Inā ua komo ʻoe i loko o kahi keʻena hoʻāʻo EMC a hana paha ma nā ʻōnaehana nānā wideband, ʻo ia paha ua hālāwai ʻoe meantenna biconicalI ka nānā mua ʻana, kū i waho kona ʻano symmetrical, e like me ke kakaka—ʻelua mau mea conical e kū pono ana kekahi i kekahi, i hānai ʻia ma ke kikowaena. Akā ma waho aʻe o kona ʻano ʻokoʻa e waiho ana kahi hoʻolālā e hoʻoponopono ai i kekahi o nā pilikia nui i ka ʻenekinia antenna: ka hoʻokō ʻana i ka hana mau ma luna o kahi laulā alapine ākea loa.
Pehea e hana ai
Hiki ke noʻonoʻo ʻia ka antenna biconical he hoʻomau lapalapa o kahi laina hoʻoili kaulike. E noʻonoʻo e lawe i kahi laina ʻelua-uea a kulou mālie i nā alakaʻi i waho a hiki i ka hana ʻana i nā cones—ʻo ia ke kumumanaʻo. ʻO kēia hoʻololi mālie mai ka nalu alakaʻi i ka nalu ākea manuahi ka mea e hāʻawi ai i ka biconical i kona ʻano wideband.
ʻAʻole e like me nā antenna resonant e hana pono ana ma kahi kokoke i kahi alapine kikoʻī, ʻo ke ʻano o ka biconical e ʻae iā ia e hoʻolaha pono ma nā octaves he nui. ʻO ke kihi o nā cones e hoʻoholo i ka impedance hiʻohiʻona, ʻoiai ʻo ka lōʻihi e hoʻonohonoho i ka palena alapine haʻahaʻa—ʻo nā cones lōʻihi ke ʻano o nā alapine haʻahaʻa.
Nā Pōmaikaʻi Koʻikoʻi
1. Hana Ultra-Wideband：ʻO kēia ka hiʻohiʻona kū i waho o ka biconical. Hiki i kahi antenna hoʻokahi ke uhi i nā lakio alapine o 10:1 a ʻoi aku paha—mai nā ʻumi o MHz a i kekahi mau GHz. No nā ʻōnaehana e pono ai ke nānā, hoʻāʻo, a kamaʻilio paha ma waena o nā hui he nui, hiki i hoʻokahi biconical ke pani i kekahi mau antenna narrowband.
2. ʻAno Omnidirectional ma ka H-Plane：Ma ka mokulele ākea, hoʻolaha like ka biconical i nā ʻaoʻao āpau—he hiʻohiʻona koʻikoʻi no nā noi e like me ka hoʻāʻo EMC kahi e hiki mai ai nā hōʻailona mai kēlā me kēia kihi, a i ʻole no nā ʻōnaehana hoʻolaha a me ka nānā ʻana e pono ai ka uhi 360°.
3. ʻAno Kūlike ma ke Alapine (Frequency)：ʻAʻole e like me kekahi mau antenna wideband e hoʻololi nui i ko lākou ʻano radiation me ke alapine (frequency), mālama nā biconicals i hoʻolālā maikaʻi ʻia i kahi ʻano paʻa—he ʻano waiwai nui i ka wā e pono ai ke ana hou ʻana.
4. Kūkulu Maʻalahi a Paʻa: ʻAʻohe pūnaewele hoʻonohonoho paʻakikī a i ʻole nā hale palupalu—ʻo nā cone metala wale nō a me kahi hānai. ʻO kēia ka mea e hilinaʻi ai nā biconicals i nā wahi lab a me nā hoʻolaha kahua waho.
Nā Hoʻohana Maʻamau
Hoʻāʻo EMC/EMI——ʻO kēia paha ka noi maʻamau. ʻO nā Biconicals nā mea hana maʻamau no nā hoʻokuʻu radiation a me ka hoʻāʻo palekana mai 30 MHz a i 1 GHz a ma ʻō aku. ʻO ko lākou ʻano broadband e ʻae i nā sweeps alapine wikiwiki me ka ʻole o nā loli antenna.
Nānā ʻana i ka Spectrum——No nā keʻena aupuni a me nā mea lawelawe kelepona e nānā ana i ka spectrum lekiō, hāʻawi nā biconicals i ka uhi mau ʻana ma nā hui he nui, e hopu ana i nā hōʻailona e poina paha i nā antennas narrowband.
Nā Kamaʻilio Broadband——Ma nā ʻōnaehana e koi ana i ka uhi omnidirectional ma nā alapine ākea ākea—e like me nā lekiō koa tactical a i ʻole nā loulou ʻikepili multi-band—hāʻawi nā biconicals i kahi hopena antenna hoʻokahi.
Ana o ka Ikaika o ke Kahua——No nā ana ʻana o ke kahua a me ka hōʻoia ʻana o ka uhi ʻana, ʻo nā ʻano paʻa o nā biconicals a me ka pane broadband e hoʻolilo iā lākou i mau mea hana ana hilinaʻi.
Nā Manaʻo Hoʻolālā
Hoʻohana pinepine nā mea hana biconical i nā cone uea a i ʻole nā papa triangular ma kahi o ka metala paʻa e hōʻemi i ke kaumaha a me ka ukana makani. No nā hoʻonohonoho waho, pale nā radomes i ka wā. Pono ke kiko hānai i ka hoʻolālā akahele e mālama i ke kaulike a me ka hoʻohālikelike impedance - hoʻokō pinepine ʻia me nā baluns a i ʻole nā kahua coaxial me nā alakaʻi kikowaena i hoʻolālā kūikawā ʻia.
Ua loaʻa i ka antenna biconical kona wahi ma ke ʻano he mea hana hilinaʻi i nā keʻena hoʻokolohua EMC, nā kikowaena nānā, a me nā ʻōnaehana kamaʻilio ma ka honua holoʻokoʻa. ʻO kāna hoʻonā nani i ka pilikia uhi wideband—me ka hoʻohana ʻana i ke geometry ma mua o ka circuitry paʻakikī—e hōʻike ana i kahi ʻoiaʻiʻo ʻenekinia hohonu: i kekahi manawa ʻoi aku ka maikaʻi o nā kinona maʻalahi loa.
Ma RFMiso, hoʻohui mākou i kēia hoʻolālā i hoʻāʻo ʻia e ka manawa me ka hana pololei a me nā mea hou e hāʻawi i nā antenna biconical e hoʻokō ana i nā koi koi o kēia lā—inā paha ma ka lab a i waho paha ma ke kahua.
