Perciò, al fine di aumentare la robustezza al fuoco dei sistemi d'antenna rispetto agli apparati tradizionali, può essere considerato un design integrato del sistema radiante e di un opportuno radome ignifugo, privilegiando soluzioni che necessitano del minimo numero possibile di componenti (robustezza) e completamente rivestiti (annegati o racchiusi in un involucro) di un dielettrico ingnifugo, cattivo conduttore del calore e che non sviluppi gas tossici in caso di incendio. date: 2006 date_type: published institution: University of Trento department: ELEDIA Research Center@DISI thesis_type: masters referencetext: [1] P.
