[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0035] In this invention, unless otherwise expressly specified and limited, "above or below" the first feature may include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on" the first feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the first feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] like Figures 3 to 6 As shown, a conductor includes a branch conductor 2 connected to a main conductor 1. The main conductor 1 has a height of H1 and a width of W1, and the branch conductor 2 has a height of H2 and a width of W2, where H1 > W1 and H2 > W2. Prior art is a wire conductor (see...). Figure 1 and Figure 2The height of the conductor is less than its width, resulting in a flat overall structure and a large planar dimension of the conductor. Furthermore, chamfering is required at the corners to achieve impedance matching, causing unnecessary difficulties in production. This invention, however, allows the conductor's height to be greater than its width, significantly reducing the planar dimension of the conductor. It also eliminates the need for chamfering at the corners, simplifying the manufacturing process. Moreover, the power combining device using this conductor can also have its planar dimension significantly reduced, facilitating equipment miniaturization.

[0037] Furthermore, H1=H2, W1=W2, see Figure 3 and Figure 4 .

[0038] Furthermore, to extend the bandwidth, H1 > H2, W1 = W2, see [link / reference]. Figure 5 and Figure 6 .

[0039] Furthermore, to achieve good electromagnetic performance, the branch conductor 2 is centrally positioned along the height of the main conductor 1, meaning the distance from the branch conductor 2 to the upper and lower surfaces of the main conductor 1 is equal. Figure 5 and Figure 6 .

[0040] Furthermore, in order to obtain good electromagnetic performance, the length of the branch conductor 2 is nλ / 4, where n is an odd number, so its length can be flexibly selected according to the actual situation.

[0041] A strip wire, the strip wire comprising the conductor.

[0042] A power combining device, the power combining device including the strip.

[0043] In summary and according to Figures 7 to 9 As can be seen from the simulation curve, the conductor structure of this utility model is simple and easy to process and manufacture, which can significantly reduce the planar size of the strip. The power combining device using this strip can also have its planar size significantly reduced, which is conducive to the miniaturization of the equipment. Furthermore, its electromagnetic performance is good and it is suitable for widespread use.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
