Nkhani - Mfundo yogwirira ntchito ndi kuyambitsa kwa antenna ya nyanga ya broadband

Ma antenna a nyanga ya BroadbandNdi zipangizo zomwe zimagwiritsidwa ntchito pa ntchito yolumikizirana ndi ma frequency a wailesi kuti zitumize ndikulandira zizindikiro pa ma frequency osiyanasiyana. Zapangidwa kuti zipereke bandwidth yayikulu ndipo zimatha kugwira ntchito pa ma frequency angapo. Ma antenna a nyanga amadziwika kuti ndi okwera mtengo komanso owongolera, zomwe zimapangitsa kuti akhale oyenera kugwiritsa ntchito zosiyanasiyana monga kulumikizana opanda zingwe, machitidwe a radar, ndi kulumikizana kwa satellite. Amagwiritsidwa ntchito kwambiri pamaulalo olumikizirana a point-to-point, komwe kumafunika kutumiza deta yakutali komanso yamphamvu kwambiri. Kapangidwe ka antenna ya nyanga ya broadband kumaphatikizapo kusankha mosamala mawonekedwe ndi kukula kwa kapangidwe ka nyanga kuti mupeze bandwidth yayikulu yogwirira ntchito. Kapangidwe ka nyanga kamakula pang'onopang'ono kuchokera pakhosi lopapatiza kupita ku malo otseguka, zomwe zimathandiza kuti pakhale kufananiza bwino kwa impedance ndikugwira ntchito bwino pa ma frequency osiyanasiyana. Ma antenna a nyanga ya broadband amatha kupangidwa pogwiritsa ntchito zipangizo zosiyanasiyana, monga zitsulo kapena zida za dielectric, kutengera zofunikira zenizeni. Ma antenna a nyanga yachitsulo amagwiritsidwa ntchito kwambiri pa ntchito zamphamvu kwambiri, pomwe ma antenna a nyanga ya dielectric amakondedwa chifukwa cha kapangidwe kawo kopepuka komanso kakang'ono. Ndikofunikira kudziwa kuti ngakhale ma antenna a nyanga ya broadband amatha kuphimba ma frequency osiyanasiyana, magwiridwe antchito awo amatha kusiyana pa ma frequency osiyanasiyana. Kuchuluka kwa ma antenna, mawonekedwe a radiation, ndi kufananiza kwa impedance kungasinthe pamene kuchuluka kwa ma operating frequency kukusintha. Chifukwa chake, kusanthula koyenera ndi kuganizira kapangidwe ndikofunikira kuti zitsimikizire magwiridwe antchito abwino kwambiri pa bandwidth yomwe mukufuna.

Momwe imagwirira ntchito:

Mfundo yake yogwirira ntchito ndi iyi: Ma frequency aliwonse amafanana ndi resonator: Mu antenna ya broadband horn, ntchito ya broadband imatheka pogawa zizindikiro za ma frequency osiyanasiyana ku ma resonator osiyanasiyana. Resonator iliyonse imatha kukulitsa zizindikiro mkati mwa ma frequency enaake. Kapangidwe ka nyanga: Kapangidwe ka nyanga ya antenna ya broadband horn kamakhala ndi gawo lofunika. Mwa kupanga bwino kukula, mawonekedwe, kupindika ndi magawo ena a speaker, zizindikiro za ma frequency osiyanasiyana zimatha kufalikira ndikulunjika mkati mwa speaker. Kutumiza kwa Broadband: Pambuyo podutsa mu kapangidwe ka nyanga, antenna ya broadband horn imatha kutulutsa zizindikiro pama frequency angapo. Zizindikiro izi zimatumizidwa kudzera mu radiation ya mlengalenga ndipo zimatha kufalitsa broadband. Netiweki yofananira: Pofuna kuonetsetsa kuti antenna ya broadband horn ikugwirizana bwino ndi magwiridwe antchito, netiweki yofananira nthawi zambiri imawonjezedwa. Netiweki yofananira imakhala ndi ma capacitor ndi ma inductors ndipo imagwiritsidwa ntchito kusintha kulowerera kwa antenna kuti igwirizane ndi kulowerera kwa chingwe chotumizira. Kapangidwe ndi mfundo yogwirira ntchito ya antenna ya broadband horn ndizovuta kwambiri, ndipo zinthu monga kuchuluka kwa ma frequency a chizindikiro, mphamvu ya radiation, ndi kufananiza kwa impedance ziyenera kuganiziridwa mokwanira. Kawirikawiri imagwiritsidwa ntchito mu njira zolumikizirana za broadband, monga radar, satellite, kulumikizana ndi magalimoto, ndi zina zotero.
