Qaab dhismeedka aanteenada microstripguud ahaan waxa uu ka kooban yahay substrate dielectric, radiator iyo saxan dhulka ah. Dhumucda substrate-ka dielectric ayaa aad uga yar hirarka dhererka. Lakabka birta khafiifka ah ee hoose ee substrate-ka ayaa ku xiran saxanka dhulka. Dhinaca hore, lakabka birta ah ee khafiifka ah oo leh qaab gaar ah ayaa lagu sameeyaa habka sawir-qaadista sida hiitarka. Qaabka saxanka shucaaca ah waxaa loo bedeli karaa siyaabo badan iyadoo loo eegayo shuruudaha.
Kor u kaca ee tignoolajiyada isdhexgalka microwave iyo hababka cusub ee wax soo saarka ayaa kor u qaaday horumarinta anteenooyinka microstrip. Marka la barbar dhigo anteenooyinka dhaqanka, anteenooyinkooda microstrip ma aha oo kaliya mid yar oo cabbir ah, miisaankoodu yar yahay, muuqaalkiisu hooseeyo, si sahlan loo waafajiyo, fududahay in la isku daro, kharash yar, oo ku habboon wax soo saarka ballaaran, laakiin sidoo kale waxay leeyihiin faa'iidooyinka guryaha korantada ee kala duwan.
Afarta hab ee quudinta aasaasiga ah ee anteenooyinka microstrip waa sida soo socota:
1. (Microstrip Feed): Tani waa mid ka mid ah hababka quudinta ugu badan ee anteenooyinka microstrip. Calaamadda RF waxaa lagu kala qaadaa qaybta shucaaca ee anteenada iyada oo loo marayo xariiqda microstrip, badanaa iyada oo loo marayo isku xirka khadka microstrip iyo balastarka shucaaca. Habkani waa mid fudud oo dabacsan oo ku habboon naqshadeynta anteenooyinkooda microstrip badan.
2. (Aperture-lammaantay Feed): Habkani waxa uu isticmaalaa boosaska ama godadka on saxan saldhig anteeno microstrip quudin line microstrip galay element radiating of anteenada. Habkani wuxuu ku siin karaa isbarbardhig ka wanaagsan oo waxtarka shucaaca, wuxuuna sidoo kale yarayn karaa ballaca laydhka toosan iyo midka toosan ee lobes-ka.
3. (Proximity Coupled Feed): Habkani waxa uu isticmaalaa oscillator ama element inductive u dhow line microstrip in ay ku quudiyaan signalka anteenada. Waxay ku siin kartaa isbarbardhigga sare ee isbarbardhigga iyo band soo noqnoqoshada ballaaran, waxayna ku habboon tahay naqshadeynta anteenooyinkooda ballaaran.
4. (Coaxial Feed): Habkani waxa uu isticmaalaa fiilooyinka coplanar ama fiilooyinka coaxial si loo quudiyo calaamadaha RF ee qaybta shucaaca ee anteenada. Habkani wuxuu inta badan bixiyaa is-waafajinta wanaagsan iyo hufnaanta shucaaca, wuxuuna si gaar ah ugu habboon yahay xaaladaha halka loo baahan yahay interface hal anteeno ah.
Hababka quudinta ee kala duwan waxay saamayn doonaan is-waafajinta is-waafajinta, sifooyinka soo noqnoqda, hufnaanta shucaaca iyo qaabka jireed ee anteenada.
Sida loo doorto barta quudinta coaxial ee anteenada microstrip
Marka la naqshadeynayo anteenada microstrip, doorashada meesha ay ku taal barta quudinta coaxial ayaa muhiim u ah xaqiijinta waxqabadka anteenada. Waa kuwan qaar ka mid ah hababka la soo jeediyay ee xulashada dhibcaha quudinta coaxial ee anteenooyinka microstrip:
1. Summetry: Isku day in aad doorato barta quudinta coaxial ee xarunta anteenada microstrip si aad u ilaaliso summaynta anteenada. Tani waxay gacan ka geysaneysaa hagaajinta waxtarka shucaaca anteenada iyo is-waafajinta is-waafajinta.
2. Meesha korantadu ay tahay tan ugu weyn: Goobta quudinta coaxial ayaa si fiican loo doortaa booska korantada ee anteenada microstrip ugu weyn, taas oo wanaajin karta hufnaanta quudinta waxayna yareyn kartaa khasaaraha.
3. Halkee hadda waa ugu badnaan: dhibic feed coaxial la dooran karaa meel u dhow meesha hadda ee anteenada microstrip waa ugu badnaan si aad u hesho awoodda shucaaca sare iyo hufnaan.
4. Zero barta korantada ee hal hab: In design anteeno microstrip, haddii aad rabto in aad gaadho shucaaca hab hal, dhibic feed coaxial waxaa sida caadiga ah loo doortay at eber beerta korantada in hab hal si loo gaaro si fiican u dhigma impedance iyo shucaaca. sifo.
