Emkhakheni wamadivayisi emisebe kagesi, ama-antenna e-RF nama-antenna e-microwave avame ukudideka, kodwa empeleni kukhona umehluko oyisisekelo. Lesi sihloko senza ukuhlaziywa kobungcweti kusuka ezicini ezintathu: incazelo yebhendi yemvamisa, isimiso sokuklama, kanye nenqubo yokukhiqiza, ikakhulukazi ukuhlanganisa ubuchwepheshe obubalulekile obufana noi-vacuum brazing.
I-RF MISOIsithando Sokushisisa Umshini
1. Ububanzi bebhendi yemvamisa kanye nezici zomzimba
I-antenna ye-RF:
Ibhendi yemvamisa yokusebenza ingu-300 kHz - 300 GHz, ehlanganisa ukusakazwa kwamagagasi aphakathi nendawo (535-1605 kHz) kuya kumagagasi e-millimeter (30-300 GHz), kodwa izinhlelo zokusebenza eziyinhloko zigxile ku-< 6 GHz (njenge-4G LTE, i-WiFi 6). Ububanzi bobude bude (isentimitha kuya ezingeni lemitha), isakhiwo ikakhulukazi siyi-dipole ne-whip antenna, futhi ukuzwela kokubekezelelana kuphansi (±1% ubude bobude buyamukeleka).
I-antenna ye-microwave:
Ngokukhethekile i-1 GHz - 300 GHz (i-microwave kuya ku-millimeter wave), amabhendi emvamisa yokusetshenziswa ajwayelekile njenge-X-band (8-12 GHz) kanye ne-Ka-band (26.5-40 GHz). Izidingo zobude obufushane (izinga le-millimeter):
✅ Ukunemba kokucubungula kwezinga le-Submillimeter (ukubekezelelana ≤±0.01λ)
✅ Ukulawula ukurhabaxa kobuso okuqinile (< 3μm Ra)
✅ I-substrate ye-dielectric elahlekelwa kancane (ε r ≤2.2, tanδ≤0.001)
2. Umthombo wobuchwepheshe bokukhiqiza
Ukusebenza kwama-antenna e-microwave kuncike kakhulu kubuchwepheshe bokukhiqiza obusezingeni eliphezulu:
| Ubuchwepheshe | I-antenna ye-RF | I-Antenna ye-Microwave |
| Ubuchwepheshe bokuxhuma | Ukubopha nge-Soldering/Screw | I-Vacuum Braced |
| Abahlinzeki Abajwayelekile | Ifektri Yezinto Ezisebenza Ngogesi Ezijwayelekile | Izinkampani Zokubumba Ezifana Ne-Solar Atmospheres |
| Izidingo zokushisela | Uxhumano oluqhubayo | Ukungena kwe-oxygen okungelutho, ukuhlelwa kabusha kwesakhiwo sezinhlamvu |
| Amamethrikhi Ayisihluthulelo | Ukumelana okusebenzayo <50mΩ | Ukufaniswa kwe-coefficient yokwandisa ukushisa (ΔCTE<1ppm/℃) |
Inani eliyinhloko le-vacuum brazing kuma-antenna e-microwave:
1. Ukuxhumeka okungena-oxidation: ukubhoboza endaweni yokushaja engu-10 -5 Torr ukuze kugwenywe ukushaja kwe-Cu/Al alloys nokugcina ugesi ohambayo >98% IACS
2. Ukususwa kokucindezeleka kokushisa: ukushisa kwe-gradient kuya ngaphezu koketshezi lwezinto zokubopha (isb. i-BAISi-4 alloy, i-liquidus 575℃) ukuze kususwe imifantu emincane
3. Ukulawulwa kokuguquguquka: ukuguqulwa okuphelele <0.1mm/m ukuqinisekisa ukuhambisana kwesigaba samagagasi se-millimeter
3. Ukuqhathaniswa kokusebenza kukagesi kanye nezimo zokusetshenziswa
Izici zemisebe:
1.I-antenna ye-RF: imisebe eqondiswe kuyo yonke indawo, inzuzo ≤10 dBi
2.I-antenna ye-microwave: eqondisa kakhulu (ububanzi bomsebe 1°-10°), thola i-15-50 dBi
Izinhlelo zokusebenza ezijwayelekile:
| I-antenna ye-RF | I-Antenna ye-Microwave |
| Umbhoshongo womsakazo we-FM | Izingxenye ze-T/R ze-Radar ye-Phased Array |
| Izinzwa ze-IoT | Okuphakelayo kokuxhumana kwesathelayithi |
| Amathegi e-RFID | I-5G mmWave AAU |
4. Umehluko wokuqinisekisa ukuhlolwa
I-antenna ye-RF:
- Ukugxila: Ukufanisa i-Impedance (VSWR < 2.0)
- Indlela: Ukushaqeka kwemvamisa yokuhlaziya inethiwekhi ye-Vector
I-antenna ye-microwave:
- Ukugxila: Iphethini yemisebe/ukuvumelana kwesigaba
- Indlela: Ukuskena okuseduze kwensimu (ukunemba λ/50), ukuhlolwa kwensimu ehlanganisiwe
Isiphetho: Ama-antenna e-RF ayitshe lesisekelo lokuxhumana okungenantambo okuvamile, kuyilapho ama-antenna e-microwave eyitshe lesisekelo sezinhlelo ezisebenzisa imvamisa ephezulu kanye nokunemba okuphezulu. Iphuzu eliphakathi kwalokhu okubili yileli:
1. Ukwanda kwemvamisa kuholela ekufinyezweni kobude besikhathi, okubangela ushintsho olubonakalayo ekwakhiweni
2. Ushintsho lwenqubo yokukhiqiza - ama-antenna e-microwave athembele kubuchwepheshe obusezingeni eliphezulu njengokufaka i-vacuum brazing ukuqinisekisa ukusebenza kahle
3. Ubunzima bokuhlola bukhula ngokushesha okukhulu
Izixazululo ze-vacuum brazing ezinikezwa yizinkampani zobungcweti ze-brazing ezifana ne-Solar Atmospheres sezibe yisiqinisekiso esibalulekile sokuthembeka kwezinhlelo zamagagasi e-millimeter. Njengoba i-6G ikhula iye kubhendi yemvamisa ye-terahertz, inani lale nqubo lizobonakala kakhulu.
Ukuze ufunde kabanzi ngama-antenna, sicela uvakashele:
