Game da eriya, nan don gaya muku ~

Eriya, wadda za a iya amfani da ita don isar da sigina da karɓar sigina, mai jujjuyawa ce, tana da daidaito, kuma ana iya ɗaukarta azaman transducer, wanda shine na'urar mu'amala tsakanin kewayawa da sarari.Lokacin da aka yi amfani da shi don isar da sigina, siginonin lantarki masu tsayin da aka samar ta hanyar siginar siginar suna juyar da igiyoyin lantarki a sararin samaniya kuma suna fitarwa ta wata hanya.Lokacin amfani da shi don karɓar sigina, igiyoyin lantarki na lantarki a sararin samaniya suna juyar da siginar lantarki kuma ana watsa su zuwa mai karɓa ta hanyar kebul.

Kowane eriya yana da wasu sifofi masu siffa waɗanda za a iya siffanta su yadda ya kamata, waɗanda za a iya amfani da su don kimanta aikin eriya, gami da sigogin halayen lantarki da sigogin halayen injina.

Rarraba eriya

Ana iya rarraba eriya ta hanyoyi daban-daban, musamman:

Rarraba ta amfani: ana iya raba shi zuwa eriyar sadarwa, eriyar talabijin, eriyar radar da sauransu

Dangane da rabe-raben bandeji mai aiki: ana iya raba shi zuwa eriyar gajeriyar igiyar ruwa, eriyar gajeriyar gajeriyar hanya, eriyar microwave da sauransu.

Dangane da rarrabuwar kai tsaye: ana iya raba shi zuwa eriya ta gaba ɗaya, eriya ta jagora, da sauransu

Dangane da rarrabuwar siffa: ana iya raba shi zuwa eriya na layi, eriya mai tsari da sauransu

Eriya ta Hannu: Hanyar eriya ta iyakance zuwa madaidaiciyar shugabanci na ƙasa da digiri 360.

Ana iya amfani da eriya ta gaba ɗaya sau da yawa don karɓa/ watsa sigina a duk kwatance a lokaci guda.Wannan na iya zama abin kyawawa idan ana buƙatar sigina da ake buƙatar karɓa/ watsawa a duk kwatance, kamar tare da wasu tashoshin rediyo na gargajiya.Koyaya, akwai lokuta da yawa inda aka san alkiblar siginar ko iyakance.Misali, tare da na'urar hangen nesa ta rediyo, an san cewa za a karɓi sigina ta wata hanya da aka bayar (daga sararin samaniya), yayin da eriya ta gaba ɗaya ba ta da inganci wajen ɗaukar sigina marasa ƙarfi daga taurari.A wannan yanayin, ana iya amfani da eriya ta jagora tare da babbar riba ta eriya don karɓar ƙarin ƙarfin sigina a wata hanyar da aka bayar.

Misalin eriya mai matuƙar jagora shine eriyar Yagi.Waɗannan nau'ikan eriya mitoci ne da ake amfani da su don aika/karɓar siginar sadarwa ta nisa mai nisa lokacin da aka san alkiblar siginar shigarwa ko manufa.Wani misali na eriya mai matuƙar jagora shine eriyar ribar ƙaho.Ana amfani da waɗannan eriya galibi don aikace-aikacen gwaji da aunawa, kamar lokacin auna aikin wata eriya, ko lokacin karɓar/aika sigina a cikin mitar mitar raƙuman ruwa mafi girma.Hakanan za'a iya kera eriya ta hanya a cikin ƙirar faranti mara nauyi don ƙirƙira mai sauƙi akan abubuwan RF na gama gari kamar PCBS.Ana amfani da waɗannan eriya mai lebur a cikin sadarwar mabukaci da masana'antu saboda ba su da tsadar ƙira kuma suna da nauyi da ƙanana.
