Ii-antenna enezimpondo ezimbiliingadlulisela futhi yamukele amaza kagesi avundlile futhi aqondile ngenkathi igcina isimo singashintshiwe, ukuze iphutha lokuchezuka kwesikhundla sohlelo elibangelwa ukushintsha indawo ye-antenna ukuze kuhlangatshezwane nezidingo zokushintshwa kwe-polarization liqedwe, kuthuthukiswe ukunemba kwesistimu. Ama-antenna ophondo olunezingqimba ezimbili anezinzuzo zokuzuza okuphezulu, ukuqondisa okuhle, ukuhlukaniswa okuphezulu kwe-polarization, namandla amakhulu, futhi ziye zafundwa kabanzi futhi zasetshenziswa. Ama-antenna ane-polarized angakwazi ukusekela umugqa, i-elliptical, kanye ne-circular polarized waveforms.
Imodi yokusebenza eyinhloko:
Thola Imodi
• Uma uthi luthola i-waveform eqondile eqondile, imbobo eqondile kuphela engayithola, futhi imbobo evundlile iyahlukaniswa.
• Uma uthi luthola i-waveform evundlile ene-polarized, imbobo evundlile kuphela engayithola, futhi imbobo eqondile iyahlukaniswa.
• Uma uthi luthola amagagasi amise okweqanda noma ayisiyingi, izimbobo eziqondile nezivundlile zithola izingxenye eziqondile nezivundlile zesignali eyisiyingi eyi-polarized, ngokulandelanayo. Kuye nge-circular polarization yesandla sobunxele (LHCP) noma i-circular polarization yesandla sokudla (RHCP) ye-waveform, kuzoba nokuleleka kwesigaba esingu-90 degree noma ukuhola phakathi kwezimbobo. Uma i-waveform ihlukaniswe kahle ngokuyindilinga, i-amplitude yesiginali evela ezimbobeni izofana. Ngokusebenzisa ibhuloho elifanele (amadigri angu-90), izingxenye eziqondile nezivundlile zingahlanganiswa ukuze kubuyiselwe i-waveform eyindilinga noma eyi-elliptical.
Yethula Imodi
• Uma uthi luphakelwa kusuka endaweni eqondile, i-waveform ye-wave ehlukanisiwe eqondile idluliswa.
• Idlulisa amagagasi avundlile avundlile lapho uthi luphakelwa ngembobo evundlile.
• Uma uthi lwe-antenna luphakelwa umehluko wesigaba esingama-degree angu-90, amasignali e-amplitude alinganayo ezimbobeni eziqondile nezivundlile, ama-waveform e-LHCP noma e-RHCP adluliswa kuye ngokuthi isigaba sibambezelekile noma ukuhola phakathi kwamasignali amabili. Uma ama-amplitude esignali ezimbobeni ezimbili engalingani, i-elliptically polarized waveform idluliselwa.
Imodi ye-Transceiver
• Uma uthi lwenziwe kumodi yokudlulisa nokwamukela, ngenxa yokuhlukaniswa phakathi kwezimbobo eziqondile nezivundlile, ukudluliswa nokwamukela kanyekanye kungenzeka, njengokudluliswa okuqondile nokwamukela okuvundlile ezinhlelweni zokuxhumana.
