[0037] The core of the present invention is to provide an antenna and electronic equipment. By mounting the entire antenna structure on different surfaces of a bracket, a three-dimensional folded structure antenna is formed. The antenna structure occupies a smaller area, which is conducive to the miniaturized design of the antenna and is conducive to practical application.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0039] Please refer to Figure 1 and Figure 2 , Figure 1 A schematic structural diagram of an antenna provided by the present invention is shown. Figure 2 This is a structural schematic diagram of another antenna provided by the present invention.

[0040] The antenna comprises:

[0041] The bracket 101 is provided on the electronic device board 100 and is a non-metallic polyhedron;

[0042] A first conductive portion 102 is provided on the first surface of the bracket 101. The first side of the first conductive portion 102 is used to connect to the radio frequency module on the electronic device board 100, the second side is grounded, and the third side extends to the first edge of the first surface;

[0043] The second conductive portion 103 and the first non-conductive portion 104 are both provided on the second surface of the bracket 101 , the second conductive portion 103 is connected to the first non-conductive portion 104 , and the second conductive portion 103 extends to the first edge to connect to the third side of the first conductive portion 102 , with the first surface adjacent to the second surface;

[0044] The RF module is used to provide a first feeding excitation so that the first conductive portion 102 , the second conductive portion 103 and the first non-conductive portion 104 work together to resonate under the first feeding excitation to generate an operating frequency band covering a first target bandwidth.

[0045] In this embodiment, considering that in the prior art, antennas designed for VR or AR devices typically employ a flat-lay structure, i.e., all antenna patterns are placed on the top surface of a support bracket. This results in the flat-lay structure occupying an excessively large size, and the correspondingly large volume of the entire support bracket, which is not conducive to the miniaturization of the antenna design. To address the above technical issues, the present application provides an antenna having a three-dimensional folded structure, which is more conducive to practical applications.

[0046] Specifically, the antenna can be applied to electronic devices, including but not limited to various VR devices or AR devices; the electronic device board 100 is mounted with multiple devices including a radio frequency module, and in essence, the electronic device board 100 can be understood as a metal circuit board; the bracket 101 is a non-metallic bracket, and its material is not limited to various non-conductive materials such as PVC plastic (Polyvinyl chloride, polyvinyl chloride), and the size of the bracket 101 includes but is not limited to a hollow polyhedron structure of 10mm*10mm*10mm and 1mm thick, and the polyhedron can be a cuboid or a cube (such as Figure 1 As shown, a left view of a cubic bracket 101 is shown, where the distance between the two squares of different sizes represents the thickness of the cube. Of course, the design can also be directly based on the above dimensions to achieve a standardized design of the antenna, which can be used in different types of electronic devices. The antenna structure in this application significantly reduces the space occupied by the supporting bracket and the overall structure of the flat antenna in the prior art, which can be reduced by 3 to 5 times, thereby reducing production costs. In addition, the fixing method between the bracket 101 and the electronic device board 100 includes but is not limited to relying on various processing techniques such as screws and riveting, which is determined according to actual needs and is not particularly limited here.

[0047] Preferably, the first surface may be any side surface of the bracket 101, and the second surface may be the top surface. Figure 2 , Figure 2 is a three-dimensional schematic diagram of the antenna, Figure 2 The cubic bracket 101 with a certain thickness is still used as an example for explanation, and the first surface can be specifically the right side surface. In addition, the antenna principle designed in this application can be understood as follows: the RF module is the feeding power source, providing a first feeding excitation, and the excitation current is transmitted to the second conductive part 103 via the first conductive part 102, and gathers at the connecting edge of the second conductive part 103 and the first non-conductive part 104, generating resonance and radiation, and finally generating an operating frequency band covering the first target bandwidth. In addition, the operating frequency band covering the first target bandwidth is specifically the UWB band. Of course, the wireless signal received by the antenna can also be fed to the RF module for signal processing.

[0048] In summary, the present application provides an antenna that utilizes the multi-faceted structural characteristics of the bracket 101 to mount the entire antenna structure on different surfaces of the bracket 101, forming an antenna with a three-dimensional folding structure. The antenna structure occupies a smaller area, which is conducive to the miniaturized design of the antenna and is conducive to practical applications.

