Description:
The 5.8G three-phase feed flat panel antenna is a high-performance directional circularly polarized flat panel antenna designed by foreign model friends Maarten Baert and Robin Theunis based on the three-phase feed flat panel antenna. This antenna uses 7 coupling plates, so it can achieve very high gain. This antenna is not recommended for FPV because the antenna has a narrow beam width, but it is very suitable for long-distance flight.

Specifications:
Antenna color classification: black, red (optional)
Interface: SMA inner screw inner needle, SMA inner screw inner hole
Gain: 14dBi
Center frequency: 5.8G Bandwidth: 950MHZ+-100MHZ
Impedance: 50 ohms
Polarization: left-right circular polarization
Standing wave ratio: <1.5
Axial ratio: 1.10 10.83 dB)
Half-power beamwidth: 30°
Radiation efficiency: 74%

Features:
1. Excellent radiation efficiency. Unlike other flat antennas with glass fiber substrates, the efficiency loss in the 5.8G band is serious. Moreover, the feed network loss of many whole-array antennas is large. But the design of the coupling plate can reduce the loss of the feed network.
2. Excellent axial ratio. Not only perpendicular to the plate, but also offsets the center point.
3. High gain, although it does not reach the theoretical gain value, this is because maximizing the gain will result in high side lobes and low axial ratio.
4. Extremely low side lobes, almost all of which can be concentrated on the main lobe. Although some gain is sacrificed, the width of the main lobe is increased.
