Inta jeer ee signalka codsiga raadaarka baabuurta way kala duwan yihiin inta u dhaxaysa 30 iyo 300 GHz, xataa ilaa 24 GHz.Iyada oo la kaashanayo hawlaha wareegga kala duwan, calaamadahan waxaa lagu kala qaadaa iyada oo loo marayo teknoolajiyada kala duwan ee xariiqda gudbinta sida khadadka microstrip, khadadka strip, substrate isku dhafan waveguide (SIW) iyo coplanar waveguide dhulka (GCPW).Tignoolajiyadan khadka gudbinta ah (Jaantus. 1) waxaa badanaa lagu isticmaalaa inta jeer ee mikrowave, iyo marmarka qaarkood hirarka millimitirka.Qalabka laminateerka wareegga si gaar ah loogu isticmaalo xaaladdan soo noqnoqoshada badan ayaa loo baahan yahay.Khadka Microstrip, sida ugu fudud uguna badan ee loo isticmaalo tikniyoolajiyada wareegga xariiqda gudbinta, waxay gaari kartaa heerka shahaadooyinka wareegga sare iyadoo la adeegsanayo tikniyoolajiyadda farsamaynta wareegga caadiga ah.Laakin marka soo noqnoqoshada kor loo qaado inta jeer ee hirarka milimitirka, waxaa laga yaabaa inaysan ahayn khadka gudbinta wareegga ugu fiican.Xadhig kastaa wuxuu leeyahay faa'iidooyin iyo khasaare u gaar ah.Tusaale ahaan, inkasta oo khadka microstrip ay fududahay in la farsameeyo, waa in ay xalliso dhibaatada luminta shucaaca sare marka loo isticmaalo inta jeer ee hirarka millimitirka.
Jaantuska 1 Marka loo gudbayo soo noqnoqda hirarka milimitirka, naqshadeeyayaasha wareegga microwave waxay u baahan yihiin inay wajahaan doorashada ugu yaraan afar tignoolajiyada khadka gudbinta ee inta jeer ee microwave
Inkasta oo qaab-dhismeedka furan ee khadka microstrip uu ku habboon yahay isku xirka jirka, waxay sidoo kale keeni doontaa dhibaatooyin qaar ka mid ah soo noqnoqoshada sare.Xariiqda gudbinta microstrip, mowjadaha korantada (EM) waxay ku faafiyaan kaariyaha walxaha wareegga iyo substrate-ka dielectric, laakiin qaar ka mid ah hirarka korantada ayaa ku faafiya hawada ku wareegsan.Sababtoo ah qiimaha Dk ee hooseeya ee hawada, qiimaha Dk ee waxtarka leh ee wareegga ayaa ka hooseeya kan qalabka wareegga, kaas oo ay tahay in lagu tixgeliyo jilitaanka wareegga.Marka la barbar dhigo Dk hooseeya, wareegyada ka samaysan qalabka Dk sare waxay u muuqdaan inay carqaladeeyaan gudbinta hirarka elektromagnetic waxayna yareeyaan heerka faafinta.Sidaa darteed, qalabka wareegga Dk ee hooseeya waxaa badanaa lagu isticmaalaa wareegyada hirarka millimitirka.
Sababtoo ah waxaa jira shahaado gaar ah oo tamarta korantada ah ee hawada, wareegga xariiqda microstrip ayaa u soo bixi doonta dibadda hawada, oo la mid ah anteenada.Tani waxay keeni doontaa khasaaraha shucaaca aan loo baahnayn in wareegga line microstrip, iyo khasaaraha kordhin doonaa kororka soo noqnoqda, taas oo sidoo kale keentaa caqabadaha in naqshadeeyayaasha wareegga kuwaas oo baranaya line microstrip si ay u xaddido khasaaraha shucaaca wareegga.Si loo yareeyo khasaaraha shucaaca, xadhkaha microstrip waxaa lagu samayn karaa qalab wareeg ah oo leh qiime sare oo Dk ah.Si kastaba ha ahaatee, kororka Dk wuxuu hoos u dhigi doonaa heerka faafinta mawjadaha korantada (marka loo eego hawada), taasoo keenaysa isbeddelka marxaladda calaamadda.Hab kale ayaa ah in la yareeyo khasaaraha shucaaca iyadoo la isticmaalayo qalab wareeg khafiif ah si loo farsameeyo khadadka microstrip.Si kastaba ha ahaatee, marka la barbar dhigo qalabka wareegga dhumucdiisuna, qalabka wareegga khafiifka ah ayaa aad ugu nugul saamaynta ay ku leedahay naxaasta bireed dusha qallafsanaanta, taas oo sidoo kale keeni doonta isbedel wajiga signal gaar ah.
