I-antenna yeCassegrain yi-antenna esebenza kakuhle kakhulu ene-dual-reflector, egama layo kunye noyilo lwayo luvela kwi-telescope yeCassegrain. Iqulathe i-reflector ephambili (i-paraboloid) kunye ne-reflector yesibini (i-hyperboloid), ebekwe ngaphezulu kwendawo ephambili ye-reflector ephambili.

Umgaqo wayo wokusebenza ngolu hlobo lulandelayo: uphondo lokutya luqala ngokusasaza amaza e-electromagnetic ukuya kwi-reflector yesibini, ethi emva koko ibonise amaza kwi-reflector ephambili. I-reflector ephambili idibanisa la maza ibe ngumqadi ohambelanayo, ojolise kakhulu ekudluliseleni. Le ndlela "egobileyo" ye-optical ivumela i-feed ukuba ifakwe ngasemva kwe-reflector ephambili, nto leyo enciphisa kakhulu ilahleko ye-feedline kwaye yenza kube lula ukugcinwa.

Iingenelo eziphambili zale antenna kukufumana kwayo okuphezulu, ii-lobes ezisecaleni ezisezantsi, isakhiwo esincinci (xa kuthelekiswa neparabola ende), kunye nokubekwa kwe-feed kunye nee-receiver ngasemva kwe-reflector ephambili, nto leyo enciphisa ukulahleka kothumelo. Ingxaki yayo ephambili kukuvaleka kwenxalenye ye-main beam yi-reflector yesibini kunye nesakhiwo sayo sokuxhasa. Isetyenziswa kakhulu kunxibelelwano lwesathelayithi, i-radio astronomy, kunye neenkqubo ze-radar ezikude.
