Description

Technical Field

[0001] This invention relates to the field of antenna technology, and more particularly to an antenna and a wearable device. Background Technology

[0002] With societal development and the continuous advancement of electronic technology, people have increasingly higher demands for the transmission rate, channel capacity, and communication quality of communication systems. Traditional single-antenna systems can no longer meet current needs, thus leading to the emergence of Multiple-Input Multiple-Output (MIMO) technology, which utilizes multiple antenna elements working together. MIMO systems provide multiple paths for data transmission by placing multiple antennas at the input and output ends, enabling parallel communication. However, currently, it is impossible to ensure that the feeding results of each port in the antenna are consistent during parallel communication, resulting in unstable signal transmission.

[0003] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0004] The main objective of this invention is to provide an antenna and a wearable device that solves the technical problem that the prior art cannot ensure consistent power supply results at each port of the antenna during parallel operation, leading to unstable signal transmission.

[0005] To achieve the above objectives, the present invention provides an antenna, the antenna comprising:

[0006] A dielectric substrate, wherein a power supply port is provided on each of the four sides of the dielectric substrate;

[0007] Multiple sub-antennas are respectively disposed on the front side of the dielectric substrate, and each sub-antenna is disposed at the position of a feed port.

[0008] Each of the sub-antennas, under the action of feeding, excites a corresponding feeding port.

[0009] Optionally, the sub-antenna includes:

[0010] Radiation patches;

[0011] A feeder cable, one end of which is connected to the feeder port, and the other end of which is connected to the radiating patch;

[0012] Grounding pads are provided on both sides of the feeder wire;

[0013] The radiating patch is used, in conjunction with the grounding patch, to excite each feed port of the dielectric substrate when fed by the feed line.

[0014] Optionally, a preset gap is provided between the grounding patch and the feeder wire and the radiating patch.

[0015] Optionally, the grounding patch includes: a first grounding patch and a second grounding patch;

[0016] The first grounding patch is disposed on one side of the feeder wire, and the second grounding patch is disposed on the other side of the feeder wire.

[0017] Optionally, the preset gap includes: a first gap and a second gap;

[0018] A first gap is provided between the first grounding patch and the feeder wire, and a second gap is provided between the second grounding patch and the feeder wire.

[0019] Optionally, the radiating patch includes a first radiating patch and a second radiating patch;

[0020] The first radiating patch is a rectangular radiating patch, and the second radiating patch is an arc-shaped radiating patch. One end of the first radiating patch is connected to the feeder wire, and the other end is connected to the second radiating patch.

[0021] Optionally, multiple sub-antennas are arranged around the center of the dielectric substrate to form a centrally symmetrical ring array.

[0022] Optionally, the dielectric substrate is a flexible dielectric substrate.

[0023] In addition, to achieve the above objectives, the present invention also proposes a wearable device, which includes the antenna described above.

[0024] Optionally, the wearable device includes: a smartwatch or VR glasses.

[0025] This invention provides an antenna and a wearable device, comprising: a dielectric substrate and a plurality of sub-antennas. A feed port is disposed on each of the four sides of the dielectric substrate. The plurality of sub-antennas are respectively disposed on the front side of the dielectric substrate, each sub-antenna corresponding to a feed port. Under feeding, each sub-antenna excites a corresponding feed port. Because this application provides a sub-antenna at each feed port position around the dielectric substrate, it effectively improves the data transmission rate while achieving parallel communication. Since the plurality of sub-antennas on the four sides of the dielectric substrate form an array antenna structure, the feeding results of each feed port on the dielectric substrate are consistent.

[0033] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0034] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0035] The core of this application is to provide an antenna and a wearable device that aims to solve the problem that the existing technology cannot ensure that the power supply results of each port in the antenna are consistent during parallel operation, resulting in unstable signal transmission.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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 some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] Please refer to Figure 1 , Figure 1 This application provides a schematic diagram of the structure of an antenna, which includes:

[0038] A dielectric substrate 1, wherein a power supply port 2 is provided on each of the four sides of the dielectric substrate 1;

[0039] Multiple sub-antennas 3 are respectively disposed on the front side of the dielectric substrate 1, and each sub-antenna 3 is disposed at the position of a feed port 2.