[0049] Based on the above embodiment:

[0050] As a preferred embodiment, one end of the first conductive portion 102 has a strip-shaped non-conductive portion B and one side of the end is chamfered;

[0051] One side of the strip-shaped non-conductive portion B forms a conductive branch A, and the other side is a straight segment connected to the chamfer. There is a gap between the straight segment and the second edge of the first surface. The edge of the straight segment serves as the first side of the first conductive portion 102 and is connected to the RF module via the electrical connector 1010.

[0052] The end of the conductive branch A extends to the second edge of the first surface and serves as the second side of the first conductive portion 102 ; wherein the second edge is opposite to the first edge.

[0053] In this embodiment, the setting form of the first conductive part 102 on the first surface is given. First of all, it should be noted that the straight section is parallel to the second edge, and the width of the gap between the two is determined according to actual conditions, but it is necessary to ensure that the edge of the straight section is connected to the radio frequency module through the electrical connector 1010; the first conductive part 102 can essentially be an integrally formed structure, and the conductive branch A, also known as the grounding branch, is essentially a pattern feature on the integrally formed structure; the first conductive part 102 can specifically be implemented by relying on a conductive patch of a stamped sheet structure or an FPC (Flexible Printed Circuit) and the like to be set at the corresponding position of the bracket 101 body, and no special limitation is made here.

[0054] For details, please refer to Figure 3 , Figure 3 A schematic diagram of the structure of another antenna provided by the present invention, corresponding to Figure 2 , still taking the bracket 101 as a hollow cubic bracket 101 with a size of 10mm*10mm*10mm and a thickness of 1mm as an example, the actual pattern of the first conductive portion 102 on the first surface is given, combined with Figure 3 The area where the first conductive portion 102 is located is described below: Figure 3The area where the first conductive portion 102 is located is filled with dark gray. It can be seen that the edge of the first conductive portion 102 includes a first horizontal segment 1001, a first vertical segment 1002, a chamfered inclined segment 1003, a second horizontal segment 1004 (i.e., the straight segment described above), a second vertical segment 1005, a third horizontal segment 1006, a third vertical segment 1007, a fourth horizontal segment 1008 (i.e., the end of the conductive branch A described above) and a fourth vertical segment 1009, which are sequentially connected. It should be noted that the other end of the first conductive portion 102 extends to the first edge. Figure 3 In the embodiment, the first horizontal segment 1001 is the third side of the first conductive portion 102 extending to the first edge; the conductive branch A is located on the left side of the strip-shaped non-conductive portion B (for ease of explanation, Figure 3 The area where the electrical connector 1010 is located is indicated by a black filled cube, and the area where the strip non-conductive portion B is located is shown in FIG. Figure 3 The area excluding the area where the first conductive portion 102 is located, the area where the strip non-conductive portion B is located, and the area where the electrical connector 1010 is located is filled with light gray, and the strip non-conductive portion B can be specifically a first through hole hollowed out of the bracket 101 body at that location, as described below. Figure 3 The remaining area is also shown in light gray, and includes a rectangular structure plus a trapezoidal chamfered structure). It only needs to remain non-conductive. Since the bracket 101 itself is non-metallic, there is no need to add additional dielectrics. The original design of the remaining area of ​​the bracket 101 body can be directly maintained.

[0055] It should also be noted that in order to achieve a standardized design of the antenna, preferably, a method for designing the length of each edge of the first conductive portion 102 on the 10mm*10mm*10mm, 1mm thick hollow cube bracket 101 is given: the length of the second horizontal segment 1004 (that is, the straight segment described above) is set to 5mm, the distance between the second horizontal segment 1004 and the third edge of the first surface (that is, the edge where the first vertical segment 1002 is located) is the chamfered side length, which can be set to 3mm, the third horizontal segment 1006 is set to 1mm, the fourth horizontal segment 1008 is set to 1mm, the third vertical segment 1007 is set to 4mm, and the second vertical segment 1005 is set to 3mm. The above is only an example of a preferred setting, which can be adjusted according to actual needs.

[0056] In addition, the chamfer angle can be as follows Figure 3The 45 degrees shown can also be adjusted according to actual needs; the gradient structural design of the chamfered and straight sections (i.e. the above-mentioned chamfered inclined section 1003 and the second horizontal section 1004) improves the impedance characteristics of the UWB frequency band, i.e. the 6-9 GHz frequency band, and the antenna radiation effect is better.

[0057] As a preferred embodiment, the strip-shaped non-conductive portion B is a first through hole.

