Akụkọ ihe mere eme

Echiche nkeantenna nhaziỌ malitere n'afọ 1930, e mekwara ya na mbụ site na ọtụtụ ihe e ji antenna mee ka arụmọrụ nke nkwukọrịta na sistemụ radar ka mma. Site na ọganihu nke teknụzụ, antenna array aghọọla sistemụ zuru oke nke nwere ọtụtụ ihe e ji antenna mee, nke nwere ike ime ka nhazi mgbaàmà dị mgbagwoju anya na ịkpụpụta ụdọ. Na afọ 1950, a malitere iji antenna array eme ihe n'ọtụtụ ebe n'ọgbọ agha na ụgbọelu. Mgbe nke ahụ gasịrị, site na mmepe nke microwave na teknụzụ nkwukọrịta, ejiri antenna array mee ihe n'ọhịa dịka nkwukọrịta satịlaịtị, radar, nkwukọrịta mkpanaka na netwọk ikuku.

Ụkpụrụ ọrụ

Antenna array bụ sistemụ antenna nke nwere ọtụtụ ihe antenna nke edobere n'ime geometry na oghere pụrụ iche. Ụkpụrụ ọrụ nke antenna array dabere na echiche nke imepụta beam na ntụaka beam.

Mgbe ebili mmiri rutere na antenna array, ihe antenna ọ bụla na-enweta otu ebili mmiri ahụ na-enwe oge nkwụsị nke usoro dị iche. A na-enweta oge nkwụsị nke usoro dị n'etiti ihe antenna ndị a site na ịgbanwe ahịrị igbu oge ma ọ bụ mgbanwe nke usoro na sekit ahụ. Site na ịgbanwe oge nkwụsị nke ihe antenna ọ bụla, enwere ike ijikwa njikọ na nnyonye anya nke ebili mmiri ihe merenụ na usoro ahụ.

Site na njikwa igbu oge nke usoro ezi uche dị na ya, antenna nhazi nwere ike ịmepụta ụdọ. Ụdọ na-ezo aka na isi ntụziaka nke ike nke antenna na-ekesa, nke yiri ụdọ ìhè ma ọ bụ ụdọ ụda nke a tụrụ n'otu ntụziaka kpọmkwem. Site n'ịgbanwe igbu oge nke ihe antenna ọ bụla, enwere ike itinye ebili mmiri na-abata n'elu ma melite ya n'akụkụ ụfọdụ ma kagbuo ma belata ya n'akụkụ ndị ọzọ. N'ụzọ dị otu a, antenna nhazi nwere ike ịmepụta ụdọ dị warara ma dị n'akụkụ, si otú a na-eme ka uru na nduzi nke sistemụ antenna dịkwuo elu.

Enwere ike ịgbanwe usoro ntụgharị nke antenna array site na ịgbanwe oge nkwụsị nke usoro. Site na ijikwa oge nkwụsị nke usoro, enwere ike ịgbanwe akụkụ ntụaka nke ogwe ahụ ka ọ gaa n'ebe ebumnuche ma ọ bụ mpaghara mmasị dị. Nke a na-eme ka antenna array nwee ngwa dị mkpa na sistemụ radar, sistemụ nkwukọrịta na netwọk ikuku, ma nwee ike imezu ọrụ dịka nsuso ebumnuche, ntụziaka mgbaama na mkagbu nnyonye anya.

Na mgbakwunye na nhazi ìhè na nduzi, antenna array nwekwara uru ndị ọzọ, dịka ịgbasa oghere, ikike mgbochi nnyonye anya, na mgbanwe. Site n'iji mmekọrịta dị n'etiti ihe antenna dị na array eme ihe, enwere ike ịnweta ma bufee ọtụtụ akara ngosi n'otu oge, si otú a na-eme ka ikike sistemụ na arụmọrụ dịkwuo elu.

Na nchịkọta, antenna array na-enweta nhazi na nduzi site na ịgbanwe oge nke ihe antenna ọ bụla iji nweta radieshon na nnabata ka mma n'akụkụ ụfọdụ. Ha nwere ọtụtụ ngwa na nkwukọrịta, radar na netwọk ikuku, na-enye uru dị ka uru dị elu, nduzi na mgbanwe.
