Specifications Center frequency 5 8 GHzBandwidth 660 MHz 5 47 6 13 GHz Matching S11 30 dB VSWR1 065 Axial ratio 1 05 0 38dB Antenna gain 14 4 dBiHalf power beam width 30° 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 ｅlements 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 Antenna1 x extension cable 2 x adapter
