MICROWAVE DIRECTIONAL FILTER WITH QUASI-ELLIPTIC RESPONSE

摘要

circularly polarized radiation is derived from an input waveguide (iwg) through an iris diaphragm gate (a) in an input cavity (a), where it is decomposed into orthogonal components linearly polarized (h, v). these two components are respectively along two separate paths in the direction of the outlet chamber (d).in every way, syntonisu00e9es resonances can be separately through both direct coupling and coupling activities, provide sufficient degrees of freedom to perform quasi elliptic filter.in the outlet chamber, the results of the two paths are combined to resynthu00e9tiser radiation of circular polarization, which is an iris diaphragm (g) in the direction of the exit waveguide (owg).in one embodiment, the resonant cavity to form a network trimodales four rectangular, with input and output chambers placed in opposite angles and intermediate cavities for two separate ways, placed in two ways. lation.in another variant, the six bimodal cavities form a three-dimensional network, the input and output chambers are stacked one over the other, two intermediate cell cavities for two separate paths, being adjacent to the right of entry / exit.
