Ma ke kahua o ka ʻenehana microwave, ʻo ka hana antenna kahi mea koʻikoʻi i ka hoʻoholo ʻana i ka pono a me ka pono o nā ʻōnaehana kamaʻilio uea. ʻO kekahi o nā kumuhana i hoʻopaʻapaʻa nui ʻia inā ʻoi aku ka kiʻekiʻe o ka loaʻa ʻana o ka antenna ʻoi aku ka maikaʻi. No ka pane ʻana i kēia nīnau, pono mākou e noʻonoʻo i nā ʻano like ʻole o ka hoʻolālā antenna, me nā hiʻohiʻona **Microwave Antenna**, **Antenna Bandwidth**, a me ka hoʻohālikelike ʻana ma waena o **AESA (Active Electronically Scanned Array)** a me **PESA (Passive Electronically Scanned Array)** ʻenehana. Eia hou, 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.
Hoʻomaopopo i ka Antenna Gain
ʻO ka loaʻa ʻana o ka Antenna kahi ana o ka maikaʻi o ke alakaʻi ʻana a i ʻole ka hoʻopaʻa ʻana o ka antenna i ka ikehu lekiō (RF) i kahi kuhikuhi kikoʻī. Hōʻike maʻamau ia i nā decibels (dB) a he hana ia o ke ʻano radiation o ka antenna. ʻO kahi antena kiʻekiʻe, e like me kahi **Antenna Gain Horn maʻamau** e hana ana ma ka laina **1.70-2.60 GHz**, e kālele ana i ka ikehu i loko o kahi kukuna haiki, hiki ke hoʻomaikaʻi nui i ka ikaika hōʻailona a me ka laulā kamaʻilio ma kekahi ʻaoʻao. Eia naʻe, ʻaʻole ia he manaʻo ʻoi aku ka maikaʻi o ka loaʻa kiʻekiʻe.

ʻO ke kuleana o ka Antenna Bandwidth
**Antenna Bandwidth** pili i ka laulā o nā alapine e hiki ai i kahi antenna ke hana pono. Loaʻa paha i kahi antenna kiʻekiʻe ka bandwidth haiki, e kaupalena ana i kona hiki ke kākoʻo i nā noi wideband a i ʻole nā nui-frequency. No ka laʻana, paʻakikī paha kahi antenna pu kiʻekiʻe i hoʻopaʻa ʻia no 2.0 GHz e mālama i ka hana ma 1.70 GHz a i ʻole 2.60 GHz. ʻO ka ʻokoʻa, ʻoi aku ka maʻalahi o ka antenna haʻahaʻa me ka bandwidth ākea, e kūpono ana i nā noi e koi ana i ka wikiwiki pinepine.

Ke kuhikuhi a me ka uhi
ʻO nā antenna kiʻekiʻe, e like me nā parabolic reflectors a i ʻole horn antennas, ʻoi aku ka maikaʻi i nā ʻōnaehana kamaʻilio point-to-point kahi e koʻikoʻi ai ka hoʻopaʻa ʻana i 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 paʻa lima, hiki ke lilo i mea pōʻino ka laulaʻa haiki o ka antenna kiʻekiʻe. No ka laʻana, kahi e hoʻouna ai nā antenna he nui i nā hōʻailona i kahi mea hoʻokipa hoʻokahi, pono ke kaulike ma waena o ka loaʻa a me ka uhi e hōʻoia i ka kamaʻilio hilinaʻi.

AESA vs. PESA: Loaʻa a me ka hiki ke hoʻololi
Ke hoʻohālikelike nei i nā ʻenehana **AESA** a me **PESA**, ʻo ka loaʻa kekahi o nā kumu he nui e noʻonoʻo ai. ʻO nā ʻōnaehana AESA, e hoʻohana ana i nā modula hoʻouna / loaʻa i kēlā me kēia mea antenna, hāʻawi i ka loaʻa kiʻekiʻe, ʻoi aku ka maikaʻi o ka hoʻokele beam, a me ka hilinaʻi i hoʻohālikelike ʻia me nā ʻōnaehana PESA. Eia nō naʻe, ʻaʻole ʻae ʻia ka piʻi ʻana o ka paʻakikī a me ke kumukūʻai o AESA no nā noi āpau. Hiki i nā ʻōnaehana PESA, ʻoiai ʻaʻole hiki ke maʻalahi, hiki ke hāʻawi i ka waiwai kūpono no nā hihia hoʻohana he nui, e hoʻolilo iā lākou i ʻoi aku ka maikaʻi o ke kumu kūʻai i kekahi mau hiʻohiʻona.
Nā Manaʻo Hoʻomaʻamaʻa
ʻO ka **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 haʻahaʻa. Eia naʻe, pili kona kūpono i nā koi kūikawā o ka noi. No ka laʻana, i loko o kahi ʻōnaehana radar e koi ana i ka loaʻa kiʻekiʻe a me ka hoʻomalu ʻana i ke kukui pololei, makemake ʻia kahi AESA. ʻO ka ʻokoʻa, ʻo kahi ʻōnaehana kamaʻilio uea me nā koi wideband hiki ke hoʻonui i ka bandwidth ma mua o ka loaʻa.
Ka hopena
ʻOiai hiki i ka loaʻa kiʻekiʻe ke hoʻomaikaʻi i ka ikaika hōʻailona a me ka laulā, ʻaʻole ʻo ia wale nō ka mea e hoʻoholo ai i ka hana holoʻokoʻa o kahi antenna. Pono e noʻonoʻo ʻia nā mea e like me **Antenna Bandwidth**, nā koi uhi, a me ka paʻakikī o ka ʻōnaehana. Pēlā nō, pili ka koho ma waena o **AESA** a me **PESA** i nā pono kikoʻī o ka noi. ʻO ka hope loa, ʻo ka antenna "ʻoi aku ka maikaʻi" ʻoi aku ka maikaʻi o ka hoʻokō ʻana i ka hana, ke kumukūʻai, a me nā koi hana o ka ʻōnaehana i kau ʻia ai. ʻOi aku ka maikaʻi o 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 antenna, e kipa:
