GEPRC Triple Feed Patch Array RP-SMA FPV Goggle Antenna

Introduction

The GEPRC Triple Feed Patch Array Antenna is a high-performance directional, circularly polarized antenna based on the original Triple Feed Patch design. It utilizes an advanced array of seven coupled patches, resulting in significantly higher gain compared to standard antennas. While its narrower beamwidth is specifically optimized for long-range FPV flights, it provides exceptional signal clarity and stability for pilots pushing the boundaries of their flights.

Key advantages

• Superior radiation performance with minimal loss, thanks to the use of coupled patches to simplify the power dividing network.
• Excellent axial ratio, ensuring a strong signal not just directly ahead but also off-axis.
• High gain (14.4 dBi) concentrated into the main lobe for maximum signal strength.
• Very low side lobes, focusing energy efficiently and enhancing the main beam's effectiveness.
• Optimized for long-range FPV flights, providing stable and clear video transmission over extended distances.
• Durable construction with a 150mm diameter dish.
• RP-SMA connector for broad compatibility with FPV goggles.

Technical specifications

• Center Frequency: 5.8 GHz
• Bandwidth: 660 MHz (5.47 - 6.13 GHz)
• Matching: S11 < -20 dB, VSWR < 1.22 (at center frequency)
• Axial Ratio: < 1.1
• Antenna Gain: 14.4 dBi
• Connector: RP-SMA/SMA
• Beamwidth at Half Power: 30° (Horizontal & Vertical)
• Radiation Efficiency: 75%
• Large Dish Diameter: 150 mm

Applications

This antenna is perfectly suited for FPV drone pilots focused on long-range flying, drone racing where signal integrity is crucial, and any application requiring a focused, high-gain directional antenna for the 5.8 GHz band. It's an excellent upgrade for improving video link performance on FPV goggles.

Compatibility

Features an RP-SMA connector, compatible with most FPV goggles and video transmitters that use this standard. For SMA-compatible devices, an adapter may be required.

FAQ

What is the main advantage of the GEPRC Triple Feed Patch Array Antenna?

The main advantage is its significantly higher gain (14.4 dBi) and focused beamwidth, making it ideal for achieving stable, long-range FPV flights. It offers superior signal clarity and performance over extended distances compared to omnidirectional antennas.

Is this GEPRC antenna suitable for general FPV flying or specifically for long-range?

This antenna is specifically designed and recommended for long-range FPV flights due to its focused beamwidth. While it offers excellent performance, its directional nature might be less forgiving for general, close-range FPV flying compared to wider-beam antennas.
