专利汇可以提供Dielectric frame beam waveguide专利检索,专利查询,专利分析的服务。并且An iterative or beam waveguide consisting of several guide elements which are identical, parallel, inter-equidistant and coaxial to the beam''s axis, characterized by the fact that it is made up of several identical cross sections realized in dielectric material, with each pair of cross sections having a function equivalent to that of a resonator formed by a pair of flat parallel reflectors symmetrically placed, with each reflector having a stepped edge and with the dimensions of said cross sections having outside measurements little greater than the beam''s, the beam being in said cross sections, which are placed at equal distances from each other, the distances being equal to those separating the cross sections'' equivalent resonators'' reflectors, every cross section, which carries out a function equivalent to that of the resonators'' reflectors'' peripheral step corresponding to the cross section, creating a phase jump having a transverse area width large enough to allow reconstructing the original size of the beam modified, as it were, during passage from one cross section to the next, and having a thickness computed in a way to correspond to minimum loss or attenuation, which can be suffered by a beam-type wave.,下面是Dielectric frame beam waveguide专利的具体信息内容。

1. A beam waveguide comprising in combination a plurality of frame-like elements arranged equi-spaced and coaxially along the transmission path of the beam, each frame-like element having a frame portion comprising a dielectric material and having an overall dimension only slightly exceeding the cross-section of said beam to obtain the minimum attenuation of said beam, each of said frame portions performing a phase correction equal to a phase correction produced by a step rim in an equivalent open resonator comprising plane mirrors with a step rim along the edges and spaced apart by a distance equal to that distance between adjacent frame-like elements.
2. A beam waveguide as claimed in claim 1, wherein the frame-like elements have a rectangular shape.
3. A beam waveguide as claimed in claim 1, wherein the cross-sections of the frame-like elements progressively increase along the axis so that the beam waveguide functions as a horn type antenna.
4. A beam waveguide as claimed in claim 1, wherein the frame-like elements have a circular shape.
5. A beam waveguide as claimed in claim 2 electromagnetically coupled to another beam waveguide of the same type, each of said beam waveguides having a respective side adjacent the other whereby the electromagnetic field in one beam waveguide couples over the other beam waveguide in accordance with sizes of the adjacent sides.
