Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0035] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the relationship between the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly.

[0036] In addition, if there are descriptions involving "first", "second" and so on in the...

Abstract

The invention discloses a waveguide coaxial converter, which comprises: a device body, an excitation terminal and a feed source terminal are arranged in the device body; a second ridge wave conductor and a first ridge wave conductor, and the second ridge wave conductor and the first ridge wave conductor are alternately located in the device body along the direction from the excitation end to the feed source end, and the second ridge wave conductor and the first ridge wave conductor are provided with matching structures; A short circuit board, the short circuit board is located in the device body close to the excitation end, and a zigzag short circuit rear cavity is formed between the short circuit board and the matching structure. The technical scheme of the present invention optimizes the structure between the double-ridge waveguide and the short circuit board, realizes the broadband and dual-polarization design of the waveguide-coaxial converter; solves the insufficient bandwidth of existing products, and can realize a relative bandwidth of more than 30% .

Description

technical field [0001] The invention relates to the technical field of converters, in particular to a waveguide coaxial converter. Background technique [0002] The waveguide coaxial converter is an indispensable passive conversion device in various radar systems, precision guidance systems, electronic countermeasure systems, communication systems and test equipment. In the microwave field, waveguide-to-coaxial converters are relatively mature and widely used. However, with the development of antenna unit forms and phased array antenna systems, there are new requirements for the size interface of waveguide-to-coaxial converters. [0003] However, most existing waveguide-to-coaxial converters have a relatively narrow bandwidth; and the relative bandwidth of the current related products is 10%, which cannot meet the large-capacity and wide-band requirements of the new generation communication system. Contents of the invention [0004] The main purpose of the present inventi...