5. Falanqaynta soo noqnoqda iyo mawjada: Isticmaal qalabka jilitaanka si aad u sameyso xaaqid joogta ah iyo goob koronto / falanqaynta qaybinta hadda si loo go'aamiyo goobta ugu fiican ee quudinta coaxial.
6. Tixgeli jihada iftiinka: Haddii sifooyinka shucaaca ee leh jihooyin gaar ah loo baahan yahay, meesha ay ku taal barta quudinta coaxial waxaa loo dooran karaa iyadoo loo eegayo jihada iftiinka si loo helo waxqabadka shucaaca anteenada ee la doonayo.
Habka naqshadeynta dhabta ah, sida caadiga ah waa lagama maarmaan in la isku daro hababka kor ku xusan iyo go'aaminta booska quudinta coaxial ugu fiican iyada oo loo marayo falanqaynta jilitaanka iyo natiijooyinka cabbirka dhabta ah si loo gaaro shuruudaha naqshadeynta iyo tilmaamayaasha waxqabadka anteenada microstrip. Isla mar ahaantaana, noocyada kala duwan ee anteenooyinkooda microstrip (sida anteenooyinkooda balastar, anteenooyinka helical, iwm) waxaa laga yaabaa in qaar ka mid ah tixgelin gaar ah marka la dooranayo meesha dhibic feed coaxial, taas oo u baahan falanqayn gaar ah iyo hagaajinta ku salaysan nooca antenna gaar ah iyo. dhacdo codsiga. .
Farqiga u dhexeeya anteenada microstrip iyo anteenada balastar
Anteenada Microstrip iyo anteenada balastar waa laba anteeno yaryar oo caadi ah. Waxay leeyihiin qaar ka mid ah farqi iyo astaamo:
1. Qaab dhismeedka iyo qaabaynta:
- Anteenada microstrip sida caadiga ah waxay ka kooban tahay balastar microstrip iyo saxan dhulka ah. balastar microstrip waxay u adeegtaa sidii curiye shucaac ah waxayna ku xidhan tahay saxanka dhulka iyada oo loo marayo khadka microstrip.
- Anteenooyinka balastar guud ahaan waa balastar kaari in si toos ah ku xardhan on substrate dielectric ah oo aan u baahnayn khadadka microstrip sida anteenooyinka microstrip.
2. Cabbirka iyo qaabka:
- Anteenooyinkooda Microstrip waa kuwo aad u yar oo cabbir ah, oo inta badan loo isticmaalo xargaha soo noqnoqda ee microwave, waxayna leeyihiin naqshad dabacsan.
- Anteenooyinkooda balastar sidoo kale waxaa loo qaabayn karaa in la yareeyo, xaaladaha qaarkoodna, cabbirkoodu wuu yaraan karaa.
3. Xadka soo noqnoqda:
- Inta jeer ee anteenooyinka microstrip waxay u dhaxayn kartaa boqolaal megahertz ilaa dhowr gigahertz, oo leh astaamo ballaadhan oo gaar ah.
- Anteenooyinka balastar-ku waxay inta badan leeyihiin hawl-qabad ka wanaagsan qaybaha soo noqnoqda ee gaarka ah waxaana guud ahaan loo adeegsadaa codsiyada soo noqnoqda ee gaarka ah.
4. Habka wax soo saarka:
- Anteenooyinka Microstrip waxaa inta badan lagu sameeyaa iyadoo la isticmaalayo tignoolajiyada looxa wareegga daabacan, kaas oo la soo saari karo tiro badan oo leh qiimo jaban.
- Anteenooyinka balaastikada ah waxaa badanaa laga sameeyaa walxo silikoon ku saleysan ama walxo kale oo gaar ah, waxay leeyihiin shuruudo farsameed oo gaar ah, waxayna ku habboon yihiin wax soo saarka dufcadaha yar yar.
5. Sifooyinka kala soocida:
- Anteenooyinkooda Microstrip waxaa loo qaabayn karaa polarization linear ama polarization wareeg ah, iyaga oo siinaya heer ka mid ah dabacsanaanta.
- Astaamaha polarization-ka ee anteenooyinka balastar-ku waxay inta badan ku xidhan yihiin qaab-dhismeedka iyo qaab-dhismeedka anteenada mana aha kuwo u dabacsan sida anteenooyinka microstrip.
Guud ahaan, anteenooyinka microstrip iyo anteenooyinka balastar waxay ku kala duwan yihiin qaab dhismeedka, kala duwanaanshaha soo noqnoqda, iyo habka wax soo saarka. Doorashada nooca anteenada ku habboon waxay u baahan tahay in lagu saleeyo shuruudaha codsiga gaarka ah iyo tixgelinta naqshadeynta.
