Abstract
An antenna feed device () having a first waveguide () and a second waveguide () separated from the first waveguide (), each of which is assigned to feed one polarization of a dedicated antenna and each of said waveguides exhibit an overall L-shape form where at least one section of the L-shape of each waveguide is in parallel to the other, both having respectively a first () and a second () antenna end ending in one plane for connection to an ortho-mode transducer associated with the antenna, while the other sections of the two L-shape waveguides extend in opposite directions, having respectively a first () and a second () radio end, each of which ends with a single waveguide port for connection to a radio equipment and the waveguides arrangement yields an overall compact T-shape interconnection of the antenna and the radios dedicated to the orthogonal polarizations.
