Dual polarization antenna for airborne radar, has plane array constituted by dipoles overlapped with respect to flat dish so that dipoles do not disturb beam from dish, and source enlightening array which focuses wave emitted by source
The antenna has a flat dish (1), and a plane array parallel to the flat dish, where the flat dish is a slot antenna or printed antenna. The array is constituted by dipoles (3) having variable length, and a primary source (2) e.g. direct radiation monopulse source, enlightens the array focusing a wave emitted by the source. The dipoles are overlapped with respect to the flat dish so that the dipoles do not disturb the beam from the dish.
