Pagoda Array FPV Antenna 150mm Triple Feed Patch 5.8GHz 14dBi

Specifications: Center frequency: 5.8 GHz Bandwidth: 660 MHz (5.47 ? 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 Degree (horizontal and vertical) Radiation efficiency: 75Percent Features: 1. Good radiation efficiency. Most FR4based 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 offcenter.   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
