Ma antenna e microwave anoshandura masaini emagetsi kuita mafungu emagetsi (uye zvinopesana) achishandisa maumbirwo akagadzirwa nemazvo. Kushanda kwawo kunoenderana nepfungwa nhatu huru:
1. Kuchinja kweMafungu eElectromagnetic
Nzira yekutumira:
Masaini eRF anobva kutransmitter anofamba achishandisa mhando dze antenna connector (semuenzaniso, SMA, N-type) kuenda kunzvimbo yekudyisa. Zvinhu zvinofambisa mafungu zve antenna (nyanga/dipoles) zvinoumba mafungu kuita divi remwenje.
Modhi Yokugamuchira:
Mafungu eEM anokonzera mafungu mu antenna, oshandurwa kuita masaini emagetsi emugamuchiri
2. Kudzora Kutungamira & Kudzora Kupenya Kwemwaranzi
Kutungamira kweAntena kunoyera kutarisika kwemwaranzi. Antena ine kutungamira kwepamusoro (semuenzaniso, nyanga) inosimbisa simba muzvikamu zvakamanikana, zvinotongwa ne:
Kutungamira (dBi) ≈ 10 log₁₀(4πA/λ²)
Apo A = nzvimbo yekuvhura, λ = kureba kwehurefu.
Zvigadzirwa zve microwave antenna zvakaita se parabolic dishes zvinosvika >30 dBi directivity ye satellite links.
3. Zvikamu Zvikuru & Mabasa Azvo
| Chikamu | Basa | Muenzaniso |
|---|---|---|
| Chinhu Chinopenya | Inoshandura simba remagetsi-EM | Chigamba, dipole, slot |
| Network yekupa zvekudya | Mafungu anotungamirwa ane kurasikirwa kushoma | Mugwagwa wewaveguide, mutsetse we microstrip |
| Zvikamu Zvisingashande | Simbisa kuvimbika kwechiratidzo | Ma phase shifters, ma polarizers |
| Zvinobatanidza | Chinongedzo netambo dzekutumira | 2.92mm (40GHz), 7/16 (High Pwr) |
4. Dhizaini Yakanangana Nemafrequency
< 6 GHz: Ma antenna e microstrip ndiwo anotonga pane saizi diki.
> 18 GHz: Horn dzeWaveguide dzinoshanda zvakanaka pakuita basa rakaderera.
Chinhu Chinokosha: Kufananidza Impedance pa antenna connectors kunodzivirira kupenya (VSWR <1.5).
Mashandisirwo Ezvinhu Chaizvo:
5G Massive MIMO: Microstrip arrays ine zvikamu zvisingashande zvekutungamira danda.
Masisitimu eRadar: Kutungamira kwakakwirira kweantenna kunoita kuti pave nekutevedza kwakarurama kwechinangwa.
Satellite Comms: Parabolic reflectors dzinoita kuti aperture ishande zvakanaka ne99%.
Mhedziso: Ma antenna e microwave anoshandisa electromagnetic resonance, mhando dze antenna connector dzakarongeka, uye optimized antenna directionivity kuti atumire/agamuchire masaini. Zvigadzirwa zve antenna zve microwave zvemhando yepamusoro zvinosanganisa zvinhu zvisingashande kuti zvideredze kurasikirwa uye kuwedzera kugona.
Kuti udzidze zvakawanda nezve antenna, ndapota shanyira:
Nguva yekutumira: Nyamavhuvhu-15-2025
