GEPRC Triple Feed Patch Array 5.8GHz 14dBi Patch Antenna (SMA)

Brand: GEPRC. The compact and high-performance GEPRC Triple Feed patch antenna is designed for reliable video signal reception in the 5.8 GHz band and is optimal for use in drones and FPV systems. The triple-feed design allows it to work with both right-hand (RHCP) and left-hand (LHCP) circular polarization: by changing the SMA connector's connection point, you simply switch polarization and improve reception quality depending on flight conditions.

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: < 1.3
• Antenna Gain: 14 dBi
• Half-Power Beamwidth: 55° (horizontal and vertical)
• Radiation Efficiency: 83.5%

The characteristic values are obtained based on simulations, but practical measurements are very close to the predicted parameters, making the antenna suitable for stable video stream reception at distances typical for FPV flights. Thanks to its increased gain of 14 dBi and wide bandwidth, the device provides clearer and longer-range reception compared to standard omnidirectional antennas.

It is important to note that due to differences in the dielectric constant of FR4 material, the center frequency may shift slightly between production batches; a shift of up to 100 MHz is considered normal and is not a product defect.

Package Contents:

• 1 pc. x GEPRC Triple Feed Patch Antenna
• 1 pc. x RPSMA Plug - RPSMA Plug Cable
• 1 pc. x Case

The antenna is compatible with typical SMA/RPSMA connectors and easily integrates into antenna-cable kits for drones. The polarization-switchable (RHCP/LHCP) design helps reduce losses from polarization mismatch between the transmitter and receiver, improving video link stability. The device is suitable for both FPV enthusiasts and professional pilots who need a reliable solution for 5.8 GHz video reception with high gain and good efficiency.
