There has never been such an all-encompassing reflector handbook in print, and no currently available title offers coverage of such recent research developments. The Handbook consists of three volumes. Volume II focuses on feed sources. Reflector antennas are extraordinary devices that combine high gain with geometrical simplicity, and can operate in broad frequency bands. Their performance, however, depends on the electrical 606 $aAntennas, Reflector$xDesign and construction 606 $aAntennas, Reflector 615 0$aAntennas, Reflector$xDesign and construction. 615 0$aAntennas, Reflector. 676 $a621.38254 702 $aSudhakar Rao$b B. 702 $aShafai$b Lotfollah 702 $aSharma$b Satish 702 $aKane$b Vicki 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910786602603321 996 $aHandbook of reflector antennas and feed systems$91074534 997 $aUNINA LEADER 01960nam2 22003973i 450 001 PUVE008747 005 20251003044318.0 012 $aneni 2827 *.** **** (3) 1551 (R)$2fei$9Caratteri greci 100 $a20230330d1551 ||||0itac50 ba 101 | $agrc$alat 102 $ait 181 1$6z01$ai $bxxxe 182 1$6z01$an 183 1$6z01$anc$2RDAcarrier 200 0 $a1 210 $eVenetiis$gapud Aldi filios$gexpensis nobilis uiri Federici de Turrisanis eorum auunculi$h1551 215 $a[20], 679, [1] p 300 $aTesto solo in greco 300 $aColophon a c. 2u7r 300 $aSegn.: *¹? a-2d? 2e? 2f-2u?. 316 $av. 1. - Legatura in pergamena semi staccata dal dorso. - Fori e scavi provocati da tarli$5IT-BN0095 , ANT FONDO RARI 14 461 1$1001PUVE008745$12001 $aˆAristotelous ‰Pasan logik?n, r?torik?n, kai poi?tik?n pragmateian periech?n tomos. 1.[-6.].
