ʻO ka mōʻaukala a me ka hana o nā antenna horn cone

ʻO ka mōʻaukala o nā antenna kani kani liʻiliʻi mai ka hoʻomaka ʻana o ke kenekulia 20. Ua hoʻohana ʻia nā antenna kani kani mua loa i nā amplifiers a me nā ʻōnaehana leo e hoʻomaikaʻi i ka radiation o nā hōʻailona leo. Me ka hoʻomohala ʻana o nā kamaʻilio kelepona, hoʻohana ʻia nā antenna conical horn i ka lekiō a me ka microwave. ʻO kāna mau mea maikaʻi i ka radiation hawewe electromagnetic a me ka hoʻokipa ʻana e lilo ia i mea hoʻolālā antenna koʻikoʻi. Ma hope o nā makahiki 1950, me ka hoʻomohala wikiwiki ʻana o ka ʻenehana kamaʻilio microwave, ua hoʻomaka ka hoʻohana nui ʻana i nā antenna conical horn i ka pūʻali koa a me nā kahua kīwila. Hoʻohana ʻia ia i nā noi e like me nā ʻōnaehana radar, nā ʻōnaehana kamaʻilio, nā kamaʻilio satellite, nā ana radio a me nā antenna arrays. Ua loaʻa pū i ka hoʻolālā a me ka hoʻolālā ʻana o nā antenna kani kani i ke ʻano o ka noiʻi a me ka hoʻomaikaʻi ʻana. Mai ka loiloi kumu mua a hiki i ka hoʻokomo ʻana i nā simulation helu a me nā algorithms optimization, hoʻomau ka hoʻomaikaʻi ʻana i ka hana o nā antenna kani kani tapered. I kēia lā, ua lilo ka tapered horn antenna i mea maʻamau a maʻamau i hoʻohana nui ʻia i nā kamaʻilio kelepona a me ka ʻenehana microwave.
Hana ia ma ke kuhikuhi ʻana i nā nalu electromagnetic mai nā awa liʻiliʻi a i nā awa nui aʻe e loaʻa ai ka waiwai kiʻekiʻe a me ka pane alapine ākea. Ke komo ka nalu electromagnetic i loko o ke awa liʻiliʻi o kahi antenna pū kani mai kahi laina hoʻouna (e like me ke kaula coaxial), hoʻomaka ka nalu electromagnetic e hoʻolaha ma ka ʻili o ka hale tapered. I ka hoʻonui mālie ʻana o ke ʻano conical, palahalaha mālie nā hawewe electromagnetic, e hana ana i kahi ʻāpana radiation nui. ʻO kēia hoʻonui ʻana o ka geometry e hoʻoheheʻe ʻia nā nalu electromagnetic i waho o ke awa nui o ka antenna horn tapered. Ma muli o ke ʻano kūikawā o ke ʻano cone, he liʻiliʻi ka ʻokoʻa o ka beam o nā hawewe electromagnetic i ka wahi radiation, no laila e hāʻawi ana i ka waiwai kiʻekiʻe. ʻO ke kumu hana o ka conical horn antenna e hilinaʻi nei i ka noʻonoʻo, refraction a me ka ʻokoʻa o nā hawewe electromagnetic i loko o ke ʻano conical. Hāʻawi kēia mau kaʻina hana i nā hawewe electromagnetic e nānā a hoʻopuehu, e ʻae iā lākou e hoʻomālamalama maikaʻi. I ka pōkole, ʻo ke kumu hana o kahi antenna horn conical ʻo ke alakaʻi ʻana i nā nalu electromagnetic mai kahi awa liʻiliʻi i kahi awa nui aku, e loaʻa ana i ka radiation hawewe electromagnetic a me ka loaʻa kiʻekiʻe ma o kahi ʻano geometric kūikawā. Hoʻolilo kēia i nā antenna kani tapered i ʻano antenna koʻikoʻi i nā kamaʻilio kelepona a me nā noi microwave.
