Ole tulaga lelei ole aantenne microwavee fa'alagolago i lona fa'alava fa'alava, maua, ma fa'ata'ita'iga fa'aoga. O lo'o i lalo se fa'aletonu fa'apitoa mo ituaiga antenna masani:
1. Feso'ota'iga Fa'aili Fa'alava & Va'aiga
- Antenna E-band (60–90 GHz):
So'oga pupu'u, maualuga (1-3 km) mo le 5G backhaul ma feso'ota'iga a le militeri. E oʻo i le 10 dB/km le faʻaitiitia o le ea ona o le faʻaogaina o le okesene. - Ka-band Antenna (26.5–40 GHz):
O feso'ota'iga satelite e ausia le 10–50 km (le-le-LEO) ma le 40+ dBi maua. E mafai ona fa'aitiitia timuga i le 30%. - 2.60–3.95 GHzAntenna Puu:
O le vaeluaga o le vaeluaga (5-20 km) mo le radar ma le IoT, faapaleni le faʻaogaina ma le fua o faʻamaumauga.
2. Ituaiga Antenna & Fa'atinoga
| Antenna | Manuia masani | Avanoa Max | Fa'aoga Tulaga |
|---|---|---|---|
| Biconical Antenna | 2–6 dBi | <1 kilomita (su'ega EMC) | Su'esu'ega pupuu |
| Standard Gain Horn | 12–20 dBi | 3–10 kilomita | Fa'avasegaina/fua |
| Microstrip Array | 15–25 dBi | 5–50 kilomita | 5G nofoaga autu/Satcom |
3. Fa'avae Fa'atatau o Va'aiga
Ole fua ole fa'asologa ole Friis (*d*):
d = (λ/4π) × √(P_t × G_t × G_r / P_r)
O fea:
P_t = Lafo le mana (fa'ata'ita'iga, 10W radar)
G_t, G_r = Tx/Rx antenna maua (fa'ata'ita'iga, 20 dBi pu)
P_r = Ma'ale'ale o le tagata e mauaina (fa'ata'ita'iga, –90 dBm)
Fautuaga Fa'ata'ita'i: Mo feso'ota'iga satelite Ka-band, fai fa'alua se pu maualuga (30+ dBi) fa'atasi ai ma fa'amalo leo maualalo (NF <1 dB).
4. Tapulaa o le Siosiomaga
Fa'atiga o timuga: E leiloa le 3–10 dB/km ile timuga mamafa.
Fa'asalalauina Beam: O le 25 dBi microstrip array i le 30 GHz ei ai le 2.3 ° beamwidth - talafeagai mo feso'ota'iga sa'o i lea itu-i-itu.
Fa'ai'uga: O laina antenna microwave e eseese mai <1 km (su'ega EMC biconical) i le 50+ km (Ka-band satcom). Fa'alelei e ala i le filifilia o antenna E-/Ka-band mo le gaosiga po'o le 2-4 GHz pu mo le fa'amaoni.
Mo nisi fa'amatalaga e uiga i antenna, fa'amolemole asiasi:
