Abstract

PURPOSE:To simplify a feed system and also to manufacture an antenna easily by arranging a radio wave lens, composed of several lenses changing an arrival spherical wave in phase center point, between a feed horn and main reflex mirror. CONSTITUTION:On the Z axis of main reflex mirror 1 composed of one part of a paraboloid which has a rotational symmetric axis on the Z axis and its focus at point F, radio wave lens 10 consisting of partial lenses 11 and 12 and feed horn 2 with its phase center point of a radiation spherical wave at point P are both arranged. Among spherical waves radiated from focus P, waves having penetrating partial lens 11 strike main reflex mirror 1 as spherical waves centering on point F11 and those penetrating lens 12 as waves centering on F12; and they are reflected by main reflex mirror 1 and advance along axes 26 and 27 inclined at constant angles (PSI11) and (PSI12) to the Z axis respectively.
