Mbiri ya tinyanga ta nyanga inayamba mu 1897, pamene wofufuza pa wailesi, Jagadish Chandra Bose, anachita upainiya woyesera pogwiritsa ntchito ma microwave.Pambuyo pake, GC Southworth ndi Wilmer Barrow adapanga mapangidwe a nyanga yamakono mu 1938 motsatana.Kuyambira pamenepo, mapangidwe a antenna anyanga akhala akuphunziridwa mosalekeza kuti afotokoze momwe ma radiation awo amayendera komanso momwe amagwiritsidwira ntchito m'magawo osiyanasiyana.Ma antennawa ndi otchuka kwambiri pamayendedwe otumizira ma waveguide ndi ma microwave, chifukwa chake amatchedwa.ma microwave antennas.Chifukwa chake, nkhaniyi iwunika momwe tinyanga ta nyanga zimagwirira ntchito ndikugwiritsa ntchito m'magawo osiyanasiyana.
Kodi mlongoti wa nyanga ndi chiyani?
A mlongoti wa nyangandi kabowo kakang'ono kamene kamapangidwira ma frequency a microwave omwe amakhala ndi malekezero otambasuka kapena ngati nyanga.Kapangidwe kameneka kamapangitsa kuti mlongoti ukhale wowongoka kwambiri, zomwe zimapangitsa kuti chizindikiro chotuluka chizifalikira mosavuta patali.Nyanga za Horn zimagwira ntchito pafupipafupi pa ma microwave, motero ma frequency awo amakhala UHF kapena EHF.
RFMISO nyanga mlongoti RM-CDPHA618-20 (6-18GHz)
Tinyangazi zimagwiritsidwa ntchito ngati nyanga zodyetsa tinyanga zazikulu monga parabolic ndi zolunjika.Ubwino wawo umaphatikizapo kuphweka kwa mapangidwe ndi kusintha, kutsika kwa mafunde otsika, kuwongolera pang'ono, ndi bandwidth yaikulu.
Mapangidwe a antenna a Nyanga ndi ntchito
Mapangidwe a antenna a Horn amatha kukhazikitsidwa pogwiritsa ntchito ma waveguide okhala ngati nyanga potumiza ndikulandila ma radio frequency ma microwave ma siginecha.Nthawi zambiri, amagwiritsidwa ntchito molumikizana ndi ma feed a waveguide ndi mafunde achindunji a wailesi kuti apange matabwa opapatiza.Gawo loyaka moto limatha kukhala ndi mawonekedwe osiyanasiyana, monga masikweya, conical, kapena amakona anayi.Kuonetsetsa kuti ntchito yoyenera, kukula kwa mlongoti uyenera kukhala wochepa kwambiri.Ngati kutalika kwa mafunde ndi kwakukulu kwambiri kapena kukula kwa nyanga kuli kochepa, mlongoti sugwira ntchito bwino.
Chojambula cha antenna a Horn
Mu mlongoti wa nyanga, mbali ina ya mphamvu ya chochitikacho imawululidwa kunja kwa khomo la waveguide, pamene mphamvu zonse zimawonekera kumbuyo kuchokera pakhomo lomwelo chifukwa khomo liri lotseguka, zomwe zimapangitsa kuti pakhale kusagwirizana pakati pa malo ndi waveguide.Kuphatikiza apo, m'mphepete mwa waveguide, diffraction imakhudza mphamvu yowunikira ya waveguide.
Pofuna kuthana ndi zofooka za waveguide, kutsegulira komaliza kumapangidwa ngati nyanga ya electromagnetic.Izi zimathandiza kuti pakhale kusintha kosalala pakati pa danga ndi waveguide, kupereka chiwongolero chabwino cha mafunde a wailesi.
Posintha mawonekedwe a waveguide ngati nyanga, discontinuity ndi 377 ohm impedance pakati pa danga ndi waveguide imathetsedwa.Izi zimakulitsa chiwongolero ndi kupindula kwa mlongoti wotumizira pochepetsa kusuntha kwa m'mphepete kuti ipereke mphamvu ya zochitika zomwe zimaperekedwa kutsogolo.
Umu ndi momwe mlongoti wa nyanga umagwirira ntchito: Mbali imodzi ya ma waveguide ikakondwa, mphamvu ya maginito imapangidwa.Pankhani ya kufalitsa kwa waveguide, gawo lofalitsa likhoza kuwongoleredwa kudzera m'makoma a waveguide kuti munda usafalikire mozungulira koma mofanana ndi kufalitsa kwaufulu.Munda wodutsa ukafika kumapeto kwa waveguide, umafalikira mofanana ndi malo aulere, kotero kuti mzere wozungulira wozungulira umapezeka kumapeto kwa waveguide.
Mitundu yodziwika bwino ya tinyanga ta nyanga
Mlongoti wa Horn wa Standard Gainndi mtundu wa mlongoti womwe umagwiritsidwa ntchito kwambiri pamakina olankhulirana omwe ali ndi phindu lokhazikika komanso kutalika kwake.Mlongoti wamtunduwu ndi woyenera kugwiritsa ntchito zambiri ndipo ukhoza kupereka chidziwitso chokhazikika komanso chodalirika cha zizindikiro, komanso kutulutsa mphamvu kwamphamvu kwambiri komanso luso loletsa kusokoneza.Ma antennas a horn gain nthawi zambiri amagwiritsidwa ntchito kwambiri pama foni am'manja, kulumikizana kosasunthika, kulumikizana kwa satellite ndi magawo ena.
