Anteenada Vivaldi: Mabda'a Shaqada, Astaamaha iyo Codsiyada

Anteenada Vivaldi, oo sidoo kale loo yaqaan anteeno dalool ah oo wareegsan, waa anteeno jiho ballaaran oo si weyn loogu isticmaalo nidaamyada tijaabinta RF, microwave, radar, dagaalka elektaroonigga ah, cabbirka, iyo nidaamyada tijaabinta wireless-ka. Fureheeda gaarka ah ee wareegsan wuxuu u oggolaanayaa tamarta elektaroonigga ah inay si tartiib tartiib ah uga gudubto qaab-dhismeedka gudbinta ee la hago una gudubto meel bannaan, taasoo ka caawinaysa anteenada inay gaarto hawlgalka ballaaran iyo shucaaca jihada.

Marka la barbardhigo anteenooyin badan oo resonant ah oo lagu habeeyay meel cidhiidhi ah oo soo noqnoqota, anteenooyinka Vivaldi waxay isticmaalaan qaab-dhismeed hirar-socod ah. Tani waxay ka dhigaysaa kuwo si gaar ah u soo jiidasho leh nidaamyada u baahan daboolid soo noqnoqota oo ballaaran oo ay weheliso qaab-dhismeed farsamo oo toosan ama bir ah oo fudud.

Sidee ayuu u shaqeeyaa Vivaldi Antenna?

Anteenada aasaasiga ah ee Vivaldi waxay ka kooban tahay laba gees oo gudbiya oo sameeya god godad ah oo wareegsan. Godku si tartiib tartiib ah ayuu uga fidaa meel cidhiidhi ah oo quudin ah una gudbeysa dalool ballaaran oo shucaac leh.

Marka tamarta RF ay gasho anteenada, hirarka elektromagnetic-ga wuxuu ku socdaa godka qallafsan. Marka ballaca godka uu kordho, hirarka la hago ayaa si tartiib tartiib ah ugu biiraya booska bannaan wuxuuna si weyn ugu faafo dhammaadka furan ee anteenada.

Kala-guurkan tartiib-tartiibka ah waa mid ka mid ah sababaha ugu muhiimsan ee anteenooyinka Vivaldi ay u bixin karaan astaamo ballaaran.

Soo noqnoqoshada yar ee la isticmaali karo waxaa si xooggan u saameeya cabbirka jireed ee daloolka iyo hoos u dhaca, halka waxqabadka soo noqnoqoshada sare uu ku xiran yahay arrimo ay ka mid yihiin kala-guurka quudinta, joomatari hoos u dhaca, cabbirka gudbiyaha, iyo saxnaanta wax soo saarka.

Astaamaha Shucaaca

Anteenada Vivaldi guud ahaan waa anteeno dab-damis ah, taasoo la micno ah in shucaaceeda ugu weyn uu ku wajahan yahay dhammaadka furan ee daloolka qallafsan.

Astaamaha shucaaca waxay ku xiran yihiin dhowr cabbir oo naqshadeed, oo ay ku jiraan:

Ballaca daloolka
Dhererka iyo astaanta
Qaab-dhismeedka quudinta
Soo noqnoqoshada hawlgalka
Joomatari dhulka iyo koontaroolaha
Cabbirrada farsamada

Marka ay soo noqnoqoshadu isbeddesho, gobolka shucaaca ee waxtarka leh ee ku teedsan qaab-dhismeedka qallafsan ayaa sidoo kale isbeddela. Tani waxay u oggolaanaysaa anteenada inay ka shaqeyso meel ballaaran oo soo noqnoqosha ah iyada oo aan lagu tiirsanayn hal resonance cidhiidhi ah.

Anteenooyinka Vivaldi waxaa badanaa loogu talagalay kala-soocidda toosan, in kasta oo waxqabadka kala-soocidda ay ku xiran tahay qaab-dhismeedka gaarka ah iyo habaynta quudinta.

Noocyada ugu Muhiimsan ee Antennas-ka Vivaldi

Qaababyo dhowr ah oo anteeno Vivaldi ah ayaa si caadi ah loogu isticmaalaa injineernimada RF.

Anteenada Vivaldi ee Caadiga ah
Wuxuu adeegsadaa god godad ah oo ka samaysan laba gobol oo gudbiya korontada waana mid ka mid ah hirgelinta ugu badan.

