[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] like Figures 1-7 As shown, this embodiment provides a communication device, including a housing 1, a circuit board 2, and a first antenna device 4 and a second antenna device 5 with different antenna types;

[0043] The housing 1 has a first surface (not shown) that is covered by the user's palm when the user holds it and a second surface 13 that exposes the user's palm. An inner cavity is formed between the first surface and the second surface 13. The circuit board 2 is located in the inner cavity. The circuit board has a first plate surface 21 adjacent to the second surface 13. A first antenna region 211 and a second antenna region 713 are formed between the first plate surface 21 and the second surface 13. A first antenna device 4 is arranged in the first antenna region 211 and a second antenna device 5 is arranged in the second antenna region 713. The first antenna region 211 and the second antenna region 713 are arranged sequentially along the length direction of the communication device.

[0044] This embodiment arranges an antenna area on the first plate surface 21 adjacent to the second surface 13, and utilizes the positional characteristics of the second surface 13 exposing the user's palm to avoid the user's palm directly blocking the antenna, thereby reducing the absorption and reflection of electromagnetic waves by the human body, reducing signal attenuation, and significantly enhancing the signal transmission and reception performance of the communication device.

[0045] Furthermore, the first antenna device 4 and the second antenna device 5 have different antenna types. For example, the first antenna device 4 includes a satellite antenna, while the second antenna device 5 includes a main communication antenna (such as UHF / VHF band) or an auxiliary antenna (such as Bluetooth / Wi-Fi). This helps to achieve spatial isolation of multi-band signals, reduce inter-band interference, and optimize the overall communication quality.

[0046] Specifically, the communication device in this embodiment also includes a battery 3, which is located in the inner cavity and is electrically connected to the circuit board 2 to provide power support to the circuit board 2.

[0047] Specifically, the communication device in this embodiment is a walkie-talkie.

[0048] like Figure 3As shown, in one embodiment, the length L5 of the communication device is between 70mm and 110mm. Preferably, the length L5 of the communication device is between 75mm and 95mm, but is not limited thereto.

[0049] like Figure 3 As shown, in one embodiment, the width L6 of the communication device is between 35mm and 70mm. Specifically, the width L6 of the communication device is between 40mm and 60mm, but is not limited to this.

[0050] like Figure 3 As shown, in one embodiment, the thickness L7 of the communication device is between 8mm and 25mm. Specifically, the thickness L7 of the communication device is between 10mm and 20mm, but is not limited to this.

[0051] This embodiment makes the communication device of moderate size, ensuring comfortable grip, and has a compact structure that requires little storage space, allowing it to be easily put into a pocket or backpack, helping to free up hands and improve freedom of movement.

[0052] like Figures 1 to 7 As shown, in one embodiment, the first antenna device 4 includes a satellite antenna. The second antenna device includes one or more combinations of a UHF antenna, a VHF antenna, a Bluetooth antenna, a Wi-Fi antenna, and a cellular network antenna.

[0053] The communication device in this embodiment has a satellite antenna and other types of antennas, which expands the communication coverage and enables seamless coverage worldwide.

[0054] like Figure 5 and Figure 7 As shown, in one embodiment, the first antenna device 4 includes a first sub-antenna 41 and a second sub-antenna 42, and the first sub-antenna 41 and the second sub-antenna 42 have the same antenna type.

[0055] The second antenna device 5 includes sub-secondary antenna 1 51, sub-secondary antenna 2 52 and sub-secondary antenna 3 53, and the antenna types of sub-secondary antenna 1 51, sub-secondary antenna 2 52 and sub-secondary antenna 3 53 are all different.

[0056] This embodiment allows for the selection of different antennas for communication based on varying application scenarios and requirements. For example, Bluetooth or Wi-Fi antennas can be used for data transmission between devices over short distances; while satellite antennas or cellular network antennas can be used for long distances or in remote areas. This embodiment increases the communication flexibility and adaptability of the communication device.

[0057] The second antenna device 5 in this embodiment includes three different types of antennas. Since different antennas support different communication methods and technical standards, this embodiment enables the communication device to have multiple communication methods. When one communication method fails due to fault, interference or network congestion, it can be quickly switched to other available communication methods, thereby improving the overall reliability and stability of the system.

