Ma ke kahua o ka ʻenekinia microwave, ʻo ka hana antenna kahi mea koʻikoʻi i ka hoʻoholo ʻana i ka pono a me ka pono o nā ʻōnaehana kamaʻilio uea ʻole. ʻO kekahi o nā kumuhana i hoʻopaʻapaʻa nui ʻia, ʻo ia ka mea inā ʻo ka loaʻa kiʻekiʻe ke ʻano o ka antenna maikaʻi aʻe. No ka pane ʻana i kēia nīnau, pono mākou e noʻonoʻo i nā ʻano like ʻole o ka hoʻolālā antenna, me nā ʻano **Microwave Antenna**, **Antenna Bandwidth**, a me ka hoʻohālikelike ʻana ma waena o nā ʻenehana **AESA (Active Electronically Scanned Array)** a me **PESA (Passive Electronically Scanned Array)**. Eia kekahi, e nānā mākou i ke kuleana o kahi **1.70-2.60ʻO GHz Standard Gain Horn Antenna** i ka hoʻomaopopo ʻana i ka loaʻa a me kona mau hopena.
Ke hoʻomaopopo nei i ka loaʻa ʻana o ka Antenna
ʻO ka loaʻa ʻana o ka antenna kahi ana o ke ʻano o ka hoʻokele ʻana a i ʻole ka hoʻopili ʻana o ka ikehu alapine lekiō (RF) i kahi kuhikuhi kikoʻī. Hōʻike pinepine ʻia ia ma nā decibels (dB) a he hana ia o ke ʻano radiation o ka antenna. ʻO kahi antenna loaʻa kiʻekiʻe, e like me ka **Antenna Pepeiao Loaʻa Maʻamau** e hana ana ma ka pae **1.70-2.60 GHz**, e hoʻopili ana i ka ikehu i loko o kahi kukuna haiki, hiki ke hoʻomaikaʻi nui i ka ikaika hōʻailona a me ka laulā kamaʻilio ma kahi kuhikuhi kikoʻī. Eia naʻe, ʻaʻole kēia manaʻo he ʻoi aku ka maikaʻi o ka loaʻa kiʻekiʻe.

Ke Kūlana o ka Antenna Bandwidth
ʻO ka **Antenna Bandwidth** e pili ana i ka laulā o nā alapine (frequencies) e hiki ai i kahi antenna ke hana pono. Hiki i kahi antenna loaʻa kiʻekiʻe ke loaʻa kahi bandwidth haiki, e kaupalena ana i kona hiki ke kākoʻo i nā noi wideband a i ʻole multi-frequency. No ka laʻana, ʻo kahi antenna pepeiaohao loaʻa kiʻekiʻe i hoʻonohonoho pono ʻia no 2.0 GHz e paʻakikī paha e mālama i ka hana ma 1.70 GHz a i ʻole 2.60 GHz. I ka hoʻohālikelike ʻana, ʻoi aku ka maʻalahi o kahi antenna loaʻa haʻahaʻa me ka bandwidth ākea, e kūpono ai no nā noi e koi ana i ka agility alapine.

Ke kuhikuhi ʻana a me ka uhi ʻana
ʻO nā antennas loaʻa kiʻekiʻe, e like me nā mea hoʻomālamalama parabolic a i ʻole nā antenna pepeiaohao, ʻoi aku ka maikaʻi ma nā ʻōnaehana kamaʻilio kiko-a-kiko kahi e koʻikoʻi ai ka hoʻohui ʻana o ka hōʻailona. Eia nō naʻe, i nā hiʻohiʻona e koi ana i ka uhi omnidirectional, e like me ka hoʻolaha ʻana a i ʻole nā pūnaewele kelepona, hiki i ka beamwidth haiki o kahi antenna loaʻa kiʻekiʻe ke lilo i mea hemahema. No ka laʻana, kahi e hoʻouna ai nā antennas he nui i nā hōʻailona i hoʻokahi mea loaʻa, he mea nui ke kaulike ma waena o ka loaʻa a me ka uhi ʻana e hōʻoia i ka kamaʻilio hilinaʻi.

AESA vs. PESA: Loaʻa a me ka maʻalahi
I ka hoʻohālikelike ʻana i nā ʻenehana **AESA** a me **PESA**, ʻo ka loaʻa ʻana kekahi o nā kumu he nui e noʻonoʻo ai. ʻO nā ʻōnaehana AESA, e hoʻohana ana i nā modula hoʻouna/loaʻa pākahi no kēlā me kēia mea antenna, hāʻawi i ka loaʻa kiʻekiʻe aʻe, ka hoʻokele kukuna maikaʻi aʻe, a me ka hilinaʻi i hoʻomaikaʻi ʻia i hoʻohālikelike ʻia me nā ʻōnaehana PESA. Eia nō naʻe, ʻaʻole paha e kūpono ka paʻakikī a me ke kumukūʻai o AESA no nā noi āpau. ʻOiai ʻaʻole maʻalahi ka loli o nā ʻōnaehana PESA, hiki nō ke hāʻawi i ka loaʻa kūpono no nā hihia hoʻohana he nui, e hoʻolilo ana iā lākou i hopena kūpono i kekahi mau hiʻohiʻona.
Nā Manaʻo Kūpono
ʻO ke **1.70-2.60 GHz Standard Gain Horn Antenna** kahi koho kaulana no ka hoʻāʻo ʻana a me ke ana ʻana i nā ʻōnaehana microwave ma muli o kāna hana wānana a me ka loaʻa kūpono. Eia nō naʻe, pili kona kūpono i nā koi kikoʻī o ka noi. No ka laʻana, i loko o kahi ʻōnaehana radar e koi ana i ka loaʻa kiʻekiʻe a me ka kaohi kukuna pololei, makemake ʻia paha kahi AESA. I ka hoʻohālikelike ʻana, hiki i kahi ʻōnaehana kamaʻilio uea ʻole me nā koi wideband ke hoʻoikaika i ka bandwidth ma mua o ka loaʻa.
Hopena
ʻOiai hiki i ka loaʻa kiʻekiʻe ke hoʻomaikaʻi i ka ikaika hōʻailona a me ka laulā, ʻaʻole ia wale nō ke kumu hoʻoholo o ka hana holoʻokoʻa o kahi antenna. Pono e noʻonoʻo ʻia nā mea e like me ka **Antenna Bandwidth**, nā koi uhi, a me ka paʻakikī o ka ʻōnaehana. Pēlā nō, ʻo ke koho ma waena o nā ʻenehana **AESA** a me **PESA** e pili ana i nā pono kikoʻī o ka noi. I ka hopena, ʻo ka antenna "ʻoi aku ka maikaʻi" ka mea e kūpono loa i ka hana, ke kumukūʻai, a me nā koi hana o ka ʻōnaehana i hoʻolaha ʻia ai. He mea maikaʻi ka loaʻa kiʻekiʻe i nā hihia he nui, akā ʻaʻole ia he hōʻailona honua o kahi antenna ʻoi aku ka maikaʻi.
No ka ʻike hou aku e pili ana i nā antennas, e kipa i ka pūnaewele:
