摘要:
The waveguide device, in which first/second openings are formed at end parts of a waveguide path, comprises a waveguide path obtained by uniting first/ second waveguides. The first waveguide is provided with a first recessed part which has an opening with a same shape as the first opening and has a bottom part formed in a first direction as seen from the opening. The second waveguide is provided with a second recessed part which has an opening with a same shape as the second opening and has a bottom part formed in a second direction as seen from the opening. The first/second waveguides are united in a manner such that, positions of the bottom parts of the first/second recessed parts are different from each other in a direction differing from the first/second directions, and the first/second recessed parts connect with each other at the respective bottom parts.

A junction for connecting two waveguides (101, 103) having substantially a 90-degree angular offset between longitudinal symmetry axes of their cross-sections, said junction comprising a first interface (102) and a second interface (104) for connecting said waveguides (101, 103), and further comprising at least a first transformer section (202) and a second transformer section (206), both having cross- sections of substantially rectangular shape, and both having said 90-degree angular offset between longitudinal symmetry axes of their cross-sections, wherein the first and the second transformer sections (202 and 206) are connected in a way that a T- shape connection is formed and the first transformer section (202) has a first protruded ridge (204) on its broad wall (210) and the second transformer section (206) has a second protruded ridge (208) on its broad wall (212), wherein the broad wall (212) with the second ridge (208) is connected to the top narrow wall of the first transformer section (202) and the ridges (204 and 208) are so located that they overlap.
摘要:
A system for alignment of the polarisation of an electromagnetic wave between a first and a second guiding structure of a communication system operating with linearly polarised signals is described, in which the first guiding structure is orientable for alignment with the direction of polarisation of a signal received or transmitted by the system and the second structure is fixed with respect to a general reference system of the system. The system includes a first 90° waveguide differential phase shifter device (PS1) fixed to the first guiding structure, and a second 90° wave guide differential phase shifter device (PS2) fixed to the second guiding structure, coupled together for rotation by means of a rotary joint (RJ) in such a way as to allow rotation of the first orientable structure with respect to the second fixed structure through an angle corresponding to the original misalignment angle.

L'invention concerne un dispositif répartiteur de puissance dans un guide d'ondes (10) fonctionnant en polarisation linéaire alimenté par une onde, de longueur d'onde λg, en mode fondamental. Ce dispositif comprend en son extrémité un second guide (11) à la coupure formant un plan de court-circuit (18) avec le premier guide, et au moins deux fentes radiales (14, 15) de directions perpendiculaires, disposées à la périphérie du premier guide à une distance déterminée du plan de court-circuit (18) de manière telle que l'énergie couplée dans ces fentes soit maximum, la direction radiale de l'une de ces fentes formant un angle déterminé par rapport du plan de polarisation de l'onde incidente dans le plan moyen perpendiculaire à ces deux fentes (14, 15).
