Tasirin kewayon aeriya ta microwaveya dogara da mita mita, riba, da yanayin aikace-aikace. A ƙasa akwai ɓarnawar fasaha don nau'ikan eriya gama gari:
1. Mitar Maɗaukaki & Range Daidaitawa
- E-band E-band (60-90 GHz):
gajeriyar hanya, manyan hanyoyin haɗin gwiwa (1-3 km) don 5G backhaul da comms na soja. Ragewar yanayi ya kai 10 dB/km saboda shanyewar iskar oxygen. - Ka-band Antenna (26.5–40 GHz):
Tauraron dan adam comms ya cimma kilomita 10-50 (ƙasa-zuwa-LEO) tare da 40+ dBi riba. Fade ruwan sama na iya rage kewayon da kashi 30%. - 2.60-3.95 GHzHorn Antenna:
Tsakanin kewayon kewayon (5-20km) don radar da IoT, daidaita shigar ciki da ƙimar bayanai.
2. Nau'in Eriya & Aiki
| Eriya | Riba Na Musamman | Max Range | Amfani Case |
|---|---|---|---|
| Eriya Biconical | 2-6 dBi | <1 km (gwajin EMC) | Binciken gajeriyar hanya |
| Standard Gain Horn | 12-20 dBi | 3-10 km | Calibration/ma'auni |
| Microstrip Array | 15–25 dBi | 5-50 km | 5G tushe tashoshi/Satcom |
3. Mahimman Lissafin Range
Ƙimar ƙimar watsa Friis (*d*):
d = (λ/4π) × √(P_t × G_t × G_r / P_r)
Inda:
P_t = Watsa wuta (misali, radar 10W)
G_t, G_r = Ribar eriya Tx/Rx (misali, ƙaho 20 dBi)
P_r = Hankalin mai karɓa (misali, -90 dBm)
Shawarwari Mai Aiki: Don hanyoyin haɗin tauraron dan adam Ka-band, haɗa ƙaho mai girma (30+ dBi) tare da ƙananan ƙararrawa (NF <1 dB).
4. Iyakar Muhalli
Ragewar ruwan sama: Siginonin Ka-band sun rasa 3-10 dB/km cikin ruwan sama mai yawa.
Yadawar Beam: Tsarin microstrip 25 dBi a 30 GHz yana da nisa na 2.3° - wanda ya dace da madaidaitan hanyoyin mahaɗa-zuwa-aya.
Kammalawa: Matsalolin eriyar Microwave sun bambanta daga <1 km (gwajin EMC na biyu) zuwa 50+ km (Ka-band satcom). Haɓakawa ta zaɓi e-/Ka-band eriya don fitarwa ko ƙaho na 2-4 GHz don dogaro.