[0040] Each of the sub-antennas 3 is excited by a corresponding feed port 2 under the action of the feed.

[0041] It should be noted that the antenna in this embodiment adopts a double-layer structure. One layer of the antenna is a dielectric substrate 1, and the other layer is a plurality of sub-antenna 3 structures laid on the front side of the dielectric substrate 1. The sub-antenna 3 structures may include radiating patches 31, feed lines 32, and grounding patches 33, etc.

[0042] It should be understood that, since a feed port 2 is provided on each of the four sides of the dielectric substrate 1 in this embodiment, and a sub-antenna 3 structure for feeding and excitation is provided at the position of each feed port 2, the feeding result of each feed port 2 of the antenna is the same under the feeding action of the sub-antenna 3, which effectively improves the stability of the antenna signal transmission. Furthermore, since multiple feed ports 2 are provided on the dielectric substrate 1 in this embodiment, each feed port 2 can realize parallel communication of the antenna under the action of the corresponding sub-antenna 3, which improves the reliability and stability of the signal, and achieves efficient signal transmission without expanding the signal bandwidth.

[0043] Furthermore, multiple sub-antennas 3 are arranged around the center of the dielectric substrate 1 to form a centrally symmetrical ring array.

[0044] It should be noted that in this embodiment, the antenna uses Rogers 5880 (εr = 2.2, tanδ = 0.0009) as a substrate, and the single antennas are combined to form a centrally symmetrical array antenna structure. Therefore, the antenna has four feed ports 2 that can be fed. Since each sub-antenna 3 is centrally symmetrical based on the center position of the dielectric substrate 1, the feeding results of the four feed ports of the antenna are the same, thereby improving the reliability and stability of the signal.

[0045] Furthermore, referring to Figure 2 , Figure 2 The above is a schematic diagram of the structure of the sub-antenna 3, which includes:

[0046] Radiation patch 31;

[0047] Feeder cable 32, one end of which is connected to the feeder port 2, and the other end of which is connected to the radiating patch 31;

[0048] Grounding patch 33, the grounding patch 33 is respectively provided on both sides of the feed line 32, wherein a preset gap is provided between the grounding patch 33 and the feed line 32 and the radiating patch 31;

[0049] The radiating patch 31 is used, under the power supply of the feed line 32, to work together with the grounding patch 33 to excite each feed port 2 of the dielectric substrate 1.

[0050] It should be noted that the aforementioned radiating patch 31, feed line 32 and grounding patch 33 are all laid on the front side of the aforementioned dielectric substrate 1. The aforementioned radiating patch 31, feed line 32 and grounding patch 33 can be metal materials with good conductivity and low cost, such as copper, that is, the aforementioned radiating patch 31, feed line 32 and grounding patch 33 can be metal patches.

[0051] It should be understood that each power supply port 2 on the dielectric substrate 1 is connected to a power supply line 32, and the power supply line 32 is connected to a radiating patch 31. Grounding patches 33 are also provided on both sides of the power supply line 32. The grounding patches 33 are grounded (GND). Furthermore, there is a certain preset gap between the grounding patches 33 and the power supply line 32, thereby ensuring that there is no overlapping structure between the grounding patches 33 and the power supply line 32. There is also a certain preset gap between the grounding patches 33 and the radiating patches 31, thereby ensuring that there is no overlapping structure between the grounding patches 33 and the radiating patches 31.

[0052] In the specific implementation, since each feed port 2 on the dielectric substrate 1 is connected to a feed wire 32, and the feed wire 32 is connected to a radiating patch 31, and grounding patches 33 are also provided on both sides of the feed wire 32, the radiating patch 31, under the feeding action of the feed wire 32, works together with the grounding patch 33 to excite each feed port 2 of the dielectric substrate 1, thereby achieving the same feeding result for each feed port 2 of the antenna, effectively improving the stability of the antenna signal transmission.

[0053] It should be understood that the antenna in this embodiment can be used to cover the surface of the communication device. If the communication device is a transmitting device, the communication device can transmit radio frequency energy to the radiating patch 31 through the feed line 32 and the radiating patch 31 will emit it. If the communication device is a receiving device, the communication device can receive radio frequency energy transmitted from the outside through the radiating patch 31 and transmit it to the device for processing through the feed line 32.

