Yini izibani zenkungu? Umehluko phakathi kwamalambu wenkungu ngaphambili nangemuva?
Izibani zenkungu ziyehluka ngezibani ezisebenzayo ngesakhiwo sangaphakathi nesikhundla esinqunyelwe kusengaphambili. Izibani zenkungu zivame ukubekwa phansi kwemoto, esondele kakhulu emgwaqweni. Izibani zenkungu zine-beam cutoff angle phezulu kwezindlu futhi zenzelwe kuphela ukukhanyisa umhlabathi phambi noma ngemuva kwezimoto ezisendleleni. Enye into evamile ilensi ephuzi, isibani esikhanyayo esiphuzi, noma sobabili. Abanye abashayeli bacabanga ukuthi wonke amalambu enkungu aphuzi, umyalo ophuzi we-wavelength; Ukukhanya okuphuzi kune-wavelength ende, ngakho-ke kungangena endaweni enkulu. Umqondo wawungukuthi ukukhanya okuphuzi kungadlula kwizinhlayiya zenkungu, kepha ayikho idatha yesayensi ekhonkolo yokuhlola umbono. Izibani zenkungu zisebenza ngenxa yesikhundla esikhuphukayo kanye nokuhlose kwe-angle, hhayi umbala.
