Excellent Long Range Directional Circular Polarized Antenna. Must Try! Designed By Maarten Baert & Robin Theunis.
Features: Good radiation efficiency. Most FR4-based patches have terrible efficiency because FR4 is very lossy at 5.8 GHz 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
Specifications: Center frequency: 5.8 GHz Bandwidth: 660 MHz (5.47 6.13 GHz) Matching: S11 < -20 dB, VSWR < 1.22 (at center frequency) Axial ratio: < 1.3 Antenna gain: 9.4 dBi Half power beam width: 55 (horizontal and vertical) Radiation efficiency: 83.5% Diameter of large disk : 5.94cm Diameter of small disk: 2.46cm
Package included: 1 x Triple Feed Patch-1 5.8GHz 9.4dBi Directional Circular Polarized FPV Antenna 1 x Extended cable for RPSMA Connection
