Description
Technical field
The utility model belongs to field of microwave communication, is especially applicable to satellite communication field, and it is a kind of broadband, body
The small K-band small size broadband waveguide bandpass filter of the small, insertion loss of product.
Background technology
The passive filtering device with specific frequency-selecting function that waveguide filter is made up of coupling window resonant cavity.Waveguide
Filter Q is high, and with high power work ability, insertion loss is small, the high and good passband stationary wave characteristic of Out-of-band rejection, extensively
Apply to radar, electronic countermeasure, the field such as microwave communication.
It is more next to broadband, small size, high performance waveguide filter demand with continuing to develop for modern communication technology
Bigger but common waveguide filter is big because of its volume, and narrow bandwidth is in modern communicationses field using there is certain defect.Therefore,
In the case where keeping its high electrical performance, reduce volume expansion bandwidth tool and be of great significance.Existing common waveguide filter
Ripple device, because two resonator stiffness of couplings of its structures shape not enough lead to not accomplish broadband, narrower bandwidth, typically 15%
Hereinafter, and cross section is big so that overall volume is larger.
Utility model content
The purpose of this utility model, which is that, provide a kind of K-band small size broadband waveguide band to solve the above problems
Bandpass filter.
The utility model is achieved through the following technical solutions above-mentioned purpose：
Set in a kind of K-band small size broadband waveguide bandpass filter, including resonator and coupling window, the resonator
Have and some metal columns are set side by side with a metal ridge, the metal ridge, form described between adjacent two metal columns
Coupling window.
Preferably, the metal column is the metal column of cube structure.
Preferably, the length sum of some metal columns and some coupling windows is equal to the length of the metal ridge.
The beneficial effects of the utility model are：
K-band waveguide filter in this patent, the advantages of its high q-factor of guarantee, filter with low insertion loss, good stationary wave characteristic
Premise it is small, solve that the intrinsic frequency band of K-band waveguide filter is narrow, bulky shortcoming, new waveguiding structure is simple, it is easy to
Processing, can be produced in batches, with good development prospect.
Brief description of the drawings
Fig. 1 is side cross section structure diagram of the present utility model；
Fig. 2 is inside top structural representation of the present utility model；
In figure：1- resonators, 2- metal columns, 3- coupling windows, 4- metal ridges.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, the utility model includes being provided with a metal in resonator 1 and coupling window 3, resonator 1
Formation coupling window 3 between the metal column 2 of some cube structures, adjacent two metal columns 2 is set side by side with ridge 4, metal ridge 4.
The length sum of some metal columns 2 and some coupling windows 3 is equal to the length of metal ridge 4.
The metal-loaded post 2 of resonator 1 is equivalent to capacitive load, and the width of metal column 2 is definite value W0, and length is definite value L0, is led to
Cross the Height Adjustable band connection frequency of change metal column 2；
The length S of coupling window 3 is definite value, and when metal column 2 is constant, stiffness of coupling can be increased by reducing its depth h, so as to increase
Plus filter bandwidht.
A is ridge waveguide broadside in figure, and b is the narrow side of ridge waveguide, and ridge width is W0, because of section for its transmission that ridge waveguide is reduced
Only frequency, K-band standard waveguide BJ220 broadsides are 10.68mm, and this patent broadside a is reduced to 4.5mm, broadside size reduction
57.8%；Narrow side b is 4.32mm, and this patent is reduced to 2.5mm, reduces 42.1%；
Common waveguide wave filter, which needs to be closing the distance, makes coupling reach maximization, but it is too near can not realize accurate processing,
When distance it is near to a certain extent when, further enhance coupling by capacitive load technology, it is ensured that to expand while machining accuracy
Bandwidth, and reduce resonant frequency by the capacitive load to resonator, the length of resonator 1 is further reduced, simultaneously
Shorten entire length.
This patent is reduced overall dimensions using ridge waveguide and capacitive load technology and expands bandwidth, passes through ridge waveguide and electricity
Holding the combination of loading technique makes K-band waveguide filter be made that small volume and with wide waveguide bandpass filter.Because of ridge ripple
Lead with lower cut-off frequency and relatively low impedance operator, its cross section can be substantially reduced compared with conventional waveguide is transmitted,
So as to reduce the overall volume of waveguide filter；Capacitive load technology adds the stiffness of coupling between each resonator, so that
Expand bandwidth.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
Any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model
In the range of shield.
