Problems solved by technology

Since the wavelength of the transmission line of general microwave frequency is relatively long, especially in the low-frequency microwave frequency band, the conventional technology leads to a relatively large volume of the adapter

Embodiment 1

[0045] Such as Figure 1~3 , Figure 4d , Figure 5a-5d shown.

[0046] A single-ridge rectangular waveguide transmission line adapter, including a transmission line 2, another transmission line 2 and an electromagnetic wave channel 3. Both ends of the electromagnetic wave channel 3 are part of a plane A and a plane B respectively. One end of each transmission line 2 communicates with one end of the electromagnetic wave channel 3 .

[0047] The transmission line adapter is very compact: the maximum length t of the microwave channel is less than 0.2 times the wavelength in free space corresponding to the central operating frequency of the microwave matching structure.

[0048] The transmission lines 2 are all single-ridge rectangular waveguides; the metal ridge 22 of the one transmission line 2 is connected to the bottom of the single-ridge rectangular waveguide transmission line 2; the metal ridge 22 of the other transmission line 2 is connected to the single-ridge rectang...

Abstract

The invention discloses a single-ridge rectangular waveguide transmission line adapter, and the adapter employs electromagnetic wave channels formed by the mutual communication of a plurality of rectangular through holes or in other shapes, so as to accord with the transmission lines of different structures. Two transmission lines are single-ridge rectangular waveguides. A metal ridge of one transmission line is connected with the bottom of the transmission line. The metal ridge of the other metal transmission line is connected with the top of the transmission line. Compared with an existing similar scheme, the adapter can remarkably improves the modeling, optimization and calculation efficiency. The size of the adapter is smaller, and the work bandwidth is larger. The adapter is mainly used in communication and radar systems of various electromagnetic waves, millimeter waves and terahertz waves.

Description

technical field [0001] The invention relates to an electromagnetic wave component, in particular to a compact transmission line adapter. Background technique [0002] In various electromagnetic wave systems, the switching problems of various transmission lines are ubiquitous. The traditional transfer between different transmission lines often adopts a multi-section transmission line matching method, and each transmission line is used as the first stage of the impedance converter, and the length is 1 / 4 of the waveguide wavelength. Since the wavelength of the transmission line of the general microwave frequency is relatively long, especially in the low-frequency microwave frequency band, the volume of the adapter is relatively large due to the conventional technology. Contents of the invention [0003] The technical problem to be solved by the invention is a compact transmission line adapter. Compared with the prior art, the structure is simpler, the processing is more conv...
