Embodiment 1

[0026] Such as figure 1 As shown, the loaded type H-plane equal-phase power divider includes a coupling cavity 7, an input and output terminal connected to the coupling cavity 7, that is, an input port 1 connected to the coupling cavity 7, an output port A3, an output port B5, and an isolation port A2, isolated port B4, isolated port C6. The input port 1, the isolation port B4, and the isolation port C6 are located at the front end of the coupling cavity 7, and the isolation port A2 is located at the rear end of the coupling cavity 7. The front end and the rear end are two opposite sides of the coupling cavity 7, and the isolation ports B4 and The isolation port C6 is located on both sides of the input port 1, the output port A3 and the output port B5 are respectively located on both sides of the isolation port A2; the coupling cavity 7 is provided with 19 columns 10, and the 19 columns 10 are arranged in an H shape. The bodies 10 are arranged in 6 rows along the front-to-bac...

Embodiment 2

[0032] Such as figure 2 As shown, the only difference from Embodiment 1 is that the coupling cavity 7 has a protrusion on its width, and the direction of the protrusion points into the coupling cavity. Only 2 cylindrical columns 10 and 2 rectangular columns 10 are used. The loading conductor ridge 9 and metal ridge 8 are connected together without matching waveguide 11 . There is a gap greater than zero between adjacent columns 10 along the front-back axis of the input port 1 .

[0033] The above are examples only. In actual production, the side of the coupling cavity 7 can be one or more straight line segments, or a smooth curve, forming a rectangle, trapezoid or other more complex figures in the top view direction. The columnar body 10 can be rectangular, circular, elliptical, or other irregular shapes.

Abstract

The invention discloses a loaded H-plane equiphase power divider. The loaded H-plane equiphase power divider comprises a coupling cavity, an input port, output terminals and three isolation terminals, wherein the input port, the output terminals and the three isolation terminals are communicated with the coupling cavity; the input port and two isolation terminals are located at a front end face of the coupling cavity, and the other isolation terminal and the output terminals are located at a rear end face of the coupling cavity; and columnar bodies are arranged in the coupling cavity, are arranged into at least three rows along the direction of the front-rear axis of the input port, are arranged into at least two columns along the direction vertical to the front-rear axis of the input port, and are connected with an upper internal wall or lower internal wall of the coupling cavity. The power divider disclosed by the invention has the advantage of phase coincidence and has the characteristics of simple structure, small volume and low processing difficulty. The loaded H-plane equiphase power divider can be widely applied to the military and civilian fields of antenna arrays, phased-array radar, power synthesis, missile guidance, communications and the like.

Description

technical field [0001] The invention relates to a power divider. Specifically, it relates to a broadband two-way power splitter loaded with multiple columns, that is, a loaded H-plane equiphase power splitter. Background technique [0002] The power splitter is a common component in modern microwave communication and military electronic systems. Due to its high power capacity and low insertion loss, waveguide power splitters are widely used. The two-way waveguide power splitter can be used alone, or can be connected in series to form a multi-way power splitting network, which is used in the fields of phased array radar, antenna array, and power combination. The existing two-way waveguide power splitter mainly includes E-plane T-shaped branch, H-plane T-shaped branch, waveguide magic T, H-plane waveguide crack bridge, etc. Among them, due to the low isolation between the two output terminals of the first two devices, the mismatch of any output port will seriously affect th...