Inkasta oo qaabeynta wareegga xariiqda microstrip ay tahay mid fudud, wareegga xariiqda microstrip ee qaybta hirarka millimitirka waxay u baahan tahay xakamaynta dulqaadka saxda ah.Tusaale ahaan, ballaca kirishbooyada ee u baahan in si adag loo xakameeyo, iyo inta jeer ee badan, inta badan ee dulqaadku wuxuu noqon doonaa.Sidaa darteed, line microstrip in band soo noqnoqda ruxruxo millimeter waa mid aad u xasaasi u ah isbeddelka technology processing, iyo sidoo kale dhumucdiisuna waxay ka mid ah walxaha dielectric iyo copper in wax, iyo shuruudaha dulqaadashada ee cabbirka wareegga loo baahan yahay waa mid aad u adag.
Stripline waa tignoolajiyada khadka gudbinta wareegga la isku halayn karo, kaas oo door wanaagsan ka ciyaari kara inta jeer ee hirarka millimitirka.Si kastaba ha ahaatee, marka la barbar dhigo khadka microstrip, kirishbooyada stripline waxaa ku hareeraysan dhexdhexaadka ah, sidaas darteed ma fududa in xiriiriyaha ama wax-soo-saarka kale / dekedaha wax soo saarka ee stripline gudbinta signalada.Xarigga waxaa loo arki karaa inuu yahay nooc ka mid ah fiilada coaxial ee fidsan, kaas oo kirishtaanku uu ku duudduubay lakabka dielectric ka dibna lagu daboolo stratum.Qaab dhismeedkani wuxuu ku siin karaa saameyn tayo sare leh oo go'doominta wareegga, iyadoo lagu ilaalinayo faafinta calaamada qalabka wareegga (halkii ay ka ahaan lahayd hawada ku wareegsan).Hirarka korantada ayaa had iyo jeer ku faafta walxaha wareegga.Wareegga xariijinta waxaa lagu simi karaa iyadoo loo eegayo sifooyinka walxaha wareegga, iyada oo aan la tixgelinin saameynta mowjadda elektromagnetic ee hawada.Si kastaba ha ahaatee, kaari wareegga ah ee ku wareegsan dhexdhexaadku waxay u nugul yihiin isbeddelada tiknoolajiyada farsamaynta, iyo caqabadaha quudinta calaamaduhu waxay ku adkeynayaan xargaha si ay ula qabsadaan, gaar ahaan marka la eego xaaladda cabbirka yar ee isku xiraha ee inta jeer ee hirarka millimitirka.Sidaa darteed, marka laga reebo wareegyada qaarkood ee loo isticmaalo raadaarka baabuurta, xargaha xargaha inta badan laguma isticmaalo wareegyada hirarka millimitirka.
Sababtoo ah waxaa jira shahaado gaar ah oo tamarta korantada ah ee hawada, wareegga xariiqda microstrip ayaa u soo bixi doonta dibadda hawada, oo la mid ah anteenada.Tani waxay keeni doontaa khasaaraha shucaaca aan loo baahnayn in wareegga line microstrip, iyo khasaaraha kordhin doonaa kororka soo noqnoqda, taas oo sidoo kale keentaa caqabadaha in naqshadeeyayaasha wareegga kuwaas oo baranaya line microstrip si ay u xaddido khasaaraha shucaaca wareegga.Si loo yareeyo khasaaraha shucaaca, xadhkaha microstrip waxaa lagu samayn karaa qalab wareeg ah oo leh qiime sare oo Dk ah.Si kastaba ha ahaatee, kororka Dk wuxuu hoos u dhigi doonaa heerka faafinta mawjadaha korantada (marka loo eego hawada), taasoo keenaysa isbeddelka marxaladda calaamadda.Hab kale ayaa ah in la yareeyo khasaaraha shucaaca iyadoo la isticmaalayo qalab wareeg khafiif ah si loo farsameeyo khadadka microstrip.Si kastaba ha ahaatee, marka la barbar dhigo qalabka wareegga dhumucdiisuna, qalabka wareegga khafiifka ah ayaa aad ugu nugul saamaynta ay ku leedahay naxaasta bireed dusha qallafsanaanta, taas oo sidoo kale keeni doonta isbedel wajiga signal gaar ah.
Inkasta oo qaabeynta wareegga xariiqda microstrip ay tahay mid fudud, wareegga xariiqda microstrip ee qaybta hirarka millimitirka waxay u baahan tahay xakamaynta dulqaadka saxda ah.Tusaale ahaan, ballaca kirishbooyada ee u baahan in si adag loo xakameeyo, iyo inta jeer ee badan, inta badan ee dulqaadku wuxuu noqon doonaa.Sidaa darteed, line microstrip in band soo noqnoqda ruxruxo millimeter waa mid aad u xasaasi u ah isbeddelka technology processing, iyo sidoo kale dhumucdiisuna waxay ka mid ah walxaha dielectric iyo copper in wax, iyo shuruudaha dulqaadashada ee cabbirka wareegga loo baahan yahay waa mid aad u adag.
