Anteenooyinka daloolka waa nooc muhiim ah oo anteenooyin ah oo si weyn loogu isticmaalo nidaamyada cabbirka microwave-ka, millimitir-hir, radar, isgaarsiinta, iyo anteenooyinka. Si ka duwan anteenooyinka siligga ah, kuwaas oo inta badan ka soo baxa hirarka ku socda walxaha gudbiya, anteenooyinka daloolka waxay ka soo baxaan tamarta elektromagnetic-ka iyada oo loo marayo furitaan ama dalool.
Tusaale caadi ah waa hagaha hirarka ee furan. Marka hirarka elektromagnetic-ku ay dhex maraan hagaha hirarka oo ay gaaraan dhammaad furan, qayb ka mid ah tamarta la hago ayaa lagu shubaa meel bannaan. Iyagoo xakameynaya joomatarigga daloolka, qaybinta goobta, iyo qaab-dhismeedka ku xeeran, injineeradu waxay sii wanaajin karaan isku-xidhka is-dhexgalka, toosnaanta, faa'iidada, iyo astaamaha shucaaca.
Anteenooyinka nooca furan ee caadiga ah waxaa ka mid ahanteenooyinka hagaha hirarka ee furan,anteenooyinka geeska, iyo anteenooyinka booskaMaqaalka asalka ah ee tixraaca ayaa sidoo kale saddexdan qaab-dhismeed ku kala soocaya anteenooyinka daloolka.
1. Waa maxay Anteenada Afka laga furo?
Injineernimada anteenada, daloolka waxaa loo tixgelin karaa furitaan ay goobaha elektromagnetic-ka ah ku xidhmaan qaab-dhismeed la hagayo una gudbaan meel bannaan.
Hagaha hirarka waxaa loogu talagalay inuu xaddido oo hago tamarta elektromagnetic-ka. Haddii hagaha hirarka uu joojiyo derbi gudbiye ah, tamartu waxay ahaanaysaa mid xaddidan ama waxay ka muuqataa xaaladaha joojinta. Si kastaba ha ahaatee, marka hagaha hirarka la furo, goobta elektaroonigga ah ee ku taal daloolka ayaa ku faafta meel bannaan.
Sidaas darteed daloolku wuxuu u shaqeeyaa sidii gobolka kala-guurka ee u dhexeeya qaabka elektaroonigga ah ee la hago iyo hirarka elektaroonigga ah ee la iftiimiyo.
Astaamaha shucaaca dhabta ah waxay ku xiran yihiin dhowr arrimood, oo ay ku jiraan:
- Cabbirrada iyo qaabka daloolka
- Mowjadda hawlgalka
- Qaabka hagaha hirarka
- Qaybinta garoonka korontada iyo birlabta
- Qaab-dhismeedka qabsashada ama hareeraha ee Flange-ka
- Iswaafajinta Impedance ee furitaanka
Cilmi-baaris lagu sameeyay hagaha hirarka leydi-wareegga ee furan ayaa muujinaya in goobaha daloolinta iyo kala-soocidda ka timaadda geesaha flange-ka ee ku wareegsan ay gacan ka geysan karaan goobta shucaaca leh ee ka dhalata.
Jaantuska 1. Tusaale qaab-dhismeedka hagaha hirarka ee afargeeslaha ah ee loo isticmaalo in lagu muujiyo shucaaca daloolka.
2. Sidee buu u iftiimaa Hagaha Hirarka ee Furan?
Marka habka hagaha hirarka faafinaya uu gaaro dalool furan, xaaladaha xuduudaha elektromagnetic-ka ayaa si lama filaan ah isu beddela. Beeraha hadda si buuxda uma xaddidaan derbiyada wax qabta, taasoo u oggolaanaysa qayb ka mid ah tamarta elektromagnetic-ka inay ku faafto meel bannaan.
Isla mar ahaantaana, kala-guurka laga bilaabo hagaha hirarka una gudbayo booska xorta ah guud ahaan si fiican uma eka. Sidaa darteed, tamar qaar ayaa laga yaabaa inay dib ugu soo noqoto hagaha hirarka.
