58GHz FPV Triple Feed Patch Antenna RCmall 94dBi High Accuracy SMA Male to SMA Male Cable Adapter Directional Circularly Polarized Antenna for FPV Racing Drone

Patch Antenna with Adapter and Dummy Load Link: https://www.amazon.com/dp/B07DXVZ917 RCmall 5.8GHz 9.4dBi Triple Feed Patch Antenna, High Accuracy SMA Male to SMA Male Cable Adapter, Directional Circularly Polarized Antenna for FPV Racing Drone 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. 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% Size: 59.7 x 59.7 x 99.1mm Color: black Package Included: 1 x Triple Feed Patch Antenna 1 x semi-rigid coax (SMA male – SMA male) If there is any problem please contact us feel free.
