Description
Technical field
The present invention relates to a kind of bimodulus split-ring resonator, especially produce the adjustable bimodulus split-ring resonator of the degree of coupling by through hole.
Background technology
Miniaturization has an urgent demand to communication products to electronic devices and components, particularly to the very big components and parts of the shared like this bulk specific gravity of microwave filter, wishes to effectively reduce size keeping under the prerequisite of technical indicator.Below this background, the bimodulus device receives publicity, and the all-wave ring resonator of bimodulus is by Japan and Britain scientist invention, and its frequency response has two resonance of coupling mutually, and this resonator shortcoming is that size is still bigger.
(split-ring resonator SRR) is suggested in eighties of last century the end of the nineties split-ring resonator, has occurred a series of microwave devices based on split-ring resonator afterwards.Split-ring resonator has reduced occupation space, and has obtained good performance by the bigger coupling of the nested acquisition of inner and outer ring.Use split-ring resonator to help to reduce the bimodulus size of devices.
Summary of the invention
Technical problem: the purpose of this invention is to provide a kind of bimodulus split-ring resonator based on through hole that can be used for microwave filter, the through hole technology of use allows the split ring resonator produce bimodulus, takies thereby reduce device space.
Technical scheme: the present invention relates to a through hole technology and be used for split-ring resonator, split-ring resonator uses the through hole extended line can produce the adjustable quadrature mode of resonance of the degree of coupling in some certain location.This split-ring resonator comprises first split ring and second split ring, and first split ring is nested in second split ring; The two terminals open circuit of first split ring connects first extended line at first split ring middle part, terminal first through hole that connects of first extended line; The two terminals open circuit of second split ring connects second extended line at second split ring middle part, terminal second through hole that connects of second extended line; Two terminals of second split ring are positioned at a side of second extended line of first split ring.
The adjustable length of first extended line and second extended line, the bimodulus degree of coupling of adjustment resonator.
Beneficial effect: compared with prior art, the present invention has the following advantages:
1, the bimodulus split-ring resonator of the present invention's proposition can have very little size.The present invention connects the hole in some position of single mode split-ring resonator and produces bimodulus, and a bimodulus split-ring resonator can substitute two single mode split-ring resonators, and it is constant to take up room.Utilize small size single mode resonator to construct dual-mode resonator, can be so that microwave filter significantly reduces to take up room.The present invention can be used for filter compact to design.
2, the present invention is low to technological requirement, gets final product with common PCB technology, is easy to processing, and area occupied is little, and is with low cost, has adaptability widely.
3, the degree of coupling of two quadrature modes of resonance can be regulated by regulating through hole extended line length, and flexible design is convenient.
Description of drawings
Fig. 1 is based on the compact bimodulus split-ring resonator domain schematic diagram of through hole.
The curve that the mode frequency of Fig. 2 structure shown in Figure 1 changes with through hole extended line length.
Have among the above figure: first split ring 1, first through hole 2, first extended line 3, second split ring 4, second through hole 5, second extended line 6.
Embodiment
Bimodulus split-ring resonator based on through hole of the present invention is connected the hole and is evoked bimodulus resonance by some position of resonator.
The two terminals open circuit of first split ring 1 connects first extended line, 3, the first extended lines, 3 terminal first through holes 2 that connect at first split ring, 1 middle part; The two terminals open circuit of second split ring 4 connects second extended line, 6, the second extended lines, 6 terminal second through holes 5 that connect at second split ring, 4 middle parts; First split ring 1 and second split ring 4 are nested against one another.
The degree of coupling of bimodulus can be regulated by the length of first extended line 3 and second extended line 6.Split-ring resonator is compact resonator, and long spacing is narrow more more for the Coupled Line Length of Band between first split ring 1 and second split ring 4, and resonator is compact more.
Fig. 2 has provided the situation of two pattern resonance frequencys along with first extended line 3 and second extended line, 6 length variations.Increase along with length becomes big coupling, two curves of representing two pattern resonance frequencys respectively are overstepping the bounds of propriety among the figure opens more.Fig. 2 illustrates that the present invention has realized the adjustable of the generation of bimodulus and Mode Coupling degree.
