1. 5.8G three-phase feed flat panel antenna is a high-performance directional circular polarization flat panel antenna based on the design of three-phase feed flat panel antenna 2. Excellent radiation efficiency. Unlike other flat panel 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 coupled flat panel can reduce the loss of the feed network 3. Excellent axial ratio. Not only perpendicular to the flat panel, but also offset the center point 4. High gain, although it does not reach the theoretical gain value, this is because maximizing the gain lead to high side lobes and low axial ratio 5. 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 Gain: 14dBi Center frequency: 5.8G Bandwidth: 950MHZ+-100MHZ Impedance: 50 ohms Polarization: left-right circular polarization Standing wave ratio:Less than 1.5 Axial ratio: 1.10 10.83 dB) Half-power beamwidth: 30° Radiation efficiency: 74% (The product appearance and printed words depending on the batch, but this does not affect use) Color:Red Material:plastic Package Contents: 1 * Antenna Kit Only the above package content, other products are not included.