Xiriirkan ka dhexeeyashucaac iyo milicsiwaa qayb muhiim ah oo ka mid ah naqshadaynta anteenada aperture.
Hagaha hirarka ee furan wuxuu u shaqayn karaa sidii anteeno, laakiin waxtarkeeda shucaaca, isku-dhafka is-hortaagga, faa'iidada, iyo astaamaha iftiinka ayaa laga yaabaa inaysan ku habboonayn codsi kasta. Injineeradu waxay wax ka beddeli karaan qaab-dhismeedka daloolka si ay u helaan waxqabad wanaagsan. Mid ka mid ah tusaalooyinka ugu caansan waaanteenada geeska, kaas oo hagaha hirarku si tartiib tartiib ah ugu fido dhanka daloolka.
3. Soo noqnoqoshada Hawlgalka Anteenooyinka Daloolada
Ma jiro hal nooc oo soo noqnoqoshada hawlgalka guud ah oo loogu talagalay dhammaan anteenooyinka aperture-ka.
Kala duwanaanshaha soo noqnoqoshada ee anteenada aperture-ka ku salaysan hagaha mawjadaha waxaa ugu horreyn lagu go'aamiyaaCabbirrada hagaha hirarka, nooca hagaha hirarka, qaababka faafinta ee la taageerayo, iyo soo noqnoqoshada goynta.
Sidaa darteed, cabbirro kala duwan oo hagaha hirarka ah ayaa loo isticmaalaa noocyada kala duwan ee hirarka microwave-ka iyo milimitir-hirarka.
Tani waxay si gaar ah muhiim ugu tahay nidaamyada RF-ga ee soo noqnoqda sare leh. Marka soo noqnoqoshadu korodho oo hirarka hirarku uu gaabiyo, cabbirrada hagaha hirarka iyo daloolka ayaa sidoo kale yaraaday, taasoo u oggolaanaysa anteenooyinka furfuran in si wax ku ool ah loogu isticmaalo microwave-ka, hirarka milimitir-ka, iyo xitaa nidaamyada hoose ee THz.
4. Qaabka Shucaaca ee Anteenada Daloosha
Qaabka shucaaca ee anteenada daloolka waxay si xooggan ugu xiran tahay cabbirka daloolka, qaybinta goobta, qaabka hawlgalka, hirarka hirarka, iyo qaab-dhismeedka ku xeeran.
Hagaha hirarka ee furan guud ahaan wuxuu soo saaraa iftiin ballaaran, laakiin waa in aan si toos ah loogu tilmaamin anteeno dhinac walba ah. Astaamaha shucaaca E-plane iyo H-plane waxaa go'aamiya qaybinta goobta elektromagnetic-ka ee ka sarreysa daloolka.
Flange-ka ku wareegsan wuxuu sidoo kale saameyn karaa qaabka shucaaca ee ka dhasha sababtoo ah beeraha ka kala fog geesaha ayaa gacan ka geysta guud ahaan goobta shucaaca. Daraasadaha casriga ah ee falanqaynta ayaa si cad u qeexaya shucaaca daloolka iyo kala-soocidda geeska flange-ka marka la xisaabinayo dhaqanka goobta fog.
Kordhinta cabbirka daloolka wax ku oolka ah guud ahaan waxay bixin kartaa toosin sare iyo iftiin weyn oo cidhiidhi ah, waana mid ka mid ah sababaha anteenooyinka geeska iyo qaab-dhismeedka daloolka weyn loo isticmaalo marka loo baahdo faa'iido sare.

5. Noocyada ugu Muhiimsan ee Anteenooyinka Furitaanka
Anteenada Hagaha Mowjadaha ee Dhammaadka Furan
Hagaha hirarka ee furan waa mid ka mid ah kuleyliyeyaasha ugu fudud ee aperture-ka. Qaab-dhismeedkiisa yar iyo iswaafajinta tooska ah ee nidaamyada hagaha hirarka ayaa ka dhigaya mid waxtar leh shaybaarada microwave-ka iyo millimeter-ka-hirarka, cabbiraadaha anteenooyinka, baarayaasha, quudinta, iyo nidaamyada kale ee RF.
