Antenna pepeiaohaoʻO ia ka antenna ʻili, he antenna microwave me kahi ʻāpana keʻa poepoe a ʻehā paha kahi e wehe mālie ai ke kikowaena o ke alakaʻi nalu. ʻO ia ke ʻano antenna microwave i hoʻohana nui ʻia. Hoʻoholo ʻia kona kahua radiation e ka nui o ka waha a me ke ʻano hoʻolaha o ka mea ʻōlelo. I waena o lākou, hiki ke helu ʻia ka mana o ka paia pepeiaohao ma ka radiation me ka hoʻohana ʻana i ke kumumanaʻo o ka diffraction geometric. Inā ʻaʻole loli ka lōʻihi o ka pepeiaohao, e hoʻonui ʻia ka nui o ka ʻili waha a me ka ʻokoʻa pae quadratic i ka piʻi ʻana o ke kihi wehe pepeiaohao, akā ʻaʻole e loli ka loaʻa me ka nui o ka ʻili waha. Inā pono ʻoe e hoʻonui i ke alapine (frequency band) o ka mea ʻōlelo, pono ʻoe e hoʻemi i ka noʻonoʻo ʻana ma ka ʻāʻī a me ka waha o ka mea ʻōlelo; e emi ana ka noʻonoʻo ʻana i ka piʻi ʻana o ka nui o ka waha. He maʻalahi ke ʻano o ka antenna pepeiaohao, a he maʻalahi a maʻalahi hoʻi ke kaohi i ke ʻano. Hoʻohana pinepine ʻia ia ma ke ʻano he antenna kuhikuhi waena. Hoʻohana pinepine ʻia nā antenna pepeiaohao reflector parabolic me ka laulā alapine ākea, nā lobes ʻaoʻao haʻahaʻa a me ka pono kiʻekiʻe i nā kamaʻilio relay microwave.
Hiki ke helu ʻia ke kahua radiation o ka antenna pepeiaohao mai ke kahua ʻili me ka hoʻohana ʻana i ke kumumanaʻo o Huygens. Hoʻoholo ʻia ke kahua ʻili waha e ka nui o ka ʻili waha a me ke ʻano nalu hoʻolaha o ka pepeiaohao. Hiki ke hoʻohana ʻia ke kumumanaʻo diffraction geometric e helu i ka mana o ka paia pepeiaohao ma ka radiation, i hiki ai ke kūlike ke ʻano i helu ʻia a me ka waiwai i ana ʻia a hiki i ka lobe ʻaoʻao mamao. Hoʻoholo ʻia kona mau ʻano radiation e ka nui a me ka hoʻolaha ʻana o ke kahua o ka ʻili waha, ʻoiai ua hoʻoholo ʻia ka impedance e ka noʻonoʻo ʻana o ka ʻāʻī o ka mea ʻōlelo (ka discontinuity hoʻomaka) a me ka ʻili waha. Ke paʻa ka lōʻihi o ka pepeiaohao, inā e hoʻonui mālie ʻia ke kihi wehe o ka pepeiaohao, e hoʻonui pū ʻia ka nui o ka ʻili waha a me ka ʻokoʻa pae quadratic i ka manawa like, akā ʻaʻole e hoʻonui ʻia ka loaʻa i ka manawa like me ka nui o ka ʻili waha, a aia kahi loaʻa me ka waiwai nui loa. ʻO ka nui o ka ʻili waha, ʻo ka mea ʻōlelo me kēia nui ua kapa ʻia ʻo ia ka mea ʻōlelo maikaʻi loa. Hoʻolaha nā pepeiaohao conical a me nā pepeiaohao pyramidal i nā nalu spherical, ʻoiai nā pepeiaohao ʻano peʻahi e wehe ana ma kekahi ʻili (ʻili E a i ʻole H) e hoʻolaha i nā nalu cylindrical. ʻO ke kahua ʻili o ka waha pepeiaohao he kahua me ka ʻokoʻa pae quadratic. Pili ka nui o ka ʻokoʻa pae quadratic i ka lōʻihi o ka pepeiaohao a me ka nui o ka ʻili o ka waha.
Hoʻohana pinepine ʻia nā antenna pepeiaohao ma nā wahi aʻe: 1. Nā hānai no nā telescope lekiō nui, nā hānai antenna noʻonoʻo no nā kikowaena honua ukali, a me nā hānai antenna noʻonoʻo no nā kamaʻilio hoʻoili microwave; 2. Nā antenna unit no nā phased arrays; 3. Nā Antenna I nā ana, hoʻohana pinepine ʻia nā antenna pepeiaohao ma ke ʻano he kūlana maʻamau no ka calibration a me ka hoʻāʻo ʻana i ka loaʻa o nā antenna loaʻa kiʻekiʻe ʻē aʻe.
