Anteenooyinka laba-geesoodka ah waxaa si weyn loogu isticmaalaa tijaabinta iyo cabbiraadda RF halkaas oo waxqabadka ballaaran, daboolida azimuth-ka ballaaran, iyo is-dhexgalka nidaamka dabacsan ay muhiim yihiin. Iyada oo moodooyinka loogu talagalay codsiyada laga bilaabo soo noqnoqoshada RF ee hoose ilaa microwave-ka, hirarka millimeter-ka, iyo xargaha sub-THz ee la xushay,Taxanaha Anteenada Biconical ee RF MISOWaxay siisaa injineerada fursado ballaaran oo loogu talagalay soo noqnoqoshada kala duwan, kala-soocidda, iyo shuruudaha is-dhexgalka.
Halkii ay ku tiirsanaan lahayd hal anteeno si ay u daboosho dhammaan muuqaalka, taxanaha RF MISO wuxuu ka kooban yahay noocyo badan oo daboolayaxargaha soo noqnoqda ee la xushay laga bilaabo 0.02 GHz ilaa 303 GHzTani waxay siinaysaa injineerada dabacsanaan ay ku doortaan anteeno iyadoo loo eegayo heerka shaqada iyo jawiga cabbirka dhabta ah.
Daboolida Balaadhinta ee Codsiyada RF ee Kala Duwan
Kala duwanaanshaha soo noqnoqoshada badanaa waa tixgelinta koowaad marka la dooranayo anteeno laba-geesood ah. Taxanaha RF MISO waxaa ka mid ah moodooyinka daboolaya noocyo kala duwan oo hawlgal ah, laga bilaabo nidaamyada ballaaran ee soo noqnoqda hooseeya ilaa codsiyada millimitir-mawjad sare iyo codsiyada THz-ka hooseeya.
Tusaale ahaan,RM-BCA0023-2wuxuu ka shaqeeyaa laga bilaabo0.02 ilaa 3 GHz, halka moodooyinka sidaRM-BCA120-2iyoRM-BCA245-3u fidi hawlgalka ilaa20 GHziyo45 GHz, siday u kala horreeyaan.
Codsiyada soo noqnoqda sare leh,RM-BCA10110-4 daboolida10 ilaa 110 GHz, halkaRM-BCA300-3waxaa loogu talagalay in laga shaqeeyo laga bilaabo297 ilaa 303 GHz.
Xulashada moodeelka ballaaran waxay u oggolaanaysaa injineerada inay doortaan baaxad soo noqnoqota oo la jaanqaadaysa cabbirka bartilmaameedka ama nidaamka RF halkii ay wax u dhimi lahaayeen waxqabadka anteeno aan ku habboonayn.
Daboolida Azimuth Ballaaran
Astaamo muhiim ah oo ka mid ah qoyska anteenooyinka biconical-ka ah ee RF MISO waa daboolida ballaaran ee azimuth.
Iyada oo ku xidhan qaabka, anteenooyinkani waxay ku habboon yihiin nidaamyada RF halkaas oo calaamadaha loo baahan yahay in la gudbiyo ama laga helo meel ballaaran oo toosan. Tani waxay ka dhigaysaa taxanaha mid waxtar u leh la socodka calaamadaha ballaaran, la socodka, helitaanka jihada, sahaminta, iyo deegaanno kala duwan oo cabbiraadda RF ah.
Shaybaarrada anteenada, anteenooyinka laba-geesoodka ah ayaa sidoo kale loo isticmaali karaa isbarbardhigga faa'iidada, cabbirka qaabka shucaaca, iyo xaqiijinta qolka.
Qaabeynta Kala-fogaanshaha Badan
Nidaamyada RF ee kala duwan waxay u baahan karaan astaamo kala duwan oo kala-soocid ah.
Taxanaha Anteenada Biconical ee RF MISO waxaa ku jira noocyo lehKala-qaybsanaanta toosan ee toosan, Kala-goyn toosan oo 45° ah, Kala-soocidda toosan ee caadiga ah, iyo habaynno wareegsan oo la soo xulay.
Tusaale ahaan, dhowr nooc oo waaweyn ayaa isticmaala kala-soocidda toosan ama 45°, halkaRM-BCA3537-3, oo ka shaqeynaya35 ilaa 37 GHz, waxay bixisaa qaabeyn laba-wareeg ah oo polarization ah.
Kala duwanaanshahan ikhtiyaarrada kala-soocidda waxay siinaysaa injineerada dabacsanaan badan marka ay anteenada ku habboon yihiin shuruudaha kala-soocidda ee nidaamka RF ee ku xeeran.
Is-dhexgalka RF ee dabacsan
Isdhexgalka nidaamku wuxuu noqonayaa mid aad muhiim u ah marka soo noqnoqoshada hawlgalku korodho.
