensional antennas 2 are integrated onto the carrier 1, achieving space-saving design and a compact form factor. Furthermore, the multiple three-dimensional antennas 2 are positioned close to the antenna carrier 1, which itself can serve as an electromagnetic shielding material, reducing external electromagnetic interference. This 3D wireless multi-band antenna also allows for automated assembly, avoiding errors from manual assembly that could affect antenna performance. Additionally, by increasing the number of three-dimensional antennas 2, the application enhances penetration.

[0036] Specifically, the antenna carrier 1 is made of metal.

[0037] Specifically, the 3D wireless multi-band antenna of this application is suitable for a security gateway, with the antenna carrier 1 connected to the housing of the security gateway. The security gateway is also equipped with one or more processors and one or more memories for storing or temporarily storing data and instructions required by running programs or operating systems. The system supports receiving information and instructions from peripheral devices on different channels via the three-dimensional antenna 2 and executing corresponding programs accordingly.

[0038] The security gateway is equipped with an RF multi-band antenna. By adopting an antenna carrier design integrated with external structures (such as housing components), the antenna performance can be effectively improved, allowing the device to maintain high efficiency even when housed in a housing.

[0039] The three-dimensional antenna 2 consists of resonant elements on a flexible printed circuit board, which are mounted on the antenna carrier 1 and connected to the support structure via spring-type connectors.

[0040] refer to Figures 4-7 The three-dimensional antenna 2 includes a main body 21 and a fixing part 22 connected to each other. The main body 21 is connected to the antenna carrier 1. A first fixing point 5 is provided on the top of the antenna carrier 1. The fixing part 22 has a first fixing hole 23. The first fixing point 5 is configured to be located in the first fixing hole 23 to fix the three-dimensional antenna 2 and the antenna carrier.

[0041] Specifically, multiple three-dimensional antennas 2 are engraved on the antenna carrier 1, and can be installed in one go by fixing them at the first fixing point 5, saving installation time.

[0042] Since most existing security gateways adopt the FPC (Flexible Printed Circuit) design, the FPC needs to be attached to the non-metallic casing of the device, requiring a certain degree of flatness and cleanliness on the device surface. Any error in the FPC's attachment position or installation angle will affect the antenna's reception effect and performance. Furthermore, during the installation process of mounting the antenna onto the FPC, if the antenna is bent or squeezed, it may deform or be damaged, potentially affecting its electrical performance and mechanical strength. This application addresses this issue by employing an antenna carrier 1 design to connect the three-dimensional antenna 2 to the antenna carrier 1. This design boasts a compact size and enables automated assembly, avoiding the impact of errors during manual assembly on antenna performance.

[0043] refer to Figures 3 to 7 The fixing part 22 includes a first connecting part 24, a second connecting part 25 and a third connecting part 26 connected in sequence. The first connecting part 24 extends from one end of the main body 21 connected to the first connecting part 24 in a first direction and is connected to the second connecting part 25. The first connecting part 24 has a first fixing hole 23. The second connecting part 25 extends from one end of the first connecting part 24 in a second direction and is connected to one end of the third connecting part 26. The third connecting part extends from one end of the second connecting part 25 in a third direction. The first direction is opposite to the third direction, and the second direction is perpendicular to the first direction. The first connecting part 24, the second connecting part 25 and the third connecting part 26 enclose a limiting space to insert part of the antenna carrier 1 into the limiting space.

[0044] Specifically, the first direction is to the right along the length of the antenna carrier 1, the second direction is downward along the thickness of the antenna carrier 1, and the third direction is to the left along the length of the antenna carrier 1.

[0045] Specifically, the limiting space is a C-shaped structure. By inserting part of the side wall of the antenna carrier 1 into the limiting space, the C-shaped structure can effectively clamp part of the antenna carrier 1, further realizing the fixed stability between the three-dimensional antenna 2 and the antenna carrier 1.

[0046] refer to Figures 1-3 The top of the antenna carrier 1 is provided with a second fixing point 6, which is spaced apart from the first fixing point 5. The main body 21 is provided with a second fixing hole 27, and the second fixing point 6 is configured to be located in the second fixing hole 27, thereby further improving the fixing stability between the three-dimensional antenna 2 and the antenna carrier 1.

[0047] refer to Figure 1 and Figure 3The multiple three-dimensional antennas 2 include an LTE antenna, a WIFI antenna, a Z-Wave IoT antenna, and a Sub-GRF antenna. This application's multi-band antenna supports dual-band WiFi (2.4GHz and 5GHz), LTE, Bluetooth, Z-Wave, and Sub-G RF bands. The antenna structure can be designed to integrate radio frequency (RF) radiating elements within the mounting mechanism of an electronic device.

[0048] refer to Figure 1 and Figure 3 The antenna carrier 1 includes a first carrier 11, a second carrier 12 and a third carrier 13. The second carrier 12 is disposed between the first carrier 11 and the third carrier 13. The first carrier 11 and the third carrier 13 are vertically disposed at both ends of the second carrier 12. The second carrier 12 is horizontally disposed. Multiple three-dimensional antennas 2 are sequentially and spaced apart along the first carrier 11, the second carrier 12 and the third carrier 13.

[0049] In this embodiment, the LTE antenna is an LTE (4G / 5G) antenna, and there are two of them. One is set on the first carrier 11, and the other is set on the second carrier 12. The WIFI antenna is set on the second carrier 12, the ZWAVE IoT antenna is set on the second carrier 12, and the SubG RF is set on the third carrier 13. By setting three-dimensional antennas 2 at different angles, this application can receive and transmit signals from different spatial angles. This means that even if the signal of one antenna is attenuated due to obstacles (such as walls, buildings) or other factors, the other three-dimensional antennas 2 can receive stronger signals at different angles, avoiding the weak signal of a single signal source, helping to improve the signal reception quality, enhance anti-interference ability, and thus improve penetration.

[0050] refer to Figure 1 The antenna carrier 1 is provided with an antenna contact spring, and the bottom surface of the multiple three-dimensional antennas 2 is provided with an antenna feed point, which is connected to the antenna contact spring.

[0051] Specifically, the antenna feed point and the contact spring are connected by a contact, and the antenna feed point is not easy to loosen, which has the characteristic of stable connection.

The resonance box 32 is disposed on one side of the audio component body 3, the piezoelectric buzzer 33 is disposed on one side of the resonance box 32, and the speaker cover 34 is disposed between the piezoelectric buzzer 33 and the resonance box 32.
