The Triple Feed Patch Array antenna is a premier directional circularly polarized antenna, designed as an advanced evolution of the original Triple Feed Patch. By incorporating an array of seven coupled patches, this antenna delivers significantly higher gain, making it an excellent choice for long-range FPV (First Person View) flying. While its relatively narrow beam width may not be ideal for general FPV use, it excels in focused, long-distance communication.
Key Features
- Superior Radiation Efficiency: Unlike most FR4-based patch antennas, which typically struggle with efficiency at 5.8 GHz due to the lossy nature of FR4, our design minimizes these losses by utilizing coupled patches. This simplification of the feed network ensures exceptional efficiency.
- Outstanding Axial Ratio: The Triple Feed Patch Array boasts an exceptionally good axial ratio, not only directly perpendicular to the patch but also off-center. This guarantees consistent, high-quality performance across a broader area.
- Optimized Gain: This antenna is designed to achieve high gain without the drawbacks of high sidelobes, which can degrade performance. By balancing gain with a low axial ratio, the energy is concentrated in a broad and effective main lobe, making the antenna more reliable for long-distance flights.
- Minimal Sidelobes: Nearly all the energy is focused into the main lobe, which enhances the width and effectiveness of the primary beam, further increasing the antenna’s reliability for long-range communication.
- Guaranteed Performance: Our Triple Feed Patch Array antennas are produced with the highest precision and undergo multiple tests on a Vector Network Analyzer (VNA) to ensure optimal performance within the specified frequency range. We guarantee that every antenna we produce will exhibit the best possible characteristics, making it arguably the best Triple Feed Patch Array on the market.
