Embodiment 1

[0044] like Figure 1a and Figure 1b shown.

[0045] A compact three-port network connected by tangential planes, comprising at least three transmission lines 2, and an electromagnetic channel 3; the two ends of the electromagnetic channel 3 are respectively part of a plane A and a plane B; the transmission lines 2 respectively pass through one of its transverse The cross section communicates with one of the two end faces of the electromagnetic passage 3; the electromagnetic passage 3 is formed by a branch, and the electromagnetic wave branch is composed of five through holes 31 communicated along the Y direction;

[0046] In order to achieve a compact design, the maximum length t of the electromagnetic channel is less than 0.3 times the wavelength in free space corresponding to the central operating frequency of the compact three-port network.

[0047] The three transmission lines 2 communicate with one of the two end faces of the electromagnetic channel 3 through one cross...

Embodiment 2

[0053] like Figure 2a and Figure 2b shown.

[0054] Compared with the implementation example 1, the main difference between this implementation example is that the one transmission line 2 is a double-ridge rectangular waveguide, and the other two transmission lines 8 are rectangular waveguides.

Abstract

The invention discloses a compact three-port network with a communicated tangent plane, comprising at least three transmission lines and at least one electromagnetic channel. The two end surfaces of the electromagnetic channel are respectively a part of a plane A and a plane B. The three transmission lines are communicated with one of the two end faces of the electromagnetic channel through one tangent plane. The electromagnetic channel is composed of at least one branch. At least one electromagnetic wave branch is composed of at least three through holes which are communicated in the Y direction. The invention is advantageous in that in a very short distance, the compact broadband matching from one transmission line to another transmission line can be realized. The invention is mainly applied to various communication and radar systems of microwave, millimeter wave and terahertz wave bands.

Description

technical field [0001] The invention relates to an electromagnetic wave element, in particular to an electromagnetic wave structure for matching and communicating one transmission line with the other two transmission lines. Background technique [0002] In various electromagnetic wave systems, forked connections between transmission lines are ubiquitous. The signal in the transmission line will be reflected due to the parasitic effect introduced by the bifurcation. In order to realize the matching of the compact three-port network, a matching circuit needs to be set on the transmission line. [0003] The existing matching circuit has complex structure, large volume, and narrow bandwidth, especially in rectangular waveguides, single-ridge rectangular waveguides, double-ridge rectangular waveguides and four-ridge rectangular waveguides, circular waveguides or elliptical waveguides, single-ridge circular waveguides or elliptical waveguides, In the bending connection of double...
