Abstract

Meccanismo per regolare la frequenza di risonanza di un risonatore dielettrico avente modo di funzionamento TE 018 in presenza di un campo elettromagnetico, comprendente: un foro ricavato lungo l'asse del risonatore dielettrico; una barra di sintonia, fabbricata con materiale dielettrico a bassa perdita, sulla superficie periferica della quale è ricavato un filetto maschio; ed un filetto femmina, per impegnare il filetto maschio, ricavato nella parete del foro. La barra di sintonia viene spostata alternativamente nel foro che impegna in modo da regolare la frequenza di risonanza.