[0058] In this embodiment, the strip-shaped non-conductive portion B is provided as a first through hole, that is, a first through hole obtained by hollowing out the bracket 101 body at this position, and its preferred setting size can be that the third horizontal segment 1006 is set to 1mm, and the third vertical segment 1007 is set to 4mm, to form a 4mm*1mm gap, which cooperates with the conductive branch A to form a longer antenna ground loop; the setting size of the conductive branch A is 4mm*1mm, that is, the fourth horizontal segment 1008 is set to 1mm, combined with the third vertical segment 1007 to be set to 4mm, on the basis of taking into account the processing error, the above-mentioned antenna ground loop can reach about 8mm, as a balun structure, to achieve antenna impedance matching and bandwidth expansion in the UWB band.

[0059] As a preferred embodiment, the electrical connector 1010 is a conductive material piece integrated with the first conductive portion 102 .

[0060] In this embodiment, under the condition of high processing technology level, the electrical connector 1010 can be a conductive material piece integrally formed with the first conductive part 102, that is, Figure 3 The black area is the same as the dark grey area of ​​the first conductive portion 102 , being a branch formed integrally therewith and extending from the straight section. The conductive material of the first conductive portion 102 is the conductive material of the electrical connector 1010 .

[0061] As a preferred embodiment, a second through hole is provided in the gap, one end of the second through hole extends to the edge of the straight section, and the other end extends to the second edge;

[0062] The electrical connector 1010 is passed through the second through hole, with one end connected to the edge of the straight section and the other end connected to the RF module.

[0063] In this embodiment, when the processing technology level is limited, a second through hole can be provided at the gap. Then, the electrical connector 1010 can be various conductive structural parts, such as metal springs or ejector pins. The second through hole is opened as large as possible to ensure that it can accommodate electrical connectors 1010 of various sizes. Therefore, one end of the second through hole extends to the edge of the straight section, and the other end extends to the second edge. Specifically, Figure 3The black area in FIG is opened, and the electrical connector 1010 is passed through it to meet the input requirements of the feed excitation.

[0064] Please refer to Figure 4 , Figure 4 This is a structural schematic diagram of another antenna provided by the present invention.

[0065] As a preferred embodiment, the second surface is the top surface of the bracket 101;

[0066] The first non-conductive portion 104 extends to the first edge to connect to the third side of the first conductive portion 102 .

[0067] In this embodiment, the second surface is provided as the top surface of the bracket 101, and the second conductive portion 103 and the first non-conductive portion 104 are both provided on the top surface of the bracket 101, and preferably, the first non-conductive portion 104 can also extend to the first edge to connect with the third side of the first conductive portion 102. For details, please refer to Figure 4 , Figure 4 A schematic diagram of the arrangement of the first non-conductive part 104 and the second conductive part 103 is given in the figure, wherein the bracket 101 is a hollow cubic bracket 101 with a size of 10mm*10mm*10mm and a thickness of 1mm. The edge of the second conductive part 103 includes a fifth vertical segment 1031, a fifth horizontal segment 1032, a sixth vertical segment 1033, a sixth horizontal segment 1034, a seventh vertical segment 1035 and an eighth horizontal segment 1036 connected in sequence, wherein the eighth horizontal segment 1036 is connected to the first horizontal segment 1001 of the first conductive part 102; the ninth horizontal segment 1041 of the first non-conductive part 104 is also connected to the first horizontal segment 1001 of the first conductive part 102; the UWB frequency band RF current emitted by the RF module will be gathered and resonated at the conductive edge connecting the first conductive part 102 and the first non-conductive part 104 and the conductive edge connecting the second conductive part 103 and the first non-conductive part 104, thereby better achieving the radiation performance of the UWB frequency band.

[0068] Preferably, the shape of the first non-conductive part 104 can be rectangular, and its setting size can be 4mm*6mm. Since the sixth horizontal segment 1034 and the seventh vertical segment 1035 are the connecting edges of the first non-conductive part 104 and the second conductive part 103, the sixth horizontal segment 1034 can be set to 6mm and the seventh vertical segment 1035 can be set to 4mm.

[0069] As a preferred embodiment, the first non-conductive portion 104 is a third through hole.

[0070] In this embodiment, the first non-conductive portion 104 is provided as a third through hole in the form of a notch, that is, the third through hole is obtained by hollowing out the bracket 101 body at this position, thereby radiating the fed UWB RF current into the free space to realize the UWB frequency band working mode.

