Abstract

Antenna a riflettore o a lente, a scansione di fascio, configurata in modo da avere gli elementi radianti fuori dal piano focale ("imaging"), con caratteristiche migliorate in termini di guadagno e area di copertura. Detta antenna (Fig. 1) è essenzialmente costituita da un riflettore (1), da un certo numero di radiatori (3) posti fuori dal piano focale, da una rete formatrice di fascio (BNF). Si colloca nel campo tecnico delle antenne per le antenne multifascio a fascio sagomato e trova applicazione in quello dei radar, delle telecomunicazioni in generale e delle telecomunicazioni spaziali in particolare. Il vantaggio più significativo risiede nell'uso dell'antenna come antenna trasmittente, in quanto in essa viene migliorato il rapporto prestazioni elettriche/complessità.
