Mu rwego rw’ikoranabuhanga rya mikoroonde, imikorere ya antene ni ikintu cy’ingenzi mu kugena imikorere n’ubushobozi bwa sisitemu z’itumanaho ridafite insinga. Kimwe mu bintu bikunze kuganirwaho ni ukumenya niba inyungu nyinshi mu buryo busanzwe bivuze antene nziza. Kugira ngo dusubize iki kibazo, tugomba gusuzuma ibintu bitandukanye byo gushushanya antene, harimo imiterere ya antene za mikoroonde, *Bandwidth ya antene,* n’igereranya hagati ya ikoranabuhanga rya **AESA (Active Electronically Scanned Array)** na **PESA (Passive Electronically Scanned Array)**. Byongeye kandi, tuzasuzuma uruhare rwa **1.70-2.60Antena ya GHz Standard Gain Horn** mu gusobanukirwa inyungu n'ingaruka zayo.
Gusobanukirwa Inyungu ya Antena
Inyongera y'umurambararo ni igipimo cy'uburyo antene iyobora cyangwa ishyira imbaraga z'umurambararo wa radiyo (RF) mu cyerekezo runaka. Ubusanzwe igaragara muri desibeli (dB) kandi ni imikorere y'imiterere y'imirasire ya antene. Antene ifite inyungu nyinshi, nka **Antena y'ihembe ry'umusaruro usanzwe** ikora mu rugero rwa **1.70-2.60 GHz**, yinjiza ingufu mu muyoboro muto, bishobora kongera cyane imbaraga z'amajwi n'urwego rw'itumanaho mu cyerekezo runaka. Ariko, ibi ntibivuze ko inyungu nyinshi zihora ari nziza kurushaho.

Uruhare rwa Bandwidth ya Antena
**Umurambararo wa Antena** yerekeza ku rugero rw'imirongo antena ishobora gukora neza. Antena ifite ubushobozi bwo gukurura cyane ishobora kugira umurambararo muto, bigatuma ubushobozi bwayo bwo gushyigikira umurambararo munini cyangwa porogaramu za frequency nyinshi bugabanuka. Urugero, antena ifite ubushobozi bwo gukurura cyane yagenewe 2.0 GHz ishobora kugorwa no kugumana imikorere kuri 1.70 GHz cyangwa 2.60 GHz. Mu buryo bunyuranye, antena ifite ubushobozi bwo gukurura buhoro buhoro ifite umurambararo munini ishobora kuba ifite ubushobozi bwo gukora ibintu byinshi, bigatuma ikoreshwa neza mu bikorwa bisaba ubushobozi bwo gukurura.

Uburyo bwo kuyobora no gukwirakwiza amakuru
Antene zigaragaza ubushobozi bwo gukwirakwiza amakuru, nka parabolic reflectors cyangwa antene zigaragaza ubushobozi bwo gusohora amakuru, zirakora neza mu buryo bw'itumanaho aho gushyira ibimenyetso mu buryo bugaragara ari ingenzi cyane. Ariko, mu bihe bisaba ko amakuru akoreshwa mu buryo butandukanye, nko mu gusakaza amakuru cyangwa imiyoboro ya telefoni, ubugari bw'umurambararo muto wa antene zigaragaza ubushobozi bwo gukwirakwiza amakuru bushobora kuba ikibazo. Urugero, aho antene nyinshi zohereza ibimenyetso ku muntu umwe, uburinganire hagati y'ubushobozi bwo gukwirakwiza amakuru no kuyashyira mu buryo ni ingenzi kugira ngo habeho itumanaho ryizewe.

AESA vs. PESA: Inyungu n'Ubworoherane
Mu kugereranya ikoranabuhanga rya **AESA** na **PESA**, inyungu ni kimwe mu bintu byinshi bigomba kwitabwaho. Sisitemu za AESA, zikoresha modules zo kohereza/kwakira buri gice cya antene, zitanga inyungu nyinshi, kuyobora neza, kandi zikagira icyizere gihagije ugereranije na sisitemu za PESA. Ariko, kwiyongera kw'ubugoranye n'ikiguzi cya AESA bishobora kuba bidakwiye gukoreshwa muri porogaramu zose. Sisitemu za PESA, nubwo zidahinduka cyane, zishobora gutanga inyungu ihagije ku mikoreshereze myinshi, bigatuma ziba igisubizo gihendutse mu bihe bimwe na bimwe.
Ibitekerezo bifatika
Antena ya **1.70-2.60 GHz Standard Gain Horn** ni amahitamo akunzwe yo gupima no gupima muri sisitemu za mikoroonde bitewe n'imikorere yayo itegerejwe ndetse n'ubwiyongere buri hagati. Ariko, kuba ikwiriye biterwa n'ibisabwa byihariye na porogaramu. Urugero, muri sisitemu ya radar isaba kwiyongera cyane no kugenzura neza imirasire, AESA ishobora kuba nziza. Mu buryo bunyuranye, sisitemu y'itumanaho idakoresha insinga ifite ibisabwa na interineti nini ishobora gushyira imbere bandwidth kuruta kwiyongera.
Umwanzuro
Nubwo kwiyongera kw'amajwi bishobora kongera imbaraga z'amajwi n'uburebure bw'amajwi, si yo yonyine igena imikorere rusange ya antene. Ibintu nka **Antena Bandwidth**, ibisabwa mu gukwirakwiza amakuru, n'ubuhanga bwa sisitemu nabyo bigomba kuzirikanwa. Mu buryo nk'ubwo, guhitamo hagati y'ikoranabuhanga rya **AESA** na **PESA** biterwa n'ibyo porogaramu ikeneye. Amaherezo, antene "nziza" ni imwe ihuye neza n'imikorere, ikiguzi, n'ibisabwa mu mikorere ya sisitemu ikoreshwamo. Kuzamuka kw'amajwi ni ingirakamaro mu bihe byinshi, ariko si ikimenyetso rusange cy'antene nziza.