[0071] It should be noted that the specific shape of the third through hole can be as follows: Figure 4 The rectangle shown may also be a square, and there is no specific limitation on this, and it can be set according to actual needs.

[0072] As a preferred embodiment, the present invention further comprises:

[0073] The third conductive portion 105 and the second non-conductive portion 106 are both provided on the third surface of the bracket 101. The third conductive portion 105 is connected to the second non-conductive portion 106 and the second conductive portion 103 respectively. The third surface is adjacent to the second surface.

[0074] The RF module is further configured to provide a second feeding excitation so that the first conductive portion 102 , the second conductive portion 103 , the third conductive portion 105 and the second non-conductive portion 106 work together to resonate under the second feeding excitation to generate an operating frequency band covering a second target bandwidth.

[0075] In this embodiment, the antenna may further include a third conductive portion 105 and a second non-conductive portion 106 provided on the third surface of the bracket 101, thereby generating an operating frequency band covering the second target bandwidth, namely the 2.4 GHz band. It can be seen that through the antenna structure setting described in the above embodiment, a dual-line structure operating in the 2.4 GHz band and the UWB band can be comprehensively realized, which is beneficial to meeting the communication needs in different situations in actual production; in addition, the working principle of the antenna under the 2.4 GHz band is further explained as follows: the 2.4 GHz band RF current emitted by the RF module passes through the first conductive portion 102, the second conductive portion 103 and the third conductive portion 105, and then gathers at the conductive edge where the third conductive portion 105 and the second non-conductive portion 106 are connected, generating resonance, thereby realizing the 2.4 GHz band working mode; in addition, under the joint action of the conductive branch A and the strip-shaped non-conductive portion B, an antenna ground loop with a length of about 8 mm is formed, which also improves the circuit characteristics of the 2.4 GHz antenna band due to the low antenna height and the capacitive bias, thereby ensuring the antenna radiation effect in the 2.4 GHz band.

[0076] Please refer to Figure 5 , Figure 5 A schematic structural diagram of another antenna provided by the present invention, Figure 5Still taking the bracket 101 as a 10mm*10mm*10mm, 1mm thick hollow cube bracket 101 as an example for explanation, wherein the third conductive portion 105 can be specifically a rectangular conductive portion, and the edge of the third conductive portion 105 includes a tenth horizontal segment 1051, an eighth vertical segment 1052, an eleventh horizontal segment 1053 and a ninth vertical segment 1054 connected in sequence, wherein the eleventh horizontal segment 1053 is connected to the second non-conductive portion 106. Preferably, the setting size of the third conductive portion 105 can be as follows Figure 5 The 4mm*10mm shown, that is, the eighth vertical segment 1052 is 4mm, and the tenth horizontal segment 1051 is 10mm. When the side length of the cube bracket 101 is less than 10mm, the length of the eighth vertical segment 1052 can be increased to ensure the resonance effect of the antenna. The specific setting can be based on actual needs. Here is only a schematic diagram of the component size design of a standardized antenna.

[0077] It should also be noted that, preferably, the third surface is a side surface of the bracket 101, which can be specifically a side surface opposite to the first surface (see Figure 2 ,in Figure 2 Due to the limited display angle of the picture, only the exposed third conductive portion 105 and the second non-conductive portion 106 are framed with dotted lines, and the actual structure of the third conductive portion 105 and the second non-conductive portion 106 can be referred to. Figure 5 ), at this time, the tenth horizontal segment 1051 will be connected to the fifth horizontal segment 1032 of the second conductive part 103; the side surface can also be a side surface adjacent to both the first surface and the second surface, so that the tenth horizontal segment 1051 is connected to the sixth vertical segment 1033 of the second conductive part 103.

[0078] For an explanation of the actual working performance of the antenna proposed in the above embodiment, please refer to Figure 6 and Figure 7 , Figure 6 A schematic diagram showing the impedance distribution of an antenna provided by the present invention, showing the impedance distribution of an antenna according to Figure 2 The antenna structure shown is designed so that when the corresponding size setting is met, the impedance of the antenna can reach the preset target impedance, thereby achieving impedance matching; Figure 7 The schematic diagram of the bandwidth that can be covered by an antenna provided by the present invention shows the actual coverage effect of the antenna provided in this application. It can be seen that it does achieve coverage of the ultra-wideband UWB band and the 2.4GHz band on the basis of meeting the requirements of miniaturization and standardized design, has good working performance, and realizes a dual-line structure working in the 2.4GHz plus UWB band.