Anteenada geeska
Anteenada geeska waxaa loo arki karaa hagaha hirarka oo qaybtiisa isgoyska ah ay si tartiib tartiib ah ugu fiddo daloolka shucaaca. Kala-guurkan tartiib-tartiibka ah wuxuu hagaajiyaa isbeddelka laga bilaabo hirarka la hago ilaa shucaaca bannaanka ah wuxuuna bixin karaa is-waafajin ka wanaagsan, faa'iido sare, iyo qaabab shucaac oo la xakameeyey.
Anteenooyinka geeska waxaa si weyn loogu isticmaalaa cabbirka anteenada, tijaabada EMC, radar, nidaamyada isgaarsiinta, nidaamyada quudinta, iyo codsiyada hirarka millimeter-ka.
Anteenada booska
Anteenada godka waxay isticmaashaa furitaan ama god laga jaray dusha sare ee hagaya si ay u iftiimiso tamarta elektromagnetic-ka. Iyada oo ku xidhan qaab-dhismeedka godka, kicinta, iyo qaab-dhismeedka ku xeeran, anteenooyinka godka waxaa si gaar ah loo hirgelin karaa ama loogu dari karaa taxane.
Waxaa si weyn loogu isticmaalaa nidaamyada microwave-ka halkaas oo loo baahan yahay qaab-dhismeedyo hooseeya, isku-dhafan, ama qaab-dhismeedyo taxane ah.
6. Anteenooyinka daloolka ee injineernimada RF iyo Microwave-ka
Maadaama anteenooyinka daloolku si dabiici ah ula falgalaan qaab-dhismeedka gudbinta hagaha hirarka, waxay si gaar ah muhiim ugu yihiin mawjadaha microwave-ka iyo hirarka milimitir-ka.
Codsiyada caadiga ah waxaa ka mid ah:
- Cabbirka faa'iidada anteenada iyo qaabka shucaaca
- Tijaabada EMC iyo EMI
- Nidaamyada radar
- Isgaarsiinta Microwave-ka iyo milimitir-hirarka
- Nidaamyada quudinta anteenada
- Cabbirka shaybaadhka RF
- Gudbinta jihada iyo soo dhawaynta
- Nidaamyada tijaabada iyo qiyaasidda
Injineerada anteenada, doorashada anteeno furan oo ku habboon waxay u baahan tahay wax ka badan tixgelinta soo noqnoqoshada. Cabbirrada sida faa'iidada, beamwidth, polarization, VSWR, cabbirka hagaha hirarka, nooca flange, maaraynta awoodda, iyo cabbirrada farsamada ayaa dhammaantood saameyn kara waxqabadka nidaamka.
Gunaanad
Anteenooyinka daloolka waxay bixiyaan hab wax ku ool ah oo lagu beddelo tamarta elektaroonigga ah ee la hago shucaaca bannaanka, taasoo ka dhigaysa qayb anteeno aasaasi ah oo ku jirta injineernimada microwave-ka iyo hirarka milimitir-ka.
Laga bilaabo hagaha mowjadaha furan ee fudud ilaa qaab-dhismeedka geeska iyo booska la hagaajiyay, anteenooyinka aperture-ka waxaa loogu talagalay isku-darka kala duwan ee faa'iidada, beamwidth-ka, kala-goynta, heerka soo noqnoqda, iyo shuruudaha isku-dhafka nidaamka.
Sidaa darteed, fahamka sida cabbirka daloolka, qaybinta goobta elektromagnetic-ka, qaababka hagaha hirarka, iyo qaab-dhismeedka ku xeeran ay u saameeyaan waxqabadka shucaaca ayaa lagama maarmaan ah marka la dooranayo ama la naqshadaynayo anteenooyinka loogu talagalay tijaabinta RF, isgaarsiinta, radar, iyo nidaamyada cabbirka.
