Antenna pūaantenna polarized pāluaʻelua mau ʻano antenna i hoʻohana ʻia ma nā ʻano ʻano like ʻole ma muli o kā lākou mau hiʻohiʻona a me nā hana. Ma kēia ʻatikala, e ʻimi mākou i nā hiʻohiʻona o nā antenna horn a me nā antenna dual-polarized a hoʻopaʻa i nā noi like ʻole e hoʻohana mau ʻia ai kēia mau antenna.
ʻO Horn antenna kahi antenna kuhikuhi i hoʻohana nui ʻia i ka microwave a me nā ʻōnaehana kamaʻilio lekiō. Hōʻike ʻia lākou e kahi ʻano conical a pyramidal paha, e hiki ai iā lākou ke hoʻomālamalama maikaʻi a loaʻa i nā nalu electromagnetic. Hoʻolālā ʻia nā antenna Horn e loaʻa i ka bandwidth ākea a me ka loaʻa kiʻekiʻe, e kūpono iā lākou no nā kamaʻilio lōʻihi a me nā ʻōnaehana radar.
ʻO kahi antenna pālua-polarized, ma ka ʻaoʻao ʻē aʻe, he antenna hiki ke hoʻouna a loaʻa i nā nalu lekiō i ʻelua polarizations orthogonal i ka manawa like. ʻO ia ke ʻano hiki iā lākou ke mālama i ka polarization ākea a me ke kūpaʻa, a laila e hoʻonui ai i ka mana ʻikepili a me ka maikaʻi o ka hōʻailona i nā ʻōnaehana kamaʻilio.
ʻO kekahi o nā wahi noi nui no nā antenna horn he ʻōnaehana radar. Ma muli o ko lākou waiwai kiʻekiʻe a me nā hiʻohiʻona kuhikuhi, hoʻohana pinepine ʻia nā antenna horn i nā hoʻonohonoho radar no ka mālama ʻana i ka ea, ka nānā ʻana i ka wā, a me ka nānā pūʻali koa. ʻO ko lākou hiki ke hoʻouna pololei a loaʻa i nā nalu electromagnetic ma kahi lōʻihi e lilo lākou i mea nui o ka ʻenehana radar.
Ma kahi o nā ʻōnaehana radar, hoʻohana pū ʻia nā antenna horn i nā kamaʻilio satellite. ʻO ka bandwidth ākea a me ka loaʻa kiʻekiʻe o nā antenna horn e kūpono iā lākou no ka hoʻouna ʻana a loaʻa i nā hōʻailona mai nā satelite ma ka lewa. ʻO ka hoʻolaha kīwī paha, ka pilina pūnaewele a i ʻole nā pūnaewele hoʻonohonoho honua, he hana koʻikoʻi nā horn antennas i ka hoʻokumu ʻana i nā loulou kamaʻilio hilinaʻi me nā satelite.
Eia kekahi, hoʻohana nui ʻia nā antenna horn i nā ʻōnaehana kamaʻilio uea e like me nā loulou microwave point-to-point a me nā pūnaewele ʻāina ʻole (WLAN). ʻO kā lākou kuhikuhi a me ka loaʻa kiʻekiʻe e kūpono iā lākou no ka hoʻokumu ʻana i nā pilina uea lōʻihi, ʻoi aku hoʻi ma nā kūlanakauhale a me nā wahi kuaʻāina kahi mea koʻikoʻi ke kamaʻilio laina ʻike.
RFMISOHōʻike ʻia ʻo Horn Antenna Product Series:
RM-SGHA430-15（1.70-2.60GHz）
RM-BDHA618-10（6-18GHz）
RM-CDPHA3337-20 （33-37GHz）
No ka meanā antenna polarized ʻelua, hoʻohana pinepine ʻia lākou i nā ʻōnaehana kamaʻilio uila e koi ana i ka throughput data kiʻekiʻe a me ka hilinaʻi hōʻailona. No ka laʻana, i loko o nā pūnaewele kelepona, hoʻohana ʻia nā antenna dual-polarized e hoʻonui i ka hiki a me ka hana o nā kahua kahua ma ke kākoʻo ʻana i nā mea hoʻokomo lehulehu.ʻenehana (MIMO).. Ma ka hoʻouna ʻana a me ka loaʻa ʻana o nā hōʻailona i ʻelua polarizations orthogonal, hiki i nā antenna dual-polarized ke hoʻololi i ka ʻikepili i ka manawa like, hoʻomaikaʻi i ka pono spectral a me ka uhi pūnaewele.
Hoʻohui, ʻelua-polarized antennas he mea nui i ka lekiō astronomy a me nā noi mamao. Hiki iā lākou ke hopu i nā hawewe radio polarized horizontally a vertically, e ʻae ana i ka ʻike pololei a me ka nānā ʻana i nā hanana lani a me ke kaiapuni. Ma ka radio astronomy, hoʻohana ʻia nā antenna pālua-polarized e aʻo i nā waiwai polarization o nā kumu cosmic, e hāʻawi ana i nā ʻike waiwai i ke ʻano o nā kino lani a me ke ao holoʻokoʻa.
Ma ke kahua o ka hoʻolaha uila, hoʻohana ʻia nā antenna pālua-polarized no ka televise terrestrial a me ka hoʻouna ʻana i ka lekiō. Ma ka hoʻohana ʻana i nā antenna ʻelua-polarized, hiki i nā mea hoʻolaha ke hoʻonui i ka hoʻohana ʻana i ka spectrum radio a hoʻomaikaʻi i ka maikaʻi o nā hōʻailona hoʻolaha, e hōʻoia ana i kahi ʻike leo-kiʻi maikaʻi aʻe no nā mea nānā.

I ka hōʻuluʻulu ʻana, ʻo nā antennas horn a me nā antenna dual-polarized he mea maʻamau a koʻikoʻi i nā ʻano noi like ʻole me nā ʻōnaehana radar, nā kamaʻilio ukali, nā ʻupena uila, ka lekiō astronomy a me ka hoʻolaha. ʻO kā lākou mau hiʻohiʻona kūʻokoʻa a me ko lākou hiki ke hoʻolilo iā lākou i mea nui no ka hoʻokumu ʻana i nā loulou kamaʻilio hilinaʻi a kūpono hoʻi a me ka holomua ʻana i ka noiʻi ʻepekema a me ka ʻenehana ʻenehana. Ke hoʻomau nei ka noi no nā antenna hana kiʻekiʻe, ʻo ke koʻikoʻi o nā antenna horn a me nā antenna dual-polarized i nā kamaʻilio hou a me nā hana ʻepekema e manaʻo ʻia e noho koʻikoʻi.
No ka ʻike hou aku e pili ana i nā antenna, e kipa:
