Good radiation efficiency.The design uses coupling patches to keep the feed network simple and reduce these losses.Good reception, good for mid and long-range flying, a great antenna to use with diversity 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. This is because maximizing gain results in high side lobes and poor axial ratio. Very low side lobes, almost all the energy is concentrated on the main lobe. This increases the width of the main lobe, but adds some gain. Suit for fpv goggle such as Skyzone 02s Eachine EV800D EV200D EV100 VR006 FatShark HDO HD3 Aomway Commander.Comes with a nice compact storage box The 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 rather narrow, this antenna is not recommended for general FPV, but for long range flight it performs very well.