Stripline waa tignoolajiyada khadka gudbinta wareegga la isku halayn karo, kaas oo door wanaagsan ka ciyaari kara inta jeer ee hirarka millimitirka.Si kastaba ha ahaatee, marka la barbar dhigo khadka microstrip, kirishbooyada stripline waxaa ku hareeraysan dhexdhexaadka ah, sidaas darteed ma fududa in xiriiriyaha ama wax-soo-saarka kale / dekedaha wax soo saarka ee stripline gudbinta signalada.Xarigga waxaa loo arki karaa inuu yahay nooc ka mid ah fiilada coaxial ee fidsan, kaas oo kirishtaanku uu ku duudduubay lakabka dielectric ka dibna lagu daboolo stratum.Qaab dhismeedkani wuxuu ku siin karaa saameyn tayo sare leh oo go'doominta wareegga, iyadoo lagu ilaalinayo faafinta calaamada qalabka wareegga (halkii ay ka ahaan lahayd hawada ku wareegsan).Hirarka korantada ayaa had iyo jeer ku faafta walxaha wareegga.Wareegga xariijinta waxaa lagu simi karaa iyadoo loo eegayo sifooyinka walxaha wareegga, iyada oo aan la tixgelinin saameynta mowjadda elektromagnetic ee hawada.Si kastaba ha ahaatee, kaari wareegga ah ee ku wareegsan dhexdhexaadku waxay u nugul yihiin isbeddelada tiknoolajiyada farsamaynta, iyo caqabadaha quudinta calaamaduhu waxay ku adkeynayaan xargaha si ay ula qabsadaan, gaar ahaan marka la eego xaaladda cabbirka yar ee isku xiraha ee inta jeer ee hirarka millimitirka.Sidaa darteed, marka laga reebo wareegyada qaarkood ee loo isticmaalo raadaarka baabuurta, xargaha xargaha inta badan laguma isticmaalo wareegyada hirarka millimitirka.
Jaantuska 2 Naqshadeynta iyo jilitaanka kaareeyaha wareegga GCPW waa leydi (shaxanka sare), laakiin kaari waxaa loo farsameeyaa trapezoid (shaxan hoose), kaas oo saameyn kala duwan ku yeelan doona inta jeer ee hirarka millimitirka.
Codsiyada wareegga hirarka millimitirka ee soo baxaya ee xasaasiga u ah jawaabta wajiga (sida radar baabuurta), sababaha iswaafaq la'aanta wajiga waa in la yareeyaa.Wareegga milimitirka ee inta jeer ee hirarka GCPW wuxuu u nugul yahay isbeddelada agabka iyo farsamada farsamaynta, oo ay ku jiraan isbeddelada qiimaha Dk ee walxaha iyo dhumucda substrate-ka.Marka labaad, waxqabadka wareegga waxaa laga yaabaa inuu saameeyo dhumucda kooraska naxaasta iyo qallafsanaanta dusha sare ee biibiile naxaas ah.Sidaa darteed, dhumucda korriinka naxaasta waa in lagu hayaa dulqaad adag, iyo qallafsanaanta dusha sare ee foornada naxaasta waa in la yareeyo.Marka saddexaad, doorashada dahaarka dusha sare ee wareegga GCPW waxa kale oo laga yaabaa inay saamayso waxqabadka hirarka millimitirka ee wareegga.Tusaale ahaan, wareegga isticmaalaya dahabka nikelka kiimikaad wuxuu leeyahay khasaaro ka badan nikkel marka loo eego naxaasta, iyo lakabka kore ee nikelku wuxuu kordhin doonaa luminta khadka GCPW ama microstrip (Jaantuska 3).Ugu dambeyntii, sababtoo ah hirarka yar yar, isbedelka dhumucdiisuna waxay sidoo kale keeni doontaa isbeddelka jawaabta wajiga, iyo saamaynta GCPW waa ka weyn yahay in line microstrip.
Jaantus 3 Xariiqda microstrip iyo wareegga GCPW ee shaxanka lagu muujiyey waxay isticmaalaan agab wareeg isku mid ah (Rogers '8mil dhumucdiisuna tahay RO4003C ™ Laminate), saamaynta ENIG ee wareegga GCPW ayaa aad uga weyn tan khadka microstrip ee inta jeer ee hirarka millimitirka.
