Dhinaca qalabka shucaaca elektromagnetic-ka, anteenooyinka RF iyo anteenooyinka microwave-ka badanaa waa la isku qaldaa, laakiin dhab ahaantii waxaa jira kala duwanaansho aasaasi ah. Maqaalkani wuxuu sameeyaa falanqayn xirfadeed oo ka kooban saddex cabbir: qeexidda heerka soo noqnoqda, mabda'a naqshadeynta, iyo habka wax soo saarka, gaar ahaan isku darka teknoolojiyada muhiimka ah sidadab-shidka faakiyuumka.
RF MISOFoornada Daadinta Faakuumka
1. Kala duwanaanshaha heerka soo noqnoqoshada iyo astaamaha jireed
Anteenada RF:
Xariiqda soo noqnoqoshada hawlgalka waa 300 kHz - 300 GHz, oo daboolaysa baahinta hirarka dhexdhexaadka ah (535-1605 kHz) ilaa hirarka millimeter (30-300 GHz), laakiin codsiyada asaasiga ah waxay ku urursan yihiin < 6 GHz (sida 4G LTE, WiFi 6). Mowjadu way dheer tahay (sentimitir ilaa heerka mitirka), qaab-dhismeedku wuxuu inta badan yahay anteeno dipole iyo whip ah, xasaasiyadda dulqaadkuna waa hooseysaa (±1% mowjadda hirarka waa la aqbali karaa).
Anteenada Microwave-ka:
Gaar ahaan 1 GHz - 300 GHz (mawjadda microwave ilaa milimitir), xargaha soo noqnoqda ee codsiyada caadiga ah sida X-band (8-12 GHz) iyo Ka-band (26.5-40 GHz). Shuruudaha hirarka gaaban (heerka milimitir):
✅ Saxnaanta habaynta heerka submillimeter-ka (dulqaad ≤±0.01λ)
✅ Xakamaynta qallafsanaanta dusha sare (< 3μm Ra)
✅ Substrate dielectric ah oo lumis yar leh (ε r ≤2.2, tanδ≤0.001)
2. Biyaha ugu muhiimsan ee tiknoolajiyada wax soo saarka
Waxqabadka anteenooyinka microwave-ka waxay aad ugu xiran yihiin tiknoolajiyada wax soo saarka ee heerka sare ah:
| Teknolojiyad | Anteenada RF | Anteenada Microwave-ka |
| Tiknoolajiyada isku xirka | Xidhitaanka/Boorno-xidhka | Faakiyuum lagu shubay |
| Alaab-qeybiyeyaasha Caadiga ah | Warshadda Elektarooniga Guud | Shirkadaha Nalalka Dabiiciga ah sida Jawiga Qorraxda |
| Shuruudaha alxanka | Xidhiidhka gudbiyaha | Gelitaan la'aan oksijiin, dib-u-habeyn qaab-dhismeedka hadhuudhka |
| Halbeegyada Muhiimka ah | Iska caabinta <50mΩ | Isbarbardhigga isku-dhafka ballaarinta kulaylka (ΔCTE <1ppm/℃) |
Qiimaha asaasiga ah ee nadiifinta faakuumka ee anteenooyinka microwave-ka:
1. Isku xirka aan oksaydhku ku jirin: ku shubista jawi faakiyuum ah oo 10 -5 Torr ah si looga fogaado oksaydheynta walxaha Cu/Al iyo ilaalinta socodka >98% IACS
2. Ka saarista cadaadiska kulaylka: kululaynta heerka ilaa dareeraha ka sarreeya walaxda birta lagu shubo (tusaale ahaan daawaha BAISi-4, dareeraha dareeraha ah 575℃) si loo baabi'iyo burburka yar yar
3. Xakamaynta isbeddelka: isbeddelka guud <0.1mm/m si loo hubiyo isku dheelitirka marxaladda hirarka milimitir
3. Isbarbardhigga waxqabadka korantada iyo xaaladaha codsiga
Astaamaha shucaaca:
1.Anteenada RF: inta badan shucaaca jihada oo dhan, faa'iido ≤10 dBi
2.Anteenada Microwave-ka: Jiho sare (ballaca alwaaxa 1°-10°), waxay kordhisaa 15-50 dBi
Codsiyada caadiga ah:
| Anteenada RF | Anteenada Microwave-ka |
| Munaaradda raadiyaha FM | Qaybaha T/R ee Radar Array ee Wajiga ah |
| Dareemayaasha IoT | Quudinta isgaarsiinta dayax-gacmeedka |
| Calaamadaha RFID | 5G mmMowjad AAU |
4. Kala duwanaanshaha xaqiijinta tijaabada
Anteenada RF:
- Diiradda: Iswaafajinta Impedance (VSWR < 2.0)
- Habka: Falanqaynta shabakadda Vector-ka ee soo noqnoqda
Anteenada Microwave-ka:
- Diiradda: Qaab-dhismeedka shucaaca/joogteynta wejiga
- Habka: Sawir-qaadista goobta u dhow (saxnaanta λ/50), tijaabada goobta ee is haysta
Gunaanad: Anteenooyinka RF waa aasaaska isku xirka wireless-ka guud, halka anteenooyinka microwave-ka ay yihiin xudunta nidaamyada soo noqnoqda sare iyo kuwa saxnaanta sare leh. Meesha u dhaxaysa labada waa:
1. Kordhinta soo noqnoqoshada waxay horseedaa hirar gaaban, taasoo kicinaysa isbeddel qaab-dhismeed ah oo ku yimaada naqshadda
2. Kala-guurka habka wax-soo-saarka - anteenooyinka microwave-ka waxay ku tiirsan yihiin teknoolojiyada casriga ah sida nadiifinta faakiyuumka si loo hubiyo waxqabadka
3. Kakanaanta imtixaanku si aad ah ayay u koraysaa
Xalalka nadiifinta faakuumka ee ay bixiyaan shirkadaha xirfadlayaasha ah ee nadiifinta sida Atmospheres-ka Qorraxda ayaa noqday dammaanad muhiim ah oo lagu kalsoonaan karo nidaamyada hirarka millimeter-ka. Marka 6G ay ku fiddo xadka soo noqnoqda ee terahertz, qiimaha habkan ayaa noqon doona mid aad u muuqda.
