Nūhou - E hoʻomaopopo i nā loina hoʻolālā a me nā ʻano hana o nā antenna biconical

ʻO ka Antenna Biconical kahi antenna ākea kūikawā nona ke ʻano he ʻelua mau cone metala symmetrical i hoʻopili ʻia ma lalo a hoʻopili ʻia i ke kumu hōʻailona a i ʻole ka mea loaʻa ma o kahi pūnaewele trim. Hoʻohana nui ʻia nā antenna Biconical i ka hoʻāʻo ʻana i ka hoʻohālikelike electromagnetic (EMC), nā kamaʻilio uea ʻole a me nā ʻōnaehana radar. ʻO ke kumu hana o ka antenna biconical ka hoʻohana ʻana i nā ʻano noʻonoʻo a me ka radiation o nā nalu electromagnetic ma nā alakaʻi metala. Ke komo kahi nalu electromagnetic i kahi antenna biconical, e hōʻike ʻia i nā manawa he nui ma ka ʻili o ka cone, e hana ana i kahi hopena hoʻolaha multipath. ʻO kēia hoʻolaha multipath ke kumu o ka antenna e hana i kahi ʻano radiation like ma ke kuhikuhi radiation. ʻO ka hiʻohiʻona nui o nā antenna biconical ʻo kā lākou hana ākea. Hiki iā ia ke hana ma luna o kahi alapine nui, e uhi pinepine ana i kekahi mau haneli megahertz a i kekahi mau gigahertz. ʻO kēia ʻano e hoʻohana nui ʻia ai nā antenna biconical no ka hoʻāʻo ʻana a me ke ana ʻana o ke kamaʻilio uea ʻole ākea, a me ka hoʻāʻo ʻana o EMC o nā lako ma nā alapine like ʻole. Eia kekahi, he maʻalahi a maʻalahi hoʻi ke ʻano o ka antenna biconical e hana, hoʻokomo a hoʻohana. Eia nō naʻe, he mau palena ko nā antenna biconical. ʻO ka mea mua, haʻahaʻa iki ka loaʻa o ka antenna ma muli o kāna hana broadband. ʻO ka lua, ʻoiai ʻo ka hoʻolālā a me ka hana ʻana o nā antennas e pono e noʻonoʻo i ka laulā alapine a me nā koi ʻē aʻe, aia paha nā ʻano antenna like ʻole ma kekahi mau alapine. No laila, pono e koho i ka antenna biconical kūpono e like me nā koi kikoʻī i ka noi. Ma keʻano laulā, ʻo ka antenna biconical he antenna kūikawā me ka hana ākea a kūpono no ke kamaʻilio uea ʻole ākea, ka hoʻāʻo ʻana a me ke ana ʻana o EMC. Loaʻa iā ia nā pono o ke ʻano maʻalahi, ka hana maʻalahi a me ka hoʻohana ʻana, akā pono e uku ʻia ka nānā ʻana i ke koho ʻana o ka loaʻa a me nā ʻano alapine like ʻole.
