[0028] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0029] In this disclosure, unless otherwise indicated, directional terms such as "upper" and "lower" are generally defined relative to the drawing planes of the accompanying drawings, with the first direction being the vertical direction of the drawings, the second direction being the horizontal direction of the drawings, and "inner" and "outer" referring to the inside and outside of the relevant components. Furthermore, the terms "first" and "second," etc., are used solely for purposes of distinction and should not be construed as indicating or implying relative importance.

[0030] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they may refer to a fixed connection, a detachable connection, or an integral connection. They may be directly connected or indirectly connected through an intermediate medium, or they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on specific circumstances.

[0031] In-vehicle satellite communications, including GNSS, Tiantong, and future NTN satellite communications, will be a key future direction for in-vehicle communication applications. Due to limited space on vehicles and the special requirement for antennas to face the sky for coverage, current in-vehicle antenna applications and layout design requirements are very high. This is because vehicles use a large number of related components, such as metal heating elements, which are prone to interference with antennas.

[0032] In the related technology, metal heating elements can be used to heat parts that need to be heated, such as glass. Glass heating can avoid problems such as water mist on the glass. At the same time, the glass will not interfere with the signal transmission of the antenna. Therefore, the antenna is usually arranged close to the glass. However, when the antenna is close to the metal heating element, the metal heating element will cause the radiation characteristics of the antenna to deteriorate significantly, causing the antenna to fail to work normally, resulting in high limitations on the arrangement position of the antenna and inability to choose freely.

[0033] For this reason, Figure 1-Figure 2 As shown, one aspect of the present disclosure provides a metal heating element, including a main body 1 and a branch 2 , wherein the branch 2 is connected to the main body 1 , and the metal heating element 100 is close to the antenna 101 .

[0034] The main body 1 is configured to be able to conduct electricity and generate heat, and the branch 2 is configured to be able to generate current when receiving the wireless signal radiated by the antenna 101 . The current flowing on the branch 2 is in the opposite direction to the current flowing on the main body 1 .

[0035] Among them, the main body 1 and the branches 2 are both made of metal. The main body 1 can be used to heat parts that need to be heated, such as glass and other parts. It can be understood that when the main body 1 is conductive, current flows on the main body 1, and heat can be generated due to the resistance of the main body 1 itself, thereby achieving heating.

[0036] In the above technical solution, electrical conduction can be achieved by connecting the branch 2 to the main body 1. By configuring the branch 2 to generate current when receiving a wireless signal radiated by the antenna 101, and the current flowing through the branch 2 in the opposite direction to the current flowing through the main body 1 when conducting, the current flowing through the main body 1 can be offset, achieving a choke effect, thereby reducing the impact of the metal heater 100 on the radiation characteristics of the antenna 101 and improving the polarization characteristics, gain, and other performance of the antenna 101. The metal heater 100 can be placed close to the antenna 101 without affecting the performance of the antenna 101, which allows for a high degree of freedom in the placement of the antenna 101 and a wide range of options.

[0037] Optionally, in one embodiment of the present disclosure, the branch 2 can be integrally formed with the body 1, and the branch 2 is located on the side of the body 1. Of course, in other embodiments, the branch 2 can also be fixed to the body 1 by welding.

[0038] Optionally, in one embodiment of the present disclosure, the main body 1 extends along a first direction, and the branch 2 at least partially extends along the first direction and is spaced apart from the main body 1. By having at least a portion of the branch 2 extend in the same direction as the main body 1, the branch 2 can generate a current in the opposite direction to that flowing on the main body 1 when receiving a wireless signal radiated by the antenna 101, that is, it can generate a reverse current, thereby achieving a current cancellation effect and a choking effect.

[0039] In some examples, a portion of the branch 2 extends along the first direction and is spaced apart from the body 1. It should be noted that the portion of the branch 2 extending along the first direction may be parallel to the body 1 or may be inclined at a certain angle to the body 1. In other examples, the entire branch 2 extends along the first direction and is spaced apart from the body 1. It should be noted that the branch 2 may be parallel to the body 1 or may be inclined at a certain angle to the body 1.

[0040] Optionally, in one embodiment of the present disclosure, the branch 2 has a first end and a second end, the first end being connected to the body 1, and the second end being an open end. By setting the second end of the branch 2 as an open end, the branch 2 constitutes an open-circuit branch 2, which can facilitate the realization of reverse current. It should be noted that the second end being set as an open end means that the second end of the branch 2 is not connected to any other structure.

[0041] Optionally, in one embodiment of the present disclosure, the length from the first end to the second end of the branch 2 is set to one-quarter of the wavelength of the operating frequency of the antenna 101. This configuration can facilitate resonance of the branch 2 when receiving the wireless signal radiated by the antenna 101, thereby generating a reverse current, thereby canceling the current in the body 1.

[0042] The length from the first end to the second end can be set according to the specific operating frequency wavelength of antenna 101. In other words, the length from the first end to the second end of branch 2 will vary depending on the specific operating frequency of antenna 101. It should be noted that the length from the first end to the second end of branch 2 refers to the entire length of branch 2, that is, the length extending from the first end of branch 2 to the second end of branch 2 along the extension direction of branch 2.

[0043] Optionally, in one embodiment of the present disclosure, a branch 2 is provided on at least one side of the body 1 in the second direction, the body 1 extends along the first direction, the number of the branch 2 is multiple, and the multiple branch 2 are spaced apart along the first direction. The first direction and the second direction are arranged at an angle.

