5.8GHz Triple-Feed Circularly Polarized Patch Antenna – SMA/RP-SMA, Directional, for FPV Goggles & Drones

Description

Features:   The Triple Feed Patch antenna is a directional circularly polarized antenna. Good radiation efficiency. Most FR4-based patches have terrible efficiency because FR4 is very lossy at 5.8 GHz. Good axial ratio, not just directly perpendicular to the patch but also off-center. Cheap and easy to manufacture with high accuracy, even for a hobbyist.   Description: Cheap and easy to manufacture with high accuracy, even for a hobbyist.   Specifications: Center frequency: 5.8 GHz Bandwidth: 660 MHz (5.47 – 6.13 GHz) Matching: S11 < -20 dB, VSWR < 1.22 (at center frequency) Axial ratio: < 1.3 Antenna gain: 9.4 dBi Half power beam width: 55° (horizontal and vertical) Radiation efficiency: 83.5% Weight:20.7g Color: black       1 x Black Triple Feed Patch Antenna  1 x semi-rigid coax (SMA male – SMA male/ RP SMA male – SMA male as  your choice)    Note:  Fatshark Goggles and other component is not included.
