ʻO kaantenna pepeiaohao polarized pāluahiki ke hoʻouna a loaʻa i nā nalu electromagnetic polarized horizontal a me vertical polarized me ka mālama ʻana i ke kūlana kūlana i hoʻololi ʻole ʻia, i mea e hoʻopau ʻia ai ka hewa ʻokoʻa kūlana ʻōnaehana i hoʻokumu ʻia e ka hoʻololi ʻana i ke kūlana antenna i mea e hoʻokō ai i nā koi o ka hoʻololi polarization, e hoʻomaikaʻi ana i ka pololei o ka ʻōnaehana. Loaʻa i nā antenna pepeiaohao dual-polarized nā pono o ka loaʻa kiʻekiʻe, ka directivity maikaʻi, ka hoʻokaʻawale polarization kiʻekiʻe, a me ka mana nui, a ua aʻo nui ʻia a hoʻohana ʻia. Hiki i nā antenna polarized dual ke kākoʻo i nā ʻano nalu polarized linear, elliptical, a me circular.
ʻAno Hana Nui:
ʻAno Loaʻa
• Ke loaʻa i ka antenna kahi nalu kū pololei i hoʻopili ʻia me ka linear, ʻo ka puka kū wale nō ke loaʻa iā ia, a ua hoʻokaʻawale ʻia ka puka ākea.
• Ke loaʻa i ka antenna kahi nalu pālahalaha polarized linearly, hiki i ka puka pālahalaha ke loaʻa iā ia, a ua hoʻokaʻawale ʻia ke puka kū pololei.
• Ke loaʻa i ka antenna nā ʻano nalu elliptical a i ʻole circularly polarized, loaʻa i nā awa kū pololei a me ka pae nā ʻāpana kū pololei a me ka pae o ka hōʻailona circularly polarized, kēlā me kēia. Ma muli o ka polarization circular hema (LHCP) a i ʻole ka polarization circular ʻākau (RHCP) o ke ʻano nalu, e loaʻa kahi lag phase 90 degere a i ʻole ke alakaʻi ma waena o nā awa. Inā he circularly polarized kūpono ke ʻano nalu, e like ka amplitude hōʻailona mai nā awa. Ma ka hoʻohana ʻana i kahi alahaka kūpono (90 degere), hiki ke hoʻohui ʻia nā ʻāpana kū pololei a me ka pae e hoʻihoʻi i kahi nalu circular a elliptical paha.
ʻAno Hoʻokuʻu
• Ke hānai ʻia ka antenna mai kahi awa kū pololei, hoʻouna ʻia kahi ʻano nalu polarized linearly vertically.
• Hoʻouna i nā ʻano nalu polarized linearly horizontal ke hānai ʻia ka antenna mai ka puka horizontal.
• Ke hānai ʻia ka antenna e ka ʻokoʻa pae 90 degere, hoʻouna ʻia nā hōʻailona amplitude like i nā awa kū pololei a me ka pae, nā ʻano nalu LHCP a i ʻole RHCP ma muli o ka lag pae a i ʻole ke alakaʻi ma waena o nā hōʻailona ʻelua. Inā ʻaʻole like nā amplitudes hōʻailona ma nā awa ʻelua, hoʻouna ʻia kahi ʻano nalu elliptically polarized.
ʻAno Hoʻoili
• Ke hoʻohana ʻia ka antenna ma ke ʻano hoʻouna a loaʻa, ma muli o ka hoʻokaʻawale ʻana ma waena o nā awa kū a me nā awa pae, hiki ke hoʻouna a me ka hoʻokipa ʻana i ka manawa like, e like me ka hoʻouna kū a me ka hoʻokipa pae i nā ʻōnaehana kamaʻilio.
