Description

[0002] With the continuous development of modern communication technology, the demand for efficient and reliable wireless signal transmission equipment is increasing. Metal waveguide antennas, as a type of antenna with excellent electrical performance and anti-interference capabilities, are widely used in radar, satellite communication, microwave transmission, and other fields.

[0003] In the current waveguide antenna manufacturing field, the connection between the upper and lower covers of the waveguide antenna's metal cavity is mainly achieved through bolting or welding. Bolting, however, can compromise the tightness of the waveguide antenna under long-term vibration, affecting the stability of signal transmission. Welding, another existing technology, also has significant drawbacks. Precisely controlling the amount and application location of solder during actual production is extremely difficult. Improper control can easily lead to solder flowing into the waveguide signal area. Since waveguide antenna performance requires extremely high purity and structural integrity within the metal cavity, solder intrusion interferes with normal signal transmission, reducing signal transmission efficiency and failing to meet the increasingly stringent requirements of communication technology for signal quality and transmission efficiency. Therefore, it is necessary to improve existing technologies to overcome their shortcomings. Utility Model Content

[0029] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0030] See Figures 1 to 5 This invention provides a waveguide antenna, comprising: a first waveguide cover 1 and a second waveguide cover 2, which are spliced ​​together to form multiple waveguide signal regions 3 for signal transmission between them. A joint region 4 is also provided between the first waveguide cover 1 and the second waveguide cover 2, and a connecting medium is coated on the joint region 4 to fix the first waveguide cover 1 and the second waveguide cover 2 together. Compared with bolted connections, this application achieves a fixed connection between the first waveguide cover 1 and the second waveguide cover 2 by coating the joint region 4 with a connecting medium, reducing the risk of loosening due to vibration, enhancing the overall stability of the waveguide antenna structure, and helping to maintain good signal transmission performance stably over a long period.

[0031] As a key improvement of this application, overflow grooves 5 are provided between the bonding region 4 and the adjacent waveguide signal region 3. These overflow grooves 5 are used to accommodate the connecting medium overflowing from the bonding region 4. By setting the bonding region 4 between the first waveguide cover 1 and the second waveguide cover 2, and arranging the overflow grooves 5 between the bonding region 4 and the adjacent waveguide signal region 3, this application ensures that even if the connecting medium overflows when the first waveguide cover 1 and the second waveguide cover 2 are fixed using a connecting medium, the overflow grooves 5 can accommodate it. This effectively solves the problem of connecting medium intruding into the waveguide signal region 3, thereby significantly improving the performance stability and signal transmission efficiency of the waveguide antenna. Furthermore, this solution has a simple structure, reduces the complexity of the manufacturing process, and improves the reliability and consistency of production.

[0032] like Figure 1 As shown, in this embodiment, the first waveguide cover 1 is specifically the lower cover, and the second waveguide cover 2 is specifically the upper cover. Both are the same size and are spliced ​​together vertically and vertically and fixed by a connecting medium.

[0033] See Figure 2 and Figure 5 Both the first waveguide cover 1 and the second waveguide cover 2 are provided with multiple waveguide walls 6. The number of waveguide walls 6 on the first waveguide cover 1 and the number of waveguide walls 6 on the second waveguide cover 2 are the same and correspond one-to-one. When the first waveguide cover 1 and the second waveguide cover 2 are fixedly connected, each waveguide wall 6 on the first waveguide cover 1 and each waveguide wall 6 on the second waveguide cover 2 are spliced ​​together to form multiple waveguide wall units. The waveguide signal region 3 is formed in the cavity between two adjacent waveguide wall units. By forming the waveguide signal region 3 between adjacent waveguide wall units, this application can not only avoid signal interference, but also flexibly adjust the number, size and distribution of the waveguide signal region 3 to meet the diverse performance requirements of waveguide antennas in different frequency bands and application scenarios.

[0034] Furthermore, both the first waveguide cover 1 and the second waveguide cover 2 are provided with connecting ribs 7 of the same thickness as the waveguide walls 6 on their respective covers. The number of connecting ribs 7 on the first waveguide cover 1 and the second waveguide cover 2 are the same and correspond one-to-one. The bonding region 4 is formed on the end face of the connecting rib 7 on the first waveguide cover 1 facing the second waveguide cover 2.

[0035] In some other embodiments of this utility model, multiple waveguide walls 6 and connecting ribs 7 with the same thickness as the waveguide walls 6 may be provided on only one of the first waveguide cover 1 and the second waveguide cover 2. The waveguide signal region 3 is formed in the groove between two adjacent waveguide walls 6, and the bonding region 4 is formed on the connecting rib 7; the other one can be a flat plate.

[0036] like Figure 3As shown, the connecting rib 7 includes a first rib 701 that surrounds the outer contour of the waveguide antenna and a plurality of second ribs 702 distributed in the inner area enclosed by the first rib 701. The end faces of the first rib 701 and the second rib 702 facing the second waveguide cover 2 are both set as the joint area 4. The close welding of the upper and lower connecting ribs 7 can ensure the seamless connection between the first waveguide cover 1 and the second waveguide cover 2, which not only realizes the non-leakage transmission of the waveguide antenna signal in the waveguide signal area 3, but also greatly simplifies the welding process and improves the product yield.

[0037] in, Figure 3 The image shown is a front view of the first waveguide cover 1. The black shaded area on it represents the waveguide signal region 3, and the oblique cross-sectional line on it represents the bonding region 4.

[0038] In this embodiment, both the first waveguide cover 1 and the second waveguide cover 2 are made of metal materials, such as copper and aluminum, and both the first waveguide cover 1 and the second waveguide cover 2 are integrally machined with their respective waveguide walls 6 and connecting ribs 7.

[0039] Optionally, the connecting medium is solder. After being heated, the solder adheres to the bonding area 4 and solidifies upon cooling to form a reliable connection, thereby fixing the first waveguide cover 1 and the second waveguide cover 2.

[0040] In some other embodiments of this utility model, the connecting medium can also be glue, which relies on its own adhesiveness to bond and fix the first waveguide cover 1 and the second waveguide cover 2 together.

[0041] Furthermore, one of the first waveguide cover 1 and the second waveguide cover 2 is provided with a plurality of asymmetrical positioning posts 201, and the other is provided with a plurality of positioning slots 101, the same number as the positioning posts 201. In this embodiment, there are specifically three positioning posts 201, all of which are provided on the second waveguide cover 2; there are also three positioning slots 101, all of which are provided on the first waveguide cover 1. The three positioning posts 201 are inserted one-to-one into the three positioning slots 101, which enables rapid and accurate positioning during assembly, ensuring the accurate relative positions of the first waveguide cover 1 and the second waveguide cover 2, and helping to improve assembly efficiency and product quality.

[0042] In this design, multiple waveguide slots 202 are provided on the second waveguide cover 2 at positions corresponding to each waveguide signal region 3, and the waveguide slots 202 are connected to the corresponding waveguide signal region 3 to realize the radiation or reception of electromagnetic waves.

[0043] Therefore, the waveguide antenna of this utility model, by setting a joint area 4 between the first waveguide cover 1 and the second waveguide cover 2, and arranging an overflow groove 5 between the joint area 4 and the adjacent waveguide signal area 3, can accommodate the overflow of the connecting medium when the first waveguide cover 1 and the second waveguide cover 2 are fixed with a connecting medium. This effectively solves the problem of the connecting medium intruding into the waveguide signal area 3, thereby significantly improving the performance stability and signal transmission efficiency of the waveguide antenna. Furthermore, this solution has a simple structure, reduces the complexity of the manufacturing process, and improves the reliability and consistency of production.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
