Mvetsetsani ntchito ndi mawonekedwe ogwiritsira ntchito ma waveguide probes

Mbiri

Mlongoti wa nyanga ya Broadband ndi mlongoti womwe umagwiritsidwa ntchito pofalitsa mafunde amagetsi, ndipo mbiri yake imachokera kuzaka za m'ma 1930. Mlongoti wa nyanga ya burodibandi unapangidwa koyamba ndi katswiri wa zakuthambo wa ku America Karl Guthe Jansky mu 1932. Anagwiritsa ntchito mlongoti wa "nyanga" wopangidwa mwapadera kuti alandire ndi kuyeza mafunde a wailesi m'chilengedwe. Mapangidwe a mlongoti wa nyanga ya Broadband amalimbikitsidwa ndi lipenga lomveka ndipo amapangidwa ngati lipenga kuti akweze chizindikiro cholandilidwa ndi mlongoti. Kwazaka makumi angapo zotsatira, tinyanga za nyanga za Broadband zidasinthidwa mosalekeza ndikupangidwa, kukhala chida chofunikira cholumikizirana opanda zingwe komanso chida chowonera zakuthambo. Masiku ano, tinyanga za nyanga za Broadband zimagwiritsidwa ntchito kwambiri pamalumikizidwe opanda zingwe, makina a radar, miyeso yosokoneza ma wailesi, mavuni a microwave ndi magawo ena, ndipo mapangidwe awo ndi magwiridwe ake akhala akuwongolera ndikuwongolera mosalekeza. Mbiri ya nyanga za Broadband horn tinganene kuti ndi gawo lofunika kwambiri pa chitukuko cha mauthenga opanda zingwe komanso kuwunika zakuthambo.

Kapangidwe ndi mfundo:

Chofunikira chachikulu cha mlongoti wa nyanga ya Broadband ndi mawonekedwe ake ngati nyanga. Nthawi zambiri imakhala ndi kalozera kachitidwe ka nyanga yokulitsa pang'onopang'ono, momwe nyanga ya nyanga imachulukira pang'onopang'ono. Kutalika ndi mawonekedwe a kalozera kalozera zimatengera mtundu womwe mukufuna komanso magwiridwe antchito.

Mfundo yogwiritsira ntchito nyanga ya Broadband horn imatengera mawonekedwe a nyanga omwe akukulira pang'onopang'ono mu kalozera. Pamene chizindikiro chikudutsa mu mlongoti wa nyanga, mawonekedwe otsogolera amakulitsa pang'onopang'ono chizindikirocho kuchokera ku ting'onoting'ono tating'ono kupita kumalo akuluakulu. Kukula kumeneku kumathandizira kuti mlongoti wa nyanga uwoneke bwino ndikulandila ma siginecha pa bandi yayikulu chifukwa ma frequency osiyanasiyana amatha kuwulutsidwa ndikulandilidwa m'magawo osiyanasiyana a nyanga.

Mawonekedwe ndi Mapulogalamu:

1. Mawonekedwe a Broadband: Mapangidwe a mlongoti wa nyanga ya Broadband amalola kuti azigwira ntchito mkati mwa bandi yayikulu. Itha kuphimba ma frequency angapo, kuyambira mazana a megahertz mpaka ma gigahertz angapo kapena kupitilira apo. Izi zimapangitsa kuti tinyanga ta nyanga za wideband zikhale zabwino pazogwiritsa ntchito zomwe zimafuna kusinthidwa kwa ma siginecha amagulu ambiri, monga kulumikizana, miyeso ya radar ndi RF.

2. Mawonekedwe a radiation yowongoka: Mlongoti wa nyanga ya Broadband uli ndi mawonekedwe a radiation yathyathyathya, ndiye kuti, ili ndi mawonekedwe ofananirako mkati mwa ngodya zambiri. Izi zikutanthauza kuti imatha kuwunikira ndikulandila ma siginecha bwino pamaulendo osiyanasiyana popanda kupotoza kwambiri.

3. Ma radiation otsika a m’mbali mwa mbali: Tinyanga za nyanga ya Broadband nthawi zambiri zimakhala ndi cheza chochepa cham’mbali, ndiko kuti, palibe cheza chodziwikiratu chowonjezera kupatulapo lobe yaikulu. Izi zimapangitsa kuti zikhale zothandiza m'mapulogalamu omwe zizindikiro zosokoneza ziyenera kuchepetsedwa kapena kuchotsedwa.

4. Kulekerera kwamphamvu kwamphamvu: Nyanga za nyanga za Broadband nthawi zambiri zimakhala ndi mphamvu zololera. Kukhoza kwawo kugwiritsira ntchito ma siginecha apamwamba kwambiri kumawapangitsa kukhala oyenera kugwiritsa ntchito mphamvu zapamwamba monga radar ndi njira zolumikizirana.

5. Zosavuta komanso zodalirika: Kapangidwe ka mlongoti wa nyanga ya Broadband ndi wosavuta komanso wosavuta kupanga ndikuyika. Nthawi zambiri amapangidwa ndi zitsulo zachitsulo, monga aluminiyamu kapena mkuwa, kuti zikhale zolimba komanso zodalirika.

Chidule:

Mlongoti wa nyanga za Broadband ndi mlongoti womwe umatha kugwira ntchito mkati mwa bandi yayikulu. Ili ndi mawonekedwe a gulu lalikulu, mawonekedwe amtundu wathyathyathya, ma radiation otsika a mbali ya lobe, mphamvu yogwiritsira ntchito mphamvu, ndipo ndi yosavuta komanso yodalirika. Nyanga za nyanga za Broadband zimagwiritsidwa ntchito kwambiri polumikizirana, radar, kuyeza ma frequency a wailesi ndi kafukufuku wasayansi ndi magawo ena kuti aziwunikira ndikulandila ma siginecha a Broadband.
