Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This application claims priority based on a Chinese patent application bearing patent application number 202210581634.5, filing date May 26, 2022, and title of "Antenna-integrated vehicle glass, manufacturing method and vehicle."

[0002] The present invention relates to the technical field of vehicle glass, and in particular to an antenna-integrated vehicle glass, a manufacturing method thereof, and a vehicle. [Background technology]

[0003] GNSS antennas are an essential part of satellite positioning systems. Existing GNSS antennas are generally made of high dielectric constant ceramics or PCB materials as their base material, and are stacked in multiple layers to achieve multi-band operation. Each band is excited by its own separate power supply method, and ultimately an antenna with a certain thickness is designed.

[0004] With the development of V2X technology, the requirements for location accuracy such as vehicle navigation, monitoring, warning, and scheduling collection based on location information are getting higher and higher; with the boom of Internet cars, new applications such as car calls, information announcements, electronic bulletin boards, and vehicle logistics are also emerging. Meanwhile, the design of new cars requires aesthetics, and after the application of multi-communication and positioning systems, there is almost no position and space for installing an antenna outside the car, so all new cars move the antenna inside the car, which not only completely deteriorates the performance of the antenna, but also has different antenna installation positions depending on the car model, which has completely different effects on the antenna; this type of antenna must meet specific performance requirements, and a separate protective cover is provided to protect the entire main body material, so it is large in size and heavy, and the layout of the position inside the car is limited; and it is generally attached to the glass by adhesion on the outside, so when there is a certain acceleration or when it is subjected to gravity for a long time and is in an accelerated state, it exerts a large stress on the glass, which causes damage due to the stress concentration on the glass. Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention aims to provide an antenna-integrated vehicle glass and a manufacturing method thereof in order to solve the technical problems that the installation position of an antenna on a vehicle is limited and the glass is damaged because the antenna is fixed to the glass by adhesive from the outside. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention provides a manufacturing method for an antenna-integrated vehicle glass, the method including the steps of: preparing a first glass plate; laying a metal layer on a first surface of the first glass plate and cutting at least one annular groove in the metal layer to form an antenna radiation layer; and laying at least one feeding microstrip line on a second surface of the first glass plate to form a feeding network layer, the feeding network layer being configured to couple to the antenna radiation layer and feed power to excite a radio frequency electromagnetic field between the first glass plate and the antenna radiation layer.

[0007] The present invention further provides an antenna-integrated vehicle glass comprising: a first glass plate having a first surface and a second surface; an antenna radiating layer laid on the first surface of the first glass plate, the antenna radiating layer including a metal layer having at least one annular groove cut therein; and a feeding network layer laid on the second surface of the first glass plate, the feeding network layer including at least one feeding microstrip line, the feeding network layer being coupled to and feeding the antenna radiating layer to excite a radio frequency electromagnetic field between the first glass plate and the antenna radiating layer.

[0008] The present invention further provides a vehicle including a vehicle glass having the above-mentioned antenna integrated therein. Effect of the Invention

[0009] The vehicle glass with integrated antenna and its manufacturing method of the present invention comprises forming an antenna radiating layer on a first surface of a first glass sheet, forming a power supply network layer on a second surface of the first glass sheet, and further coupling and supplying power to the antenna radiating layer through the power supply network layer to excite a radio frequency electromagnetic field between the first glass sheet and the antenna radiating layer, thereby providing the vehicle glass with antenna performance. This solves the problem that stress is concentrated locally on the vehicle glass due to the antenna structure when the vehicle is running by mounting the antenna structure on the vehicle glass, which makes the vehicle glass prone to damage, and solves the problem that after the antenna is mounted on the vehicle, the antenna's inherent performance is deteriorated due to being blocked by glass or other materials, making it unable to operate normally, or the mounting space on the vehicle is limited, making the performance unstable. Furthermore, the structure of the first glass sheet is not destroyed, so the strength of the structure of the first glass sheet is not affected. Meanwhile, the performance of the antenna of the vehicle glass of the present invention is designed based on the structure of the first glass sheet itself, so that it can be applied to various models of vehicles.

