I-antenna ye-Cassegrain iyi-antenna esebenza kahle kakhulu ene-dual-reflector, egama layo kanye nomklamo wayo kususelwa ku-Cassegrain telescope. Yakhiwa yi-reflector eyinhloko (i-paraboloid) kanye ne-reflector yesibili (i-hyperboloid), ebekwe ngaphezu kwendawo egxile kuyo ye-reflector eyinhloko.

Isimiso salo sokusebenza simi kanje: uphondo lokuphakelayo luqala ngokukhipha amaza kagesi lubhekise ku-reflector yesibili, bese luveza amaza lubhekise ku-reflector eyinhloko. I-reflector eyinhloko ihlanganisa lawa maza abe yi-beam efanayo, eqondisa kakhulu ukudluliselwa. Le ndlela "egoqiwe" ye-optical ivumela i-feed ukuthi ifakwe ngemuva kwe-reflector eyinhloko, okunciphisa kakhulu ukulahlekelwa kwe-feedline futhi kube lula ukugcinwa.

Izinzuzo ezibalulekile zale antenna ukuzuza kwayo okuphezulu, ama-lobes aphansi ohlangothini, isakhiwo esincane (uma kuqhathaniswa ne-parabola ende-focal-length), kanye nokubekwa kwe-feed kanye nama-receiver ngemuva kwe-reflector eyinhloko, okunciphisa ukulahleka kokudlulisela. Inkinga yayo enkulu ukuvinjelwa kwengxenye yomsebe oyinhloko yi-reflector yesibili kanye nesakhiwo sayo sokusekela. Isetshenziswa kabanzi kwezokuxhumana ngesathelayithi, i-radio astronomy, kanye nezinhlelo ze-radar ezikude.
