he Triple Feed Patch is a high gain directional circularly polarized antenna. The antenna is based on an open source design, the author of which is Maarten Baert, who, among other things, designed the widely used Pagoda type antenna. The antenna is significantly smaller than its sibling the Triple Feed Patch Array and can therefore be comfortably worn on FPV goggles.
The antenna has two SMA connectors, one of which is terminated with a terminator. Depending on the antenna connection, it can be used as an RHCP or LHCP antenna.
