Description
Gofly Triple Feed Patch Antenna The Triple Feed Patch antenna is a directional circularly polarized antenna, which was designed by Marteen and Robin Theunis. 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.
