Ekwakhiweni kwe-antenna ye-microwave, ukuzuza okuphelele kudinga ukulinganisa ukusebenza nokusebenza. Nakuba ukuzuza okuphezulu kungathuthukisa amandla esignali, kuzoletha izinkinga ezifana nobukhulu obukhulayo, izinselele zokulahla ukushisa kanye nezindleko ezikhulayo. Okulandelayo yizinto ezibalulekile zokucatshangelwa:
1. Ukuqhathanisa inzuzo nesicelo
Isiteshi sesisekelo se-5G (i-millimeter wave AAU):24-28dBi, idingai-vacuum brazingipuleti lokupholisa amanzi ukuze kuqinisekiswe ukusebenza kwamandla aphezulu kwesikhathi eside.
Ukuxhumana ngesathelayithi (Ka band):40-45dBi, ethembele ekupholiseni amanzi eshubhu yethusi elingcwatshiwe ukuze kuxazululwe inkinga yokukhipha ukushisa kwezimpondo ezinkulu zokuvula.
Impi kagesi/irada:20-30dBi, kusetshenziswa ukupholisa kwe-stir friction welding liquid ukuzivumelanisa nomthwalo wokushisa oshukumisayo ophezulu.
Ukuhlolwa kwe-EMC:10-15dBi, usinki wokushisa owejwayelekile ungahlangabezana nezidingo.
I-Cassegrain Antenna (40dBi)
I-Circularly Polarized Horn Antenna (20dBi)
2. Imikhawulo yobunjiniyela yenzuzo ephezulu
Ibhodlela lokukhipha ukushisa: Ama-antenna angaphezu kuka-25dBi ngokuvamile adinga ukupholisa okuwuketshezi (okufana ne-vacuum brazing noma ipuleti lokupholisa le-ward friction welding), ngaphandle kwalokho umthamo wamandla unomkhawulo.
Izingqinamba zosayizi: Ama-antenna angaphezu kuka-30dBi angase eqe imitha elingu-1 kubhendi ye-Ka, futhi umklamo wesakhiwo udinga ukuthuthukiswa.
Izindleko: Kukho konke ukukhuphuka okungu-3dB kwenzuzo, izindleko zesistimu yokupholisa zingase zikhuphuke ngo-20% -30%.
I-Planar Antenna (30dBi)
I-Dual Circular Polarized Horn Antenna(10dBi)
3. Iziphakamiso zokuthuthukisa
Beka kuqala izidingo zesicelo esifanayo futhi ugweme ukuphishekela inzuzo enkulu ngokweqile.
Isixazululo sokupholisa sinquma umthamo wamandla, futhi izimpondo ezinenzuzo ephezulu kufanele zifakwe ukupholisa okuphumelelayo (okufana nokupholisa uketshezi).
Linganisa umkhawulokudonsa kanye nenzuzo. Amasistimu we-Narrowband angaphishekela inzuzo ephezulu, futhi amasistimu e-broadband adinga ukwenza ukuvumelana okufanele.
Isiphetho: Ukuzuza okuphelele kuncike ohlelweni oluthile, ngokuvamile oluphakathi kuka-20-35dBi, futhi ludinga ukuhlanganiswa nobuchwepheshe bokupholisa obuthuthukisiwe (okufana nokufaka i-vacuum brazing noma ukupholisa amanzi okushisela ukushayisana) ukuze kuqinisekiswe ukusebenza okuthembekile.
Ukuze ufunde kabanzi ngama-antenna, sicela uvakashele:
