The GEPRC Triple Feed Patch Array Antenna is a directional circularly polarized antenna based on the original Triple Feed Patch antenna. It uses an array of seven coupled patches, resulting in significantly higher gain. Since the beamwidth is relatively narrow, this antenna is not recommended for general FPV, but it performs very well for a long-range flight. Most FR4-based patches are efficient because FR4 is very lossy at 5.8 GHz. Also, most array antennas have higher losses in the feed network. The design uses coupling patches to keep the feed network simple and reduce these losses.

• Very good axial ratio, not only directly perpendicular to the patch but also eccentric
• High gain, but not higher than theoretical gain for an array with 7 elements
• Good radiation efficiency
• Very low side lobes
