I le fanua o masini eletise eletise, RF antennas ma microwave antennas e masani ona fenumiai, ae o loʻo i ai moni lava eseesega taua. O lenei tusiga o loʻo faʻatautaia suʻesuʻega faʻapolofesa mai itu e tolu: faʻamatalaga faʻaupuga faʻasolosolo, faʻavae mamanu, ma le gaosiga o gaosiga, aemaise lava le tuʻufaʻatasia o tekinolosi autu e pei ovacuum brazing.
RF MISOOgaumu Fa'a'u'u
1. Fa'asologa o fa'aili fa'asolosolo ma uiga fa'aletino
RF antenna:
Ole fa'agaioiga ole fa'agaoioiga ole 300 kHz - 300 GHz, e aofia ai fa'asalalauga galu (535-1605 kHz) i le galu millimeter (30-300 GHz), ae o fa'aoga autu e fa'atumauina ile <6 GHz (pei o le 4G LTE, WiFi 6). Ole umi ole galu (centimita i le mita maualuga), o le fausaga e masani lava o le dipole ma sasa antenna, ma o le lagona i le faapalepale e maualalo (± 1% galu umi e talia).
Antenna microwave:
Aemaise lava 1 GHz - 300 GHz (galu alumini i millimeter galu), fa'aigoa fa'aoga masani e pei ole X-band (8-12 GHz) ma Ka-band (26.5-40 GHz). Ole umi ole galu pupuu (milimita maualuga) mana'oga:
✅ Fa'ato'a sa'o le fa'agasologa o le submilimita (fa'apalepale ≤±0.01λ)
✅ Pulea le talatala o luga (<3μm Ra)
✅ Su'ega dielectric e maualalo le leiloa (ε r ≤2.2, tanδ≤0.001)
2. O le suavai o le gaosiga o tekinolosi
O le faʻatinoga o antenna microwave e faʻalagolago tele i tekinolosi gaosiga maualuga:
| Tekinolosi | RF Antenna | Antenna Microwave |
| Tekinolosi feso'ota'iga | Soldering/Siu fa'amau | Vacuum Brazed |
| Fa'atauga masani | General Electronics Factory | Kamupani Brazing e pei ole Solar Atmospheres |
| Manaoga uelo | Feso'ota'iga fa'atonu | Zero oxygen penetration, toe faʻatulagaina o fatu |
| Fuafuaga Autu | I luga ole tetee <50mΩ | Fa'atatauga fa'aa'asa fa'alautele (ΔCTE<1ppm/℃) |
Le taua autu o le fa'amama gaogao i antenna microwave:
1. Fesoʻotaʻiga e leai se faʻamaʻi: faʻamalosi i totonu ole 10 -5 Torr vacuum environment e aloese ai mai le faʻamaʻiina o faʻamaʻi o Cu / Al ma faʻatumauina le amio> 98% IACS
2. Ave'esea fa'avevela fa'avevela: fa'avevela fa'alili i luga a'e o le sua o mea fa'a'u'u (fa'ata'ita'iga BAISi-4 u'amea, vai 575 ℃) e fa'ate'a ai microcracks.
3. Fa'atonuga fa'aletonu: fa'aletonu atoa <0.1mm/m e fa'amautinoa ai le tumau pea o le vaega ole millimeter.
3. Fa'atusatusaga o fa'atinoga eletise ma fa'ata'ita'iga fa'aoga
Uiga fa'avevela:
1.RF antenna: e masani lava omnidirectional radiation, maua ≤10 dBi
2.Antenna microwave: maualuga le fa'atonuga (lautele 1°-10°), maua le 15-50 dBi
Fa'aoga masani:
| RF Antenna | Antenna Microwave |
| olo leitio FM | Fa'asologa o Array Radar T/R Vaega |
| IoT Sensors | Feso'ota'iga satelite |
| Fa'ailoga RFID | 5G mmWave AAU |
4. Su'ega fa'amaoniga eseesega
RF antenna:
- Taulai: Fa'afetauiga fa'alavelave (VSWR <2.0)
- Metotia: Vector network analyzer salu fa'atele
Antenna microwave:
- Taulai atu: Fa'asologa o le fa'avevela/vaega
- Metotia: Fa'ata'ita'iga o le fanua (sa'o λ/50), su'ega fa'atusatusaga
Fa'ai'uga: RF antennas o le maatulimanu o feso'ota'iga uaea lautele lautele, a'o antenna microwave o le totonugalemu lea o faiga maualuga ma maualuga. O le vai i le va o ia mea e lua:
1. O le fa'atuputeleina o taimi e o'o atu ai i le fa'apu'upu'u o le galu, fa'aoso ai se suiga fa'atusa i le mamanu
2. Suiga fa'agasologa ole gaosiga - fa'alagolago antenna microwave ile fa'atekonolosi fa'apitoa e pei ole fa'amama vacuum e fa'amautinoa ai le fa'atinoga.
3. Fa'ateleina le lavelave o su'ega
Vacuum brazing solutions saunia e kamupani faʻapolofesa faʻapolofesa e pei o Solar Atmospheres ua avea ma faʻamaoniga autu mo le faʻamaoni o faiga o galu millimeter. A'o fa'alautele atu le 6G i le fa'aupuga fa'asolosolo terahertz, o le a sili atu ona iloga le taua o lenei faiga.
Mo nisi fa'amatalaga e uiga i antenna, fa'amolemole asiasi:
