Title:
二重の円偏波を備えた周波数分離導波管モジュール
Document Type and Number:
Japanese Patent JP2005510903
Kind Code:
A
Abstract:
The module comprises an input/output access point at a first end of a waveguide with a square cross section, called a square waveguide, two access points made of waveguides with a rectangular cross section, called rectangular waveguides, placed side by side at a second end of the square waveguide and a septum positioned in the square waveguide at the end of a separation region common to the two rectangular waveguides in order to allow the production of two circular polarizations of opposite handedness each associated with a rectangular waveguide. The module is arranged so as to form a diplexer in which the septum is included and where the access points by rectangular waveguide are extended by filters, each access point being endowed with a filter provided in order to transmit a frequency band which is different. The steps of the septum are dimensioned so as to compensate for reflections.
