DETAILED DESCRIPTION

[0045] In related technologies, with the continuous development of communication technology, the design of electronic products such as tablets and laptops has become increasingly thinner and lighter, and full-screen and all-metal shell designs are widely used in communication equipment such as laptops. The built-in antenna assembly is an important component of communication equipment, and communication equipment can receive and send signals through the antenna assembly. Conventional built-in antenna assemblies require a sufficiently large clearance space around the antenna, and the antenna radiation area must be clear and free of metal. The metal shell of a full-metal body product can easily shield the signal of the built-in antenna, resulting in poor performance of the antenna assembly, which is a major difficulty in antenna assembly design. Current communication equipment has less and less clearance area for antennas, which makes the layout space of the antenna assembly small, resulting in a decline in antenna performance, or squeezing out the space of other functional components, thereby affecting the functions of other functional components.

[0046] In view of this, the present application provides an antenna assembly and communication equipment, the antenna assembly including a conductive substrate and an antenna body, the conductive substrate including a first partition and a second partition arranged at intervals, the first partition and the second partition forming a sound outlet; the antenna body is arranged on the first partition, and the antenna body is at least used to form a signal together with the second partition. The present application uses the sound outlet on the conductive substrate to design the antenna assembly, and current is passed through the antenna body, so that a magnetic field is formed around the antenna body, and an induced current is formed on the adjacent second partition, and the induced current then forms an excitation magnetic field, thereby forming electromagnetic waves, that is, the antenna body and the second partition are coupled to form a radiated electromagnetic wave, and the sound outlet can avoid direct conduction between the antenna body and the second partition. Only a certain clearance area needs to be left near the sound outlet to achieve good antenna radiation performance. The requirement for the clearance area is very small, and it can be used in an environment with a very small clearance area. Space can be left for the design of other functional components, thereby reducing the mutual interference problem between other functional components and the antenna. It can not only meet the appearance requirements of the all-metal body, but also effectively improve the overall communication performance and enhance the user experience.

[0047] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0048] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0049] See also Figure 1-Figure 3 The present application provides an antenna assembly 1000, comprising a conductive substrate 100 and an antenna body 200. The conductive substrate 100 and the antenna body 200 are both metal parts.

[0050] See also Figure 1-Figure 2 In some embodiments of the present application, the conductive substrate 100 includes a first separator 110 and a second separator 120 spaced apart from each other. The first separator 110 and the second separator 120 are formed with sound outlet holes 300. The first separator 110 and the second separator 120 are both metal members. The first separator 110 can be a first metal strip, and the second separator 120 can be a second metal strip.

[0051] Specifically, one first partition 110 can be provided, and two second partitions 120 can be provided. The two second partitions 120 are located on both sides of the first partition 110, and a sound hole 300 is formed between the second partition 120 and the first partition 110, wherein the sound hole 300 passes through the conductive substrate 100 to facilitate sound to pass through the sound hole 300.

[0052] It should be noted that the conductive substrate 100 may further include a third separator and a fourth separator, etc., which are spaced apart. The third separator may be located on a side of the second separator 120 facing away from the first separator 110, with a sound outlet formed between the third separator and the second separator 120. The fourth separator may be located on a side of the third separator facing away from the second separator 120, with a sound outlet formed between the fourth separator and the third separator.

[0053] See also Figure 2 In some embodiments of the present application, the first separator 110 and the second separator 120 may be arranged in parallel. The lengths of the first separator 110 and the second separator 120 may be the same. The first separator 110 and the second separator 120 may extend in a direction parallel to the long side of the conductive substrate 100. Alternatively, the first separator 110 and the second separator 120 may extend in a direction parallel to the short side of the conductive substrate 100.

[0054] See also Figure 6 In some embodiments of the present application, the first separator 110 and the second separator 120 may be arranged in parallel. The extension direction of the first separator 110 and the second separator 120 may form an angle with the long side of the conductive substrate 100. The lengths of the first separator 110 and the second separator 120 may be the same or different.

[0055] In some embodiments of the present application, the antenna body 200 is disposed on the first separator 110. Specifically, the antenna body 200 and the first separator 110 can be fixed by welding, so that the antenna body 200 and the first separator 110 can be electrically connected and the connection stability between the antenna body 200 and the first separator 110 can be improved.

[0056] In some embodiments of the present application, the antenna body 200 is at least used to generate a signal together with the second separator 120. Specifically, the antenna body 200 and the second separator 120 can be coupled and excited to generate a radiated electromagnetic wave.

[0057] In some embodiments of the present application, a second separator 120 is provided on both sides of the first separator 110 , and the antenna body 200 is coupled with the second separators 120 on both sides to form a signal.

