Ekwakhiweni kwe-antenna ye-microwave, inzuzo ephezulu idinga ukulinganisela ukusebenza kanye nokusebenza kahle. Nakuba inzuzo ephezulu ingathuthukisa amandla esignali, izoletha izinkinga ezifana nosayizi okhuphukile, izinselele zokushabalalisa ukushisa kanye nezindleko ezikhuphukile. Okulandelayo yizinto ezibalulekile okufanele uzicabangele:
1. Ukufanisa inzuzo nesicelo
Isiteshi sesisekelo se-5G (i-millimeter wave AAU):24-28dBi, kudingai-vacuum brazingipuleti lokupholisa amanzi ukuqinisekisa ukusebenza kwamandla aphezulu isikhathi eside.
Ukuxhumana ngesathelayithi (ibhendi ye-Ka):40-45dBi, ukuthembela ekupholiseni kwamanzi epayipi lethusi eligqitshwe phansi ukuze kuxazululwe inkinga yokushabalaliswa kokushisa kwama-antenna amakhulu avulekayo.
Impi/i-radar ye-elekthronikhi:20-30dBi, kusetshenziswa ukupholisa uketshezi lokushisela nge-stir friction ukuze kuvumelane nomthwalo wokushisa ophezulu.
Ukuhlolwa kwe-EMC:10-15dBi, isinki yokushisa evamile yokushisela ingahlangabezana nezidingo.

2. Imikhawulo yobunjiniyela yenzuzo ephezulu
Imbobo yokushabalalisa ukushisa: Ama-antenna angaphezu kwama-25dBi ngokuvamile adinga ukupholisa uketshezi (njengokubhoboza nge-vacuum noma ipuleti lokupholisa amanzi elipholisa nge-stir friction welding), ngaphandle kwalokho amandla okusebenza anqunyelwe.
Imikhawulo yosayizi: Ama-antenna angaphezu kuka-30dBi angadlula imitha eli-1 ebhendini lika-Ka, futhi ukwakheka kwesakhiwo kudinga ukulungiswa.
Izici Zezindleko: Ngokwanda ngakunye kwe-3dB kwenzuzo, izindleko zesistimu yokupholisa zingase zikhuphuke ngo-20%-30%.

3. Iziphakamiso zokwenza ngcono
Beka phambili izidingo zohlelo lokusebenza lokufanisa futhi ugweme ukuphishekela ngokweqile inzuzo ephezulu.
Isixazululo sokupholisa sinquma umthamo wamandla, futhi ama-antenna athola amandla amaningi kumele afakwe ukupholisa okusebenzayo (njengokupholisa uketshezi).
Linganisa i-bandwidth kanye nenzuzo. Izinhlelo ze-Narrowband zingaphishekela inzuzo ephezulu, futhi izinhlelo ze-broadband zidinga ukwenza izivumelwano ezifanele.
Isiphetho: Ukuzuza okuhle kakhulu kuncike ekusetshenzisweni okuthile, ngokuvamile phakathi kuka-20-35dBi, futhi kudinga ukuhlanganiswa nobuchwepheshe bokupholisa obuthuthukisiwe (njengokufaka i-vacuum brazing noma ukupholisa amanzi nge-stir friction welding) ukuqinisekisa ukusebenza okuthembekile.
Ukuze ufunde kabanzi ngama-antenna, sicela uvakashele:
