The dielectric or ferrite also can be connected with upper and lower wall of waveguide via metal step, and the radius of the dielectric can be greater than or equal to the radius of the ferrite, and the ratio of radius of ferrite and its semi-height is 2-4. It has the advantages of wide operating frequency band and two-frequency operation.
Description
The present invention is a kind of waveguide Y junction circulator that is applicable to microwave, millimeter wave engineering, belongs to microwave, millimeter-wave technology field.
Be widely used in the waveguide Y junction circulator in microwave, the millimeter wave engineering at present, all adopt the low-order mode single mode operation.This waveguide Y junction circulator is applied to can obtain in the microwave engineering satisfied performance.Because the restriction of factors such as the Ferrite Material saturation magnetization is big inadequately, existing waveguide Y junction circulator then can not obtain satisfactory performance in the engineering of millimeter wave frequency band, mainly be work zone width (pressing 20dB calculates from degree), generally can only reach the bandwidth (list of references: electronic letters, vol of 1.5～2.0GHz in the 3mm frequency range, the 14th volume, the 2nd phase 6-16 page or leaf, in March, 1986, article name: the heavy symmetrical waveguide junction circulator of the high ferrite column H face of W frequency range part g, author: Liu Yuewu), and can only be single frequency operation.Take measures such as impedance matching abroad, can be 3GHz, but still can only in a frequency f c ± Δ f scope, realize go in ring (U.S. Hughes Electronics circulator description of product) in the bandwidth of 3mm frequency range.
The objective of the invention is at the deficiencies in the prior art, a kind of waveguide Y junction circulator in millimeter wave frequency band work is provided, it can be at f

1And f
2± Δ f
2Realize in the scope going in ring.
The present invention adopts two high-rder mode programmes of work, it is made up of waveguide Y knot, ferrite and medium, be characterized in that cylindrical ferritic two ends can be connected with the last lower wall of waveguide by medium, the radius R d of medium can be more than or equal to ferritic radius R f, ratio Rf/h=2～4 of ferritic radius R f and half height h.Conventional circulator is Rf/h＜1.5.The present invention also can be according to actual needs, be provided with the metal step in medium and the waveguide between the lower wall, this metal step can be a circular configuration, also can be triangular structure, ferrite of the present invention can be a monomer shape, also can be body structure, promptly two ferrites by symmetry constitute, be separated with dielectric layer between two ferrites, the ferrite two ends directly are connected with the last lower wall of waveguide, also can be connected with the last lower wall of waveguide by the metal step.The metal step can be the saltant structure, also can adopt the gradation type structure, and waveguide Y knot radius can increase than conventional Y knot radius, to adjust the circulator performance.
The present invention compared with prior art has broader bandwidth, can realize advantages such as two-frequency operation.Because the topped bandwidth of 3mm frequency range reaches 35GHz and (from 75GHz～110GHz), the double frequency circulator has not only enlarged topped bandwidth, and can be used as two conventional circulators uses in test macro, so improve using value and operating efficiency.Different with receive frequency in tranmitting frequency, and have in the millimeter-wave systems of certain intervals, existing circulator bandwidth can not topped two frequencies, and adopt the double frequency circulator just to meet the demands.By adjusting the structural parameters and the material parameter of circulator, can make the double frequency circulator obtain different performances, to satisfy different occasion requirements, for example, can adjust the interval of two annular frequencies, and bimodulus is partly overlapped, thus expansion circulator bandwidth of operation; The bandwidth of operation of one of them mould is enlarged, and the work broadband of another mould reduces etc.The wide 5GHz that reaches of single mode of the present invention, bimodulus overlapping bandwidth can be greater than 5GHz, and the bimodulus frequency interval is generally 6～7GHz.
