Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the patent of the present invention is further described.

[0015] exist figure 1 Among them, the unit cell structure 1 of a conventional CSRR resonator consists of a series of interdigitated capacitors 2 and a pair of branch inductors 3, and is short-circuited to the ground plane through vias 5; according to the interdigitated capacitors, an opening is etched in the ground plane Resonant ring 8; CSRR is a material with negative permittivity and magnetic permeability at the same time.

[0016] The microstrip resonator of this embodiment is loaded with SIW structure 4 on the two sides of conventional CSRR resonator; It is realized by punching a series of metal through holes 5 . The signal is input from the input port 6 and output from the output port 7; the through hole 5 limits the propagation of the electromagnetic field in the SIW; the SIW structure 4 based on the substrate integrated waveguide is connect...

Abstract

The invention relates to a micro-strip resonator based on substrate integration waveguide, belonging to the field of waveguide resonators. The micro-strip resonator is characterized in that a CSRR resonator is formed on a substrate, and then, SIW structures are loaded at both sides of the CSRR resonator; on the premise of not increasing circuit areas or processing complexity, the CSRR resonator adopting the SIW structures can effectively improve Q values, and the invention has the advantages of smart design, compact structure, easy integration and convenience in dense integrated circuits; and because of symmetry properties, the structure of the micro-strip resonator can be directly moved to a coplanar waveguide system from a micro-strip system.

Description

technical field [0001] The invention belongs to the field of waveguide resonators, and in particular relates to a frequency control device. Background technique [0002] When discussing inductor performance, the Q value is the most important measure. It is a dimensionless parameter used to compare the frequency of oscillation and the rate of energy loss. The higher the Q value, the closer the inductor behaves to an ideal lossless inductor. That is, it is more selective in resonant circuits. Another benefit of high Q is low loss, which means less energy is dissipated in the inductor. [0003] Complementary Split Resonant Ring (CSRR), originally proposed by Martin et al. It is realized by etching a split resonator ring (SRR) on the back substrate side of the coplanar waveguide transmission line. Since CSRR is a material with negative permittivity and magnetic permeability at the same time, we call it an artificial structure (or material) , to design a compact low-pass reso...
