Abstract (en)
[origin: EP0548876A1] Active antenna of "offset" type having two reflectors (3, 4) in a periscope configuration. A radioelectric lens (5) is provided at the foci (F, F') of the two reflectors (3, 4). It is composed of a collector (6), and of a primary array (7) of much larger size than the collector. The "small" sources of the collector (6) correspond one-to-one and in a geographically identical manner with the "large" sources of the primary array (7) to which they are respectively linked by way of devices for fine adjustment of phase. <IMAGE>
