Antena ya Cassegrain ndi antenna yowala bwino kwambiri yokhala ndi ma reflector awiri, yomwe dzina lake ndi kapangidwe kake zimachokera ku telescope ya Cassegrain. Ili ndi chowunikira chachikulu (paraboloid) ndi chowunikira chachiwiri (hyperboloid), chomwe chili pamwamba pa malo owunikira oyamba.

Mfundo yake yogwirira ntchito ndi iyi: poyamba nyanga yamagetsi imatulutsa mafunde amagetsi kupita ku chowunikira chachiwiri, chomwe kenako chimawonetsa mafundewo kupita ku chowunikira chachikulu. Chowunikira chachikulu chimasonkhanitsa mafunde awa kukhala nyali yofanana, yolunjika kwambiri kuti iperekedwe. Njira "yopindika" iyi yowunikira imalola kuti chakudyacho chiyikidwe kumbuyo kwa chowunikira chachikulu, zomwe zimachepetsa kwambiri kutayika kwa mzere wamagetsi ndikuchepetsa kukonza.

Ubwino waukulu wa antenna iyi ndi kuchuluka kwake kwakukulu, malo otsika a mbali, kapangidwe kakang'ono (poyerekeza ndi parabola yayitali), komanso malo odyetsera ndi olandirira kumbuyo kwa chowunikira chachikulu, zomwe zimachepetsa kutayika kwa ma transmission. Vuto lake lalikulu ndi kutsekeka kwa gawo la kuwala kwakukulu ndi chowunikira chachiwiri ndi kapangidwe kake kothandizira. Chimagwiritsidwa ntchito kwambiri pakulankhulana ndi satellite, zakuthambo za wailesi, ndi machitidwe a radar akutali.
