Qaab-dhismeedka aanteenada microstripGuud ahaan waxay ka kooban tahay substrate dielectric ah, radiator iyo saxan dhulka ah. Dhumucda substrate-ka dielectric aad ayay uga yar tahay hirarka. Lakabka birta khafiifka ah ee ku yaal salka hoose ee substrate-ka wuxuu ku xiran yahay saxanka dhulka. Dhinaca hore, lakab bir ah oo khafiif ah oo leh qaab gaar ah ayaa laga sameeyaa habka sawir-qaadista sida radiator. Qaabka saxanka shucaaca waxaa loo beddeli karaa siyaabo badan iyadoo loo eegayo shuruudaha.
Kobaca tiknoolajiyada isku-dhafka microwave-ka iyo hababka wax-soo-saarka cusub ayaa kor u qaaday horumarinta anteenooyinka microstrip. Marka la barbardhigo anteenooyinka dhaqameed, anteenooyinka microstrip ma aha oo kaliya cabbir yar, miisaan fudud, muuqaal hooseeya, si fudud loo waafajin karo, si fudud loo dhexgelin karo, kharash yar, iyo ku habboon wax-soo-saarka ballaaran, laakiin sidoo kale waxay leeyihiin faa'iidooyinka sifooyinka korantada ee kala duwan.
Afarta hab ee quudinta aasaasiga ah ee anteenooyinka microstrip waa sidan soo socota:
1. (Quudinta Microstrip): Kani waa mid ka mid ah hababka quudinta ugu badan ee anteenooyinka microstrip. Calaamadda RF waxaa loo gudbiyaa qaybta shucaaca ee anteenada iyada oo loo marayo khadka microstrip, badanaa iyada oo loo marayo isku xidhka khadka microstrip iyo balastarada shucaaca. Habkani waa mid fudud oo dabacsan oo ku habboon naqshadeynta anteenooyin badan oo microstrip ah.
2. (Quudinta Aperture-ku xiran): Habkani wuxuu adeegsadaa godadka ama godadka ku yaal saxanka saldhigga anteenada microstrip si uu khadka microstrip ugu shubo qaybta shucaaca ee anteenada. Habkani wuxuu bixin karaa isku-habeyn ka wanaagsan oo ka hortag ah iyo hufnaan shucaac, wuxuuna sidoo kale yareyn karaa ballaca jiifka toosan iyo kan toosan ee godadka dhinaca.
3. (Quudinta Isku-xidhan ee U Dhawaanshaha): Habkani wuxuu adeegsadaa oscillator ama curiye soo-jiidasho ah oo u dhow khadka microstrip si uu calaamadda ugu shubo anteenada. Waxay bixin kartaa isku-dheellitirka impedance-ka oo sarreeya iyo baaxadda soo noqnoqoshada oo ballaaran, waxayna ku habboon tahay naqshadeynta anteenooyinka ballaaran.
4. (Quudinta Isku-xidhka): Habkani wuxuu adeegsadaa fiilooyin isku-xidhka isku-xidhka ama fiilooyinka isku-xidhka isku-xidhka si loogu shubo calaamadaha RF qaybta shucaaca ee anteenada. Habkani wuxuu badanaa bixiyaa is-waafajin wanaagsan oo ka hortag ah iyo hufnaan shucaac, wuxuuna si gaar ah ugu habboon yahay xaaladaha loo baahan yahay isku-xirka anteenada hal mar.
Habab kala duwan oo quudin ah ayaa saameyn doona iswaafajinta is-dhexgalka, astaamaha soo noqnoqda, hufnaanta shucaaca iyo qaab-dhismeedka jireed ee anteenada.
Sida loo doorto barta quudinta ee isku-xidhka ee anteenada microstrip
Marka la naqshadaynayo anteeno microstrip ah, doorashada goobta barta quudinta coaxial waa muhiim si loo hubiyo waxqabadka anteenada. Waa kuwan qaar ka mid ah hababka la soo jeediyay ee lagu dooranayo dhibcaha quudinta coaxial ee anteenooyinka microstrip:
1. Isku-dheelitir: Isku day inaad doorato barta quudinta ee coaxial ee ku taal bartamaha anteenada microstrip si aad u ilaaliso isku-dheelitirnaanta anteenada. Tani waxay gacan ka geysaneysaa hagaajinta hufnaanta shucaaca anteenada iyo isku-dheelitirnaanta iska caabbinta.
2. Meesha uu garoonku koronto ku shaqeeyo ugu weyn yahay: Barta quudinta ee coaxial-ka ayaa ugu fiican in lagu doorto booska uu garoonku koronto ku shaqeeyo ee anteenada microstrip-ka ay ugu weyn tahay, taasoo hagaajin karta waxtarka quudinta oo yarayn karta khasaaraha.
3. Halka uu hadda ugu badan yahay: Barta quudinta ee coaxial waxaa laga dooran karaa meel u dhow meesha uu hadda ku jiro anteenada microstrip-ka ugu badan yahay si loo helo awood shucaac iyo hufnaan sare.
4. Barta goobta korontada ee eber ah ee hal hab: Naqshadeynta anteenada microstrip, haddii aad rabto inaad gaarto shucaac hal hab ah, barta quudinta coaxial waxaa badanaa lagu doortaa barta goobta korontada ee eber ah ee hal hab si loo gaaro isbarbardhigga impedance iyo shucaaca oo wanaagsan.
5. Falanqaynta soo noqnoqoshada iyo qaabka hirarka: Adeegso qalabka jilitaanka si aad u sameyso falanqaynta soo noqnoqoshada iyo qaybinta garoonka/hadda korontada si aad u go'aamiso goobta ugu habboon ee quudinta coaxial.
6. Ka fiirso jihada iftiinka: Haddii loo baahdo astaamaha shucaaca oo leh jiho gaar ah, goobta barta quudinta ee isku-xidhka ah waxaa loo dooran karaa iyadoo loo eegayo jihada iftiinka si loo helo waxqabadka shucaaca anteenada ee la rabo.
Habka naqshadeynta dhabta ah, badanaa waxaa lagama maarmaan ah in la isku daro hababka kor ku xusan oo la go'aamiyo booska ugu wanaagsan ee barta quudinta coaxial iyada oo loo marayo falanqaynta jilitaanka iyo natiijooyinka cabbirka dhabta ah si loo gaaro shuruudaha naqshadeynta iyo tilmaamayaasha waxqabadka ee anteenada microstrip. Isla mar ahaantaana, noocyada kala duwan ee anteenooyinka microstrip (sida anteenooyinka balastarada, anteenooyinka helical, iwm.) waxay yeelan karaan tixgelin gaar ah marka la dooranayo goobta barta quudinta coaxial, kuwaas oo u baahan falanqayn gaar ah iyo hagaajin ku salaysan nooca anteenada gaarka ah iyo xaaladda codsiga.

5. Astaamaha Kala-fogaanshaha:
- Anteenooyinka Microstrip waxaa loogu talagalay kala-soocidda toosan ama kala-soocidda wareegsan, taasoo siinaysa heer dabacsanaan gaar ah.
