MANUFACTURING METHOD OF DIELECTRIC FEED ELEMENT FOR MIRROR ANTENNAE Russian patent published in 2010 - IPC H01Q13/00 

FIELD: radio engineering.

SUBSTANCE: easy construction is provided owing to displacements of dielectric tubes of feed element. Manufacturing method of dielectric feed element for mirror antennae with circular waveguide is characterised by the fact that to the circular waveguide there inserted is cylindrical feed element made from not less than two dielectric tubes inserted into each other with possibility of displacement relative to each other. At that, outer diametre of smaller tube is chosen so that it can be equal to inner diametre of bigger tube.

EFFECT: increasing irradiation efficiency of mirror antennae with various opening angle owing to formation of different directivity diagram.
