[0020] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0021] like Figure 1 As shown, this utility model provides an integrated lightweight vehicle antenna, comprising:

[0022] The base plate 1 and multiple carrier plates 2 are integrally formed on the base plate 1. A first antenna trace layer is provided on the surface of the base plate 1 and the carrier plates 2. The first antenna trace layer includes a laser-engraved circuit layer and a first chemically plated trace layer arranged sequentially from the inside to the outside. A first antenna vibrator layer is provided on the surface of the base plate 1 and the carrier plates 2. The first antenna vibrator layer is connected to the first antenna trace layer. The first antenna vibrator layer includes a laser-engraved vibrator layer and a first chemically plated vibrator layer arranged sequentially from the inside to the outside.

[0023] The outer shell has an internal cavity, and the base plate is fixed inside the cavity.

[0024] Specifically, to address the issues of poor integration and lightweighting in existing vehicle-mounted antennas, this utility model provides an integrated lightweight vehicle-mounted antenna with multiple carrier plates 2 integrally formed on a base plate 1. A first antenna trace layer and a first antenna vibrator layer are provided on the base plate 1 and carrier plates 2, forming an integrated distribution and molding of multiple antennas, as well as the molding and connection of traces. The first antenna trace layer and the first antenna vibrator layer respectively include a laser-engraved circuit layer and a first electroplated trace layer, and a laser-engraved vibrator layer and a first electroplated vibrator layer. Compared to the traditional method of soldering individual antennas onto a PCB board, this integrated lightweight vehicle-mounted antenna is lighter and has a simpler manufacturing process, which is beneficial for lightweight design.

[0025] Furthermore, the base plate 1 can be a one-piece design or a split design; for a one-piece base plate 1, all the bearing plates 2 are integrally formed on the same base plate 1; for a split base plate 1, the base plate 1 can be set with two, three, etc., and several bearing plates 2 are integrally formed on each base plate 1.

[0026] In this embodiment, as Figure 1 As shown, the base plate 1 is a split design, and the three-section split design is collectively referred to as base plate 1; in another embodiment, the three-section split base plate 1 can be a single, whole base plate 1.

[0027] Furthermore, the integrated lightweight vehicle antenna has an outer shell, and the base plate 1 can be fixed inside the shell with fasteners, integrating all types of antennas into the same shell.

[0028] Optionally, the first antenna element layer is provided with multiple elements, including various types of antennas.

[0029] Specifically, multiple first antenna elements can be set on the carrier plate 2 or on the base plate 1. There are multiple types of antennas in the multiple first antenna elements, and the number of each type of antenna can also be set as needed.

[0030] In this embodiment, multiple antennas include V2X antenna 5, 5G antenna 6, WIFI antenna 7, RKE antenna 8, UWB antenna 9, and AMFM antenna 10; wherein there are two V2X antennas 5, four 5G antennas 6, one WIFI antenna 7, one RKE antenna 8, one UWB antenna 9, and one AMFM antenna 10, and one antenna is provided on each carrier plate 2, and the AMFM antenna 10 is provided on the base plate 1.

[0031] Furthermore, the support plate 2 can be a vertical plate, or it can be an L-shaped plate, U-shaped plate, or other shaped plate integrally formed and connected to the base plate 1.

[0032] Optionally, it also includes a circularly polarized antenna, which is connected to the base plate 1.

[0033] Specifically, the use of circularly polarized antennas further enriches the variety of antennas and improves integrated design.

[0034] Optionally, at least two circularly polarized antennas are provided, including at least a navigation antenna and a satellite digital audio broadcasting antenna.

[0035] Specifically, the navigation antenna is either a GPS antenna 3 or a GNSS antenna, and the satellite digital audio broadcasting antenna is an SDARS antenna 4.

[0036] In this embodiment, one navigation antenna and one satellite digital audio broadcasting antenna are provided, and the navigation antenna is GPS antenna 3.

[0037] Optionally, each circularly polarized antenna includes a substrate, and a second antenna vibrator layer is disposed on the surface of the substrate. The second antenna vibrator layer includes an electroplated vibrator layer and a second chemically plated vibrator layer disposed sequentially from the inside to the outside.

[0038] Specifically, navigation antennas and satellite digital audio broadcasting antennas are circularly polarized antennas, which traditionally use ceramic antennas and weigh over 100 grams. This integrated lightweight vehicle antenna can use a plastic substrate, and the circularly polarized antenna can be made on the substrate by surface roughening, electroplating and chemical plating, which can effectively reduce weight and achieve lightweight design.

