Feature(may vary by option.)

●The FPV triple transport patch antenna is a directional circularly polarized antenna.
●Good radiation efficiency.
●Most FR4-based patches have terrible efficiency because FR4 is very lossy at 5.8 GHz.
●Good axial ratio, not only directly perpendicular to the patch but also off-center.
●Cheap and easy to manufacture with high accuracy, even for a hobby.