[0012] The following provides a clear and complete description of the technical solutions according to the embodiments of the present invention with reference to the drawings of the embodiments of the present invention, but of course these embodiments are only some of the embodiments of the present invention and do not mean all the embodiments. Based on the embodiments of the present invention, all other embodiments that can be obtained by those skilled in the art without any inventive ideas should be understood to fall within the scope of protection of the present invention.

[0013] (Embodiment 1) As shown in FIGS. 1, 2, 3 and 4, the present invention provides a manufacturing method for an antenna-integrated vehicle glass, the manufacturing method including the steps of: preparing a first glass plate 1; laying a metal layer 21 on a first surface 11 of the first glass plate 1, and cutting at least one annular groove 22 in the metal layer 21 to form an antenna radiating layer 2; and laying at least one feeding microstrip line 31 on a second surface 12 of the first glass plate 1 to form a feeding network layer 3, in which the feeding network layer 3 is configured to couple to and feed power to the antenna radiating layer 2, and excite a radio frequency electromagnetic field between the first glass plate 1 and the antenna radiating layer 2.

[0014] The manufacturing method of the vehicle glass integrated with an antenna according to the present invention comprises forming an antenna radiation layer 2 on a first surface 11 of a first glass plate 1, forming a power supply network layer 3 on a second surface 12 of the first glass plate 1, and coupling and supplying power to the antenna radiation layer 2 through the power supply network layer 3 to excite a radio frequency electromagnetic field between the first glass plate 1 and the antenna radiation layer 2, thereby making the vehicle glass have antenna performance. By mounting an antenna structure on the vehicle glass, the problem of stress concentration on a local part of the vehicle glass due to the antenna structure while the vehicle is running, which makes the vehicle glass easily damaged, is solved, and the problem of the antenna structure having a limited mounting space on the vehicle and therefore unstable performance is solved. Furthermore, the structure of the first glass plate is not destroyed, so that the strength of the structure of the first glass plate is not affected. Meanwhile, the performance of the antenna of the vehicle glass of the present invention is designed based on the structure of the first glass plate itself, so that it can be applied to various models of vehicles.

[0015] Specifically, the -10 dB impedance bandwidth of the antenna radiating layer 2 on the vehicle glass of the present invention can cover 1.164 GHz to 1.589 GHz, so that the antenna performance of the vehicle glass of the present invention can be used to receive signals in the frequency range of 1140 MHz to 1320 MHz and the frequency range of 1540 MHz to 1620 MHz covered by the satellite positioning system. Preferably, the operating bandwidth of the antenna radiating layer can be adjusted to be applicable to other wireless communication systems.

[0016] As shown in FIG. 3, in an embodiment of the present invention, the antenna radiation layer 2 is formed by integrally combining the forming process of the vehicle glass, and includes the steps of printing and forming a metal layer 21 on the first surface 11 of the first glass plate 1, and cutting an inner annular groove 221 for exciting high frequency waves and an outer annular groove 222 for exciting low frequency waves, which are arranged concentrically from the inside to the outside, into the metal layer 21 by etching. In this embodiment, the metal layer 21 is directly printed on the first surface 11 of the first glass plate 1, so that the metal layer 21 and the first glass plate 1 are directly and stably coupled to ensure the stability of the antenna performance. By feeding power to the antenna radiation layer 2 through the power feeding network layer 3, the energy is coupled to the outer annular groove 222 to form a low frequency resonance point, so that the low band signal can be received, and the energy is coupled to the inner annular groove 221 to form a high frequency resonance point, so that the high band signal can be received. Therefore, the vehicle glass integrated with the antenna of the present invention has the performance of a dual frequency antenna, and the high frequency resonance frequency and the low frequency resonance frequency, and the separation between the high frequency and the low frequency can be controlled by controlling the size of the inner annular groove 221 and the size of the outer annular groove 222. Meanwhile, the inner annular groove 221 and the outer annular groove 222 are cut into the metal layer 21 by etching, so as to prevent the first glass sheet 1 from being destroyed during the slotting process. Specifically, the metal layer 21 is formed by printing silver paste on the first surface 11 of the first glass sheet 1. Preferably, the metal layer is adhered to the thin metal sheet on the first surface of the first glass sheet. Preferably, the metal layer is made of copper, aluminum or gold. Preferably, the metal layer is formed on the first surface of the first glass sheet by plating. Preferably, the inner annular groove and the outer annular groove are cut into the metal layer by cutting.