[0054] Furthermore, referring to Figure 3 , Figure 3 This is a schematic diagram of the antenna planar structure in this embodiment. The grounding patch 33 includes: a first grounding patch 331 and a second grounding patch 332.

[0055] The first grounding patch 331 is disposed on one side of the feed line 32, and the second grounding patch 332 is disposed on the other side of the feed line 32; thereby effectively widening the bandwidth of the antenna.

[0056] The preset gap includes: a first gap and a second gap;

[0057] A first gap is provided between the first grounding patch 331 and the feeder wire 32, and a second gap is provided between the second grounding patch 332 and the feeder wire 32;

[0058] The radiation patch 31 includes a first radiation patch 311 and a second radiation patch 312;

[0059] The first radiating patch 311 is a rectangular radiating patch 31, and the second radiating patch 312 is an arc-shaped radiating patch 31. One end of the first radiating patch 311 is connected to the feeder wire 32, and the other end is connected to the second radiating patch 312.

[0060] It should be noted that the first grounding patch 331 and the second grounding patch 332 are both rectangular grounding patches 33. The first grounding patch 331 and the second grounding patch 332 are respectively disposed on both sides of the feeder line 32. The first grounding patch 331 and the second grounding patch 332 are respectively grounded. The first grounding patch 331 and the second grounding patch 332 are both made of metal. A first gap is provided between the first grounding patch 331 and the feeder line 32 to ensure that there is no overlapping structure between the first grounding patch 331 and the feeder line 32. A second gap is provided between the second grounding patch 332 and the feeder line 32 to ensure that there is no overlapping structure between the second grounding patch 332 and the feeder line 32.

[0061] It should be understood that, with reference Figure 2 and Figure 3 In this embodiment, Figure 2 and Figure 3 The dimensional parameters of each part of the antenna structure are shown in Table 1. Table 1 is a schematic table of antenna parameters provided in this embodiment.

[0062]

[0063] Table 1 Antenna Size Parameters

[0064] Where Wsub is the width of dielectric substrate 1;

[0065] Lsub is the length of dielectric substrate 1;

[0066] Hsub is the thickness of dielectric substrate 1;

[0067] Wpatch is the width of the first radiating patch 311;

[0068] R is the radius length of the second radiating patch 312;

[0073] Lgnd2 is the length of the second grounding patch 332;

[0074] Wgnd2 is the width of the second grounding patch 332.

[0075] It should be noted that the radiating patch 31 in the sub-antenna 3 may include a first radiating patch 311 and a second radiating patch 312. The first radiating patch 311 may be a rectangular radiating patch 31, for example, a square radiating patch 31, etc. In this embodiment, the side length of the first radiating patch 311 may be the size of Wpatch in Table 1 above. The second radiating patch 312 may be an arc-shaped radiating patch 31, for example, a semi-circular radiating patch 31, and in this embodiment, the radius of the second radiating patch 312 may be the size R in Table 1 above.

[0076] It should be understood that, since the radiating patches 31 in the prior art are all single-structure designs, the current path of the radiating patch 31 is not large enough, resulting in low signal transmission efficiency. Therefore, in this embodiment, the radiating patch 31 includes a first radiating patch 311 and a second radiating patch 312. Compared with the single-structure radiating patch 31, the overall radiating patch 31 structure composed of the first radiating patch 311 and the second radiating patch has a larger transmission path, which is beneficial to reducing the antenna resonant frequency, increasing the transmission bandwidth, and thus improving the signal transmission efficiency.

[0077] Furthermore, the dielectric substrate 1 is a flexible dielectric substrate 1.

[0078] It should be noted that, in this embodiment, the antenna specifically uses polyimide flexible material as the dielectric substrate 1. The dielectric constant εr of the dielectric substrate 1 is 3.5, and the loss tangent tanδ of the dielectric substrate 1 is 0.002. (This is in conjunction with Table 1 above.) Figure 2 The antenna size parameters shown are used to analyze the antenna reflection coefficient and antenna efficiency at each feed port 2 of the antenna array structure. The analysis results are referenced. Figure 4 , Figure 4 This is a schematic diagram of the parameters for each feed port 2, where S11, S21, S31, and S41 are the parameter curves for each feed port, with the horizontal axis representing bandwidth and the vertical axis representing gain. Figure 4 When the antenna is at -10dB, the bandwidth range is 22.28GHz to 51.96GHz, thus ensuring that the performance of the four feed ports is the same and realizing an antenna bandwidth of over 29GHz. According to Shannon's theorem, the data transmission rate is relatively fast and it can be applied to high-frequency multi-port devices.

