Ii-antenna yophondo olunezinhlangothi ezimbiliingadlulisa futhi yamukele amagagasi kagesi ahlukaniswe ngokuvundlile naqondile ngenkathi igcina isimo sendawo singashintshi, ukuze iphutha lokuphambuka kwesimo sesistimu elibangelwa ukushintsha isikhundla se-antenna ukuze kuhlangatshezwane nezidingo zokushintsha kwe-polarization lisuswe, okuthuthukisa ukunemba kwesistimu. Ama-antenna empondo ahlukaniswe ngokuvundlile anezinzuzo zokuzuza okuphezulu, ukuqondiswa okuhle, ukuhlukaniswa kwe-polarization okuphezulu, kanye nomthamo omkhulu wamandla, futhi afundwe kabanzi futhi asetshenziswa kabanzi. Ama-antenna ahlukaniswe ngokuvundlile angasekela ama-waveform ahlukaniswe ngokuvundlile, okwe-elliptical, kanye nesiyingi.
Imodi Yokusebenza Eyinhloko:
Imodi Yokwamukela
• Uma i-antenna ithola i-waveform eqondile eqondile, i-port eqondile kuphela engayithola, futhi i-port evundlile iyahlukaniswa.
• Uma i-antenna ithola i-waveform evundlile eqondile, i-port evundlile kuphela engayithola, bese i-port evundlile ihlukaniswa.
• Lapho i-antenna ithola ama-waveforms e-elliptical noma ajikelezayo, ama-ports aqondile navundlile athola izingxenye eziqondile nezivundlile zesignali ejikelezayo ejikelezayo, ngokulandelana. Kuye ngokuthi i-circular polarization yesandla sobunxele (i-LHCP) noma i-circular polarization yesandla kwesokudla (i-RHCP) ye-waveform, kuzoba khona ukugoba noma ukuhola kwesigaba sama-degree angu-90 phakathi kwama-ports. Uma i-waveform ijikelezwe ngokuphelele, ubukhulu besignali obuvela kuma-ports buzoba bufana. Ngokusebenzisa ibhuloho elifanele (ama-degree angu-90), izingxenye eziqondile nezivundlile zingahlanganiswa ukuze kubuyiselwe i-waveform eyindilinga noma ye-elliptical.
Imodi Yokuqalisa
• Uma i-antenna inikezwa kusukela echwebeni eliqondile, i-waveform eqondile ehlukaniswe ngomugqa iyadluliselwa.
• Idlulisa ama-waveform aqondile ahlukaniswe ngomugqa lapho i-antenna inikezwa isuka echwebeni elivundlile.
• Uma i-antenna inikezwa umehluko wesigaba sama-degree angu-90, izimpawu ze-amplitude ezilinganayo kuma-port aqondile navundlile, ama-waveform e-LHCP noma e-RHCP adluliselwa kuye ngokuthi isigaba sihamba kancane noma sihamba kancane kangakanani phakathi kwezibonakaliso ezimbili. Uma ama-amplitude esignali kuma-port amabili engalingani, i-waveform e-elliptically polarized iyadluliselwa.
Imodi Yokudlulisa
• Uma i-antenna isetshenziswa kwimodi yokudlulisa nokwamukela, ngenxa yokuhlukaniswa phakathi kwamachweba aqondile navundlile, ukudluliselwa nokwamukelwa ngasikhathi sinye kungenzeka, njengokudluliselwa okuqondile nokwamukelwa okuvundlile ezinhlelweni zokuxhumana.
