Abstract

An electronically scanned antenna comprising an array (11) of elementary sources, an energy-focusing reflector (10), and feed and control electronics, with the array (11) being situated in the focal zone of the reflector, and in which elementary sources that are not used simultaneously are grouped together in classes (Ci) in which only one source can be active at a time, with all of the sources in each class (Ci) being interconnected by a passive combiner (40) for that class. The invention is applicable in particular to space telecommunications.
