Antena ya Biconical: Mfundo Yogwirira Ntchito, Kapangidwe ndi Kugwiritsa Ntchito

A antenna ya biconicalNdi antenna ya broadband yopangidwa ndi ma cone awiri oyendetsera magetsi omwe amayikidwa pamwamba pa nsonga ndi kudyetsedwa pamwamba pake. Kusintha kwake pang'onopang'ono kumapereka bandwidth yogwira ntchito yochulukirapo kuposa dipole yachizolowezi ya waya woonda, zomwe zimapangitsa kuti ikhale yothandiza poyesa broadband, kuyesa kugwirizanitsa kwa maginito, kuyang'anira ma spectrum, kulumikizana ndi kugwiritsa ntchito radar.

Kodi Antena ya Biconical N'chiyani?

Antena ya biconical imatha kuonedwa ngati dipole ya broadband ya magawo atatu. Ma cones awiri otsutsana amagwira ntchito ngati zinthu zowala, pomwe chakudya chili pamalo opapatiza pakati pa nsonga zawo. Ngodya ya cone, kutalika kwa cone, geometry ya chakudya ndi kapangidwe kozungulira zimatsimikiza kuchuluka kwa ma frequency komwe kungagwiritsidwe ntchito, kufanana kwa impedance ndi mawonekedwe a radiation.

Kutengera kukula kwake ndi kuyika kwake, antenna imatha kupereka polarization yolunjika komanso mawonekedwe a azimuth omwe nthawi zambiri amakhala ozungulira mbali zonse. Magwiridwe a ntchito amasintha pa band yogwirira ntchito, kotero gain yomwe yatchulidwa, VSWR ndi mawonekedwe a radiation ziyenera kuyang'aniridwa nthawi zonse kuti ziwone kuchuluka kwa ma frequency omwe akufuna.

Kodi Antena ya Biconical Imagwira Ntchito Bwanji?

Mphamvu ya RF imalowa mu antenna pamalo operekera chakudya ndikuyenda m'malo operekera chithandizo omwe akukulirakulira. Chifukwa chakuti kondakitala imakula pang'onopang'ono, kusintha kuchokera ku dera loperekera chakudya kupita ku malo omasuka kumakhala kosalala pa ma frequency osiyanasiyana. Kuzindikira kumeneku kumathandiza kusunga impedance yolowera yogwiritsidwa ntchito komanso kuwala kokhazikika pa bandwidth yayikulu kuposa dipole ya narrowband.

Antena siidalira kuwunikira kwa njira zambiri mkati mwa ma cone. Kuwala kwa magetsi kumapangidwa ndi mafunde osinthasintha nthawi pamalo oyendetsera magetsi. Pa ma frequency apamwamba, kukula kwa magetsi ndi tsatanetsatane wa chakudya zimatha kupanga kusiyana kwina kwa mawonekedwe, ndichifukwa chake mapangidwe a broadband ayenera kuyesedwa pa gulu lonse logwirira ntchito.

Magawo Akuluakulu Opangira

• Mafupipafupi:Mzere wonse womwe zofunikira za impedance ndi radiation zimakwaniritsidwa.
• VSWR ndi impedance:Izi zikusonyeza momwe mphamvu ya RF imasamutsidwira bwino pakati pa chingwe cholumikizira ndi antenna.
• Phindu:Ma antenna a Broadband biconical nthawi zambiri amapereka phindu laling'ono lomwe limasiyana malinga ndi kuchuluka kwa ma antenna.
• Kachitidwe ka kuwala:Kukhazikika kwa kapangidwe ndi kufalikira kwa azimuth kuyenera kufufuzidwa pa gulu lonselo.
• Kugawanika kwa ma polarization:Kuyang'ana kwa mzere kumatsimikiza komwe kumayambira polarization yolunjika.
• Cholumikizira ndi kagwiritsidwe ntchito ka mphamvu:Zonse ziwiri ziyenera kufanana ndi makina oyesera kapena gwero la RF.
• Kukula kwa makina:Miyeso ya koni imakhudza kuchuluka kochepa kwambiri komwe kungagwiritsidwe ntchito komanso zofunikira pakuyika.

Mapulogalamu Ofala

• Kuyeza kwa EMC radiated-emission ndi chitetezo chamthupi
• Kuyesa kwa antenna ya wideband ndi RF system
• Kuwunika kwa sipekitiramu ndi kusonkhanitsa zizindikiro
• Kulankhulana opanda zingwe ndi kuyesa kwa radar
• Makina oyezera ma labotale ndi miyeso yamunda

Ubwino ndi Zofooka

Ma antenna a biconical amapereka bandwidth yayikulu, kapangidwe kosavuta komanso mawonekedwe othandiza. Angachepetse kufunikira kosintha ma antenna pamene mayeso akutenga ma frequency ambiri. Zofooka zawo zimaphatikizapo kukwera pang'ono, kukula kwa thupi pama frequency otsika komanso kusintha kwa ma radiation-pattern kumapeto kwa band.

Momwe Mungasankhire Antena ya Biconical

Yambani ndi ma frequency ofunikira, kenako yerekezerani VSWR, gain, polarization, pattern stability, connector type, power handling ndi ma mechanical dimensions. Mtunda woyesera, mounting location ndi malo ozungulira ziyeneranso kuganiziridwa chifukwa nyumba zapafupi zingakhudze muyeso wa broadband.

Onani ma RF MISOmayankho a antenna a biconical, kuphatikizapoRM-BCA812-2 ya 8-12 GHzndiRM-BCA2428-4 ya 24-28 GHz. Pa chitsanzo chogwirizana ndi kuchuluka kwa ma frequency anu ndi momwe mumayesera,Lumikizanani ndi RF MISO.
