Kala-fogaanshaha Anteenada: Waa maxay Kala-fogaanshaha Anteenada iyo Sababta ay Muhiim u tahay
Injineerada elektaroonigga ah waxay ogyihiin in anteenooyinku ay diraan oo ay helaan calaamadaha qaabka hirarka tamarta elektromagnetic (EM) ee lagu sharraxay isla'egyada Maxwell. Sida mowduucyo badan, isla'egyadan, iyo faafinta, sifooyinka electromagnetism, waxaa lagu baran karaa l...Akhriso wax dheeraad ah -
Mabda'a shaqada iyo adeegsiga anteenada geeska
Taariikhda anteenooyinka geeska waxay dib ugu noqotaa 1897, markii cilmi-baare raadiye Jagadish Chandra Bose uu sameeyay naqshado tijaabo ah oo hormuud ah isagoo adeegsanaya microwaves. Markii dambe, GC Southworth iyo Wilmer Barrow waxay alifeen qaab-dhismeedka anteenada geeska casriga ah 1938 siday u kala horreeyaan. Tan iyo...Akhriso wax dheeraad ah -
Waa maxay anteenada geeska? Waa maxay mabaadi'da ugu muhiimsan iyo isticmaalka?
Anteenada geeska waa anteeno dusha sare ah, anteeno microwave ah oo leh isgoys wareegsan ama qaab dhismeed leh oo terminalka hagaha hirarka uu si tartiib tartiib ah u furmo. Waa nooca anteenada microwave-ka ee ugu isticmaalka badan. Goobteeda shucaaca waxaa lagu go'aamiyaa cabbirka afka iyo dabinnada...Akhriso wax dheeraad ah -
Ma taqaanaa farqiga u dhexeeya hagaha mowjadaha jilicsan iyo hagaha mowjadaha adag?
Hagaha hirarka jilicsan waa khad gudbin ah oo u adeega sidii kayd u dhexeeya qalabka microwave-ka iyo quudiyeyaasha. Darbiga gudaha ee hagaha hirarka jilicsan wuxuu leeyahay qaab-dhismeed tolmo leh, kaas oo aad u dabacsan oo u adkeysan kara foorarsiga adag, fidinta iyo cadaadiska. Sidaa darteed, waa ...Akhriso wax dheeraad ah -
Anteenooyinka Caadiga ah ee la Isticmaalo | Hordhac ku saabsan lix nooc oo anteenooyin gees ah oo kala duwan
Anteenada geeska waa mid ka mid ah anteenooyinka si weyn loo isticmaalo oo leh qaab-dhismeed fudud, baaxad ballaaran oo soo noqnoqosho ah, awood koronto oo weyn iyo faa'iido sare. Anteenooyinka geeska waxaa badanaa loo isticmaalaa anteenooyin quudin ah oo ku jira xiddigiska raadiyaha ee baaxadda weyn, raadraaca dayax-gacmeedka, iyo anteenooyinka isgaarsiinta. Intaa waxaa dheer, s...Akhriso wax dheeraad ah -
