Triple Feed Patch Directional Circularly Polarized Antenna 5.8GHz 9.4 dBi SMA/RP-SMA Plug

-The Triple Feed 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 just directly perpendicular to the patch but also off-center.
-Cheap and easy to manufacture with high accuracy, even for a hobbyist.
