ʻO kahi antenna Cassegrain he antenna ʻelua-reflector maikaʻi loa, nona ka inoa a me ka hoʻolālā i loaʻa mai ka telescope Cassegrain. Loaʻa iā ia kahi mea hoʻohālike mua (kahi paraboloid) a me kahi mea hoʻohālike kiʻekiʻe (kahi hyperboloid), i hoʻonoho ʻia ma luna o ke kiko kiko o ka reflector mua.

ʻO kāna kumu hana penei: hoʻomālamalama mua ka pū hānai i nā hawewe electromagnetic i ka mea hoʻomālamalama lua, a laila e hōʻike i nā nalu ma luna o ka reflector mua. Hoʻopili ka mea hoʻomaʻamaʻa mua i kēia mau nalu i kahi kukuna ʻōlike me ke kuhikuhi nui no ka lawe ʻana. Hiki i kēia ala 'opelika "pilikia" ke kau ʻia ka hānai ma hope o ka reflector mua, e hōʻemi nui ana i ka nalowale o ka feedline a me ka maʻalahi o ka mālama ʻana.

ʻO nā pōmaikaʻi nui o kēia antenna, ʻo ia ka loaʻa kiʻekiʻe, nā lobes ʻaoʻao haʻahaʻa, ka hoʻolālā paʻa (i hoʻohālikelike ʻia me kahi parabola lōʻihi-focal-lōʻihi), a me ke kau ʻana o ka meaʻai a me nā mea hoʻokipa ma hope o ka reflector mua, e hōʻemi ana i ka nalowale o ka lawe ʻana. ʻO kona hemahema nui, ʻo ia ka hoʻopaʻa ʻia ʻana o ka ʻāpana o ka lāʻau nui e ka mea hoʻonaninani kiʻekiʻe a me kona ʻano kākoʻo. Hoʻohana nui ʻia ia i nā kamaʻilio satellite, radio astronomy, a me nā ʻōnaehana radar lōʻihi.
