GEPRC Triple Feed Patch Array 5.8GHz 14dBi Antenna – SMA

GEPRC 5.8GHz Patch Antenna – Triple Feed 14dBi Directional Array

The GEPRC 5.8GHz Patch Antenna delivers focused directional performance for long-range FPV operations. This triple feed array design concentrates signal energy into a forward beam instead of spreading it in all directions. As a result, pilots achieve stronger signal penetration, improved range stability, and reduced interference during extended flights.

The antenna uses a seven-element coupled patch configuration. This structure minimizes feed network losses and improves radiation efficiency. By simplifying the internal feed layout, the design maintains stronger signal integrity at 5.8GHz.

GEPRC 5.8GHz Patch Antenna Directional Radiation Pattern

This antenna maintains a 30° half-power beam width in both horizontal and vertical planes. The narrow beam focuses energy directly toward the aircraft. Pilots using ground station setups benefit from improved reception during long-distance missions. Because the beam remains concentrated, this antenna works best for forward-facing long-range flights rather than freestyle flying.

High Gain Performance of GEPRC 5.8GHz Patch Antenna

The antenna produces approximately 14.4dBi gain at 5.8GHz. It achieves around 75% radiation efficiency, allowing strong signal output across the operating band. The axial ratio stays below 1.1, which maintains clean circular polarization performance. Low S11 values and stable VSWR levels confirm strong impedance matching and reduced signal reflection.

Wide 5.8GHz Operating Bandwidth

The antenna supports a bandwidth of 660 MHz (5.47–6.13 GHz). This range ensures compatibility with standard 5.8GHz FPV video transmission systems. For optimized long-range setups, many pilots combine it with circular polarized antennas such as the iFlight Albatross 150mm V2 5.8Ghz Antenna RHCP SMA or the FPV Drone Mushroom Antenna 4.8–6.1GHz High Gain SMA to maintain consistent polarization matching.

Durable 150mm Structural Design

The 150mm disk structure provides mechanical stability and consistent radiation control. The FR4 material supports high-frequency operation while maintaining structural rigidity. The antenna design reduces side lobes and directs energy toward the primary beam, improving long-range precision.
