Specifications:
Center frequency: 5.8 GHz
Bandwidth: 660 MHz (5.47 u2013 6.13 GHz)
Matching: S11 < -30 dB, VSWR < 1.065
Axial ratio: 1.05(0.38dB)
Antenna gain: 14.4 dBi
Half power beam width: 30° (horizontal and vertical)
Radiation efficiency: 75% Features:
1. Good radiation efficiency. Most FR4-based patches have terrible efficiency because FR4 is very lossy at 5.8 GHz. Additionally, most array antennas have higher losses in the feed network. This design uses coupled patches to keep the feed network simple and reduce these losses.
2. Exceptionally good axial ratio, not just directly perpendicular to the patch but also off-center.
3. High gain, though not as high as the theoretical gain of an array with 7 uff45lements. This is because maximizing the gain would result in high sidelobes and a poor axial ratio.
4. Very low sidelobes, almost all energy is concentrated in the main lobe. This increases the width of the main lobe, at the expense of some gain. Package included:
Tested to 5 miles so far and holds a very solid video link with Pagoda 2 + 600mw. Works better than triple feed patch certainly but is borderline absurd in size.
Harder to aim than x-air, pepperbox, and triple feed. I wouldn't recommend for mini quads unless you have diversity. Still easy enough to aim using just your head. I don't think you need an antenna tracker or diversity to use it.
