[0041] Example 1
[0042] Reference figure 1 The present invention is mainly composed of a microstrip dielectric substrate 11, two identical capacitor-loaded square resonant rings 13 and a pair of input and output "dry" type feeders 17. among them:
[0043] The lower layer of the microstrip dielectric substrate 11 is a copper-clad ground plate 12, two identical capacitor-loaded square resonant rings 13 are located on the upper layer of the microstrip dielectric substrate 11, and each capacitor-loaded square resonant ring 13 is loaded by square metal rings 14, four The metal sheet 15 and the square perturbation metal sheet 16 are formed. The perturbation metal sheet 16 is located inside the square metal ring 14. The four loading metal sheets 15 adopt an arrow-shaped structure. The two edges 151 and 152 of the arrow are perpendicular to each other. The two sides of the square metal ring 14 are parallel, and the four loading metal sheets 15 are respectively located on the four corner...

[0052] Reference Figure 5 The present invention is mainly composed of a microstrip dielectric substrate 31, two identical capacitor-loaded square resonant rings 33, and a pair of input and output coplanar waveguide feeders 37. among them:
[0053] The lower layer of the microstrip dielectric substrate 31 is a copper-clad ground plate 32. Two identical capacitor-loaded square resonant rings 33 are located on the upper layer of the microstrip dielectric substrate 31. Each capacitor-loaded square resonant ring 33 consists of square metal rings 34 and four The loading metal sheet 35 is composed of a square perturbation metal sheet 36. The perturbation metal sheet 36 is located inside the square metal ring 34. The four loading metal sheets 35 adopt an arrow-shaped structure and are located on the four corners of the square metal ring 34. These four loading metal sheets act as capacitors, which can effectively reduce the resonance frequency and reduce the size of the...
