Specifications: Center frequency: 5.8 GHz Bandwidth: 660 MHz (5.47 a?? 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?ﾣ (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 ???lements.
? ?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:
1 x 150mm Triple Feed Patch 5.8GHz 14dBi Pagoda Array FPV Antenna 1 x extension cable? 2 x adapter ?