Anteenada Vivaldi ee Antipodal
Wuxuu adeegsadaa walxaha gudbiya ee dhinacyada iska soo horjeeda ee substrate-ka dielectric. Qaabeyntani waxay bixin kartaa kala-guur ku habboon oo ka yimaada quudinta khadadka gudbinta qaarkood una gudubta daloolka shucaaca.

Anteenada Vivaldi ee Dheelitiran ee Antipodal
Wuxuu adeegsadaa qaab-dhismeed lakabyo badan leh oo siman si uu u hagaajiyo dheelitirka goobta iyo sifooyinka kala-soocidda ee codsiyada ballaaran qaarkood.

Qaabab kala duwan ayaa loo dooran karaa iyadoo loo eegayo baaxadda, kala-goynta, habka quudinta, habka wax-soo-saarka, iyo shuruudaha isku-dhafka nidaamka.

Tilmaamaha Muhiimka ah Marka la Xulayo Antenna Vivaldi

Marka aad dooranayso anteenada Vivaldi, tirada soo noqnoqoshadu waa barta bilowga oo keliya.

Gain wuxuu tilmaamayaa sida ugu waxtarka badan ee anteenadu u ururiso shucaaca jihada hore.

VSWR waxay ka tarjumaysaa iswaafajinta is-waafajinta ee u dhaxaysa anteenada iyo nidaamka RF. VSWR-ka hooseeya guud ahaan macnaheedu waa awood aan si fiican u muuqan.

Kala-soocidda waa inay la mid noqotaa nidaamka RF ee bartilmaameedka ah si loo yareeyo is-waafajinta kala-soocidda.

3 dB Beamwidth wuxuu qeexayaa ballaca xagasha ee shucaaca ugu weyn waana muhiim marka la eego radar, kormeerka, iyo codsiyada cabbirka jihada.

Waxqabadka Isdhaafsiga Polarization sidoo kale waa muhiim marka daahirnimada polarization ay muhiim tahay.

Arrimaha farsamada sida nooca isku xirka, cabbirka anteenada, miisaanka, qaab-dhismeedka rakibaadda, iyo maaraynta awoodda waa in sidoo kale la tixgeliyaa inta lagu jiro isku-dhafka nidaamka.

Tusaale ahaan, Antenna-ka Vivaldi ee RF MISO ee RM-VA0212-6 ee Toosan ee Polarized Linear Vivaldi wuxuu ka shaqeeyaa 0.2 ilaa 1.2 GHz, wuxuu bixiyaa faa'iido caadi ah oo ah 6 dBi, wuxuu adeegsadaa polarization toosan iyo interface N-Female ah, waxaana loo cayimay radar, isgaarsiinta dayax-gacmeedka, dagaalka elektaroonigga ah, iyo codsiyada tijaabinta wireless-ka ee heerka sare ah.

Nidaamyada safka, walxo badan oo Vivaldi ah ayaa sidoo kale loo habeyn karaa si loo helo faa'iido sare, alwaaxyo cidhiidhi ah, ama awood xakameyn elektaroonig ah.

Gunaanad

Anteenada Vivaldi waxay isku daraysaa qaab-dhismeedka hirarka safarka ee godad-ka-godan, hawlgalka ballaaran, iyo shucaaca jihada, taasoo ka dhigaysa qaab-dhismeedka anteenada ee la jaan qaadi kara nidaamyada casriga ah ee RF iyo microwave-ka.

Waxqabadkeeda dhabta ah wuxuu ku xiran yahay qaab-dhismeedka jajaban, cabbirka daloolka, naqshadeynta quudinta, soo noqnoqoshada hawlgalka, iyo hirgelinta farsamada. Sidaa darteed injineeradu waa inay qiimeeyaan oo keliya baaxadda iyo faa'iidada, laakiin sidoo kale VSWR, polarization, beamwidth, waxqabadka polarization-ka iskutallaabta, interface RF, iyo shuruudaha rakibidda marka la dooranayo qaab ku habboon.

Antenna-yada Vivaldi waxay bixiyaan xal dabacsan oo daboolaya soo noqnoqoshada ballaaran iyo waxqabadka RF ee jihada labaduba waa muhiim.
