I-eriyali yophondo oluphindwe kabini iyakwazi ukusasaza kwaye ifumane ngokuthe tye kunye namaza e-electromagnetic polarized polarized ngelixa igcina imeko ingatshintshwanga, ukuze impazamo yenkqubo yokutenxa ebangelwa kukutshintsha indawo ye-eriyali ukuze kuhlangatyezwane neemfuno zokutshintsha kwe-polarization kupheliswe, kwaye ukwenzela ukuba ukuchaneka kwenkqubo kube nokuphuculwa. I-antenna yophondo oluphindwe kabini ineenzuzo zokufumana okuphezulu, ukuqondisa okulungileyo, ukuhlukaniswa okuphezulu kwe-polarization, amandla aphezulu, njl., kwaye ifundwe ngokubanzi kwaye isetyenziswe. I-eriyali ene-polarized ezimbini inokuxhasa i-polarization yomgca, i-elliptical polarization kunye ne-circular polarization waveforms.
Imo yokusebenza:
| Indlela yokufumana |
| • Xa i-eriyali ifumana imo ethe nkqo yomgca yomgca, lizibuko elithe nkqo kuphela elinokuyifumana, kwaye izibuko elithe tye libe lodwa. kwadwa. • Xa i-eriyali ifumana i-elliptical or circular polarization waveform, amazibuko athe nkqo nathe tye afumana iinxalenye zesignali ezithe nkqo nezithe tye, ngokulandelelanayo. Ngokuxhomekeke kwi-polarization ye-circular yesandla sasekhohlo (LHCP) okanye i-polarization yesangqa sasekunene (RHCP) ye-waveform, kuya kuba nesigaba se-90-degree okanye ukuqhubela phambili phakathi kwamazibuko. Ukuba i-waveform ijikeleze ngokugqibeleleyo i-polarized, i-amplitude yesignali esuka kwizibuko iya kufana. Ngokusebenzisa i-coupler ye-hybrid efanelekileyo (i-90 degree), i-vertical component kunye ne-horizontal component inokudibaniswa ukubuyisela i-circular or elliptical waveform. |
| Imo yoThutho |
| • Xa i-eriyali ityiswa lizibuko elithe nkqo, ithumela i-antenna ye-polarization waveform. • Xa i-eriyali ityiswa lizibuko elithe tye, ithumela i-antenna exwesileyo ye-polarization waveform. • Xa i-eriyali ifakwa kumazibuko athe nkqo nathe tye ngumahluko wesigaba se-90-degree, imiqondiso yeamplitude elinganayo, i-LHCP okanye i-RHCP i-waveform ikhutshelwa ngokokuqhwalela kwesigaba okanye ukuya phambili phakathi kwemiqondiso emibini. Ukuba i-amplitudes yomqondiso wamazibuko amabini ayilingani, i-elliptical polarization waveform iyahanjiswa. |
| Imo Yokugqithisela |
| • Xa i-eriyali isetyenziswa kwindlela yokudlulisa nokufumana, ngenxa yokwahlukaniswa phakathi kwamazibuko amileyo nathe tye, inokudlulisela kwaye ifumane kwangaxeshanye. |
RF MISOinikezela ngeentambo ezimbini ze-eriyali ezimbini-polarized, enye isekelwe kwisakhiwo se-quad-ridge kwaye enye isekelwe kwi-Waveguide Ortho-Mode Transducer (WOMT). Ziboniswa kwi-Figure 1 kunye ne-Figure 2 ngokulandelanayo.

Ukufana kunye nokungafani phakathi kwee-antenna ezimbini kuboniswe kwiThebhile 1. Ngokuqhelekileyo, i-eriyali esekelwe kwisakhiwo se-quad-ridge sinokugubungela i-bandwidth ebanzi yokusebenza, ngokuqhelekileyo ngaphezu kwe-octave band, njenge-1-20GHz kunye ne-5-50GHz. Ngezakhono zoyilo ezigqwesileyo kunye neendlela ezichanekileyo zokulungisa,RF MISOI-eriyali ebanzi-ebanzi ephindwe kabini inokusebenza kwiifrikhwensi eziphezulu zamaza ezimilimitha. I-bandwidth yokusebenza yee-antenna ezisekelwe kwi-WOMT inqunyelwe yi-bandwidth yokusebenza ye-waveguide, kodwa inzuzo yayo, ububanzi be-beam, i-lobes yecala kunye ne-cross polarization / i-port-to-port isolation ingaba ngcono. Okwangoku kwimarike, uninzi lwee-eriyali ezi-polarized ezimbini ezisekelwe kwi-WOMT zine-20% kuphela ye-bandwidth yokusebenza kwaye azikwazi ukugubungela ibhendi yamaza amaza. I-eriyali ye-WOMT esekwe kabini-ipolarized eyilwe nguRF MISOinokugquma ibhendi yefrikhwensi ye-waveguide epheleleyo, okanye ngaphezulu kwebhendi ye-octave. Kukho iimodeli ezininzi onokukhetha kuzo.
