Triple Feed Patch Array The Triple Feed Patch Array antenna is a directional circularly polarized antenna based on the original Triple Feed Patch antenna. It uses an array of seven linked patches, resulting in significantly higher gain. Since the beam width is quite narrow, this antenna is not recommended for general FPV, but it works very well for long distance flights. Features 1. Good radiation efficiency. Most FR4 based patches are very effective because FR4 is very lossy at 5.8GHz. Also, most antenna systems have higher losses in the power supply network. The design uses connection patches to keep the power network simple and reduce these losses. 2. Very good axial ratio, not only perpendicular to the patch, but also eccentric. 3. High gain, but not higher than the theoretical gain for a 7-element array. This is because maximizing gain results in high side lobes and a poor axial ratio. 4. Very low side lobes, almost all energy is concentrated in the main lobe. This increases the width of the main lobe but adds some gain. Specifications: Center frequency: 5.8 GHz Bandwidth: 660 MHz (5.47 - 6.13 GHz) Adaptation: S11 < -20 dB, VSWR < 1.22 (at mid frequency) Axle ratio: < 1.1 Antenna gain: 14.4dBi Connector: RP-SMA/SMA Half power beam width: 30° (horizontal and vertical) Radiation efficiency: 75% Large disc diameter: 150 mm