[0079] This embodiment provides an antenna, including: a dielectric substrate 1 and a plurality of sub-antennas 3. A feed port 2 is respectively disposed around the perimeter of the dielectric substrate 1. The plurality of sub-antennas 3 are respectively disposed on the front side of the dielectric substrate 1. Each sub-antenna 3 is disposed at the position of a feed port 2. Under the feeding action, each sub-antenna 3 excites a corresponding feed port 2. Since this application provides a sub-antenna 3 at the feed port positions around the perimeter of the dielectric substrate 1, the data transmission rate is effectively improved on the basis of realizing parallel communication. Since the plurality of sub-antennas 3 on the perimeter of the dielectric substrate 1 form an array antenna structure, the feeding results of each feed port 2 on the dielectric substrate 1 are consistent.

[0080] To address the aforementioned technical problems, this application also provides a wearable device, which includes the aforementioned antenna.

[0081] In one preferred embodiment, the wearable device includes a smartwatch or VR glasses.

[0082] Of course, other electronic devices may also be used, but this application does not limit them here.

[0083] This embodiment provides a wearable device, which includes the aforementioned antenna. The antenna includes a dielectric substrate 1 and multiple sub-antennas 3. A feed port 2 is respectively disposed around the perimeter of the dielectric substrate 1. The multiple sub-antennas 3 are respectively disposed on the front side of the dielectric substrate 1. Each sub-antenna 3 is disposed at the position of a feed port 2. Under the feeding action, each sub-antenna 3 excites a corresponding feed port 2. Since this application provides a sub-antenna 3 at the feed port positions around the perimeter of the dielectric substrate 1, the data transmission rate is effectively improved on the basis of parallel communication. Since the multiple sub-antennas 3 on the perimeter of the dielectric substrate 1 form an array antenna structure, the feeding results of each feed port 2 on the dielectric substrate 1 are consistent.

[0084] It should be noted that the antenna in this embodiment adopts a double-layer structure. One layer of the antenna is a dielectric substrate 1, and the other layer is a plurality of sub-antenna 3 structures laid on the front side of the dielectric substrate 1. The sub-antenna 3 structures may include radiating patches 31, feed lines 32, and grounding patches 33, etc.

[0085] It should be understood that, since a feed port 2 is provided on each of the four sides of the dielectric substrate 1 in this embodiment, and a sub-antenna 3 structure for feeding and excitation is provided at the position of each feed port 2, the feeding result of each feed port 2 of the antenna is the same under the feeding action of the sub-antenna 3, which effectively improves the stability of the antenna signal transmission. Furthermore, since multiple feed ports 2 are provided on the dielectric substrate 1 in this embodiment, each feed port 2 can realize parallel communication of the antenna under the action of the corresponding sub-antenna 3, which improves the reliability and stability of the signal, and achieves efficient signal transmission without expanding the signal bandwidth.

[0086] It should be noted that multiple sub-antennas 3 are arranged around the center position of the dielectric substrate 1 to form a centrally symmetrical ring array. In this embodiment, the antenna uses Rogers 5880 (εr=2.2,tanδ=0.0009) as the substrate. The single antennas are combined to form a centrally symmetrical array antenna structure. Therefore, the antenna has four feed ports 2 that can be fed. Since each sub-antenna 3 is centrally symmetrical based on the center position of the dielectric substrate 1, the feeding results of the four feed ports of the antenna are the same, thereby improving the reliability and stability of the signal.

[0087] It should be noted that the aforementioned radiating patch 31, feed line 32 and grounding patch 33 are all laid on the front side of the aforementioned dielectric substrate 1. The aforementioned radiating patch 31, feed line 32 and grounding patch 33 can be metal materials with good conductivity and low cost, such as copper, that is, the aforementioned radiating patch 31, feed line 32 and grounding patch 33 can be metal patches.