[0039] Optionally, each circularly polarized antenna further includes a second antenna trace layer disposed on the surface of the substrate. The second antenna trace layer is connected to the second antenna vibrator layer and the first antenna trace layer. The second antenna trace layer includes an electroplated trace layer and a chemically plated trace layer disposed sequentially from the inside to the outside.

[0040] Specifically, traditional ceramic antennas are connected to the base plate 1 via additional metal pins. In this integrated lightweight vehicle antenna, the circular polarized antenna can eliminate the pins. The second antenna trace layer is directly created below the circular polarized antenna through surface roughening, electroplating, and chemical plating, and then connected to the base plate 1, further reducing weight and improving lightweight design.

[0041] Optionally, the base plate 1 and the support plate 2 are made of LDS plastic.

[0042] Specifically, the base plate 1 and the carrier plate 2 can adopt an LDS plastic injection molding structure, which is integrally molded and lighter than the PCB board. It is also easy to form a laser-engraved circuit layer and a laser-engraved oscillator layer through laser engraving, so as to achieve lightweight molding of the traces and oscillators.

[0043] Alternatively, the substrate material can be metallizable plastic.

[0044] Specifically, the substrate is made of metallizable plastic material, which facilitates metallization treatment on its surface, thereby making it easier to form the second antenna vibrator layer and the second antenna trace layer on the substrate.

[0045] In this embodiment, the substrate material is PPO or PPE.

[0046] The manufacturing method of the integrated lightweight vehicle antenna provided by this utility model includes:

[0047] Provides an integrally molded base plate 1 and multiple load-bearing plates 2;

[0048] Laser engraving is performed on the base plate 1 and the bearing plate 2 to form a laser-engraved circuit layer and a laser-engraved oscillator layer.

[0049] The first electroplated trace layer and the first electroplated oscillator layer are formed by electroplating on the laser-engraved circuit layer.

[0050] Specifically, the aforementioned integrated lightweight vehicle antenna base plate 1 and multiple carrier plates 2 are made of plastic through injection molding, which can reduce weight compared to traditional PCB boards and the method of installing antenna vibrator support plates, antenna vibrators and other components on them; laser engraving is used to form laser engraved circuit layers and laser engraved vibrator layers on the base plate 1 and carrier plates 2, so that the first electroplated wiring layer and the first electroplated vibrator layer can be formed on the laser engraved circuit layer and the laser engraved vibrator layer through electroplating, and components and wire harnesses can also be welded.

[0051] Optionally, when the integrated lightweight vehicle antenna also includes a circularly polarized antenna, the manufacturing method of the integrated lightweight vehicle antenna further includes:

[0052] The substrate of the circularly polarized antenna is roughened.

[0053] An electroplating layer is formed on the substrate surface;

[0054] A chemical plating layer is formed on the surface of the electroplated layer;

[0055] The electroplated oscillator layer, the second electroplated oscillator layer, and the electroplated trace layer and the second electroplated trace layer connected to the two are formed by laser engraving on the chemical plating layer and the electroplated layer.

[0056] The second plating trace layer is connected to the first plating trace layer.

[0057] Specifically, for circularly polarized antennas such as GPS antenna 3 and SDARS antenna 4, the traditional method is to use ceramic antennas connected to the base plate 1 via metal pins. In the manufacturing of this integrated lightweight vehicle antenna, a plastic substrate can be used for plastic metallization treatment. Through surface roughening, electroplating, and chemical plating, complete electroplating and chemical plating layers are formed. Then, the unwanted electroplating and chemical plating layers are removed by laser engraving. The remaining part forms the second antenna vibrator layer and the second antenna wiring layer. It is equivalent to directly making the pins through electroplating and chemical plating processes to achieve connection with the first antenna wiring layer. The connection can be made by conductive bonding, welding, etc., without the need to specially set metal pins.

[0058] In summary, the integrated lightweight vehicle-mounted antenna provided by this utility model integrates a base plate 1 and multiple carrier plates 2 directly through injection molding, integrating a V2X antenna 5, a 5G antenna 6, a WIFI antenna 7, an RKE antenna 8, a UWB antenna 9, and an AMFM antenna 10 onto the base plate 1 and carrier plates 2. A second antenna element with a second antenna trace layer is manufactured using a plastic substrate and electroplating or chemical plating layers, thereby completing the manufacturing of circularly polarized antennas such as navigation antennas and satellite digital audio broadcasting antennas, and facilitating their connection to the substrate. This design not only has a high degree of integration but also effectively reduces the weight of the entire antenna, achieving a very lightweight design.

[0059] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
