Nkhani - Mfundo yogwira ntchito ndikuyambitsa mlongoti wa nyanga za Broadband

Zinyanga za Broadband Hornndi zida zomwe zimagwiritsidwa ntchito polumikizirana ndi mawayilesi kuti azitumiza ndikulandila ma siginoloji pama frequency osiyanasiyana.Zapangidwa kuti zipereke chiwongolero chochuluka ndipo zimatha kugwira ntchito pamagulu angapo afupipafupi.Nnyanga za Horn zimadziwika chifukwa cha kupindula kwakukulu ndi kuwongolera, zomwe zimawapangitsa kukhala oyenerera ntchito zosiyanasiyana monga mauthenga opanda waya, machitidwe a radar, ndi mauthenga a satana.Amagwiritsidwa ntchito kawirikawiri pamalumikizidwe oyankhulana ndi mfundo, komwe kumayenera kutumiza deta kwautali ndi mphamvu zambiri. .Maonekedwe a nyanga pang'onopang'ono amakula kuchokera ku mmero wopapatiza kupita ku kabowo kokulirapo, komwe kumapangitsa kufananiza kwabwinoko ndikuchita bwino pamitundu yosiyanasiyana. zofunika.Minyanga yachitsulo yachitsulo imagwiritsidwa ntchito kwambiri pogwiritsira ntchito mphamvu zambiri, pamene manyanga a dielectric amawakonda chifukwa cha mawonekedwe awo opepuka komanso ophatikizika.Ndikoyenera kudziwa kuti ngakhale tinyanga za nyanga za Broadband zimatha kuphimba ma frequency osiyanasiyana, machitidwe awo amatha kusiyanasiyana pama band osiyanasiyana.Kupindula kwa antenna, mawonekedwe a radiation, ndi kufananiza kwa ma impedance kungasinthe momwe ma frequency ogwirira ntchito asinthira.Chifukwa chake, kusanthula koyenera ndi kulingalira koyenera ndikofunikira kuti muwonetsetse kuti magwiridwe antchito abwino pa bandwidth yomwe mukufuna.

Momwe zimagwirira ntchito:

Mfundo yake yogwirira ntchito ndi motere: Mafupipafupi aliwonse amafanana ndi resonator: Mu mlongoti wa nyanga ya Broadband, ntchito ya Broadband imatheka pogawa zizindikiro za ma frequency osiyanasiyana kwa ma resonator osiyanasiyana.Resonator iliyonse imatha kukulitsa ma signature mkati mwa ma frequency angapo.Kapangidwe ka nyanga: Kapangidwe ka nyanga ya mlongoti wa nyanga ya Broadband amatenga gawo lofunikira.Mwa kupanga mwanzeru kukula, mawonekedwe, kupindika ndi magawo ena a wokamba nkhani, ma sign a ma frequency osiyanasiyana amatha kufalikira ndikukhazikika mkati mwa wokamba nkhani.Kutumiza kwa Broadband: Pambuyo podutsa pamapangidwe a nyanga, mlongoti wa nyanga ya Broadband umatha kuwunikira ma frequency angapo.Zizindikirozi zimafalitsidwa kudzera mumlengalenga ndipo zimatha kufalitsa ma burodi.Kufananiza maukonde: Pofuna kuwonetsetsa kuti magwiridwe antchito ndi kufananiza kwa mlongoti wa nyanga ya Broadband, netiweki yofananira nthawi zambiri imawonjezedwa.Netiweki yofananira imakhala ndi ma capacitor ndi ma inductors ndipo imagwiritsidwa ntchito kusinthira kulowetsedwa kwa mlongoti kuti igwirizane ndi kutsekeka kwa chingwe chotumizira.Mapangidwe ndi mfundo zogwirira ntchito za mlongoti wa nyanga ya Broadband ndizovuta kwambiri, ndipo zinthu monga kuchuluka kwa ma siginecha, kugwiritsa ntchito bwino kwa ma radiation, komanso kufananitsa kwa impedans ziyenera kuganiziridwa bwino.Nthawi zambiri amagwiritsidwa ntchito pamakina olumikizirana ma burodibandi, monga ma radar, ma satellite, kulumikizana kwamagalimoto, ndi zina.
