Kwicandelo lobunjineli be-microwave, ukusebenza kwe-antenna yinto ebalulekileyo ekumiseleni ukusebenza kakuhle nokusebenza kakuhle kweenkqubo zonxibelelwano ezingenazingcingo. Enye yezona zihloko zixoxwa kakhulu kukuba ingaba inzuzo ephezulu ithetha i-antenna engcono na. Ukuze siphendule lo mbuzo, kufuneka siqwalasele iinkalo ezahlukeneyo zoyilo lwe-antenna, kubandakanya iimpawu ze-**Microwave Antenna**, **I-Antenna Bandwidth**, kunye nothelekiso phakathi kwe-**AESA (Active Electronically Scanned Array)** kunye ne-**PESA (Passive Electronically Scanned Array)**. Ukongeza, siza kuhlola indima ye-**1.70-2.60I-antenna ye-GHz Standard Gain Horn** ekuqondeni i-gain kunye neziphumo zayo.
Ukuqonda i-Antenna Gain
Ukwanda kwee-antenna sisilinganiso sokuba i-antenna iqondisa okanye igxila njani amandla erediyo (RF) kwicala elithile. Idla ngokubonakaliswa ngee-decibels (dB) kwaye ngumsebenzi wepateni yemitha ye-antenna. I-antenna ene-high-gain, efana ne-**I-Antenna yeHorn yeGain esemgangathweni** esebenza kuluhlu lwe **1.70-2.60 GHz**, igxila amandla kwi-beam emxinwa, enokuphucula kakhulu amandla esignali kunye noluhlu lonxibelelwano kwicala elithile. Nangona kunjalo, oku akuthethi ukuba inzuzo ephezulu isoloko ingcono.

Indima ye-Antenna Bandwidth
**I-Antenna Bandwidth** ibhekisa kuluhlu lweefrikhwensi apho i-antenna inokusebenza khona ngokufanelekileyo. I-antenna ene-high-gain inokuba ne-bandwidth encinci, nto leyo ethintela amandla ayo okuxhasa i-wideband okanye usetyenziso lwe-multi-frequency. Umzekelo, i-antenna ene-high-gain horn elungiselelwe i-2.0 GHz inokuba nzima ukugcina ukusebenza kwi-1.70 GHz okanye i-2.60 GHz. Ngokwahlukileyo koko, i-antenna ene-low-gain ene-bandwidth ebanzi inokuba ne-versatile ngakumbi, nto leyo eyenza ifaneleke kwii-application ezifuna i-frequency agility.

Ulwalathiso kunye nokugubungela
Ii-antenna ezifumana isandi esiphakamileyo, ezifana nee-parabolic reflectors okanye ii-antenna ze-horn, ziyagqwesa kwiinkqubo zonxibelelwano oluvela kwindawo ukuya kwindawo apho ugxininiso lwesignali lubalulekile. Nangona kunjalo, kwiimeko ezifuna ukugubungela yonke indawo, njengokusasaza okanye iinethiwekhi zeselfowuni, ububanzi obuncinci be-beamwidth ye-antenna efumana isandi esiphakamileyo bunokuba yingxaki. Umzekelo, apho ii-antenna ezininzi zithumela imiqondiso kwi-receiver enye, ibhalansi phakathi kokuxhamla kunye nokugubungela kubalulekile ukuqinisekisa unxibelelwano oluthembekileyo.

I-AESA vs. PESA: Ukuzuza kunye nokuguquguquka
Xa kuthelekiswa ubuchwepheshe be **AESA** kunye ne **PESA**, inzuzo yenye yezinto ezininzi ekufuneka ziqwalaselwe. Iinkqubo ze-AESA, ezisebenzisa iimodyuli zokudlulisa/zokwamkela nganye into ye-antenna, zibonelela ngenzuzo ephezulu, ukuqhutywa kwe-beam okungcono, kunye nokuthembeka okuphuculweyo xa kuthelekiswa neenkqubo ze-PESA. Nangona kunjalo, ubunzima obandayo kunye neendleko ze-AESA zisenokungavumeleki kuzo zonke izicelo. Iinkqubo ze-PESA, nangona zingaguquguquki kangako, zisenokubonelela ngenzuzo eyaneleyo kwiimeko ezininzi zokusetyenziswa, nto leyo ezenza zibe sisisombululo esingabizi kakhulu kwiimeko ezithile.
Izinto Ezibalulekileyo Omele Uziqwalasele
I-**1.70-2.60 GHz Standard Gain Horn Antenna** lukhetho oludumileyo lokuvavanya nokulinganisa kwiinkqubo ze-microwave ngenxa yokusebenza kwayo okuqikelelweyo kunye nokunyuka okuphakathi. Nangona kunjalo, ukufaneleka kwayo kuxhomekeke kwiimfuno ezithile zesicelo. Umzekelo, kwinkqubo yeradar efuna i-gain ephezulu kunye nolawulo oluchanekileyo lwe-beam, i-AESA inokukhethwa. Ngokwahlukileyo koko, inkqubo yonxibelelwano engenazingcingo eneemfuno ze-wideband inokubeka phambili i-bandwidth kune-gain.
Isiphelo
Nangona i-gain ephezulu inokuphucula amandla esignali kunye nobubanzi, ayisiyonto yodwa ebangela ukusebenza kwe-antenna iyonke. Izinto ezifana ne-**Antenna Bandwidth**, iimfuno zokugubungela, kunye nobunzima benkqubo nazo kufuneka ziqwalaselwe. Ngokufanayo, ukhetho phakathi kobuchwepheshe be-**AESA** kunye ne-**PESA** luxhomekeke kwiimfuno ezithile zesicelo. Ekugqibeleni, i-antenna "engcono" yileyo ihlangabezana ngcono nokusebenza, iindleko, kunye neemfuno zokusebenza kwenkqubo apho isetyenziswa khona. I-gain ephezulu inenzuzo kwiimeko ezininzi, kodwa ayilulo uphawu oluqhelekileyo lwe-antenna engcono.
