Description

Technical Field

[0001] This utility model relates to the field of mobile phone antenna technology, specifically a frame-type mobile phone antenna. Background Technology

[0002] Over the past three decades, mobile communications have developed rapidly, undergoing generation after generation of technological innovations. As the gateway to the internet, mobile phones have also undergone significant changes. From the first-generation "brick phones" of mobile communication, to the second-generation digital phones, to the third-generation multimedia phones, to the fourth-generation multi-functional smartphones, and finally to the future 5G high-speed multi-functional phones, mobile phone antennas have gradually evolved towards miniaturization, multi-frequency operation, and all-metal frames.

[0003] Currently, China has 2G, 3G, and LTE (4G) systems. The 2G system uses the 1710-1850MHz frequency band, the 3G system uses the 1880-2170MHz frequency band, and the LTE (4G) system uses the 2300-2690MHz frequency band. China's wireless communication system currently covers the 1710-2690MHz frequency band.

[0004] Meanwhile, on November 15, 2017, the Ministry of Industry and Information Technology issued a notice on matters related to the use of the 3300MHz-3600MHz and 4800MHz-5000MHz frequency bands for fifth-generation mobile communication systems, indicating that my country is about to enter the 5G era. As a representative of mobile communication, mobile phones will inevitably lead the trend of the 5G era.

[0005] Traditional mobile phone antennas are often separate from the phone frame. Therefore, when assembling a mobile phone, the antenna needs to be installed separately inside the phone frame, which increases the assembly process, increases assembly costs, and reduces the overall assembly speed. To address this, this utility model proposes a frame-type mobile phone antenna. Utility Model Content

The antenna body is integrally welded to the mobile phone frame through the first welding pieces, the second welding pieces and the third welding pieces to form a frame-type mobile phone antenna structure. The antenna body includes an antenna substrate, a high-frequency radiating arm is provided on one side of the antenna substrate, and a low-frequency radiating arm is provided on the other side of the antenna substrate.

During the production of the mobile phone frame, the compatible antenna body can be directly welded to the inside of the mobile phone frame, thereby forming an integrated frame and antenna structure. This structure can be used directly as a factory assembly structure. During the assembly of the mobile phone, the assembly process between the mobile phone antenna and the frame can be eliminated, achieving the practical effect of using the frame and antenna assembly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figure 1-3The present invention provides an embodiment of a frame-type mobile phone antenna, including a mobile phone frame 1, an antenna body 2 disposed at one corner of the mobile phone frame 1, a plurality of first welding pieces 3 fixedly installed on the front outer wall of the antenna body 2, a second welding piece 4 fixedly installed on the other outer wall of the antenna body 2, and a third welding piece 5 installed on the other outer wall of the front end of the antenna body 2. The antenna body 2 is integrally welded to the mobile phone frame 1 through the first welding pieces 3, the second welding pieces 4 and the third welding pieces 5 to form a frame-type mobile phone antenna structure.

[0024] In this structural design, the first welding piece 3, the second welding piece 4, and the third welding piece 5 are used in conjunction to weld the matching antenna body 2 directly into the inside of the phone frame 1 during the production of the phone frame. This forms an integrated frame and antenna structure for the phone, which can be used directly as a factory assembly structure. During the assembly of the phone, the assembly process between the phone antenna and the frame can be eliminated, and the phone has the practical effect of using the frame and antenna assembly. This reduces the overall assembly process of the phone, lowers the assembly cost, and increases the overall assembly speed of the phone.

[0025] Meanwhile, the antenna body 2 of this utility model has several welding point areas on its outer side, which has the practical effect of multi-point area welding, which can greatly improve the overall connection strength with the mobile phone frame, and has the effect of multi-point and multi-area reinforced connection assembly, making the structure more stable.

[0026] In this embodiment, the antenna body 2 includes an antenna substrate 201, a high-frequency radiating arm 202 is provided on one side of the antenna substrate 201, and a low-frequency radiating arm 203 is provided on the other side of the antenna substrate 201.

[0027] It should be further explained that the low-frequency radiating arm 203 includes a vertical short-circuit stub, which connects two first-level horizontal radiating arms to form an inverted "F" shaped structure design.

[0028] The high-frequency radiating arm 202 includes a vertical feed stub, and the tail end of the vertical feed stub is connected to a secondary horizontal radiating arm, forming an "L" shaped structure design.

[0029] This invention integrates a high-frequency radiating arm 202 and a low-frequency radiating arm 203 on a single antenna. The inverted F-shaped low-frequency radiating arm 203 and the L-shaped high-frequency radiating arm 202 work together to cover the Sub-6GHz frequency band and the millimeter-wave high-frequency band. Thus, the high-frequency radiating arm 202 and the low-frequency radiating arm 203 can meet the multi-band usage requirements of high and low frequencies.

[0030] In this embodiment, an isolation groove 6 is formed between the high-frequency radiating arm 202 and the low-frequency radiating arm 203 on the upper surface of the antenna substrate 201. The isolation groove 6 is coated with a carbon nanotube coating. The carbon nanotube coating has high conductivity, and through the coating characteristics, electromagnetic waves can be absorbed through eddy current loss, thereby further reducing the resonance interference between the high-frequency band and the low-frequency band, effectively improving the signal-to-noise ratio, avoiding mutual interference between high and low frequencies, and making it more practical.

[0031] In this embodiment, in order to ensure the normal feeding and grounding connection of the antenna, a number of feeding points 7 are provided on one side of the bottom end of the low-frequency radiating arm 203 and on the upper surface of the antenna substrate 201.

[0032] The lower surface of the high-frequency radiation arm 202 is provided with a first grounding layer 8, and the lower surface of the low-frequency radiation arm 203 is provided with a second grounding layer 9.

[0033] Working principle: This utility model uses the welding structure of the first welding piece 3, the second welding piece 4 and the third welding piece 5 in combination. When the mobile phone frame 1 is produced, the matching antenna body 2 can be directly welded to the inside of the mobile phone frame 1, thereby forming a frame-antenna assembly structure that can be directly used as a factory assembly structure. When the mobile phone is assembled, the assembly step of the mobile phone antenna can be eliminated, and it has the actual use effect of assembly. This can reduce the overall assembly process of the mobile phone, reduce the assembly cost, and improve the overall assembly speed of the mobile phone.

[0034] Meanwhile, the antenna body 2 of this utility model has several welding point areas on its outer side, which has the practical effect of multi-point area welding, which can greatly improve the overall connection strength with the mobile phone frame, and has the assembly effect of multi-point and multi-area reinforced connection, making the structure more stable in use.

[0035] Furthermore, this utility model integrates a high-frequency radiating arm 202 and a low-frequency radiating arm 203 on a single antenna. The inverted F-shaped low-frequency radiating arm 203 and the L-shaped high-frequency radiating arm 202 work together to cover the Sub-6GHz frequency band and the millimeter-wave high-frequency band. Thus, the high-frequency radiating arm 202 and the low-frequency radiating arm 203 can meet the multi-band usage requirements of high and low frequencies.

[0036] Meanwhile, the isolation groove 6 is coated with a carbon nanotube coating. The carbon nanotube coating has high conductivity, and through the coating characteristics, it can absorb electromagnetic waves through eddy current loss, thereby further reducing the resonance interference between high frequency and low frequency bands, effectively improving the signal-to-noise ratio, avoiding mutual interference between high and low frequencies, and making it more practical.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
