I-antenna ye-dual-polarized horn inokudlulisa kwaye ifumane amaza e-electromagnetic atyhidiweyo ngokuthe tye nathe nkqo ngelixa igcina imeko yendawo ingatshintshanga, ukuze impazamo yokuphambuka kwendawo yenkqubo ebangelwe kukutshintsha indawo ye-antenna ukuze kuhlangatyezwane neemfuno zokutshintsha kwe-polarization, kwaye ukuze ukuchaneka kwenkqubo kuphuculwe. I-antenna ye-dual-polarized horn ineengenelo ze-high gain, i-good directionivity, i-high polarization isolation, amandla aphezulu, njl.njl., kwaye ifundwe ngokubanzi kwaye isetyenziswa. I-antenna ye-dual-polarized inokuxhasa i-linear polarization, i-elliptical polarization kunye ne-circular polarization waveforms.
Indlela Yokusebenza:
| Imo Yokufumana |
| • Xa i-antenna ifumana i-waveform ethe nkqo e-linearly polarized, yi-port ethe nkqo kuphela enokuyifumana, kwaye i-port ethe tye iyahlukaniswa. • Xa i-antenna ifumana i-waveform ethe tye e-linearly polarized, yi-port ethe tye kuphela enokuyifumana, kwaye i-port ethe nkqo iyahlukaniswa. • Xa i-antenna ifumana i-waveform ye-elliptical okanye ye-circular polarization, ii-ports ezithe nkqo nezithe tye zifumana ii-components ezithe nkqo nezithe tye zesignali, ngokulandelelana. Ngokuxhomekeke kwi-polarization ye-circular yasekhohlo (LHCP) okanye i-circular polarization yasekunene (RHCP) ye-waveform, kuya kubakho i-90-degree phase lagging okanye progressing phase phakathi kwee-ports. Ukuba i-waveform i-circularly polarized, i-amplitude yesignali evela kwi-port iya kufana. Ngokusebenzisa i-coupler ye-hybrid efanelekileyo (90 degrees), i-component ethe nkqo kunye ne-horizontal component zinokudityaniswa ukubuyisela i-circular okanye i-elliptical waveform. |
| Imo yokudlulisa |
| • Xa i-antenna inikwa amandla yi-port ethe nkqo, idlulisela i-waveform ye-polarization yomgca othe nkqo. • Xa i-antenna inikwa amandla yi-horizontal port, idlulisela i-horizontal line polarization waveform. • Xa i-antenna inikwa amazibuko ami nkqo nathe tye ngomahluko wesigaba sama-90-degree, imiqondiso ye-amplitude elinganayo, i-LHCP okanye i-RHCP waveform idluliselwa ngokwesigaba esisemva okanye esiqhubekekayo phakathi kwemiqondiso emibini. Ukuba i-amplitude yesignali yamazibuko amabini ayilingani, i-elliptical polarization waveform iyadluliselwa. |
| Imo yokudlulisela |
| • Xa i-antenna isetyenziswa kwimo yokudlulisa nokwamkela, ngenxa yokuhlukaniswa phakathi kwee-ports ezithe nkqo nezithe tye, inokudlulisa kwaye ifumane ngaxeshanye. |
I-RF MISOInika uthotho lwee-antenna ezimbini ezi-polarized ezimbini, enye isekelwe kwisakhiwo se-quad-ridge kwaye enye isekelwe kwi-Waveguide Ortho-Mode Transducer (WOMT). Ziboniswe kuMfanekiso 1 kunye noMfanekiso 2 ngokwahlukeneyo.

Ukufana kunye nomahluko phakathi kwee-antenna ezimbini kuboniswe kwiTheyibhile 1. Ngokubanzi, i-antenna esekelwe kwisakhiwo se-quad-ridge inokugubungela i-bandwidth ebanzi yokusebenza, idla ngokuba ngaphezulu kune-octave band, njenge-1-20GHz kunye ne-5-50GHz. Ngezakhono zoyilo ezibalaseleyo kunye neendlela zokucubungula ngokuchanekileyo,I-RF MISOI-antenna ye-ultra-wideband dual-polarized inokusebenza kwiifrikhwensi eziphezulu zamaza e-millimeter. I-bandwidth yokusebenza yee-antenna ezisekwe kwi-WOMT inqunyelwe yi-bandwidth yokusebenza ye-waveguide, kodwa i-gain yayo, ububanzi be-beam, i-side lobes kunye ne-cross polarization/port-to-port isolation inokuba ngcono. Okwangoku kwimarike, uninzi lwee-antenna ezisekwe kwi-WOMT zine-20% kuphela ye-bandwidth yokusebenza kwaye azinakugubungela i-standard waveguide frequency band. I-antenna esekwe kwi-WOMT dual-polarized eyilwe yiI-RF MISOingagubungela ibhendi yefrikhwensi ye-waveguide epheleleyo, okanye ngaphezulu kwebhendi ye-octave. Kukho iimodeli ezininzi onokukhetha kuzo.
