The filter plane in microfita Russian doll with two ring resonators with geometry.

摘要

The present invention, combines the functions of implementing a filter in microfita planar geometry Russian doll with two ring resonators.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 two ring resonators, outer ring with the inner ring with 28 mm and 20 mm.It is composed of radiating 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 and _ r = 4,4 '(3).A planar filter geometry Russian doll with two rings resonators with 28 mm, outer ring and the inner ring with 12mm.Composed of the radiating 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 and _ r = 4.4 (3a).And a filter with planar geometry Russian doll with two ring resonators, outer ring with the inner ring with 28 mm and 8 mm.Composed of the radiating element printed on a dielectric substrate of glass fiber (18), fed by a transmission line of microfita with 50 (28), height of H = 1,5 mm and dielectric constant and _ r = 4.4 (38).
