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

ʻO ka Biconical Antenna kahi antenna ākea ākea nona ka hale i ʻelua cones metala symmetrical i hoʻopili ʻia ma lalo a pili i ke kumu hōʻailona a i ʻole ka mea hoʻokipa ma o kahi pūnaewele ʻoki. Hoʻohana nui ʻia nā antenna biconical i ka hoʻāʻo electromagnetic compatibility (EMC), kamaʻilio kelepona a me nā ʻōnaehana radar. ʻO ke kumu hana o ka antenna biconical ka hoʻohana ʻana i ka noʻonoʻo a me nā hiʻohiʻona radiation o nā hawewe electromagnetic ma nā mea hoʻokele metala. Ke komo ka nalu electromagnetic i kahi antenna biconical, e ʻike ʻia ia 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 hoʻohālikelike like ʻole i ka kuhikuhi radiation. ʻO ka hiʻohiʻona nui o nā antenna biconical ʻo kā lākou hana ākea 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. Hoʻohana nui ʻia kēia hiʻohiʻona i nā antenna biconical no ka hoʻāʻo ʻana a me ke ana ʻana o ka leka uila ākea, a me ka hoʻāʻo ʻana o EMC i nā mea hana ma nā pae alapine like ʻole. Eia kekahi, maʻalahi ke ʻano o ka antenna biconical a maʻalahi e hana, hoʻokomo a hoʻohana. Eia nō naʻe, loaʻa i nā antenna biconical kekahi mau palena. ʻO ka mea mua, he haʻahaʻa loa ka loaʻa ʻana o ka antenna ma muli o kāna hana broadband. ʻO ka lua, no ka mea pono e noʻonoʻo ka hoʻolālā ʻana a me ka hana ʻana i nā antenna i ka laina alapine a me nā koi ʻē aʻe, aia paha nā ʻano antenna ʻē aʻe 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 holoʻokoʻa, ʻo ka antenna biconical kahi antenna kūikawā me ka hana ākea-band a kūpono ia no ke kamaʻilio kelepona ākea, ka hoʻāʻo ʻana a me ke ana ʻana o EMC. Loaʻa iā ia nā mea maikaʻi o ka hoʻolālā maʻalahi, hana maʻalahi a hoʻohana, akā pono e uku ʻia i ke koho ʻana o ka loaʻa a me nā ʻano like ʻole.