Taxanaha oo dhan, RF MISO waxay bixisaa noocyo kala duwan oo is-dhexgal ah oo isku-dhafan iyo kuwa hagaha hirarka, oo ay ku jiraan:
- Dheddig SMA
- N Dheddig
- 2.92 mm Dheddig
- 2.4 mm Dheddig
- 1.0 mm Dheddig
- Is-dhexgalka hagaha hirarka ee la xushay
Dhammaadka sare ee taxanaha,RM-BCA300-3wuxuu adeegsadaa aHagaha hirarka WR3 oo leh flange UG-387 ah, iyadoo bixinaysa is-dhexgal ku habboon baaxaddeeda hawlgalka 297–303 GHz.
Helitaanka isku-xidhka RF ee kala duwan waxay ka caawisaa injineerada inay anteenada ku daraan qalabka tijaabada, cidhifyada hore ee RF, qalabka cabbirka, iyo qaybaha kale ee nidaamka.
Loogu talagalay Tijaabada iyo Cabbiraadda RF
Anteenooyinka laba-geesoodka ah waxay ciyaari karaan doorar kala duwan iyadoo ku xiran heerka soo noqnoqoshada iyo habaynta nidaamka.
Codsiyada caadiga ah ee Taxanaha Anteenada Biconical ee RF MISO waxaa ka mid ah tijaabinta EMC, oo ay ku jiraan qiiqa shucaaca iyo cabbiraadaha difaaca jirka ee shucaaca; cabbirka anteenada iyo isbarbardhigga faa'iidada; cabbirka qaabka shucaaca iyo xaqiijinta qolka; la socodka calaamadaha ballaaran; la socodka iyo helitaanka jihada; nidaamyada sahanka; iyo goobaha RF ee lagu rakibay, dhulka lagu rakibay, iyo kuwa isku dhafan.
Maadaama taxanaha uu ka kooban yahay isku-darka kala duwan ee faa'iidada, VSWR, polarization, interface RF, cabbirka, iyo habaynta farsamada, xulashada anteenada waa inay had iyo jeer ka bilaabataa baaxadda soo noqnoqoshada bartilmaameedka ka dibna tixgeli shuruudaha nidaamka RF ee dhammaystiran.
Xulashada Anteenada Biconical-ka ee Saxda ah
Marka la dooranayo moodeel, injineeradu waa inay marka hore go'aamiyaan inta jeer ee loo baahan yahay ee hawlgalka, ka dibna waxay qiimeeyaan kala-soocidda iyo shuruudaha is-dhexgalka RF.
Xuduudaha kale sidaVSWR, korodhka, cabbirrada jireed, miisaanka, iyo maaraynta awooddasidoo kale waa in loo tixgeliyaa iyadoo loo eegayo codsiga bartilmaameedka ah.
Tusaale ahaan, moodooyinka soo noqnoqda ee hooseeya waxay yeelan karaan cabbirro farsamo oo aad u weyn, halka moodooyinka millimitir-hirarka iyo kuwa hoose ee THz ay noqon karaan kuwo aad u yar. Shuruudaha is-dhexgalka ayaa sidoo kale isbeddela marka soo noqnoqoshada hawlgalka ay korodho, laga bilaabo isku-xirayaasha caadiga ah ee coaxial ilaa is-dhexgalka millimitir-hirarka gaarka ah.
Taageerada farsamada ee RF MISO waxay ka caawin kartaa macaamiisha dib u eegista baaxadda soo noqnoqoshada, is-dhexgalka RF, kala-goynta, rakibidda, iyo shuruudaha isku-dhafka nidaamka marka la dooranayo anteeno laba-geesood ah oo ku habboon.
Faylalka Anteenada Biconical-ka ah ee Ballaaran laga bilaabo RF ilaa Sub-THz
Laga bilaaboMoodooyinka ballaaran ee 0.02–3 GHz to Naqshadaha sub-THz ee 297–303 GHz, Taxanaha Anteenada Biconical ee RF MISO wuxuu bixiyaa xulashooyin kala duwan oo anteenooyin ah oo loogu talagalay injineernimada RF, cabbiraadda, la socodka, iyo codsiyada isku-dhafka nidaamka.
Iyada oo leh noocyo badan oo soo noqnoqosho ah, habayn kala-soocid ah, cabbirro farsamo, iyo is-dhexgalka RF oo la heli karo, taxanegu wuxuu siinayaa injineerada dabacsanaan ay ku doortaan anteeno iyadoo loo eegayo shuruudaha dhabta ah ee jawiga tijaabada ama madal RF.
Wixii macluumaad dheeraad ah oo ku saabsan qaabka ama caawimaad ku saabsan xulashada anteenada, la xiriir kooxda RF MISO si aad u hesho taageero farsamo.
