Description
Technical field
The present invention relates to a kind of microwave delay line, especially a kind of super slow wave micro-strip delay line of binary cycle.
Background technology
Delay line is a kind of common microwave passive components, is used for phased array and pulse compression system.Delay line can prolong
The time that slow signal passes through itself.Due to electromagnetic transmission speed quickly, usually require that the size of delay line is small, so as to small
Size provides time delay as long as possible.If signal just needs 300 with light velocity propagation in air, the time delay of 1 microsecond
The long delay line of rice.In order to reduce the size of delay line, it usually needs reduce signal delay line spread speed, and postpone
Line wants folding up for a section.For microwave signal delay common delay line have lumped parameter inductance capacitance delay line,
Supersonic delay line, microwave transmission line delay line and fibre delay line etc..The inductance capacitance delay line working frequency of lumped parameter
It is low.The transducer architecture of supersonic delay line is complicated, with system device is easy of integration, working frequency is not high.Fibre delay line has
Have the advantages that with wide, low, the anti-interference, good confidentiality of loss, but the structure of fibre delay line is not considerably complicated easy of integration, cost
It is higher.Common microwave transmission line delay line has microstrip line delay line, micro-strip delay line and strip line delay line etc., but at these
In delay line, the main mould of electromagnetic wave is that TEM moulds or quasi- TEM moulds, the spread speed of signal are still higher so that the ruler of delay line
It is very little or bigger, and the mutual coupling of adjacent transmission lines is stronger.When these factors make delay line fold, adjacent delay line
Distance cannot be too close.
Invention content
Technical problem:The purpose of the present invention is to propose to a kind of super slow wave micro-strip delay lines of binary cycle, which is surface
Wave transmission line structure, signal are propagated with super slow wave, and the mutual coupling of the adjacent delay line of folding is small, and size is small, convenient for integrating, are fabricated to
This is low.
Technical solution：A kind of super slow wave micro-strip delay line of binary cycle of the present invention includes medium substrate, is arranged in medium base