[0088] It should be understood that each power supply port 2 on the dielectric substrate 1 is connected to a power supply line 32, and the power supply line 32 is connected to a radiating patch 31. Grounding patches 33 are also provided on both sides of the power supply line 32. The grounding patches 33 are grounded (GND). Furthermore, there is a certain preset gap between the grounding patches 33 and the power supply line 32, thereby ensuring that there is no overlapping structure between the grounding patches 33 and the power supply line 32. There is also a certain preset gap between the grounding patches 33 and the radiating patches 31, thereby ensuring that there is no overlapping structure between the grounding patches 33 and the radiating patches 31.

[0089] In the specific implementation, since each feed port 2 on the dielectric substrate 1 is connected to a feed wire 32, and the feed wire 32 is connected to a radiating patch 31, and grounding patches 33 are also provided on both sides of the feed wire 32, the radiating patch 31, under the feeding action of the feed wire 32, works together with the grounding patch 33 to excite each feed port 2 of the dielectric substrate 1, thereby achieving the same feeding result for each feed port 2 of the antenna, effectively improving the stability of the antenna signal transmission.

[0090] It should be understood that the antenna in this embodiment can be used to cover the surface of the communication device. If the communication device is a transmitting device, the communication device can transmit radio frequency energy to the radiating patch 31 through the feed line 32 and the radiating patch 31 will emit it. If the communication device is a receiving device, the communication device can receive radio frequency energy transmitted from the outside through the radiating patch 31 and transmit it to the device for processing through the feed line 32.

[0091] It should be noted that the first grounding patch 331 and the second grounding patch 332 are both rectangular grounding patches 33. The first grounding patch 331 and the second grounding patch 332 are respectively disposed on both sides of the feeder line 32. The first grounding patch 331 and the second grounding patch 332 are respectively grounded. The first grounding patch 331 and the second grounding patch 332 are both made of metal. A first gap is provided between the first grounding patch 331 and the feeder line 32 to ensure that there is no overlapping structure between the first grounding patch 331 and the feeder line 32. A second gap is provided between the second grounding patch 332 and the feeder line 32 to ensure that there is no overlapping structure between the second grounding patch 332 and the feeder line 32.

[0092] It should be noted that the radiating patch 31 in the sub-antenna 3 may include a first radiating patch 311 and a second radiating patch 312. The first radiating patch 311 may be a rectangular radiating patch 31, for example, a square radiating patch 31, etc. In this embodiment, the side length of the first radiating patch 311 may be the size of Wpatch in Table 1 above. The second radiating patch 312 may be an arc-shaped radiating patch 31, for example, a semi-circular radiating patch 31, and in this embodiment, the radius of the second radiating patch 312 may be the size R in Table 1 above.

[0093] It should be understood that, since the radiating patches 31 in the prior art are all single-structure designs, the current path of the radiating patch 31 is not large enough, resulting in low signal transmission efficiency. Therefore, in this embodiment, the radiating patch 31 includes a first radiating patch 311 and a second radiating patch 312. Compared with the single-structure radiating patch 31, the overall radiating patch 31 structure composed of the first radiating patch 311 and the second radiating patch has a larger transmission path, which is beneficial to reducing the antenna resonant frequency, increasing the transmission bandwidth, and thus improving the signal transmission efficiency.

[0094] It should be noted that, in this embodiment, the antenna specifically uses polyimide flexible material as the dielectric substrate 1. The dielectric constant εr of the dielectric substrate 1 is 3.5, and the loss tangent tanδ of the dielectric substrate 1 is 0.002. (This is in conjunction with Table 1 above.) Figure 2 The antenna size parameters shown are used to analyze the antenna reflection coefficient and antenna efficiency at each feed port 2 of the antenna array structure. The analysis results are referenced. Figure 4 , Figure 4 This is a schematic diagram of the parameters for each feed port 2, where S11, S21, S31, and S41 are the parameter curves for each feed port, with the horizontal axis representing bandwidth and the vertical axis representing gain. Figure 4 When the antenna is at -10dB, the bandwidth range is 22.28GHz to 51.96GHz, thus ensuring that the performance of the four feed ports is the same and realizing an antenna bandwidth of over 29GHz. According to Shannon's theorem, the data transmission rate is relatively fast and it can be applied to high-frequency multi-port devices.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
