GPS GNSS Helix Antenna for UAV Positioning Handheld Device

Helix Antennas for UAV Positioning Handheld Devices
Helix antennas are typically directional antennas characterized by their spiral structure, which can be classified into two operational modes: axial mode (end-fire) and normal mode. UAV positioning systems predominantly utilize the axial mode due to its high directivity, making it ideal for long-distance communication.

In urban or complex terrain environments, helix antennas leverage their circular polarization properties to:

Reduce multipath interference effects
Enhance signal stability in challenging conditions (e.g., urban canyons)
Improve GPS/BeiDou signal reception accuracy
Mitigate ionospheric delays and multipath errors
Key implementation advantages include:

Lightweight design: Compact spiral structure facilitates integration into portable handheld devices
Operational efficiency: High gain supports extended-range UAV control (>5 km typical)
Real-time performance: Enables low-latency video transmission (e.g., FPV at 720p/60fps with <100 ms latency)
