Anteenooyinka Microwave-ku waxay calaamadaha korontadu u beddelaan hirarka korantada (iyo beddelkeeda) iyagoo isticmaalaya qaab-dhismeed sax ah. Hawlgalkoodu waxa uu ku xidhan yahay saddex mabaadi'da asaasiga ah:
1. Isbeddelka Wave Electromagnetic
Qaabka Gudbinta:
Calaamadaha RF ee ka yimaada gudbiyaha safarka iyada oo loo marayo noocyada isku xirka anteenada (tusaale, SMA, nooca N) ilaa barta quudinta. Curiyayaasha anteenadu (geesaha/dipoles) waxay u qaabeeyaan mawjadaha si ay u noqdaan alwaax jihaysan.
Qaabka Qaadashada:
Dhacdada mowjadaha EM waxay kiciyaan qulqulka anteenada, oo dib loogu rogo calaamadaha korantada ee qaataha
2. Jihaynta & Xakamaynta Shucaaca
Toosinta anteenada ayaa qiyaaseysa diirada beam. Anteenada jihaynta sare (tusaale, gees) waxa ay tamarta ku ururisaa lugaha cidhiidhiga ah, oo ay maamusho:
Jihaynta (dBi) ≈ 10 log₁₀(4πA/λ²)
Halka A = aagga daloolka, λ = dhererka hirarka.
Alaabooyinka anteenada Microwave sida suxuunta parabolic waxay gaarayaan> 30 dBi jiheynta isku xirka satalaytka.
3. Qaybaha Muhiimka ah & Doorarkooda
| Qayb | Shaqada | Tusaale |
|---|---|---|
| Curiyaha Shucaaca | Beddela koronto-EM tamarta | Patch, dipole, Afyare |
| Shabakadda Quudinta | Hagaya hirarka khasaaraha ugu yar | Waveguide, khadka microstrip |
| Qaybaha dadban | Kor u qaad daacadnimada calaamadaha | Marxalada wareega, polarizers |
| Xidhiidhiyayaasha | Interface leh xadhkaha gudbinta | 2.92mm (40GHz), 7/16 (Pwr Sare) |
4. Soo noqnoqoshada-Naqshad Gaar ah
<6 GHz: anteenooyinka Microstrip waxay u badan yihiin cabbirka is haysta.
> 18 GHz: geesaha Waveguide waxay aad ugu fiican yihiin waxqabadka khasaaraha hooseeya.
Arrin Halis ah: Isbarbardhigga isku xirka anteenada waxay ka hortagtaa milicsiga (VSWR <1.5).
Codsiyada Adduunka-dhabta ah:
5G Massive MIMO: Qalabka Microstrip oo leh qaybo dadban oo loogu talagalay isteerinka iftiinka.
Nidaamyada Radar: toosinta sare ee anteenada waxay hubisaa raadinta saxda ah ee bartilmaameedka.
Comms Satellite: Miliciyeyaasha Parabolic waxay gaadhaan 99% hufnaanta daloolka.
Gabagabo: Anteenooyinka Microwave waxay ku tiirsan yihiin resonance electromagnetic, noocyada isku xidhka anteenooyinka saxda ah, iyo habaynta anteenada la wanaajiyay si loo gudbiyo/helo calaamadaha. Alaabooyinka anteenada microwave-ga horumarsan waxay isku daraan qaybo aan fiicneyn si loo yareeyo khasaaraha oo loo kordhiyo tirada.
