The T-shaped waveguide ridge 8 means that the waveguide ridge is arranged in a T-shape on one side wall of the T-shaped ridge waveguide 7. At least one T-shaped waveguide ridge 8, disposed on the first waveguide wall and/or the second waveguide wall, means that when the number of T-shaped waveguide ridges 8 is one, the waveguide ridge may be disposed on the first waveguide wall or on the second waveguide wall; when the number of the T-shaped waveguide ridges 8 is two, the two T-shaped waveguide ridges are provided on the first waveguide wall and the second waveguide wall, respectively. Meanwhile, the T-shaped waveguide ridge 8 in the present embodiment is disposed at the middle position of the side wall of the T-shaped ridge waveguide 7, specifically, when the number of the T-shaped waveguide ridges 8 is one, the T-shaped waveguide ridge 8 is disposed on the first side or the second side wall of the T-shaped ridge waveguide 7; when the number of the T-shaped waveguide ridges 8 is two, two T-shaped waveguide ridges are respectively provided on two side walls of the T-shaped ridge waveguide 7 in the center.

Wherein the second ridge 5 has two sides which are parallel to each other so that the second ridge 5 has the same width from where it meets the first ridge 4 to the first port.
The first ridge 4 gradually decreases from the two ends of the first ridge 4 to the middle, which means that the first ridge 4 is arranged in a structure with gradually changing width.
The matching degree of input impedance and output impedance in the ridge waveguide power divider has a large influence on scattering parameters of the power divider, and in order to enable a circuit to have good transmission characteristics and obtain excellent return loss and insertion loss, the impedance of an input end and an output end of the power divider needs to be matched.
It can be known that the output impedance of the power divider formed by the three-port T-shaped ridge waveguide is formed by connecting the impedances of the two branches of the T-shaped ridge waveguide in parallel (when the power divider is used as a combiner, the impedances of the two branches are connected in parallel to form the input impedance of the combiner), so that the first ridge 4 and the second ridge 5 in this embodiment are arranged in different structures so as to enable the input end and the output end of the power divider formed by the T-shaped ridge waveguide and the T-shaped ridge waveguide to form impedance matching, so that the circuit structure of the power divider has good transmission characteristics, and excellent return loss and insertion loss are obtained.
As an alternative embodiment of the present embodiment, the structure of the first ridge portion 4 and the second ridge portion 5 may be provided by adopting the following structure:
setting the width of the second ridge portion 5 to a standard width; the first ridge portion 4 is set to a standard width at both ports, and then the first ridge portion 4 is set stepwise from both ports toward the middle to assume a structure of gradually changing width.
In this embodiment, the width of the common port of the power splitter is not adjusted, that is, the width of the second ridge 5 of the T-shaped waveguide ridge is set to be the same as the width of the common port, and is set to be the standard width, so that the input port has the standard impedance characteristic. The impedance of the output port of the power divider is formed by connecting the impedances of the two branches in parallel, and when the two branches have standard impedance, the impedance of the output port formed by connecting the two branches in parallel is necessarily smaller than the impedance of the common end, so that the impedance of the output end is adjusted by changing the width of the waveguide ridge of the branches. Since the smaller the width of the waveguide ridge, the greater the impedance of the waveguide ridge, the impedance characteristics of the branch end of the T-shaped ridge waveguide are improved by providing the first ridge portion 4 with a structure in which the width is gradually changed, so that the impedance of the branch port formed matches the impedance of the common port.
Optionally, the specific method for setting the width of the first ridge 4 in a gradual change manner includes:
the third side of the first ridge 4, which is connected with the second ridge 5, is arranged in a plane, and the fourth side, which is far away from the second ridge 5, is arranged in a step shape, wherein,
the first ridge 4 is provided with an initial step at the middle position of the fourth side surface, and at least two steps are symmetrically arranged at two sides of the initial step.
Wherein, the one side of the first ridge portion 4 is arranged in a ladder shape, so that the impedance characteristic of the circuit can be conveniently adjusted. An initial step is arranged in the middle of the side surface of the first ridge part 4 provided with the steps, and a plurality of steps are respectively arranged on the two sides of the initial step in a symmetrical arrangement mode. In order to adjust the impedance of the branch port of the power divider formed by the first ridge 4 to a desired state, in this embodiment, two steps are respectively disposed on two sides of the initial step of the first ridge 4, and the steps on two sides of the initial step are symmetrically disposed on two sides of the initial step, wherein the length of the first step connected to the initial step is less than the length of the second step connected to the other side of the first step, and the step height between the first step and the initial step is greater than the step height between the second step and the first step.
In the present embodiment, the influence of different step heights on the scattering parameter of the equivalent circuit in the process of adjusting the impedance of the output end by changing the gradual change width of the T-shaped waveguide ridge and performing impedance matching is described with reference to a specific example. As shown in fig. 2, which is a graph showing the effect of simulating the return loss of the circuit when the first step and the initial step have different step heights, in the graph, S1 represents the step height between the first step and the initial step, S (1,1) represents a return loss curve, x-axis represents the frequency of a transmission signal, and y-axis represents a return loss value, and as can be seen from fig. 2, when S1 is 0.5mm, the obtained return loss curve has a higher return loss in a low frequency band and a lower return loss in a high frequency band; when S1 is 1.5mm, it has a lower return loss in the low frequency band and a higher return loss in the high frequency band; when S1 is 1mm, the return loss is lower than-22 dB in the full frequency band, and the performance is best.
Fig. 3 is a simulated return loss diagram of a circuit in the case where the second step and the first step have different step heights when S1 is 1mm, in the diagram, S2 denotes the step height of the second step and the first step, S (1,1) denotes a return loss curve, the x-axis denotes the frequency of a transmission signal, the y-axis denotes the return loss value, the uppermost curve in the diagram is the return loss curve corresponding to S2 being 0.6mm, the middle is the return loss curve corresponding to S2 being 0.4mm, and the lowest is the return loss curve corresponding to S2 being 0.2mm, it can be seen that the smaller the S2 parameter is, the better the obtained return loss performance is.
In consideration of the difficulty of actual processing, in an optional implementation manner of this embodiment, the length of the initial step is set to 3.0000mm, and the length of the first step is set to 3.500 mm; the step height of the initial step and the first step is set to be 0.8000mm, and the step height of the second step and the first step is set to be 0.2000 mm. The step height of the initial step and the lengths of the two second steps can be obtained correspondingly according to the size of the adopted standard ridge waveguide, and the length of the step and the step height.