[0017] 3, in an embodiment of the present invention, the dielectric constant of the first glass sheet 1 is determined according to the thickness of the first glass sheet 1, the medium wavelength when the electromagnetic wave propagates through the first glass sheet 1 is determined according to the dielectric constant of the first glass sheet 1 and the frequency range to be covered by the antenna radiating layer 2, and the inner and outer diameters of the inner annular groove 221 and the outer annular groove 222 are determined according to the medium wavelength. The sizes of the inner annular groove 221 and the outer annular groove 222 are designed based on the thickness and dielectric constant of the first glass sheet 1 itself, and the frequency range covered by the antenna radiating layer meets the requirements, so that the vehicle glass of each vehicle type or each part can be manufactured into the vehicle glass integrated with the antenna according to the present invention.

[0018] Specifically, the medium wavelength is expressed by the formula TIFF2025511629000002.tif1253 where c is the speed at which the electromagnetic wave propagates in free space, c is the frequency of the electromagnetic wave, λ is the wavelength at which the electromagnetic wave propagates in free space, λr is the medium wavelength, and ε r is the dielectric constant of the first glass plate 1 (related to the thickness of the first glass plate 1). In this embodiment, the thickness of the first glass plate 1 is 2.1 mm. The dielectric constant of the first glass plate 1 is 6.7. The impedance bandwidth that the antenna radiating layer 2 must cover is 1.164 GHz to 1.589 GHz, and the frequency range that the antenna radiating layer 2 must cover is 1165 MHz to 1300 MHz for low frequencies, 1520 MHz to 1660 MHz for high frequencies, and 1.375 GHz for intermediate frequencies. The medium wavelength when the electromagnetic wave propagates through the first glass plate 1 is 84.3 mm.

[0019] When the medium wavelength is λr, the outer diameter of the inner annular groove 221 is 0.17λr to 0.19λr, the inner diameter of the inner annular groove 221 is 0.15λr to 0.17λr, the outer diameter of the outer annular groove 222 is 0.21λr to 0.23λr, and the inner diameter of the outer annular groove 222 is 0.19λr to 0.21λr. The outer diameter of the inner annular groove 221 is preferably 14.78 mm. The inner diameter of the inner annular groove 221 is 12.7 mm. The outer diameter of the outer annular groove 222 is 20.33 mm. The inner diameter of the outer annular groove 222 is 16.99 mm. On the other hand, the influence of the length and width of the metal layer 21 on the antenna performance is small, and it is sufficient to select an appropriate length and width based on the size of the first glass plate 1. In this embodiment, the length and width of the metal layer 21 are both 96 mm.

[0020] 4, in the embodiment of the present invention, four power feeding microstrip lines 31 are uniformly formed on the second surface 12 of the first glass plate 1 along the circumferential direction of the inner annular groove 221 and the outer annular groove 222, and the power feeding microstrip lines 31 are provided along the radial direction of the inner annular groove 221 and the outer annular groove 222, and power is coupled to the antenna radiating layer 2 through the four power feeding microstrip lines 31. The phase difference between the power feeding portions of the four power feeding microstrip lines 31 is 90 degrees, thereby realizing right-rotating circular polarization, with high phase accuracy and good stability.

[0021] Specifically, the feeding microstrip line uses a stub transmission run with a characteristic impedance of 50 Ω. Preferably, the feeding network layer is coupled and fed by two feeding microstrip lines arranged opposite to each other. Preferably, the feeding network layer is coupled and fed by only one feeding microstrip line.

[0022] The length of the feeding microstrip line 31 is 0.12λr to 0.14λr, and the width of the feeding microstrip line 31 is 0.02λr to 0.04λr. As the length of the feeding microstrip line 31 is longer, both the high band and the low band of the antenna radiation layer 2 shift to lower frequencies, and the bandwidth becomes wider. Desirably, the length of the feeding microstrip line 31 is 20 mm, and the width of the feeding microstrip line 31 is 2.3 mm.

[0023] In this embodiment, the vehicle glass has a single-layer glass structure.

