Realacc Triple Feed Patch-1 5.8GHz 9.4dBi Directional Circular Polarized FPV Pagoda Antenna
The Triple Feed Patch antenna is a directional circularly polarized antenna
Good radiation efficiency. Most FR4-based patches have terrible efficiency because FR4 is very lossy at 5.8 GHz.
Radiation pattern:
Measurements:
Center frequency: 5.8 GHz
Matching: S11 < -20 dB, VSWR < 1.22 (at center frequency)
Antenna gain: 9.4 dBi
Radiation efficiency: 83.5%
Features:
Diameter of small disk: 2.46cm
Features:
Good axial ratio, not just directly perpendicular to the patch but also off-center
Note: The PCBs must use 1.0 mm thickness FR4 material
