Description

The Triple Feed Patch 5.8GHz Antenna utilizes a specialized triple-feed design to achieve a stable circular polarization pattern and high radiation efficiency at 5.8GHz. This design mitigates the signal loss typically associated with standard FR4 PCB material, resulting in stronger, cleaner video transmission for both analog and digital HD FPV systems.

Engineered for directional use, this antenna provides focused gain to extend range and improve signal penetration when pointed toward the drone. Its robust axial ratio performance ensures reliable signal reception not only directly in front of the antenna but also at off-center angles, making it suitable for ground station and fixed receiver setups.

Key Features

  • High-Efficiency Design: Engineered to overcome the inherent high-frequency losses of standard FR4 PCB substrates.
  • Stable Circular Polarization: Triple-feed network ensures a consistent axial ratio below 1.3 for reduced multipath interference.
  • Directional High Gain: 9.4 dBi focused beam pattern maximizes signal strength and penetration for long-range FPV.
  • Broad Compatibility: 660 MHz bandwidth covers the entire 5.8GHz FPV band, supporting analog, DJI FPV, Walksnail, and HDZero systems.
  • Durable Construction: Solid PCB-based patch antenna housed in a protective casing for reliable field use.
  • Standard Connector: Integrated RP-SMA male connector ensures direct plug-and-play compatibility with common FPV equipment.

Applications

  • Fixed ground station receiver for long-range analog or digital HD FPV exploration.
  • Directional antenna upgrade for FPV goggles to improve signal clarity and penetration in noisy RF environments.
  • Base station antenna for drone racing events to provide clean, dedicated video feed to spectators.
  • Relay station setup for extending the control and video range of UAV mapping and inspection platforms.

Frequently Asked Questions

What FPV systems is this 5.8GHz patch antenna compatible with?

This antenna is compatible with any 5.8GHz FPV system. Its wide 660 MHz bandwidth covers the entire 5.8GHz band, making it suitable for analog video transmitters, DJI Digital FPV Air Units, Walksnail Avatar, and HDZero video systems. Ensure your equipment uses an RP-SMA female port.

How do I mount and orient this directional patch antenna?

As a directional antenna, it must be pointed toward your drone for optimal performance. Mount it on a tripod or fixed mast for ground station use, or securely attach it to your FPV goggles. The flat face of the patch should be aimed at your flight area. For best results, use it in conjunction with an omnidirectional antenna on your receiver for diversity.

What is the advantage of the triple-feed design and a low axial ratio?

The triple-feed design creates a more uniform circular polarization field, resulting in a stable axial ratio below 1.3. This means the antenna maintains its polarization purity over a wider angle off its central axis, reducing signal nulls and multipath interference. This leads to more consistent video quality even when the drone is not perfectly aligned with the antenna.
