5.8GHz Triple Feed Patch Antenna 9.4dBi High Accuracy Directional Circularly Polarized Antenna for FPV Racing Drone

Feature: 1. [Professional] Triple feed patch antenna is a directional circular polarization antenna optimized based on the original triple feed patch antenna. It uses a set of seven coupled metal sheets and better high frequency plates to get higher gain. 2. [Application] This triple feed patch antenna is not suitable for general for FPV use, because the beamwidth is quite narrow, but it performs well for long range flights. High accuracy, even amateurs can use it. 3. [Loss Reduction] Excellent radiation efficiency. Unlike other flat antennas with glass fiber substrate, it has serious efficiency loss for 5.8G band. The design of coupling plate can make the feed network loss reduced. 4. [Excellent Axial Ratio] For FPV drone triple feed patch antenna with excellent axial ratio, the axial ratio is less than 1.3, not only perpendicular to the flat plate, and offset the center point. 5. [High Gain] This directional circularly polarized antenna has high gain, although not to the theoretical gain value, because maximizing gain results in high side flap and low axial ratio.
