Abstract

Dispositivo per migliorare l'efficienza di un sistema radiativo per mezzo di elementi parassiti ricavati sul piano di massa, costituito da dipoli a mezza lunghezza d'onda (1) e quattro fessure non direttamente alimentate (2) essendo queste ultime eccitate da detti elementi attivi collegati ad una rete di alimentazione (4). Scopo principale è controllare il diagramma di irradiazione di un array di dipoli per mezzo di dette fessure (2). L'invenzione si colloca nel campo tecnico delle antenne, più in particolare in quello delle antenne a microonde e può essere utilizzato, in campo applicativo, sulle antenne a riflettore per il controllo del traffico aereo, dove è richiesto un avvistamento in banda S, unitamente ad una funzione di interrogazione ottenuta inserendo il dispositivo innovativo in un eventuale preesistente illuminatore in grado di esercitare un controllo sul diagramma di radiazione di tutto il sistema radiante o antenna, a seconda dello scopo cui essa è destinata.Device for improving the efficiency of a radiative system by means of parasitic elements obtained on the ground plane, consisting of half-wavelength dipoles (1) and four slots not directly fed (2), the latter being excited by said active elements connected to a power supply (4). The main purpose is to control the irradiation diagram of an array of dipoles by means of said slots (2). The invention is placed in the technical field of antennas, more particularly in that of microwave antennas and can be used, in the application field, on reflector antennas for air traffic control, where an S-band sighting is required, together to an interrogation function obtained by inserting the innovative device in a possible pre-existing illuminator capable of exercising control over the radiation diagram of the entire radiant system or antenna, depending on the purpose for which it is intended.
