Emkhakheni wobunjiniyela be-microwave, ukusebenza kwe-antenna kuyisici esibalulekile ekunqumeni ukusebenza kahle kanye nokusebenza kahle kwezinhlelo zokuxhumana ezingenantambo. Esinye sezihloko ezixoxwa kakhulu ukuthi inzuzo ephezulu isho i-antenna engcono yini. Ukuze siphendule lo mbuzo, kumele sicabangele izici ezahlukahlukene zomklamo we-antenna, okuhlanganisa izici ze-**Microwave Antenna**, **I-Antenna Bandwidth**, kanye nokuqhathaniswa phakathi kobuchwepheshe be-**AESA (Active Electronically Scanned Array)** kanye ne-**PESA (Passive Electronically Scanned Array)**. Ngaphezu kwalokho, sizohlola indima ye-**1.70-2.60I-antenna ye-GHz Standard Gain Horn** ekuqondeni inzuzo kanye nemiphumela yayo.
Ukuqonda Ukuzuza Kwe-Antenna
Ukwanda kwe-antenna kuyisilinganiso sokuthi i-antenna iqondisa noma igxilisa kahle kangakanani amandla e-radio frequency (RF) ohlangothini oluthile. Ngokuvamile ivezwa ngama-decibel (dB) futhi iwumsebenzi wephethini yemisebe ye-antenna. I-antenna enenzuzo ephezulu, njenge-**I-Antenna Ejwayelekile Yokuthola Uphondo** esebenza kububanzi be-**1.70-2.60 GHz**, igxilisa amandla emsebeni omncane, okungathuthukisa kakhulu amandla esignali kanye nobubanzi bokuxhumana ohlangothini oluthile. Kodwa-ke, lokhu akusho ukuthi inzuzo ephezulu ihlala ingcono.

Indima ye-Antenna Bandwidth
**I-Antenna Bandwidth** ibhekisela ebangeni lamafrikhwensi lapho i-antenna ingasebenza khona ngempumelelo. I-antenna enenzuzo ephezulu ingaba nomkhawulokudonsa omncane, okunciphisa ikhono layo lokusekela izinhlelo zokusebenza ze-wideband noma ze-multi-frequency. Isibonelo, i-antenna enenzuzo ephezulu eyenzelwe i-2.0 GHz ingase ibe nobunzima bokugcina ukusebenza ku-1.70 GHz noma ku-2.60 GHz. Ngokuphambene nalokho, i-antenna enenzuzo encane ene-bandwidth ebanzi ingase ibe nokuguquguquka okuningi, okwenza ifanele izinhlelo zokusebenza ezidinga ukuguquguquka kwamafrikhwensi.

Ukuqondiswa kanye Nokumbozwa
Ama-antenna athola i-high gain, njenge-parabolic reflectors noma ama-antenna e-horn, ahamba phambili ezinhlelweni zokuxhumana ezikhomba iphuzu kuya iphuzu lapho ukugxilisa isignali kubalulekile khona. Kodwa-ke, ezimweni ezidinga ukumbozwa okuqondile, njengokusakaza noma amanethiwekhi eselula, ububanzi obuncane be-beamwidth ye-antenna ethola i-high gain bungaba yiphutha. Isibonelo, lapho ama-antenna amaningi edlulisela khona amasignali kumukeli oyedwa, ibhalansi phakathi kokutholakala nokumbozwa kubalulekile ukuqinisekisa ukuxhumana okuthembekile.

I-AESA vs. I-PESA: Inzuzo Nokuguquguquka
Uma kuqhathaniswa ubuchwepheshe be-**AESA** kanye ne-**PESA**, inzuzo ingenye yezinto eziningi okufanele uzicabangele. Izinhlelo ze-AESA, ezisebenzisa amamojula okudlulisa/okwamukela ngamanye isici se-antenna, zinikeza inzuzo ephezulu, ukuqondisa okungcono kwe-beam, kanye nokuthembeka okuthuthukisiwe uma kuqhathaniswa nezinhlelo ze-PESA. Kodwa-ke, ubunzima obandayo kanye nezindleko ze-AESA kungenzeka kungafaneleki kuzo zonke izinhlelo zokusebenza. Izinhlelo ze-PESA, nakuba zingaguquguquki kakhulu, zisenganikeza inzuzo eyanele ezimweni eziningi zokusetshenziswa, okwenza zibe yisisombululo esingabizi kakhulu ezimweni ezithile.
Izinto Ezibalulekile Okufanele Uzicabangele
I-**1.70-2.60 GHz Standard Gain Horn Antenna** iyindlela ethandwayo yokuhlola nokulinganisa ezinhlelweni ze-microwave ngenxa yokusebenza kwayo okubikezelwayo kanye nokuzuza okulinganiselwe. Kodwa-ke, ukufaneleka kwayo kuncike ezidingweni ezithile zohlelo lokusebenza. Isibonelo, ohlelweni lwe-radar oludinga inzuzo ephezulu kanye nokulawulwa okunembile kwe-beam, i-AESA ingase ikhethwe. Ngokuphambene nalokho, uhlelo lokuxhumana olungenantambo olunezidingo ze-wideband lungase lubeke phambili i-bandwidth kunenzuzo.
Isiphetho
Nakuba inzuzo ephezulu ingathuthukisa amandla esignali kanye nobubanzi, akuyona yodwa into enquma ukusebenza kwe-antenna iyonke. Izici ezifana ne-**Antenna Bandwidth**, izidingo zokumboza, kanye nobunzima besistimu nazo kumele zicatshangelwe. Ngokufanayo, ukukhetha phakathi kobuchwepheshe be-**AESA** kanye ne-**PESA** kuncike ezidingweni ezithile zohlelo lokusebenza. Ekugcineni, i-antenna "engcono" yileyo ehlangabezana kangcono nokusebenza, izindleko, kanye nezidingo zokusebenza zesistimu lapho isetshenziswa khona. Inzuzo ephezulu inenzuzo ezimweni eziningi, kodwa akuyona inkomba yendawo yonke ye-antenna engcono.
