FlyMod Triple Feed Patch is a directional patch antenna with circular polarization, made on the basis of an open project of Belgian engineers Maarten Baert and Robin Theunis, and modified by FlyMod team.
Despite the changes made, the antenna corresponds to all the parameters of the original project, as some manufacturers violate the technology of the distance between the plates, which affects the range of reception.
Main features
Good radiation efficiency
Good axial ratio (not only directly perpendicular to the patch, but also off-center)
The center frequency may vary slightly between batches as a result of changes in the dielectric constant of FR4. Also, not all grades of FR4 have the same dielectric constant. Frequency shifts up to 100MHz are normal
Changes from FlyMod
Removed mounting holes (lugs) to reduce size. They did not affect antenna performance and were not used in FPV
Does not require a terminator plug as the antenna has a single SMA output and only built-in right-handed (RHCP) polarization
