We propose in detail Antennas for generating Nondiffracting Beams ofMicrowaves, for instance with frequencies of the order of few GHz, obtainingfair results even when having recourse to realistic apertures, with a quitereasonable diameter. The present proposal refers to sets of suitable annularslits. The possible applications are various, including remote sensing. Thepaper is in Italian. [Si propongono in dettaglio Antenne per la generazione difasci non-diffrattivi di microonde, per frequenze ad esempio dell'ordine delladecina di GHz, ottenendo discreti risultati pur ricorrendo ad antennerealistiche di diametro ridotto. La proposta e' quella di usare un set diopportuni Annular Slits. Le applicazioni possibili sono varie, includendo ilremore sensing.]
