Antenna Classification in UAV Wireless Video Transmission

In UAV wireless video transmission and telemetry systems, antennas play a critical role in determining transmission distance, signal stability, anti-interference performance, e affidabilità complessiva. Antennas can be classified based on different standards:

---

1. By Radiation Pattern

• Omnidirectional Antennas

  • Radiate signals evenly in 360° on the horizontal plane.

  • Vantaggio: Maintain stable links while the UAV is moving and changing orientation.

  • Common Use: UAV airborne side, handheld ground controllers.

  • Esempi: Whip antennas, fiberglass omnidirectional antennas.

• Antenne direzionali

  • Concentrate energy in a specific direction for higher gain and longer transmission range.

  • Vantaggio: Excellent for long-distance transmission and point-to-point communication.

  • Drawback: Require alignment toward the UAV.

  • Common Use: Ground stations and fixed receivers.

  • Esempi: Yagi antennas, panel antennas, parabolic antennas.

---

2. By Application Scenario (Deployment Location)

• Airborne UAV Antennas

  • Leggero, compatto, resistente alle vibrazioni, often omnidirectional to ensure stable connectivity in flight.

  • Esempi: Small whip antennas, patch antennas, embedded PCB antennas.

• Ground Station Antennas

  • Less weight restriction, can use large high-gain directional antennas to extend transmission distance.

  • Esempi: Yagi antennas, fiberglass antennas, high-gain panel antennas.

---

3. By Structure and Design

• Fiberglass Antennas

  • Encased in fiberglass for waterproofing, wind resistance, and corrosion protection.

  • Often omnidirectional, suitable for outdoor fixed stations or vehicle-mounted bases.

• Antenne Yagi

  • Classic directional antennas with gain up to 8–15 dBi.

  • Ideal for long-range UAV video reception at ground stations.

• Whip Antennas

  • Sottile, rod-shaped, typically omnidirectional.

  • Rugged and durable, used for vehicle-mounted ground stations.

• Patch Antennas

  • Compatto, leggero, easy to integrate into UAV fuselage or electronics.

  • Suitable for onboard applications with short to medium-range communication.

---

4. By Operating Frequency

• 2.4 GHz Antennas: Common for UAV remote control signals and short-range WiFi-based video links.

• 5.8 GHz Antennas: Popular for HD video transmission with higher bandwidth, though weaker in penetration.

• 900 MHz / 1.2 GHz Antennas: Effective for long-range control and video, with stronger anti-obstacle performance.

• 700–800 MHz Antennas: Widely used in COFDM/OFDM video links for long-range and strong penetration capability.

---

5. By Polarization

• Linear Polarization: Typical for whip antennas and Yagi antennas.

• Circular Polarization: Reduces signal fading caused by UAV attitude changes, common in FPV video systems.

---

Riepilogo
Nella trasmissione wireless UAV, antenna selection depends on:

• Deployment location (airborne vs. terra),

• Distanza di trasmissione (short/medium vs. a lungo raggio),

• Ambiente (urban, rurale, montuoso),

• Mobility (fixed ground base vs. vehicle-mounted).

• Airborne UAV → Lightweight omnidirectional whip or patch antennas.

• Fixed Ground Station → High-gain Yagi or panel directional antennas.

• Vehicle Ground Station → Fiberglass omnidirectional or whip antennas.
