GEPRC Triple Feed Patch Array SMA FPV Goggle Antenna 14.4 dBi High Gain

Introduction

The GEPRC Triple Feed Patch Array SMA Antenna is a cutting-edge directional, circularly polarized antenna designed for demanding FPV and long-range UAV applications. Building upon the original Triple Feed Patch design, this array utilizes seven coupled patches to achieve significantly higher gain, delivering a more focused and powerful signal for extended flight operations. While its narrow beamwidth makes it less suitable for general FPV use, it excels in scenarios requiring maximum signal integrity over long distances.

Key Advantages

• Exceptional Radiation Efficiency: Engineered with coupled patches to minimize power dividing network losses, overcoming common FR4 material losses at 5.8 GHz.
• Superior Axial Ratio: Delivers an excellent axial ratio, ensuring robust signal performance not just directly perpendicular to the patch but also off-axis.
• High Gain Performance: Achieves a high gain of 14.4 dBi, focusing signal energy efficiently for enhanced range.
• Minimized Side Lobes: Features very low side lobes, concentrating almost all energy into the main lobe for a cleaner, stronger signal.
• Optimized Beamwidth: While the beamwidth is focused, it's optimized to enhance gain and signal concentration for long-range flights.
• Durable Construction: Built with quality materials for reliable performance in various conditions.
• Versatile Connector: Equipped with both RP-SMA and SMA connectors for broad compatibility.
• Enhanced Signal Clarity: Reduces interference and signal degradation, crucial for critical long-range missions.
