Abstract

The invention relates to amulti-branch loading dispersive delay line with miniaturized microstrip line structure. The multi-branch loading dispersive delay line includes a conductor ground plane on one side of a dielectric substrate, a main transmission microstrip line on the other side of the dielectric substrate and a multi-branch loading stub on the same side of the microstrip line. The multi-branch loading delay line comprises a conductor ground plane on one side of the dielectric substrate, a main transmission microstrip line on the other side of the dielectric substrate and a stub on thesame side of the microstrip line. The ground plane includes a number of groove lines corresponding to the loading stub, the position of the groove lines corresponding to the position of the stub. Asthat groove line on the floor isbent and the stub line is positioned on one side of the main transmission microstrip line, the miniaturization of the dispersive delay line of the invention is realize.By loading stubs of the same size, the delay time increases linearly with the number of stubs loaded. The invention has the advantages of small size, simple structure and good performance, and has good delay characteristics in a specific frequency range.

Description

technical field [0001] The invention relates to the field of delay line design, in particular to a miniaturized microstrip line structure multi-twig loaded dispersion delay line. Background technique [0002] A delay line is an element or device used to delay an electrical signal for a period of time. The delay line should have a flat amplitude-frequency characteristic and a certain phase shift characteristic (or delay frequency characteristic) in the passband, and it must have an appropriate matching impedance and a small attenuation. Group delay engineering is widely used in phased array elements, analog signal processing, and group delay equalization. Commonly used delay lines are magnetostatic wave (MSW) dispersive delay line and surface acoustic wave (SAW) dispersive delay line. [0003] Magnetostatic wave (MSW) dispersive delay lines, exploiting the intrinsic dispersive film in the ferrimagnetic quasi-static mode, can be controlled via layer, stripline, and boundary ...