[0024] As shown in FIG. 5, in the second embodiment, the manufacturing method further includes a step of preparing a second glass plate 4 and fixing the second glass plate 4 to the first surface 11 of the first glass plate 1 so that the antenna radiation layer 2 is between the first glass plate 1 and the second glass plate 4. The first glass plate 1 is an inner layer glass plate provided toward the inside of the vehicle, and the second glass plate 4 is an outer layer glass plate provided toward the outside of the vehicle. In this embodiment, the vehicle glass has a double-layer glass structure, and the second glass plate 4 is fixed to the first surface 11 of the first glass plate 1 and covers the antenna radiation layer 2, so that the main structure of the vehicle glass is not affected and the antenna radiation layer 2 can be protected by the second glass plate 4, thereby improving the stability of the antenna performance of the vehicle glass of the present invention. Preferably, the antenna radiation layer can be protected by providing a protective cover on the first surface of the first glass plate.

[0025] As shown in Fig. 6, in the third embodiment, the manufacturing method further includes the steps of fixing a reflector 5 to the second surface 12 of the first glass plate 1, and positioning the feeding network layer 3 in the reflecting cavity of the reflector 5. The reflector 5 can be further provided to tilt the electromagnetic wave radiated by the antenna radiating layer 2 at a certain angle to radiate energy in a predetermined direction, and the reflector can be used to block one side of the antenna radiating layer 2, while the reflector 5 can also be used to fix a number of feeding microstrip lines 31. Specifically, the thickness of the reflector 5 does not exceed 10mm, which can realize weight reduction and aesthetics.

[0026] 7 and 8, curve L1 is the left rotation circular polarization gain at φ=0°, curve L2 is the left rotation circular polarization gain at φ=90°, curve L3 is the right rotation circular polarization gain at φ=0°, and curve L4 is the right rotation circular polarization gain at φ=90°. Combining these with FIG. 9, the antenna performance of the vehicle glass of the present invention is, at 1.19 GHz, the maximum gain is 4.2 dB and the S11 (echo loss) is -13.9 dB, and at 1.57 GHz, the maximum gain is 9.1 dB and the S11 (echo loss) is -27.7 dB.

The manufacturing method according to this embodiment has the same specific steps and operation principles as the manufacturing method according to embodiment 1, so duplicated descriptions will be omitted here.

[0028] 1, in an embodiment of the present invention, when the first glass plate 1 is attached to the vehicle body, the first surface 11 of the first glass plate 1 faces the outside of the vehicle, and the second surface 12 of the first glass plate 1 faces the inside of the vehicle. Therefore, the power supply network layer 3 is easily electrically connected to the receiving module in the vehicle, and the antenna radiation layer 2 is easy to receive signals.

[0029] 2, 10 and 11, the annular groove 22 may be circular, rectangular or wavy. Any of the three shapes can achieve circular polarization performance, and an appropriate shape can be selected to design the antenna radiating layer 2 based on the space that can be laid out on the first glass plate 1. Preferably, the annular groove may be formed in any combination of a circular, rectangular or wavy shape.

[0030] As shown in FIG. 2, in this embodiment, both the inner annular groove 221 and the outer annular groove 222 are circular.

[0031] As shown in FIG. 10, in the fourth embodiment, the inner annular groove 221 and the outer annular groove 222 are both wavy, that is, wavy rings formed by being surrounded by two wavy lines.

[0032] As shown in FIG. 11, in the fifth embodiment, both the inner annular groove 221 and the outer annular groove 222 are rectangular.

By providing the recess 24 or the protrusion 25 at the feeding portion, the current path of the annular groove 22 is changed to adjust the impedance bandwidth of the antenna radiation layer 2.

[0034] Specifically, the first adjustment manner is performed by having the inner annular surface of the inner annular groove 221 recessed inward along its radial direction to form at least one first inner recess 241, or the inner annular surface of the inner annular groove 221 bulging outward along its radial direction to form at least one first outer protrusion 252.

The fourth adjustment method is achieved by radially recessing the outer annular surface of the outer annular groove 222 outward to form at least one second outer recess 244. In the above four adjustment methods, any one of the first two and any one of the second two can be combined, and are not limited thereto, as long as the impedance bandwidth of the antenna radiating layer 2 can be adjusted to meet requirements.
