The filter plane in microfita geometry Russian doll with three rings ressonadores

摘要

The present invention, combines the functions of implementing a filter in microfita planar geometry ressonadores Russian doll with three rings.With the intention to incorporate features of ease of implementation, the simplicity of the geometry, miniaturization, low cost of manufacture.And with consistent results and significant to be adapted to the real applications.The said filter with planar geometry Russian doll with three rings ressonadores, outer ring with 36mm and internal rings with 28 mm and 20 mm.It is composed of the element printed on a dielectric substrate of glass fibre (1), fed by a transmission line of microfita with 50 (2), height of H = 1,5 mm and dielectric constant R = 4,4 '(3).And a filter with planar geometry Russian doll with three rings ressonadores, outer ring with internal rings with 28 mm and 20 mm and 12 mm,Composed of the element printed on a dielectric substrate of glass fibre (1a), fed by a transmission line of microfita with 50 (2a), the height of H = 1,5 mm and dielectric constant R = 4.4 (3a).