[0058] like Figure 1 As shown, in one embodiment, the distance between the midpoint of the first antenna region 211 and the top of the second surface 13 is less than the distance between the midpoint of the first antenna region 211 and the bottom of the second surface 13.

[0059] The distance between the midpoint of the second antenna region 713 and the top of the second surface 13 is greater than the distance between the midpoint of the second antenna region 713 and the bottom of the second surface 13.

[0060] In this embodiment, the length of the first antenna region 211 is relatively small, and the length of the second antenna region 713 is relatively long, thereby making the area of ​​the second antenna region 713 larger, so as to increase the deployment area of ​​the second antenna device 5, and at the same time, it is beneficial to deploy multiple sub-second antennas of different antenna types in the second antenna device 5.

[0061] like Figure 2 As shown, in one embodiment, in the length direction of the first plate surface 21, the length L1 of the first antenna region 211 is between 12-40mm, and the length L2 of the second antenna region 713 is between 30-70mm; in the width direction of the first plate surface 21, the width L3 of the first antenna region 211 is between 40-70mm, and the width L4 of the second antenna region 713 is between 40-70mm.

[0062] This embodiment makes the length of the first antenna region 211 smaller and the length of the second antenna region 713 longer, so that antennas of different frequencies can be deployed based on the lengths of the first antenna region 211 and the second antenna region 713, thereby improving frequency band adaptability.

[0063] For example, the first antenna region 211 is used to deploy satellite antennas (such as L / S / Ku bands). Due to its high operating frequency (1-18GHz), the shorter length of the first antenna region 211 can optimize the impedance matching of high-frequency signals and reduce signal reflection loss.

[0064] For example, the second antenna region 713 is used to deploy other antennas (such as UHF / VHF bands). The longer length of the second antenna region 713 can adapt to the long wavelength characteristics of low-frequency signals and enhance signal acquisition capability.

[0065] like Figures 4 to 6As shown, in one embodiment, the communication device further includes an inner frame 7, which is located in the inner cavity; and the inner frame 7 is located between the first plate surface 21 and the second surface 13; a first antenna region 211 is formed on the first plate surface 21, and a second antenna region 713 is formed on the inner frame 7.

[0066] This embodiment further increases the distance between the first antenna device 4 and the second antenna device 5 by distributing the first antenna region 211 and the second antenna region 713 on the first plate 21 and the inner frame 7 respectively, thereby enhancing the spatial isolation of multi-band signals, reducing inter-band interference, and optimizing the overall communication quality.

[0067] like Figures 4 to 7 As shown, in one embodiment, the inner frame 7 has a first frame surface close to the first plate surface 21 and a second frame surface 712 away from the first plate surface 21, on which a second antenna region 713 is formed.

[0068] In this embodiment, the second antenna device 5 is positioned on the second frame surface 712, which is far away from the first plate surface 21, so that the second antenna device 5 is further away from the first antenna device 4, further reducing inter-band interference and optimizing the overall communication quality.

[0069] like Figures 5 to 7 As shown, in one embodiment, the inner frame 7 has a bottom wall 71 and side walls 72 extending outward from both sides of the bottom wall 71. A receiving cavity 73 is formed between the bottom wall 71 and the two side walls 72, and each of the two side walls 72 is provided with a claw 721 for confining the circuit board 2 within the receiving cavity 73. The surface of the bottom wall 71 near the receiving cavity 73 forms a first frame surface, and the surface of the bottom wall 71 away from the receiving cavity 73 forms a second frame surface 712.

[0070] In this embodiment, the circuit board 2 is confined within the receiving cavity 73 by the claw 721, preventing the circuit board 2 from detaching from the receiving cavity 73 and improving the stability of the communication device. Furthermore, during the assembly process of the communication device, the circuit board 2 can be pre-installed on the inner frame 7, eliminating the need for subsequent alignment and assembly of the circuit board 2, thus simplifying the assembly process.

[0071] like Figure 4 As shown, in one embodiment, the housing 1 includes a first housing 141 and a second housing 151, which are interlocked in the longitudinal direction of the communication device to confine the inner frame 7 within the inner cavity.

[0072] In this embodiment, by setting an inner frame 7, the circuit board 2 and the speaker 4 can be pre-installed on the inner frame 7 during the assembly process, which simplifies the assembly process and improves assembly efficiency.
