Hiki i ka antenna horn dual-polarized ke hoʻouna a loaʻa i nā nalu electromagnetic horizontally polarized a me ka vertically polarized i ka wā e mālama ana i ke kūlana kūlana ʻaʻole i hoʻololi ʻia, i hiki ke hoʻololi ʻia ka hewa o ka ʻōnaehana kūlana ma muli o ka hoʻololi ʻana i ke kūlana antenna i mea e hoʻokō ai i nā koi o ka hoʻololi polarization. Loaʻa i ka antenna ʻelua-polarized horn ka pōmaikaʻi o ka loaʻa kiʻekiʻe, alakaʻi maikaʻi, hoʻokaʻawale polarization kiʻekiʻe, mana mana kiʻekiʻe, a me nā mea ʻē aʻe, a ua aʻo nui ʻia a hoʻohana ʻia. Hiki i ka antenna pālua-polarized ke kākoʻo i ka polarization linear, polarization elliptical a me nā nalu polarization circular.
ʻAno hana:
| ʻAno Loaʻa |
| • Ke loaa ka antenna i ka linearly polarized vertical waveform, hiki wale i ke awa kupapau ke loaa, a ua kaawale ke awa. • Ke loa'a ka antenna i ka nalu polarization elliptical a poepoe paha, e loa'a i na awa ku a me na awa ke ku a me ka pae o ka hoailona. Ma muli o ka polarization circular polarization (LHCP) a i ʻole ka polarization pōʻai ʻākau (RHCP) o ka nalu, aia kahi pae 90-degree e lohi ana a holomua paha ma waena o nā awa. Inā hoʻopololei maikaʻi ʻia ke ʻano nalu, e like nō ka amplitude hōʻailona mai ke awa. Ma ka hoʻohana ʻana i kahi hui hui hybrid kūpono (90 degere), hiki ke hoʻohui ʻia ka ʻāpana kū a me ka ʻaoʻao ākea e hoʻihoʻi i kahi ʻano nalu pōʻai a elliptical. |
| ʻAno hoʻouna |
| • Ke hānai ʻia ka antenna e kahi awa kū pololei, hoʻouna ia i ka nalu polarization line vertical. • Ke hānai ʻia ka antenna e ke awa ākea, hoʻouna ia i ka nalu polarization line horizontal. • Ke hāʻawi ʻia ka antenna i nā awa kū pololei a me nā awa e ka ʻokoʻa 90-degere, nā hōʻailona amplitude like, e hoʻouna ʻia ka nalu LHCP a i ʻole RHCP e like me ka pae lohi a holomua paha ma waena o nā hōʻailona ʻelua. Inā ʻaʻole like nā amplitudes hōʻailona o nā awa ʻelua, ua hoʻouna ʻia ka elliptical polarization waveform. |
| Ke ʻano hoʻololi |
| • Ke hoʻohanaʻia ka antenna i ka hoʻouna a me ka loaʻaʻana o keʻano, ma muli o ka hoʻokaʻawaleʻana ma waena o nā awa kū pololei a me ke ākea, hiki iā ia ke hoʻouna a loaʻa i ka manawa like. |