[0058] See also Figure 1In some embodiments of the present application, the antenna assembly further includes a circuit board 400. The circuit board 400 is disposed opposite the conductive substrate 100 and is electrically connected to the antenna body 200. It should be noted that the circuit board 400 may be the main control board of the antenna assembly 1000. The circuit board 400 is spaced apart from the conductive substrate 100, forming a receiving cavity therebetween.

[0059] In some embodiments of the present application, the circuit board 400 and the antenna body 200 are spaced apart from each other, so that a receiving gap is formed between the circuit board 400 and the antenna body 200 .

[0060] It should be noted that the antenna body 200 and the second partition 120 can be coupled and excited to form radiated electromagnetic waves. It is only necessary to leave a certain clearance area on the circuit board 400 in the projection area of ​​the sound outlet 300 and the matching circuit of the circuit board 400 to realize impedance matching adjustment, so as to achieve better antenna radiation performance, and thus the demand for clearance area is very small.

[0061] See also Figure 1 In some embodiments of the present application, the antenna body 200 is disposed on the surface of the first separator 110 facing the circuit board 400. That is, the antenna body 200 can be disposed opposite to the circuit board 400, facilitating electrical connection between the antenna body 200 and the circuit board 400.

[0062] Specifically, the antenna body 200 can be fixed to the surface of the first separator 110 facing the circuit board 400 by welding, so that the antenna body 200 and the first separator 110 can be electrically connected and the connection stability between the antenna body 200 and the first separator 110 can be improved.

[0063] See also Figure 2 and Figure 6 In some embodiments of the present application, the antenna body 200 has a signal feed point 140 and a ground feed point 150. The signal feed point 140 is the primary interface for the antenna assembly 1000 to receive or transmit signals. Through the signal feed point 140, signals are transmitted to the antenna assembly 1000 for radiation, or signals are received from the antenna assembly 1000. The ground feed point 150 is generally used to provide a reference ground or return path to help stabilize the performance of the antenna assembly 1000.

[0064] In some embodiments of the present application, the signal feeding point 140 and the ground feeding point 150 are both laser engraved, so that the signal feeding point 140 and the ground feeding point 150 are not easily corroded, which can reduce the failure rate of the antenna body 200 and increase the service life of the antenna body 200.

[0065] In some embodiments of the present application, the circuit board 400 is provided with a first connector 410 and a second connector 420 . The circuit board 400 is electrically connected to the signal feeding point 140 through the first connector 410 , and the circuit board 400 is electrically connected to the ground feeding point 150 through the second connector 420 .

[0066] Specifically, the first connector 410 can be an antenna feed spring, and the second connector 420 can be an antenna ground spring. The antenna body 200 is connected to the RF (radio frequency) signal source of the circuit board 400 through the antenna feed spring, and the antenna body 200 is grounded to the circuit board 400 through the antenna ground spring.

[0067] The antenna feed spring provides a signal path between the antenna body 200 and the circuit board 400, enabling efficient signal transmission and reception. The antenna ground spring provides an electrical connection between the antenna body 200 and the circuit board 400 ground, enabling the antenna body 200 to operate normally and transmit signals efficiently.

[0068] See also Figure 1 and Figure 3 In some embodiments of the present application, the antenna assembly further includes a sound output component 700. The sound output component 700 is disposed on the circuit board 400 and can output sound at least through the sound output hole 300. The sound output component 700 can be a speaker. The speaker is disposed on the circuit board 400, and the circuit board 400 can control the speaker's power and volume. The speaker can output sound at least through the sound output hole 300.

[0069] The sound outlet 300 can take into account both the speaker sound output function and the antenna radiation function, without the need for an additional antenna carrier, which can reduce the cost of antenna production.

[0070] The speaker's sound outlet area faces the sound outlet 300 formed by the first partition 110 and the second partition 120. The antenna body 200 and the second partition 120 are coupled and excited to form radiated electromagnetic waves. There is no need to open windows on other metal plate shells or sides of the communication equipment, maintaining a good appearance texture and high structural strength.

[0071] See also Figure 2 and Figure 6 In some embodiments of the present application, the first separator 110 can be reused to form the antenna body 200. That is, the antenna body 200 does not need to be provided separately, and the first separator 110 can be selected to serve as the antenna body 200. One end of the first separator 110 can be selected as the signal feed point 140, and the other end of the first separator 110 can be selected as the ground feed point 150. Adjusting the length and width of the first separator 110 can optimize the antenna radiation efficiency and improve the antenna signal quality.

