Lenaka la lenakalemanakana a polarized a mabelike mefuta e 'meli ea li-antenna tse sebelisoang libakeng tse fapaneng ka lebaka la litšobotsi le mesebetsi ea tsona e ikhethang. Sengoliloeng sena, re tla hlahloba litšobotsi tsa li-antenna tsa lenaka le li-antenna tse nang le polarized habeli mme re hlahlobe lits'ebetso tse fapaneng tseo li-antenna tsena li sebelisoang hangata ho tsona.
Horn antenna ke antenna e tataisang e sebelisoang haholo lits'ebetsong tsa puisano tsa microwave le radio frequency. Li tšoauoa ka sebopeho sa conical kapa pyramidal, se li lumellang ho khantša hantle le ho amohela maqhubu a motlakase. Li-antenna tsa manaka li etselitsoe ho ba le bandwidth e pharaletseng le phaello e phahameng, e leng se etsang hore li tšoanelehe bakeng sa likhokahano tsa nako e telele le lits'ebetso tsa radar.
Ka lehlakoreng le leng, antenna e nang le polarized habeli, ke lenakana le khonang ho fetisa le ho amohela maqhubu a seea-le-moea ka polarizations tse peli tsa orthogonal ka nako e le 'ngoe. Sena se bolela hore ba khona ho sebetsana le polarization e otlolohileng le e otlolohileng, ka hona ba eketsa bokhoni ba data le boleng ba matšoao lits'ebetsong tsa puisano.
E 'ngoe ea libaka tsa bohlokoa tsa ts'ebeliso ea li-antenna tsa lenaka ke lisebelisoa tsa radar. Ka lebaka la melemo ea bona e phahameng le litšobotsi tse tobileng, li-antenna tsa horn li sebelisoa hangata ho kenya radar bakeng sa taolo ea sephethephethe sa sefofane, tlhahlobo ea boemo ba leholimo le ho lebela sesole. Bokhoni ba bona ba ho fetisa le ho amohela maqhubu a motlakase ka nepo maetong a malelele bo ba etsa karolo ea bohlokoa ea theknoloji ea radar.
Ntle le lits'ebetso tsa radar, li-antenna tsa lenaka li boetse li sebelisoa puisanong ea sathelaete. Bophara ba bandwidth le phaello e phahameng ea li-antenna tsa lenaka li etsa hore li tšoanelehe bakeng sa ho fetisa le ho amohela lipontšo ho tsoa ho lisathelaete sebakeng. Ebang ke khaso ea thelevishene, khokahanyo ea inthanete kapa mekhoa ea boemo ba lefatše, li-antenna tsa lenaka li bapala karolo ea bohlokoa ho theheng likhokahano tse tšepahalang tsa puisano le lisathelaete.
Ho feta moo, li-antenna tsa horn li sebelisoa haholo mekhoeng ea puisano e se nang mohala joalo ka lihokelo tsa microwave point-to-point le li-wireless local area network (WLANs). Tsela ea bona e tobileng le phaello e phahameng li etsa hore e be tse loketseng bakeng sa ho theha likhokahano tsa mehala e telele, haholo-holo metseng ea litoropo le ea mahaeng moo likhokahano tsa marang-rang li leng bohlokoa.
RFMISOLitlhahiso tsa Series Antenna Product Series:

Ha e lemanakana a nang le polarized habeli, hangata li sebelisoa mekhoeng ea puisano e se nang thelefono e hlokang ho feta ha data le ho tšepahala ha matšoao. Ka mohlala, marang-rang a liselefouno, li-antenna tse nang le polarized tse peli li sebelisoa ho ntlafatsa bokhoni le ts'ebetso ea liteishene tsa motheo ka ho tšehetsa li-input-inputs tse ngata.(MIMO) theknoloji. Ka ho fetisa le ho amohela lipontšo ka li-polarization tse peli tsa orthogonal, li-antenna tse peli-polarized li ka fapanyetsana data ka nako e le 'ngoe, ho ntlafatsa katleho ea spectral le ho koahela marang-rang.
Ntle le moo, li-antenna tse nang le polarized tse peli ke likarolo tsa bohlokoa ho bolepi ba linaleli ba seea-le-moea le lits'ebetso tsa kutlo tse hole. Li khona ho ts'oara maqhubu a seea-le-moea a tšekaletseng le a holimo, a lumella ho lemoha le ho hlahloba ka nepo liketsahalo tsa leholimo le tsa tikoloho. Ho bolepi ba linaleli ba seea-le-moea, li-antenna tse nang le polarized tse peli li sebelisoa ho ithuta likarolo tsa polarization tsa mehloli ea bokahohle, li fana ka leseli la bohlokoa mabapi le sebopeho sa lihloliloeng tsa leholimo le bokahohle.
Lefapheng la khaso e se nang mohala, li-antenna tse nang le polarized tse peli li sebelisoa bakeng sa phetiso ea lithelevishene tsa lefatše le seea-le-moea. Ka ho sebelisa li-antenna tse nang le polarized dual-polarized, baphatlalatsi ba ka ntlafatsa ts'ebeliso ea seea-le-moea le ho ntlafatsa boleng ba matšoao a khaso, ba etsa bonnete ba hore bashebelli ba na le boiphihlelo bo betere ba pono ea molumo.
