Ka mōʻaukala a me ka hana o nā antenna pepeiaohao cone

ʻO ka mōʻaukala o nā antenna pepeiaohao tapered e hoʻi ana i ka hoʻomaka ʻana o ke kenekulia 20. Ua hoʻohana ʻia nā antenna pepeiaohao tapered mua loa i nā amplifiers a me nā ʻōnaehana speaker e hoʻomaikaʻi i ka radiation o nā hōʻailona leo. Me ka hoʻomohala ʻana o nā kamaʻilio uea ʻole, hoʻohana mālie ʻia nā antenna pepeiaohao conical i nā kahua lekiō a me ka microwave. ʻO kona mau pono i ka radiation nalu electromagnetic a me ka hoʻokipa ʻana e lilo ia i ʻano antenna koʻikoʻi. Ma hope o nā makahiki 1950, me ka hoʻomohala wikiwiki ʻana o ka ʻenehana kamaʻilio microwave, ua hoʻomaka ka hoʻohana nui ʻia ʻana o nā antenna pepeiaohao conical i nā kahua koa a me nā kahua kīwila. Hoʻohana ʻia ia i nā noi e like me nā ʻōnaehana radar, nā ʻōnaehana kamaʻilio, nā kamaʻilio ukali, nā ana lekiō a me nā ʻāpana antenna. Ua loaʻa pū kekahi i ka hoʻolālā a me ka hoʻomaikaʻi ʻana o nā antenna pepeiaohao tapered kahi moʻo o ka noiʻi a me nā hoʻomaikaʻi. Mai ka loiloi kumumanaʻo mua a hiki i ka hoʻolauna ʻana o nā simulations helu a me nā algorithms optimization, ke hoʻomau nei ka hoʻomaikaʻi ʻana o ka hana o nā antenna pepeiaohao tapered. I kēia lā, ua lilo ka antenna pepeiaohao tapered i mea maʻamau a me ke ʻano antenna kumu i hoʻohana nui ʻia i nā kamaʻilio uea ʻole a me ka ʻenehana microwave.
Hana ia ma ke kuhikuhi ʻana i nā nalu electromagnetic mai nā awa liʻiliʻi a i nā awa nui e hoʻokō i ka loaʻa kiʻekiʻe a me ka pane alapine ākea. Ke komo kahi nalu electromagnetic i loko o ke awa liʻiliʻi o kahi antenna pepeiaohao tapered mai kahi laina hoʻoili (e like me ke kaula coaxial), hoʻomaka ka nalu electromagnetic e pālahalaha ma ka ʻili o ke ʻano tapered. Ke hoʻonui mālie nei ke ʻano conical, pālahalaha mālie nā nalu electromagnetic, e hana ana i kahi ʻāpana radiation nui aʻe. ʻO kēia hoʻonui ʻana o ke geometry ke kumu o nā nalu electromagnetic e hoʻolaha i waho o ke awa nui o ka antenna pepeiaohao tapered. Ma muli o ke ʻano kūikawā o ke ʻano cone, ʻo ka divergence beam o nā nalu electromagnetic ma kahi radiation he liʻiliʻi, no laila e hāʻawi ana i ka loaʻa kiʻekiʻe. ʻO ke kumu hana o ka antenna pepeiaohao conical e hilinaʻi nei i ka refraction, refraction a me ka diffraction o nā nalu electromagnetic i loko o ke ʻano conical. ʻAe kēia mau kaʻina hana i nā nalu electromagnetic e kālele ʻia a hoʻolaha ʻia, e ʻae ana iā lākou e hoʻolaha pono. I ka pōkole, ʻo ke kumu hana o kahi antenna pepeiaohao conical ke alakaʻi i nā nalu electromagnetic mai kahi awa liʻiliʻi a i kahi awa nui aʻe, e hoʻokō ana i ka radiation nalu electromagnetic a me ka loaʻa kiʻekiʻe ma o kahi ʻano geometric kūikawā. ʻO kēia ka mea e hoʻolilo ai i nā antenna pepeiaohao tapered i ʻano antenna koʻikoʻi i nā kamaʻilio uea ʻole a me nā noi microwave.
