Ngati munayamba mwalowa mu labu yoyesera ya EMC kapena kugwira ntchito pa makina owunikira ma wideband, mwina mwakumanapo ndi vuto laantenna ya biconicalPoyamba, mawonekedwe ake ofanana, ofanana ndi uta, amaonekera bwino—zinthu ziwiri zozungulira zikuyang'anizana, zodyetsedwa pakati. Koma kupitirira mawonekedwe ake apadera pali kapangidwe kamene kamathetsa vuto lalikulu mu uinjiniya wa ma antenna: kukwaniritsa magwiridwe antchito okhazikika pamlingo waukulu kwambiri.
Momwe Zimagwirira Ntchito
Antena ya biconical ingaganizidwe ngati kupitiriza kwa chingwe cholumikizira bwino. Tangoganizani kutenga chingwe cha waya ziwiri ndikupindika pang'onopang'ono ma conductors kupita kunja mpaka atapanga ma cone—ndicho lingaliro lenileni. Kusintha pang'onopang'ono kumeneku kuchokera ku guided wave kupita ku free-space wave ndiko kumapangitsa biconical kukhala ndi mtundu wake wa broadband.
Mosiyana ndi ma antenna ozungulira omwe amagwira ntchito bwino pafupi ndi ma frequency enaake, mawonekedwe a biconical amalola kuti iwuluke bwino kudzera mu ma octaves angapo. Ngodya ya ma cones imatsimikizira kukana kwapadera, pomwe kutalika kumakhazikitsa malire a ma frequency otsika - ma cones ataliatali amatanthauza ma frequency otsika.
Ubwino Waukulu
1. Ntchito ya Ultra-Wideband: Iyi ndi mbali yodziwika bwino ya biconical. Antena imodzi imatha kuphimba ma frequency ratios a 10:1 kapena kuposerapo—kuyambira makumi a MHz mpaka ma GHz angapo. Pa makina omwe amafunika kuwunika, kuyesa, kapena kulumikizana m'magulu angapo, biconical imodzi ikhoza kusintha ma antenna angapo a narrowband.
2. Kapangidwe ka Omnidirectional mu H-Plane: Mu ndege yopingasa, biconical imatuluka mofanana mbali zonse—chinthu chofunikira kwambiri pa ntchito monga kuyesa kwa EMC komwe zizindikiro zingafike kuchokera mbali iliyonse, kapena pamakina owulutsa ndi owunikira omwe amafunikira kufalikira kwa 360°.
3. Kapangidwe Kogwirizana Pafupipafupi: Mosiyana ndi ma antenna ena a broadband omwe amasintha kwambiri mawonekedwe awo a radiation ndi pafupipafupi, ma biconical opangidwa bwino amakhala ndi mawonekedwe okhazikika—khalidwe lofunika kwambiri pamene kuyeza kubwerezabwereza kuli kofunika.
4. Kapangidwe Kosavuta, Kolimba: Palibe maukonde ovuta osinthira kapena nyumba zosalimba—koma ma cone achitsulo ndi chakudya. Izi zimapangitsa kuti ma biconical akhale odalirika m'malo ochitira labu komanso panja.
Mapulogalamu Odziwika
Kuyesa kwa EMC/EMI——Iyi mwina ndiyo njira yodziwika kwambiri. Ma Biconical ndi zida zodziwika bwino zoyezera mpweya woipa komanso chitetezo chamthupi kuyambira 30 MHz mpaka 1 GHz ndi kupitirira apo. Mtundu wawo wa broadband umalola kuti ma frequency awo azitha kufalikira mwachangu popanda kusintha ma antenna.
Kuyang'anira Masewero a Pakompyuta——Kwa mabungwe aboma ndi ogwira ntchito zamatelefoni omwe amayang'anira masewero a wailesi, masewero a biconical amapereka chithandizo chopitilira m'mabande angapo, zomwe zimapangitsa kuti ma antenna a narrowband asapezeke.
Kulankhulana kwa Broadband——M'machitidwe omwe amafunikira kufalikira mbali zonse m'magawo osiyanasiyana a ma frequency—monga ma radio ankhondo ankhondo kapena maulalo a data a ma multi-band—ma biconical amapereka yankho la antenna imodzi.
Kuyeza Mphamvu ya Munda——Pa kafukufuku wa malo ndi kutsimikizira kufalikira, mawonekedwe okhazikika a biconicals ndi mayankho a broadband zimapangitsa kuti zikhale zida zodalirika zoyezera.
Zoganizira za Kapangidwe
Ma biconical othandiza nthawi zambiri amagwiritsa ntchito ma cone a waya kapena mbale zamakona atatu m'malo mwa chitsulo cholimba kuti achepetse kulemera ndi katundu wa mphepo. Pakuyika panja, ma radomes amateteza ku nyengo. Malo odyetsera amafunika kukonzedwa mosamala kuti asunge bwino komanso kufananiza impedance - nthawi zambiri amachitidwa ndi baluns kapena coaxial feeds yokhala ndi ma conductors opangidwa mwapadera.
Antena ya biconical yapeza malo ake ngati chida chodalirika m'ma labu a EMC, malo owunikira, ndi machitidwe olumikizirana padziko lonse lapansi. Yankho lake labwino kwambiri pa vuto la kufalikira kwa wideband—pogwiritsa ntchito geometry m'malo mwa circuitry yovuta—limasonyeza chowonadi chakuya chaukadaulo: nthawi zina mawonekedwe osavuta kwambiri amagwira ntchito bwino kwambiri.
Ku RFMiso, timaphatikiza kapangidwe kameneka komwe kayesedwa nthawi yayitali ndi kupanga kolondola komanso zipangizo zamakono kuti tipereke ma antenna a biconical omwe akwaniritsa zofunikira masiku ano—kaya mu labu kapena kunja kwa munda.