[0044] The main body 1 extends along a first direction, and a plurality of branches 2 are spaced apart along the extension direction of the main body 1. Since the metal heater 100 is at a certain distance from the antenna 101, and the wireless signal radiated by the antenna 101 is radiated outward in an open manner, at least most positions of the metal heater 100 will affect the antenna 101. Therefore, the multiple branches 2 can offset the current flowing at different positions of the metal heater 100, thereby reducing the impact of the metal heater 100 on the radiation characteristics of the antenna 101.

[0045] In the first direction, the spacing between two adjacent branches 2 may be equal or unequal. In some examples, a branch 2 is provided on one side of the body 1, and no branch 2 is provided on the other side of the body 1.

[0046] Optionally, in one embodiment of the present disclosure, branches 2 are provided on both sides of the main body 1 in the second direction, and the multiple branches 2 on both sides of the main body 1 in the second direction are symmetrically arranged with the axis of symmetry of the main body 1 extending along the first direction as the symmetry axis. This arrangement can produce a balancing effect, so that the branches 2 on both sides of the main body 1 can generate reverse currents to offset the current in the main body 1, thereby better reducing the impact of the main body 1 on the radiation characteristics of the antenna 101.

[0047] Optionally, in another embodiment of the present disclosure, branches 2 are provided on both sides of the second direction of the main body 1, and multiple branches 2 on both sides of the second direction of the main body 1 are staggered. This arrangement can also improve the offset effect of the current on the main body 1.

[0048] Optionally, in one embodiment of the present disclosure, the shape of the branch 2 is set to be strip, rectangular, square, circular or stepped. The shape of the branch 2 can be set according to actual needs and is not limited here.

[0049] In some examples, the shape of the branch 2 is set to be rectangular, and the rectangle can be directly connected to the main body 1. A connector can also be provided on the rectangle, and connected to the branch 2 through the connector, wherein the length of the rectangle is set to one-quarter of the wavelength of the working frequency of the antenna 101. In other examples, the shape of the branch 2 is set to be square, and the square can be directly connected to the main body 1. A connector can also be provided on the square, and connected to the branch 2 through the connector, wherein the length of the square is set to one-quarter of the wavelength of the working frequency of the antenna 101. In other examples, the shape of the branch 2 is set to be circular, and the circle can be directly connected to the main body 1. A connector can also be provided on the circle, and connected to the branch 2 through the connector, wherein the diameter of the circle is set to one-quarter of the wavelength of the working frequency of the antenna 101. In other examples, the shape of the branch 2 is set to be stepped, and the stepped shape can be directly connected to the main body 1. A connector can also be provided on the stepped shape, and connected to the branch 2 through the connector, wherein the overall length of the stepped shape is set to one-quarter of the wavelength of the working frequency of the antenna 101.

[0050] Optionally, in one embodiment of the present disclosure, the branch 2 is configured as a strip structure, comprising a first segment 21 and a second segment 22 connected end to end, wherein the end of the first segment 21 facing away from the second segment 22 is configured as the first end, and the first segment 21 extends along the second direction, and the end of the second segment 22 facing away from the first segment 21 is configured as the second end, and the second segment 22 extends along the first direction. The first direction and the second direction are arranged at an angle. This arrangement allows a portion of the branch 2 to extend along the first direction, generating a reverse current, thereby facilitating connection between the branch 2 and the body 1.

[0051] The first section 21 and the second section 22 are both strip-shaped structures. The ends of the first section 21 and the second section 22 that are closest to each other are connected and can be integrally formed. The end of the first section 21 that is away from the second section 22 is connected to the body 1. Therefore, the first section 21 is primarily used for connection to the body 1, while the second section 22 is primarily used for generating reverse current. In some examples, the first direction is perpendicular to the second direction, that is, the first section 21 is perpendicular to the body 1. In other examples, the first direction and the second direction may be arranged at an acute angle, that is, the first section 21 is inclined relative to the body 1.

[0052] Optionally, in one embodiment of the present disclosure, the length of the second segment 22 in the first direction is greater than the length of the first segment 21 in the second direction. This configuration can reduce the size of the metal heater 100 in the second direction while enabling the branch 2 to generate a reverse current, thereby reducing the impact of the main body 1 on the antenna 101.

[0053] Optionally, in some examples, the body 1 may be a metal wire that can conduct electricity and generate heat.

[0054] A second aspect of the present disclosure further provides an antenna assembly comprising an antenna 101 and the aforementioned metal heating element 100, wherein the antenna 101 and the metal heating element 100 are positioned close to each other. The metal heating element 100 does not affect the radiation characteristics of the antenna 101, thereby improving the polarization characteristics, gain, and other performance of the antenna 101. This allows for a wide range of placement options for the antenna 101, allowing it to be placed wherever desired.

[0055] In some examples, the antenna 101 is located below the metal heating element 100 .

[0056] A third aspect of the present disclosure further provides a glass assembly comprising a glass body 1 and the aforementioned metal heater 100. The metal heater 100 is connected within the glass body 1 and is capable of heating the glass body 1. The metal heater 100 is configured to heat the glass body 1. In some examples, there may be multiple metal heaters 100, each spaced apart and arranged in parallel. The antenna 101 may be positioned below the glass assembly to avoid interference from the metal heater 100.

[0057] A fourth aspect of the present disclosure further provides a vehicle, comprising the above-mentioned metal heating element 100 , or the above-mentioned antenna assembly, or the above-mentioned glass assembly.