[0072] See also Figure 2 and Figure 6In some embodiments of the present application, the conductive substrate 100 is provided with a clearance opening, which accommodates the first separator 110 and the second separator 120. The clearance opening can pass through the conductive substrate 100, and the first separator 110 and the second separator 120 are located within the clearance opening. The clearance opening can be rectangular or circular in shape, and is shown as a rectangle in the drawings.

[0073] See also Figure 2 and Figure 6 In some embodiments of the present application, the first end of the first partition 110 is connected to the first side wall of the clearance opening, and the second end of the first partition 110 is connected to the second side wall of the clearance opening.

[0074] It should be noted that the first partition 110 has a first end and a second end disposed opposite each other. The clearance opening has a first sidewall and a second sidewall disposed opposite each other. The first end of the first partition 110 can be welded to the first sidewall of the clearance opening, and the second end of the first partition 110 can be welded to the second sidewall of the clearance opening.

[0075] Alternatively, the first separator 110 is integrally formed on the conductive substrate 100 , which can eliminate the need for welding between the first separator 110 and the side wall of the clearance opening, making the first separator 110 more durable, greatly improving production efficiency, and reducing labor costs.

[0076] See also Figure 2 and Figure 6 In some embodiments of the present application, a first end of the first partition 110 is connected to a first side wall of the clearance opening, and a gap 130 is provided between a second end of the first partition 110 and a second side wall of the clearance opening.

[0077] It should be noted that the first end of the first separator 110 can be welded to the first sidewall of the clearance opening. Alternatively, the first separator 110 can be integrally formed with the conductive substrate 100, eliminating the need for welding between the first separator 110 and the sidewall of the clearance opening, thereby increasing the durability of the first separator 110. Plastic can be disposed between the second end of the first separator 110 and the second sidewall of the clearance opening to enhance the strength and stability of the first separator 110. Specifically, the plastic can be filled between the second end of the first separator 110 and the second sidewall of the clearance opening using computer numerical control (CNC) machining technology.

[0078] Adjusting the position of the ground feed point 150 can adjust the physical length of the antenna body 200 . Adjusting the physical length and width of the antenna body 200 can meet specific antenna frequency band requirements.

[0079] Depending on antenna debugging requirements, it can be selected whether the second end of the first partition 110 is connected to the second side wall of the clearance opening, or a gap 130 is provided between the second end of the first partition 110 and the second side wall of the clearance opening.

[0080] See also Figure 2 and Figure 6 In some embodiments of the present application, the width of the sound hole 300 is greater than or equal to 1.5 mm and less than or equal to 6.0 mm. For example, the width of the sound hole 300 can be 1.5 mm-2.0 mm, 2.0 mm-3.0 mm, 3.0 mm-4.0 mm, 4.0 mm-5.0 mm, or 5.0 mm-6.0 mm. For example, the width of the sound hole 300 can be 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, 3.5 mm, 4.0 mm, 4.5 mm, 5.0 mm, 5.5 mm, or 6.0 mm.

[0081] It should be noted that when the width of the sound hole 300 is less than 1.5 mm, the antenna radiation efficiency is low, affecting the antenna signal quality; when the width of the sound hole 300 is greater than 6.0 mm, it is not easy to couple to form radiated electromagnetic waves; adjusting the width of the sound hole 300 can optimize the antenna radiation efficiency and improve the antenna signal quality.

[0082] See also Figure 1-Figure 3 and Figure 6 In some embodiments of the present application, the antenna assembly further includes a dust screen 500, which covers the opening and at least a portion of the first partition 110 and the second partition 120. The dust screen 500 effectively blocks dust and particulate matter in the air from passing through the conductive substrate 100, protecting components such as the circuit board 400 and the sound output element 700, thereby reducing the frequency and cost of cleaning and maintenance of the antenna assembly 1000.

[0083] See also Figure 7 In some embodiments of the present application, the circuit board 400 is provided with a matching device, and the matching device is electrically connected to the signal feeding point 140 through the first connector 410. The matching device can form a matching circuit. A π-type circuit (or a double L-type circuit) is added to the feeding position of the RF (Radio Frequency) main circuit 460 of the matching circuit to perform antenna matching debugging. The RF main circuit 460 includes a first matching device 430, a second matching device 440 and a third matching device 450. Among them, the first matching device 430, the second matching device 440 and the third matching device 450 can be inductors or capacitors. For example, the first matching device 430 is an inductor, the second matching device 440 is an inductor, and the third matching device 450 is a capacitor. The unit of inductance is nH (nanohenry), and the inductance value can be 1.0nH~33nH. The unit of capacitance is pF (picofarad), and the capacitance value can be 0.25pF~33pF.

