Embodiment Construction

[0014] In the dual-mode split ring resonator based on the through hole of the present invention, the dual-mode resonance is excited by connecting the hole at certain positions of the resonator.

[0015] The two terminals of the first split ring 1 are open-circuited, and the first extension line 3 is connected to the middle part of the first split ring 1, and the end of the first extension line 3 is connected to the first through hole 2; the two terminals of the second split ring 4 are open-circuited, and the second The middle part of the split ring 4 is connected to the second extension wire 6 , and the end of the second extension wire 6 is connected to the second through hole 5 ; the first split ring 1 and the second split ring 4 are nested with each other.

[0016] The dual-mode coupling degree can be adjusted by the lengths of the first extension line 3 and the second extension line 6 . The split ring resonator is a compact resonator, the longer the length of the coupling l...

Abstract

The invention relates to a resonator, in particular to a dual-mode opening ring resonator based on a through hole; dual modes with adjustable coupling degree are generated on the basis of through hole. The opening ring resonator comprises a first opening ring (1) and a second opening ring (4); the first opening ring (1) is embedded inside the second opening ring (4); two terminals of the first opening ring (1) have open circuits; the middle part of the first opening ring (1) is connected with a first extension wire (3); the end of the first extension wire (3) is connected with a first through hole (2); two terminals of the second opening ring (4) have open circuits; the middle part of the second opening ring (4) is connected with a second extension wire (6); the end of the second extension wire (6) is connected with a second through hole (5); and two terminals of the second opening ring (4) are arranged at one side of the second extension wire (6) of the first opening ring (1). The opening ring resonator of the invention has dual-mode characteristic, simple design, compact structure, convenient process and low cost.

Description

technical field [0001] The invention relates to a dual-mode split-ring resonator, in particular to a dual-mode split-ring resonator with adjustable coupling degree generated through through holes. Background technique [0002] Communication products have urgent requirements for the miniaturization of electronic components, especially for components such as microwave filters that occupy a large proportion of volume, it is hoped to effectively reduce the size while maintaining technical indicators. Under this background, dual-mode devices have attracted attention. The dual-mode full-wave ring resonator was invented by Japanese and British scientists. Its frequency response has two mutually coupled resonances. The disadvantage of this resonator is that its size is still large. [0003] The split-ring resonator (SRR) was proposed in the late 1990s, after which a series of microwave devices based on the split-ring resonator appeared. The split ring resonator achieves greater cou...
