Embodiment 1

[0038] see figure 2 , in this embodiment, the substrate 1 can be along the first axis (such as Figure 4 As shown, in this embodiment, the first axis is the X axis, and the direction of the first axis is the X axis direction) is slidably installed in the carrier board 2 . The substrate 1 is provided with a first input microstrip line 3, a first output microstrip line 4, a second output microstrip line 5, a first branch microstrip line 6 and a second branch microstrip line 7, the first branch microstrip line The line 6 and the second branch microstrip line 7 are arranged parallel to each other, and the extension directions of the first branch microstrip line 6 and the second branch microstrip line 7 are all perpendicular to the first axis direction; the first input microstrip line 3, the second branch microstrip line A branch microstrip line 6 and the first output microstrip line 4 are connected in sequence, and the first input microstrip line 3 , the second branch microstrip...

Embodiment 2

[0048] The structure of the substrate 1 and the carrier plate 2 of this embodiment is basically the same as that of Embodiment 1, the difference is, see Figure 13 , also includes a first metal casing 17, the side of the first metal casing 17 has holes, and the base plate 1 and the carrier plate 2 are horizontally suspended in the first metal casing 17. The above suspension structure is one of the methods in the radio frequency signal transmission technology.

[0049] The structure in Embodiment 1 is an open transmission system. In Embodiment 2, no copper clad layer is provided on the reverse side of the substrate 1, and the first metal shell 17 is used to replace the function of the copper clad layer. The advantage of this embodiment is that the first metal shell 17 is The interaction between the substrate 1 and the carrier plate 2 provides a stable magnetic field range, which protects the substrate 1 and the carrier plate 2 from interference from external factors, and the st...

Embodiment 3

[0051] The structure of the substrate and carrier plate of this embodiment is basically the same as that of Embodiment 1, the difference is, see Figure 14 , the base plate 1 and the carrier plate 2 are horizontally suspended in the first metal shell 17 . The substrate only includes individual microstrip lines, which can be regarded as a whole metal structure, and compared with Embodiments 1 and 2, the PCB material bottom plate 15 is omitted. The substrate 1 is a monolithic metal structure, and forms a splitter structure together with the first metal shell 17 . The all-metal structure increases the allowable power capacity of the base plate 1 and the carrier plate 2 when they work, and cooperates with the mutual movable working mode to improve the use safety of the structure and greatly enhance the use efficiency. In practical application, the base plate 1 can be mounted in a suspended position (the mounting structure is not shown in the figure) in the first metal shell 17 , ...

Abstract

The invention discloses a power divider with variable port current amplitudes and an antenna. The power divider comprises a substrate and a carrier plate; and the substrate can be installed in the carrier plate in a sliding manner along a first axis. A first input microstrip line, a first output microstrip line, a second output microstrip line, a first branch microstrip line, and a second branch microstrip line are arranged on the substrate; a first adjustment microstrip line is arranged on the carrier plate; and when the substrate slides along the first axis direction, the overlapped width ofthe first adjustment microstrip line and the first branch microstrip line can be adjusted. According to the invention, after the carrier plate moves, the input impedance of the power divider and power amplitudes and phases of all output ports can be adjusted. When the power divider is in use, the widths of the microstrip lines can be adjusted and antenna structures with different load impedancescan be connected. Besides, the antenna manufactured by using the power divider with variable port current amplitudes enables flexibility of adjustment of indexes like the antenna wave beam to be enhanced.

Description

technical field [0001] The invention relates to the technical field of radio frequency devices, in particular to a variable port current amplitude power divider and an antenna using the port current amplitude variable power divider. Background technique [0002] The full name of the power divider is the power divider, and the English name is Power divider. It is a device that divides the energy of one input signal into two or more outputs with equal or unequal energy. It can also conversely synthesize the energy of multiple signals into one output. It can also be called a combiner. A certain degree of isolation should be guaranteed between the output ports of a power divider. According to the output, the power divider is usually divided into one divided into two (one input and two outputs), one divided into three (one input and three outputs) and so on. The main technical parameters of the power splitter are power loss (including insertion loss, distribution loss and refle...
