Emkhakheni wobunjiniyela be-microwave, ukusebenza kwe-antenna kuyisici esibalulekile ekunqumeni ukusebenza kahle nokusebenza kwezinhlelo zokuxhumana ezingenazintambo. Esinye sezihloko okuphikiswana ngaso kakhulu ukuthi ukuzuza okuphezulu ngokwemvelo kusho i-antenna engcono. Ukuze siphendule lo mbuzo, kufanele sicabangele izici ezihlukahlukene zomklamo we-antenna, okuhlanganisa izici ze-***Microwave Antenna**, **I-Antenna Bandwidth**, kanye nokuqhathanisa phakathi kobuchwepheshe be-***AESA (Active Electronically Scanned Array)** kanye ne-**PESA (Passive Electronically Scanned Array)**. Ukwengeza, sizohlola indima ye- **1.70-2.60I-GHz Standard Gain Horn Antenna** ekuqondeni inzuzo nemithelela yayo.
Ukuqonda Ukuzuza kwe-Antenna
Ukuzuza kwe-antenna isilinganiso sokuthi uthi luwaqondisa noma agxilise kahle kangakanani amandla omsakazo (RF) ohlangothini oluthile. Ngokuvamile kuvezwa ngama-decibel (dB) futhi kuwumsebenzi wephethini yemisebe yothi. I-antenna enenzuzo ephezulu, njenge-**I-Standard Gain Horn Antenna** esebenza ku-*1.70-2.60 GHz** ububanzi, igxilisa amandla ensikeni encane, engathuthukisa kakhulu amandla esignali nobubanzi bokuxhumana ohlangothini oluthile. Nokho, lokhu akusho ngempela ukuthi inzuzo ephakeme ihlala ingcono.

Iqhaza Le-Antenna Bandwidth
**I-Antenna Bandwidth** ibhekisela ezinhlobonhlobo zamafrikhwensi okuthi uthingo lusebenze kahle. I-antenna enenzuzo ephezulu ingase ibe nomkhawulokudonsa omncane, ikhawulele amandla ayo okusekela i-wideband noma izinhlelo zokusebenza zamafrikhwensi amaningi. Isibonelo, i-antenna yophondo lwenzuzo ephezulu ethuthukiselwe i-2.0 GHz ingase ibe nzima ukugcina ukusebenza ku-1.70 GHz noma ku-2.60 GHz. Ngokuphambene, i-antenna enenzuzo ephansi enomkhawulokudonsa obanzi ingase ibe nezinto ezihlukahlukene, iyenze ifanelekele izinhlelo zokusebenza ezidinga ukusebenza kahle kwemvamisa.

Ukuqondisa kanye Nokufakwa
Ama-antenna anenzuzo ephezulu, njengezibonisi ze-parabolic noma izimpondo zophondo, ahamba phambili ezinhlelweni zokuxhumana ze-point-to-point lapho ukugxilisa kwesignali kubalulekile. Kodwa-ke, ezimeni ezidinga ukumbozwa kwe-omnidirectional, njengokusakaza noma amanethiwekhi eselula, ukuphakama okuncane kwe-antenna kungase kube ukonakala. Isibonelo, lapho izimpondo eziningi zidlulisela amasignali kumamukeli oyedwa, ibhalansi phakathi kwenzuzo nokufakwa kubalulekile ukuze kuqinisekiswe ukuxhumana okuthembekile.

I-AESA vs. PESA: Ukuzuza Nokuvumelana nezimo
Uma uqhathanisa ubuchwepheshe be-**AESA** kanye ne-**PESA**, ukuzuza kungenye yezici eziningi okufanele icatshangelwe. Amasistimu e-AESA, asebenzisa amamojula okudlulisa/okwamukela ngakunye ku-elementi ngayinye ye-antenna, anikeza inzuzo ephezulu, isiqondiso esingcono se-beam, nokuthembeka okuthuthukisiwe uma kuqhathaniswa nezinhlelo ze-PESA. Kodwa-ke, ukwanda kobunzima kanye nezindleko ze-AESA kungenzeka kungathethelelwa kuzo zonke izinhlelo zokusebenza. Izinhlelo ze-PESA, nakuba zingaguquguquki kancane, zisenganikeza inzuzo eyanele ezimweni eziningi zokusetshenziswa, okuzenza zibe yisixazululo esingabizi kakhulu ezimeni ezithile.
Ukucatshangelwa Okuwusizo
**1.70-2.60 GHz Standard Gain Horn Antenna** iyinketho edumile yokuhlola nokulinganisa kumasistimu we-microwave ngenxa yokusebenza kwayo okubikezelwe kanye nenzuzo emaphakathi. Nokho, ukufaneleka kwayo kuncike ezidingweni ezithile zohlelo lokusebenza. Isibonelo, kusistimu ye-radar edinga inzuzo ephezulu kanye nokulawulwa kwe-beam okunembile, i-AESA ingase ikhethwe. Ngokuphambene, isistimu yokuxhumana engenantambo enezidingo ze-wideband ingase ibeke phambili umkhawulokudonsa kunenzuzo.
Isiphetho
Nakuba ukuzuza okuphezulu kungathuthukisa amandla esignali nobubanzi, akusona sodwa esinqumayo sokusebenza kukonke kwe-antenna. Izinto ezifana ne-***I-Antenna Bandwidth**, izidingo zekhava, nobunzima besistimu nakho kufanele kucatshangelwe. 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. Ukuzuza okuphezulu kunenzuzo ezimweni eziningi, kodwa akuyona inkomba yendawo yonke ye-antenna engcono.
