I-antenna enezimpondo ezikabili ingadlulisela futhi yamukele amaza kagesi avundlile futhi aqondile ngenkathi igcina isimo singashintshiwe, ukuze iphutha lokuphambuka kwesikhundla sohlelo elibangelwe ukushintsha indawo ye-antenna ukuze kuhlangatshezwane nezidingo zokushintshwa kwe-polarization liqedwe, futhi ukuze ukunemba kwesistimu kuthuthukiswe. I-antenna ye-dual-polarized horn inezinzuzo zokuzuza okuphezulu, ukuqondisa okuhle, ukuhlukaniswa okuphezulu kwe-polarization, umthamo wamandla aphezulu, njll., futhi iye yafundwa kabanzi futhi yasetshenziswa. I-antenna ene-polarized dual-polarized ingasekela i-linear polarization, i-elliptical polarization kanye ne-circular polarization waveforms.
Imodi yokusebenza:
| Imodi yokwamukela |
| • Uma uthi lwe-antenna luthola i-waveform eqondile evundlile eqondile, imbobo eqondile kuphela engayithola, futhi imbobo evundlile ihlukaniswa yodwa.• Uma uthi luthola i-waveform evundlile evundlile, imbobo evundlile kuphela engakwazi ukuyithola, futhi imbobo eqondile iyatholakala. eyedwa. • Uma uthi luthola i-elliptical or circular polarization waveform, izimbobo eziqondile nezivundlile zithola izingxenye zesignali eziqondile nezivundlile, ngokulandelana. Kuye nge-polarization eyindilinga engakwesokunxele (LHCP) noma i-circular polarization yesandla sokudla (RHCP) ye-waveform, kuzoba nokubambezeleka kwesigaba esingu-90-degree noma ukuqhubeka phakathi kwezimbobo. Uma i-waveform ihlukaniswe kahle ngokuyindilinga, i-amplitude yesiginali esuka echwebeni izofana. Ngokusebenzisa i-coupler efanele ye-hybrid (90 degree), ingxenye eqondile kanye nengxenye evundlile ingahlanganiswa ukuze kubuyiselwe i-waveform eyindilinga noma eyi-elliptical. |
| Imodi yokudlulisa |
| • Uma uthi luphakelwa imbobo eqondile, ludlulisa i-waveform ye-polarization yomugqa oqondile. • Uma uthingo luphakelwa imbobo evundlile, ludlulisa i-waveform yomugqa ovundlile we-polarization. • Uma uthingo luphakelwa ezimbobeni eziqondile nezivundlile ngomehluko wesigaba esingama-degree angu-90, amasignali e-amplitude alinganayo, i-LHCP noma i-RHCP i-waveform idluliselwa ngokuya ngokubeleka kwesigaba noma ukuya phambili phakathi kwamasignali amabili. Uma ama-amplitudes esignali ezimbobo ezimbili engalingani, i-elliptical polarization waveform iyadluliselwa. |
| Imodi yokudlulisa |
| • Uma uthilo lusetshenziswa kumodi yokudlulisa nokwamukela, ngenxa yokuhluka phakathi kwezimbobo eziqondile nezivundlile, ingadlulisela futhi yamukele ngesikhathi esifanayo. |
RF MISOinikeza uchungechunge olubili lwama-antenna ane-polarized dual-polarized, eyodwa esekelwe esakhiweni se-quad-ridge kanti enye esekelwe ku-Waveguide Ortho-Mode Transducer (WOMT). Zikhonjiswe kuMfanekiso 1 nakuMfanekiso 2 ngokulandelana.
Umfanekiso 1 I-Dual-polarized quad-ridgedphondo antenna
Umfanekiso 2 I-Dual-polarized antenna esekelwe ku-WOMT
Ukufana nomehluko phakathi kwezinti ezimbili kukhonjiswe kuThebula 1. Ngokuvamile, uthi olusekelwe esakhiweni se-quad-ridge lungamboza umkhawulokudonsa obanzi wokusebenza, ngokuvamile ongaphezu kwebhendi ye-octave, efana ne-1-20GHz kanye ne-5-50GHz. Ngamakhono amahle kakhulu wokuklama nezindlela zokucubungula ezinembayo,RF MISOI-ultra-wideband dual-polarized antenna ingasebenza kumafrikhwensi aphezulu amagagasi amamilimitha. Umkhawulokudonsa osebenzayo wama-antenna asekelwe ku-WOMT unqunyelwe umkhawulokudonsa osebenzayo we-waveguide, kodwa ukuzuza kwayo, ububanzi be-beam, ama-side lobes kanye nokuhlukaniswa kwe-polarization/port-to-port kungaba ngcono. Njengamanje emakethe, izinti eziningi ezine-polarized dual-polarized based on WOMT zinama-20% kuphela omkhawulokudonsa osebenzayo futhi azikwazi ukumboza ibhendi yefrikhwensi ye-waveguide. I-WOMT-based dual-polarized antenna eklanywe nguRF MISOingamboza ibhendi yefrikhwensi ye-waveguide egcwele, noma ngaphezulu kwebhendi ye-octave. Kunamamodeli amaningi ongakhetha kuwo.