[0084] See also Figure 7In some embodiments of the present application, the circuit board 400 is provided with a switch tuning device 470 , and the switch tuning device 470 is connected to the ground feeding point through the second connecting member 420 .

[0085] The switch tuning device 470 can be an SPST (Single Pole Single Throw), SP2T (Single Pole Double Throw), SP4T (Single Pole Four Throw), etc. The switch can control the values ​​of the inductor and capacitor to change the current return path, thereby changing the antenna excitation mode, so that the antenna body 200 produces the desired multiple resonances.

[0086] Impedance matching can be adjusted by debugging the matching circuit on circuit board 400, allowing the antenna assembly to simultaneously support the reception and transmission of electromagnetic wave signals in at least the first frequency band, as well as the reception and transmission of electromagnetic wave signals in the higher-frequency second frequency band. By adjusting the impedance matching, the impedance matching can simultaneously meet the impedance matching requirements of the first and second frequency bands, thereby ensuring that the antenna radiation efficiency in both the first and second frequency bands meets the requirements, effectively widening the bandwidth and covering the needs of dual-band antennas.

[0087] The following description uses a WiFi antenna as an example. The first frequency band and the second frequency band can be the 2.4G_WiFi and 5G_WiFi frequency bands of the WiFi antenna, respectively.

[0088] See also Figure 8 , Figure 8 Figure 2 shows the return loss of the antenna assembly. Through simulation and debugging, the return loss for the first frequency band (2.4 GHz) is approximately -11.388 dB, and the return loss for the second frequency band (5 GHz to 6 GHz) is -6.3 to -11.93 dB. This indicates that the return loss of antenna assembly 1000 is low, indicating good performance.

[0089] See also Figure 9 , Figure 9 Figures 2 and 3 show the Wi-Fi antenna's radiation efficiency curve, S_Tot, and the system's total efficiency curve, S_Rad. The first frequency band, 2.4G_WiFi, has a radiation efficiency of approximately -3.5dB at 2.4-2.5GHz, achieving good antenna radiation efficiency. The second frequency band, 5G_WiFi, has a radiation efficiency of -4.1-5.4dB at 5.1-6.5GHz. This demonstrates the excellent performance of antenna assembly 1000.

[0090] It should be noted that the antenna assembly 1000 can also be applied to two frequency bands in the medium and high frequencies, or two frequency bands in the low frequencies, etc. in a cellular communication network.

[0091] When a gap 130 is provided between the second end of the first partition 110 (i.e., the antenna body) and the second sidewall of the clearance opening, the antenna grounding spring is not grounded, and the antenna assembly 1000 is in the form of a primitive monopole antenna, forming a 1 / 4 wavelength antenna. The primitive monopole antenna can be applied to a single resonant antenna with a narrow bandwidth. It can be the GPS L5 band (resonant frequency of 1176 MHz), the GPS L1 band (resonant frequency of 1575 MHz), the BDS B2 band (resonant frequency of 1207 MHz), the BDS B1 band (resonant frequency of 1561 MHz), the GAL E5b band (resonant frequency of 1207 MHz), a BT antenna, and so on.

[0092] See also Figure 4 The present application provides a communication device, including a conductive housing and the aforementioned antenna assembly 1000, wherein the antenna assembly 1000 is disposed in the conductive housing. The communication device may be a laptop computer, a tablet computer, or the like.

[0093] See also Figure 4-Figure 5 In some embodiments of the present application, the conductive housing includes a first shell and a second shell connected to each other, the first shell and the second shell being disposed opposite each other. The first shell and the second shell are both metal parts. One of the first shell and the second shell forms a conductive substrate 100.

[0094] For example, taking the communication device as a laptop computer for illustration, the first housing may be a metal surface where the keyboard is located, and the second housing may be a metal surface opposite to the metal surface where the keyboard is located.

[0095] See also Figures 1-4 The conductive substrate 100 may be a first housing, and the second housing may be a metal housing 600 .

[0096] See also Figure 5-Figure 6 The conductive substrate 100 may be a second housing. The first housing may be a metal housing 600. The metal housing 600 is provided with heat dissipation holes 610 to facilitate heat dissipation of the laptop computer.

[0097] It should be noted that most existing antenna assemblies require at least two upper and lower metal shells to have clearance gaps, or side windows, which have relatively high requirements for the clearance environment. This application only requires one side of the metal shell to have an opening gap, which can not only meet the appearance requirements of the all-metal body, but also effectively improve the overall communication performance and enhance the user experience.
