Abstract

The invention discloses a broadband miniaturization large-time delay non-dispersion micro-strip delay line. The broadband miniaturization large-time delay non-dispersion micro-strip delay line comprises a plurality of period loading transmission lines, buckling structure transmission lines of a plurality of sections of loading knots and two micro-strip lines, each two adjacent period loading transmission lines are connected through a buckling structure transmission line of one section of loading knot, thereby, the plurality of period loading transmission lines are cascaded together in a buckling mode to form one buckling period loading transmission line, and two ends of the buckling period loading transmission line are connected with the two micro-strip lines respectively. By means of the broadband miniaturization large-time delay non-dispersion micro-strip delay line, defects of obvious dispersion effect, large sizes and the like in terms of traditional micro-strip delay lines can be overcome, and the integration is easy.

Description

technical field [0001] The invention belongs to the field of microwave and communication technologies, and in particular relates to a broadband miniaturized large-delay non-dispersive microstrip delay line. Background technique [0002] At present, the real-time delay line is widely used in electronic and communication systems, and is one of the key components. Microstrip circuit is the main form of miniaturized circuit. Microstrip line can be regarded as a quasi-TEM transmission line within a certain bandwidth and a certain operating frequency range, and has weak dispersion characteristics. However, when the operating frequency is high and the operating bandwidth is wide, the microstrip line The dispersion characteristics of the strip line become very strong, and at the same time, the microstrip delay line with large delay usually uses a curved line structure, which has mutual coupling between the transmission lines, and such mutual coupling enhances its dispersion characte...
