Summary of the invention
For solve the size that existing waveguide coaxial converter exists big, be not easy to processing and manufacturing and problem such as can't in experiment, finely tune, the present invention provides a kind of minimized wide-band quadrature formula waveguide coaxial converter.
Technical solution of the present invention is following:
Minimized wide-band quadrature formula waveguide coaxial converter comprises standard rectangular waveguide 1, and the sealing of one of which end is short-circuit end 2, other end opening; Side broadside in standard rectangular waveguide 1 is provided with a coaxial fitting 3, the electromagnetic field transmission direction quadrature in the axial and standard rectangular waveguide 1 of coaxial fitting 3; The inner wire 4 of coaxial fitting 3 is deep into standard rectangular waveguide 1 inside, and its end connects a metal roundlet platform 5, and the inner wire of metal roundlet platform 5 and coaxial fitting 3 is concentric; Opposite side broadside in standard rectangular waveguide 1 is provided with 5 metal matched columns 6 that are quincunx distribution;
It is that quarter-wave is led height that the inner wire 4 of coaxial fitting 3 is deep into the standard rectangular waveguide 1 inner degree of depth;
The diameter of the metal roundlet platform 5 of inner wire 4 ends of coaxial fitting 3 is about within the coaxial fitting 1.4 times of conductor diameters, highly is about quarter-wave and leads height;
The diameter of each metal matched column 6 is between coaxial fitting 3 inner wires, 4 diameters and metal roundlet platform 5 diameters between the two;
The height of each metal matched column 6 is slightly less than quarter-wave and leads height.
The present invention adopts a kind of frame mode of " the plum blossom village " shape matched column completely newly, is designed to a truncated conical shape to introducing the inner coaxial inner conductor end of waveguide simultaneously.The invention has the advantages that: at first this version can realize the wide good electric property of all-wave conduction band, compares less than 1.1 (27dB) at the wide standing internal wave of all-wave conduction band; Next adopts frame mode of the present invention, component compact, and compact in size for example can be accomplished 15mm in the X-band device length, in the Ka frequency range, transducer length can be accomplished 6mm; The 3rd, structure processing is simple, and experiment is installed, debugging is convenient, and the round platform of coaxial inner conductor and its end can carry out integrated design processing, and it is suspended in the waveguide, does not need and mate the electrical connection closely between step; The 4th, but metal matched column 6 Design and Machining become adjustable form, it stretches into the inner height of waveguide and can in experimental debugging, finely tune, and the adverse effect that compensation brings because of mismachining tolerance is so that reach optimal electric property.
The present invention has realized that waveguide coaxial converter satisfies the premium properties of miniaturization, broadband, little standing wave simultaneously, and its structure processing manufacturability is good, and experimental debugging is convenient.For example can be reduced to 15 millimeters by 50 millimeters of conventional step in the wide transducer length of X frequency range all-wave conduction band, in the Ka frequency range, transducer length can be reduced to 6 millimeters by 20 millimeters.
