Indlela Ama-PCB E-Antenna Anezigaba Ezihlanganisiwe Anika Ngayo Amandla Izinhlelo Zokuvikela Zomoya Zesizukulwane Esilandelayo
Njengoba izikhali zokulwa eziyimfihlo zesizukulwane sesihlanu kanye nemicibisholo ye-hypersonic zivela njengezinsongo ezibucayi, ama-radar endabuko askeniwe ngomshini alwela ukuzivumelanisa nezimo zempi ezishintsha ngokushesha. I-radar ye-array ehlukaniswe ngezigaba, enamakhono ayo okuqondisa angenawo umfutho kanye namakhono okulandelela ama-multi-target, isibe umgogodla wezinhlelo zokuvikela umoya zesizukulwane esilandelayo. Enhliziyweni yale ntuthuko yezobuchwepheshe kukhona i-PCB ye-antenna ye-array ehlukaniswe ngezigaba - iqhawe elingadunyiswanga ngemuva kwezinhlelo ze-radar ezithuthukisiwe.
1. Iyini i-Phased Array Antenna PCB?
I-PCB ye-antenna ye-phased array iyibhodi yesekethe enemvamisa ephezulu eyenzelwe ukulawula ukuqondisa okusebenzayo kwe-beam ezinhlelweni ze-radar. Ngaphandle kwesidingo sokujikeleza ngomshini, ivumela ukuskena okusheshayo kanye nokulandelela ngesikhathi esisodwa kwama-target amaningi, okwenza kube yingxenye ebalulekile kubuchwepheshe be-radar ye-phased array.
2. Izinzuzo Ezintathu Eziyinhloko Zokuvumela Ama-PCB E-Phased Array Antenna
Ukusebenza Okukhulu Kokuvama Nokusebenza Okubanzi:
Okubalulekile ekulweni nezinsongo ezifihliwe, lawa ma-PCB asebenzisa izinto ezithuthukisiwe njenge-Rogers noma i-Taconic high-frequency laminates, esekela ama-Ka/Ku bands kanye nama-millimeter-wave frequency akwazi ukungena ezimbozweni ezifihliwe.
Ubuqotho Besignali:
Ukulawulwa kwe-impedance okunembile kanye nomklamo womugqa wokudlulisela olahlekelwa kancane kuqinisekisa ukusabalala kwesignali okuzinzile ngesivinini esiphezulu ngaphakathi kwama-antenna ayinkimbinkimbi.

Ukwenziwa kwe-miniaturization kanye nokusebenza okuthuthukisiwe kufezwa ngama-microvia kanye nobuchwepheshe bokufaka i-stacking, kuhlanganisa izinkulungwane zamamojula okudlulisa/okwamukela (T/R) ngaphakathi kwesikhala esilinganiselwe. Lokhu kwenza isikhala se-antenna sibe sincane njenge-≤0.5λ, okuthuthukisa kakhulu ukunemba kokuqondisa kwe-beam. Izingxenye ezifakiwe njenge-capacitors kanye nama-resistors ngaphakathi kwezingqimba ze-PCB zinciphisa ubude bendlela yesignali, zinciphisa ukubambezeleka nomsindo.
Ukuthembeka Ezindaweni Ezibucayi:
Izixazululo zokuphathwa kokushisa, okuhlanganisa ama-substrate e-metal-core (isb., ama-PCB asekelwe ku-aluminium) kanye nama-vias aqhuba ukushisa, aqinisekisa ukusebenza okuzinzile kwama-amplifier kagesi e-GaN emazingeni okushisa afinyelela ku-150°C. Ukumelana nokudlidliza kanye nokuvikelwa kokugqwala, okuqinisekiswe yizindinganiso ze-IPC-6012 Class 3, kuvumela ukusebenza ngaphansi kwezimo ezinzima njengokushisa okukhulu, i-salt spray, kanye ne-mechanical shock.
