Razvoj parabolnih anten za usmerjene radijske zveze : končno poročilo o izvajanju in realizaciji raziskovalno razvojnih del na projektu 72-6065-92Vilhar, Robert, 1964-S širitvijo mobilnih in osebnih komunikacij ter splošnim razmahom vseh ostalih vrst telekomunikacij se veča potreba po usmerjenih mikrovalovnih zvezah visoke kapacitete prenosa. Poleg prenosa po ... optičnih kablih, je prenos po mikrovalovnih zvezah edini učinkovit način za izgradnjo hrbtenice komunikacijskega omrežja. Sestavni del vsake naprave za radijski prenos je tudi ustrezna antena. Najbolj primerne so patabolne antene, ker omogočajo visoko stopnjo usmerjenosti in velik dobitek. Zato smo za lastnr potrebe razvili in izdelali parabolne antene različnih premerov (0,8 m, 1,2 m, in 1,8 m) za različna frekvenčna področja (od 1,5 GHz do 18,0 GHz). Vse antene imajo možnost pritrditve zaščitnega pokrova, ki anteno ščiti pred zunanjimi vremenskimi vplivi in zmanjša mehanske obremenitve zaradi vetra. Posebno pozornost smo posvetili razvoju in izdelavi primarnih virov. Poudarek smo dali skalarnim lijakom in dvopolarizacijskemu viru za frekvenčno področje 17,7-19,7 GHz. S pridobljenim znanjem smo razvili ustrezna orodja in tehnologijo, ki je potrebna za izdelavo parabolne antene poljubne velikosti za poljubno mikrovalovno frekvenčno področje.Type of material - bookPublication and manufacture - Ljubljana : Iskra Elektrozveze Transmission, 1994Language - slovenianCOBISS.SI-ID - 44630
