The transmission line comprises a concave or double-faced concave dielectric substrate with double faces covered with metal plasters, and a row of metal through holes connected with top and bottom metal plasters are respectively made at two sides of a projection of the dielectric substrate. A technical problem to be overcome in the utility model is to provide the RgSIW transmission line which not only maintains the advantages of easy processing, easy integration, high quality factors and the like of substrate integrated waveguide (abbreviated as SIW), but also reduces cut-off frequency of an SIW dominant mode under the condition of a same dimension, broadens operation bandwidth of the dominant mode and can be used for reducing the dimension of a circuit.
Description
Technical field
The utility model relates to microwave guided wave technology field, relates in particular to a kind of ridge substrate integration wave-guide transmission line that adds.
Background technology
Along with the development in wireless telecommunications and radar system field of microwave, millimeter-wave technology, the use of the integrated circuit of low-cost, high reliability is increasingly extensive.Circuit structure such as metal rectangular waveguide, microstrip line etc. that past adopts cut both ways.Metal waveguide has the advantages such as quality factor (Q) is high, loss is little, and shortcoming is that volume is large, cost is high, is unfavorable for the integrated manufacturing of circuit.Microstrip line and coplanar circuit structure convenience and integrated manufacturing, but radiation loss is large, is difficult to reach designing requirement.Substrate integration wave-guide (the Substrate Integrated Waveguide that occurs in recent years, hereinafter to be referred as SIW), advantage with microstrip structure and waveguiding structure, can be integrated in easily on the active integrated circuit substrate, thereby obtain increasing concern at the design aspect of microwave and millimeter wave device, antenna and integral subsystem.As the basis of design device, antenna, integrated system, SIW transmission structure advantage is fairly obvious, but also has some limitations simultaneously.At first SIW master die worker makes limit bandwidth an octave, and especially SIW and microstrip line, rectangular waveguide etc. mate that bandwidth of operation will further compress when being connected; Secondly, the SIW general size can half be comparable with the medium wavelength, and is larger than microstrip line construction size.
Therefore, instantly need a urgent technical problem that solves to be exactly: how can propose a kind of effective measures, to have solved the problem that prior art exists.
The utility model content
Technical problem to be solved in the utility model provides a kind of ridge substrate integration wave-guide (Ridged Substrate Integrated Waveguide that adds, be called for short RgSIW) transmission line, keep SIW and easily process, on the basis of easy of integration, quality factor advantages of higher, reduce unidimensional lower SIW master's mould cut-off frequency, expand main die worker and make bandwidth, and can be used for the reduction circuit size.
In order to solve the problems of the technologies described above, the utility model provides a kind of ridge substrate integration wave-guide transmission line that adds, comprise two-sided spill or the two-sided spill dielectric substrate that is covered with metal patch, make respectively the metal throuth hole that a row connects end face and bottom surface metal patch in the protruding both sides of spill dielectric substrate.
Further, the described ridge substrate integration wave-guide transmission line that adds comprises single face and two-sided.
To sum up, the utility model provides adds ridge substrate integration wave-guide transmission line, is keeping substrate integration wave-guide high quality factor, low-loss, easily makes, on the basis of advantage easy of integration, adding ridge by single or double and reduce transmission line master mould cut-off frequency.Concrete advantage is as follows:
1, select suitable to add the ridge height and width can reduce main mould cut-off frequency below half, and the higher mode cut-off frequency is substantially constant simultaneously, thereby expands more than transmission line working band to two octave;
2, under identical operating frequency condition, can substrate integration wave-guide transmission line width reduction is over half by adding ridge, thus greatly reduce whole circuit size;
3, add the power capacity that ridge can suitably improve transmission line.
