Self-resonance structure based on open hole resonance loop

Abstract

The invention relates to a self-resonant structure based on a split resonance ring. The self-resonant structure comprises split ring structure 1 and adjunct circuit structure 2, wherein, the adjunct circuit structure 2 is positioned in an opening of the split ring structure 1 which can be formed by being surrounded by suspended metal strips and can also be a split rectangular ring or a circular ring formed by micro-strip structure printed on a media basic plate; the adjunct circuit structure 2, in whole, can be equivalent to the parallel connection of an inductor and a capacitor and can be realized by welded and lumped inductance and capacitance, also by a metal strip or distributed micro-strip structure printed on a media plate and still by a semi-lumped and semi-distributed circuit. The self-resonant structure based on a split resonance ring provided by the invention has narrow-band bandstop function, high-sensitivity frequency-phase responding and excellent stop-band or reflective characteristics and has the advantages of simple design structure, convenient processing and manufacture and excellent re-design and co-design capability and can be applied to the designs of filters (or a reflector required with high-sensitivity phase induction) in a planar circuit and spatial structure at the same time.

Description

technical field [0001] The invention relates to a self-resonant structural unit, in particular to a self-resonant structure based on a novel split resonant ring, which can be applied to the filter of a planar circuit or space structure and the design of a reflector with high-sensitivity phase induction. Background technique [0002] The split resonant ring is the basic structural unit for designing artificial negative magnetic permeability materials. It can be equivalent to a parallel self-resonance of a capacitance and inductance, and its resonance frequency is determined by the equivalent capacitance and inductance value of the structural unit. In the design of split resonant rings for artificial negative magnetic permeability materials, it is often required that the wider the operating frequency band, the better. For this reason, many scholars at home and abroad have successively proposed several new split resonant ring structures, increasing the volume of the ring structu...

Problems solved by technology

It's just that the common split resonant ring structure cannot realize high-performance narrow-band band-pass or band-stop filtering, nor can it design microwave devices with high-sensitivity frequency-phase response
