Right-hand circular polarized dipole antenna for drone telemetry

　　Right-Hand Circular Polarized (RHCP) Dipole Antenna: Reliable Telemetry Solution for Drones

　　In the booming global drone industry—from industrial power line inspection and agricultural crop spraying to emergency rescue and geographic surveying—telemetry systems are the "nerve center" of drone operation, responsible for real-time transmission of flight control signals, sensor data (e.g., HD images, temperature/humidity data), and status feedback. Our Right-Hand Circular Polarized (RHCP) Dipole Antenna is exclusively optimized for drone telemetry scenarios, integrating RHCP’s anti-interference capabilities with the dipole structure’s lightweight and wide-band advantages to ensure stable, long-distance telemetry communication—ideal for global drone manufacturers and telemetry solution providers.

　　1. Core Advantages: Tailored for Drone Telemetry Pain Points

　　① RHCP Polarization: Eliminate Telemetry Signal Interference

　　Anti-Multipath Reflection: Right-hand circular polarization effectively suppresses multipath signals (e.g., reflections from ground, buildings, or water surfaces)—a major cause of telemetry lag or dropout in complex environments (urban canyons, mountainous areas). Ensures 99.9% signal continuity even in dense vegetation or high-rise surroundings.

　　Polarization Matching: Matches the RHCP signal standard of most professional drone telemetry transmitters/receivers (e.g., DJI, Autel, Trimble), minimizing signal attenuation caused by polarization mismatch. Compared to linear polarization antennas, telemetry distance is extended by ≥30% under the same power conditions.

　　Low Axial Ratio (AR): AR ≤1.8dB across the entire working band, ensuring consistent polarization characteristics. Avoids signal distortion during long-distance transmission, critical for high-precision drone operations (e.g., precision agriculture, infrastructure inspection).

　　② Dipole Structure: Lightweight & Easy Integration for Drones

　　Ultra-Lightweight & Compact: Weight as low as 8g, diameter ≤25mm, length ≤80mm—negligible impact on drone payload (perfect for small-to-medium drones with payload limits of 500g+). No need for heavy mounting brackets, reducing drone energy consumption.

　　Low Profile & Flexible Installation: Straight or foldable dipole designs available; can be mounted on drone wings, fuselages, or landing gear via adhesive or screw-on fixtures. Adapts to diverse drone form factors (multicopters, fixed-wing, VTOL drones).

　　Wide-Band Coverage: Supports mainstream drone telemetry frequency bands (2.4GHz: 2400-2483.5MHz; 5.8GHz: 5725-5875MHz) as standard, with optional 915MHz (902-928MHz) for long-range low-power telemetry (e.g., large fixed-wing drones for regional surveying).

　　2. Key Technical Parameters: Meet Drone Telemetry Standards

　　Working Bands: Standard 2.4GHz (2400-2483.5MHz) & 5.8GHz (5725-5875MHz); optional 915MHz (902-928MHz) for long-distance scenarios. Fully compatible with IEEE 802.11n/b/g and drone telemetry protocols (MavLink, DJI SDK).

　　Gain: 2.4GHz: ≥2.5dBi; 5.8GHz: ≥3.0dBi; 915MHz: ≥3.5dBi. Balances signal strength and beamwidth, supporting telemetry distances up to 5km (2.4GHz, line-of-sight) and 8km (915MHz, line-of-sight) for reliable long-range operation.

　　Input Impedance: 50Ω, perfectly matched with drone telemetry modules (e.g., radio transceivers, flight controllers) to reduce signal reflection loss.

　　Environmental Adaptability: Operating temperature -30℃~70℃; waterproof grade IP66 (dustproof, splash-proof); vibration resistance (compliant with MIL-STD-883H, 10-2000Hz) to withstand high-speed flight turbulence and outdoor harsh conditions.

　　Certification: Compliant with CE (EN 300 328), FCC Part 15, and RoHS, ensuring smooth market access in Europe, North America, Asia, and other key regions.

　　3. Application Scenarios: Full Coverage of Drone Telemetry Needs

　　Our RHCP dipole antenna is widely applicable to drone telemetry systems across industries, solving critical communication challenges:

　　Industrial Inspection Drones: Used in power line, wind turbine, and oil pipeline inspection—ensures stable transmission of HD defect images and flight control signals in high-altitude or electromagnetic interference (EMI) environments.

　　Agricultural 植保 Drones: Integrated into crop-spraying drones—supports real-time transmission of soil moisture data and flight path adjustments, even over large farmlands with dense crop cover.

　　Emergency Rescue Drones: Deployed in search-and-rescue missions—maintains telemetry connection in disaster zones (e.g., earthquakes, floods) with broken terrain or debris, enabling real-time delivery of survivor location data.

　　Geographic Surveying Drones: Adapted to fixed-wing survey drones—supports long-distance (8km+) telemetry for large-area topographic mapping, ensuring no data loss during extended flights.

　　Consumer/Commercial Drones: Compatible with professional consumer drones (e.g., aerial photography, mapping)—enhances signal stability in urban or tourist areas with high wireless interference.
