5.8GHz FPV Triple Feed Patch Antenna SMA Directional Circularly Polarized Antenna for FPV RC Drone

Feature: 1. Triple Feed Patch Antenna: The triple feed patch array antenna is a directional circularly polarized antenna optimized based on the original triple feed patch antenna. It uses a set of seven coupled metal patches and better and more expensive high frequency patch, resulting in significantly higher gain. This type of antenna is not suitable for general FPV use because the beam width is quite narrow, but it performs well for long distance flights. 2. Directional Circularly Polarized Antenna: The 5.8GHz triple feed patch antenna is a high performance directional circularly polarized antenna designed by foreign model friends Maarten Baert and Robin Theunis based on the triple feed patch antenna. 3. Excellent Radiation Efficiency: Unlike other FPV patch antennas on fiberglass substrates, there is a significant loss of efficiency in the 5.8G frequency band. Moreover, the feed network losses of many entire antennas are significant. But the design of the coupling patch can reduce the loss of the feed network. 4. 7 Coupled Patch and Excellent Shaft Ratio: This 5.8GHz FPV triple feed patch antenna uses 7 coupled patch, so it can achieve very high gain. Not only perpendicular to the flat plate, but also offset the center point. 5. High Gain: Although the theoretical gain value has not been reached, this is because maximizing gain s to high sidelobes and low axial ratio. 6. Extremely Low Sidelobes: Almost all can be concentrated on the main lobe. Although some gain was sacrificed, the width of the main lobe was increased.
